How Do We Measure?

Dust CADR Industry-standard measurement by the Association of Home Appliance Manufacturers (AHAM). CADR is measured by CFM (cubic feet per minute) on the amount of clean airflow that comes from the air purifier. The higher the CADR score, the quicker an air cleaner can remove dust in the air thus less cleaning is needed in the house. Take note that not all models are tested for CADR.
Pre-filter/ HEPA filter As dust particles are about 2.5 to 100 µm in diameter, a pre-filter would have no issue dealing with it. To qualify in our list, the filter must be durable enough to trap a great deal of dust, hair, and debris week in, week out. At the same time, the filter must protect the HEPA filter by reducing the number of particles coming through. Having a High Efficiency Particulate Air (HEPA) filter is critical. It can help people suffering from allergies or asthma breathe better. No compromisation on quality whatsoever.
Room size/ Coverage As dust can be found on every corner of the room, a HEPA air cleaner uses filters to remove airborne dust and circulate clean air. The higher the number of air changes released per hour, the smaller the purifying range an air purifier can cover in a room. We typically measure the room coverage at 2 air changes per hour. However, an extra point would be given for the model can cover well at 4 air changes per hour.

How to Choose the Best Air Purifier for Dust

It Is always good to have an air purifier running in the background when cleaning the house. An air purifier can capture dust that stirs back up in the air and prevent it from settling on the couch, shelves, bed, wall, floor. However, some model requires greater effort in removing particulate matters due to their limited capacity. Instead of spending countless hours reading and comparing every model, here are the key features you should look for when buying the best air cleaner for dust.

  • Filtration stage - To be part of the best air filter for dust, you will need at least 3-stage filtration. This includes a pre-filter, a HEPA filter, and a carbon filter. Never settle for less.
  • 2-in-1 pre-filter - Like a normal pre-filter but comes with an extra carbon sheet. It is designed to block large irritants plus mild smoke and odors. Since the 2-in-1 pre-filter is not washable and reusable, priority should be given to an air purifier that comes with a permanent pre-filter.
  • True HEPA filter - Only go with a government standard filter that captures at least 99.97% of the airborne particles as small as 0.3 microns. All HEPA filters must be made according to the strict regulation set by the United States Department of Energy (DOE). True HEPA filters are not washable and must be replaced annually.
  • HEPA-type filter - A lower-grade version of the True HEPA filter that should not be on your consideration list. HEPA-type filter captures 99% of the microscopic particles as small as 2 microns. Typically, you will find a HEPA-type filter in a cheaper air cleaner.
  • Activated carbon filter - A non-washable, deodorizing filter that focuses solely on capturing gases and odor via chemical absorption. The perfect complement to the existing HEPA filter and a must-have filtration.
  • Ultraviolet light (UV) - Use invisible electromagnetic radiation to sterilize bacteria and viruses. UV light technology is 100% safe technology and works well with any mechanical filter. It is completely optional, but no harm in having one.
  • Ionizer - AKA ionic filter or a negative ion generator. It disperses millions of negative ions into the air. The (-) ions will merge with (+) positive ions particles. The combined ions will drop due to the increased weight allowing the filter or plate to collect the irritants. Take note that an ionizer is not an ozone generator, although some manufacturers would market it as one. It must comply with the regulation set by the California Air Resources Board (CARB) on the ozone emission concentration level.
  • Warranty - Go through what does the limited warranty covers as every manufacturer has a different interpretation. Find out how responsive is the customer service and the nearest service center location. Do not settle for a model that does not warrant poor workmanship and motor parts.
  • Airflow speed - The higher the airflow delivery rate, the more air will be pulled into the machine. With more air gone through filtration, more dust will be removed, and quicker clean air can be achieved.
  • Cost of ownership - Pick a model that you are comfortable paying. A good dust air purifier can be as low as 100 dollars. If you go for the top-tier model, the price can go all the way up to 2000. The same goes for the filter replacement cost. Depending on the filter grade, there will be a recurring cost from 100 dollars onwards.
  • Dimension - Knowing where you want to place the air cleaning device can help you make the right purchase decision. A smaller but less powerful model will be the sensible option if you plan to use it in a bedroom or a small studio.
  • Noise level - The more powerful the air purifier, the more noise the motor fan will generate. Most air cleaning devices will have a noise output not more than 60 dB. If you plan to use it during sleep or work, go with a model with the lowest noise output under 30 dB. The availability of sleep mode is a good gauge of how silent an air purifier can go.
  • Power consumption - Most dust air cleaners have reasonably low power usage. That said, leaving it running 24x7 will increase the electricity bill ever so slightly. If you are particularly on energy output, pick a Energy Star rated model.
  • Auto mode - Relies on the built-in sensor for autonomous operation. With Auto mode enabled, the air purifier will only increase the fan speed when a high volume of dust is detected. Otherwise, it will remain at the lowest speed. A handy feature in our book.
  • Sleep mode - An optional feature that relies on the light sensor for auto-activation. Dim the indicator light and lock the fan speed to the lowest for minimal fan noise.

Winix 5500-2 air purifier is a great dust remover at a fraction of the cost (under 200). The 15 x 23.6 x 8.2 inches black housing fits nicely in most home decor without occupying much space. The front air quality indicator will change from blue with good air quality, yellow when moderate, and red with bad air quality. Circling the exterior, you will find both air inlets located at the side with a top air outlet hidden behind the back. A typical console air purifier setup with a bottom to top air circulation. Build quality and fitting is solid, with no chance of captured dust and allergens escaping. An important trade as most budget air purifiers tends to fall apart after a couple of years.

One of the best dust air purifiers costs less than 200 dollars after discount. For the low price, you'll get a 4-stage PlasmaWave filtration, decent CADR output, and tons of premium features.

Winix 5500-2 is on the cheaper price end yet comes with a good 360 square feet air cleaning coverage. It can support a larger bedroom, living room, nursery room, and even a dusty storeroom. The same goes for the decent 226 cfm airflow delivery rate, dust CADR at 243 cfm, pollen at 246 cfm, and smoke at 232 cfm. In a medium-sized room, leave the air purifier on for a couple of hours, and you will feel a noticeable less dusty air quality with less breathing irritation. Noise level is reasonably quiet at 26.6 to 60+ decibels with power usage between 5 to a max of 90 watts. Effective yet efficient all-rounder output. The multi-stage filtration will quickly alleviate dust allergic reactions, particularly sneezing and runny nose at turbo speed. If you plan to leave Winix 5500-2 running throughout the night, set it at turbo speed for a couple of hours and revert to auto/ sleep mode before hitting the sack.

Moving to usability, dust remover Winix 5500-2 is very easy to use with 4 selectable fan speeds and remote control (rare in its class). A convenient function that lets you manage the air purifier in the comfort of your bed or sofa. You will also find premium features like auto mode, sleep mode, timer, and filter change indicator in the spec sheet. The auto mode enables autonomous purifying that will only set higher speed when an increase of pollutants is detected. Auto Sleep mode works well thanks to the VOC and light sensors that automatically activate when there is no light source. Again, a rare autonomous feature is handy to set when you're away for work or about to sleep. The filter change indicator reminds you to change the filter when worn out.

Here is the run-through of Winix 5500-2 specification:

  • Dust free CADR - 243 cfm
  • Room Coverage - 360 sq. ft.
  • Fan Speed - 4 with Auto Mode
  • Air Filtration - Pre-filter, True HEPA filter, AOC Carbon Filter, PlasmaWave Technology
  • Warranty - 2 years

The good old permanent pre-filter works exceptionally well with the True-HEPA filter. When air is drawn into the ventilation, the pre-filter will capture all inflow dust elements, including hair, debris, lint, and dirt. Without the large particles clogging up the filter, the True HEPA filter can trap finer particles at 99.97% efficiency as small as 0.3 microns. AOC Advanced Granular Carbon adsorbs indoor smoke and odors from cigarettes, cooking, pets, and even body odor. PlasmaWave technology produces Hydroxyls to help break down allergens, germs, and odors for the filter to capture. It is optional where you can disable it at any point of the purification. With more and more dust taken down in the air, the likelihood of dust bunnies forming is dramatically reduced. You do not have to vacuum every day as there is less dust accumulation in the house.

Let's look into the only major con we could think of. Winix 5500-2 air purifier is not so "affordable" in the filter department. Like most Winix models, the filter replacement set can be costly to replace in the long run at around 80 dollars annually. Thankfully the permanent pre-filter is washable; you do not have to replace it like the 2-in-1 type. The built-in sensor will sometimes slow to react, but not to the point that it is unusable. If money is an issue, consider the cost-effective option 5300-2 for those that don't mind dropping a few features. Last nitpicking, Winix 5500-2 is also not the most silent air purifier out there. Still, given its size and dust removal capability, we have no issue recommending one.

In short: One of the best dust air purifiers costs less than 200 dollars after discount. For the low price, you'll get a 4-stage PlasmaWave filtration, decent CADR output, and tons of premium features. ⚠️ Buy this if you want a solid yet inexpensive dust air purifier.

Medify MA-40 is a Florida-based and woman-founded company that can curb your dust allergies. More importantly, it is a prominent dust air purifier that does not produce any harmful byproducts. Unlike other compact air cleanings, Medify Air MA-40 focuses on performance and practicality thanks to the large horizontal air inlet design house in a tall 22 inches height body. The big ventilation allows more dust to be collected within a short period of time, so there is less risk of you inhaling the airborne irritants. At 15.6 pounds in total weight, Medify Air MA-40 is bulky but not overly, so that will eat up the entire interior space. You can still move it around effortlessly for multi-room air cleaning when needed to.

A great dust remover air purifier that is not the cheapest to own and maintain. The strong airflow distribution will compensate for the lack of Auto mode.

Moving to the controls, we are a big fan of the tempered glass panel, and Medify Air MA-40 does not disappoint. It comes with a 4 preset timer to manage the air purifier runtime and a filter replacement indicator that alerts you to change the filter when it is due. The child lock locks the control from meddling kids and 3 fan speeds manual adjustment. Fitting is on par with all the top-tier models with no misalignment and off-gassing. There is no chance of the captured dust escaping and causing a sneezing frenzy. The standard lifetime warranty from the manufacturer is a good testament to its build quality. Still, you will have to subscribe to the Medify Air filter set.

Given the robust airflow distribution, the noise level is not Medify Air MA-40's strongest suit. It is at a rather steep 46 dBA "sleep mode" while noise could go as high as 66 dBA (slightly higher than normal conversation). You could still use it in the bedroom to remove dust as long as it is placed further away from you. Being an Energy Star Rated model, power usage is only at 54 watts per hour despite the strong airflow delivery rate. No problem running Medify MA-40 efficiently and effectively 24x7 to capture airborne dust as long as you can suppress the white noise.

Here are the key features of Medify MA-40:

  • Dust free CADR - 330 cfm
  • Room Coverage - 840 sq. ft. (2 air changes per hour)
  • Fan Speed - 3 with night mode
  • Air Filtration - Pre-filter, H13 True HEPA filter, Activated carbon composite filter, Ionizer
  • Warranty - Lifetime

Here is what makes Medify Air MA-40 a great dust removal machine. You have the dual intake pre-filter that traps large particles like dust mites, hair, fibers, and lint from passing through straight off the bat. Next, the medical-grade HEPA filter removes 99.9% of irritants as small as 0.1 microns. The top-graded H13 HEPA filter can even target microscopic irritants like bacteria and virus carriers that most couldn't. The carbon filter with carbon pellets absorbs cooking, pet odors, musty mold, and harmful toxins e.g. VOCs, asbestos, radon, formaldehyde, benzene. A welcome addition to the pre-existing filters. Lastly, an optional ionizer diffuses negative ions and latches on positive ions irritants in the air. The combined, heavier particles will drop, allowing Medify Air MA-40 to capture the pollutants into its filtration.

Thanks to its comprehensive purifying coverage and strong airflow distribution, Medify MA-40 can swiftly take the dust out of the air. Catered for large room sizes, anticipate a max of 840 square feet coverage in 30 minutes or 2 air changes per hour. Top up the air changes to 4 or every 15 minutes; the air cleaning will still drop to a healthy 420 square feet of coverage. Most people will run Medify MA-40 in the bedroom, living hall, or basement to deal with dust build-up as they spend most of the time there. Common areas like the kitchen or garage will be fine as long as you have the space to put it. Medify Air MA-40 CADR is also on par with the airflow output. Test under AHAM standard guidelines, the dust CADR is at an impressive 330 cubic feet per minute. Outscored most dust air purifiers listed here; it will handle dust very well.

While it seems like we are all singing praises, the Medify Air MA-40 air purifier is not without its fault either. There is no AQ indicator particle sensor to support autonomous mode for the price you paid. Not acceptable given cheaper alternatives like 5500-2 manage to bundle with it. The dual filter setup is costly to replace and can be overwhelming if you are not careful. You will have to change the filter set every 2,500 hours or 3-4 months. Again, the noise level is on the louder end, but that should not be a big deal for some. If money is tight, there are many smaller air cleaners to cherry-pick from. Understand that non will come close to Medify Air MA-40 dust caliber with a medical-grade HEPA filter.

In short: A great dust remover air purifier that is not the cheapest to own and maintain. The strong airflow distribution will compensate for the lack of Auto mode. ⚠️ Buy this if you want a well-rounded dust air purifier and don't mind the cost.

Hyper-allergic to dust mites yet surrounded by the pesky Lil thing left to right? Coway Airmega 300 is here to save the day. A high-performance and modernly designed air purifier with a front real-time air quality indicator. It comes in 4 different variants that vary in the specification. Coway Airmega 300 is the cheapest, although the selling price would indicate otherwise. Airmega 300 is not overly bulky with the 13.6 x 21.2 x 13.6 inches body size and 21.4 lb weight. We would appreciate built-in casters like in IQAir than the four legs, but it's not a big deal as long as you are not moving it around. For the price point, you're getting a well-made air purifier encircled by two side air inlets. The front dotted circle indicator will change four colors according to surrounding air quality (good, moderate, unhealthy, and very unhealthy). Visually stunning yet serve an actual purpose. Build quality is up there with the best, as you would expect no less at this price point. An extended 5 years warranty comes standard in the package that protects any manufacturing defects and non-wearable parts. Not quite Medify Air level, but still better than 99% of air cleaners out there.

Outstanding 4-stage HEPA filtration with a high 1256 sq. ft. purifying coverage. Tested and proven dust removal machine for everyday use.

Airmega 300 has many other practical features that enhance the usability of the air cleaner. You can easily set 1, 4, or 8 hours of interval time to stop the air cleaner operating via the control panel. There is also selectable low, medium, high speed, and Auto mode that automatically adjust the fan speed according to surrounding air quality. A separate Pre-filter and MAX2 filter lifetime indicator reminds you to clean (shorter interval) or replace the filter (longer interval). Manual Sleep mode will lower the light intensity and lock that fan speed to low to keep the noise down. Even a dedicated light button to help reduce glaring at night.

Being an Energy-star rated model, Coway Airmega 300 air purifier only consumes around 6 watts of energy when running at the lowest speed. It is even lower than most portable air cleaners despite the strong airflow output. Besides the energy-efficient operation, the noise level is also Airmega 300 strong suit between 22 to 52 decibels. You can run it quietly in the bedroom when trying to get some rest after a long day (with sleep mode). Coway Airmega 300 is also ideal for work and leisure use with the auto mode selected. Once set, there is no need to manage the air purifier as it will clean airborne dust in the background autonomously.

Here is the key specification of the Airmega 300 air cleaner:

  • Dust free CADR - 260 cfm
  • Room Coverage - 1256 sq. ft.
  • Fan Speed - 3 with Auto Mode
  • Air Filtration - Pre-filter, Green True HEPA filter, Activated carbon filter
  • Warranty - 5 years

One pre-filter is never enough to deal with dust. That's why Airmega 300 comes with two permanent pre-filter, one on each side of the air inlet. With endless dust particles in the air, the pre-filters catch PM10 particles and prevent them from damaging the other filters. The permanent filters are also washable and reusable for many years to come with proper care. The well-protected Max2 HEPA traps dust allergens as small as 0.3 microns with 99.97% efficiency, e.g., mold, pollen, pet dander, and germs. Finally, the activated carbon filter removes chemical smoke and odors that the HEPA filter cannot capture. The entire purification is 100% mechanical, so no traces of ozone or chemical byproducts will ever be produced. Perfectly safe for an asthmatic or hypersensitive person, particularly to dust.

Cater for large room sizes, Airmega 300 can cover 1256 square feet of room space at 2 air changes per hour or 628 square feet at 4 air changes per hour. We recommend keeping the air purifier at the highest air changes when the room feels dusty and switching it back to low when air quality has improved. All three dust, pollen, and smoke CADR are equally impressive at the 260 cfm benchmark. Great for all open spaces, e.g., living hall, office, bedroom, or an entire floor with doors wide open.

Airmega 300 air purifier is far from cheap despite the lowest variant and a heavy 100-150 discounted price. Expect to pay slightly under 500 for the complete package. To add it up, all the excellent features we mentioned do incur an extra cost, especially in the filter department. You are looking at around 100 dollars annually on the MAX2 filter replacement cost with 12 hours of daily runtime. Running it all day further increases the annual filter cost depending on how bad the indoor air quality is. The double pre-filters also require double effort to clean, which can be annoying in the long run. If you just want a simple air cleaning device that is easier to maintain, there are other cheaper dust air purifiers in this list with good discounts.

In short: Outstanding 4-stage HEPA filtration with a high 1256 sq. ft. purifying coverage. Tested and proven dust removal machine for everyday use. ⚠️ Buy this if you want a premium dust removal air purifier that is very easy to use and can keep up with the high recurring cost.

The mother of all air purifiers, Blueair Pro XL is the best air purifier for dust removal for a good reason. To start, you have the segment-best dust clean air delivery rate in all residential air cleaners verified by AHAM. The official Dust CADR is at 950 cfm, followed by Pollen 900 cfm and 800 cfm for smoke. That's four times the clean air output of a Winix air purifier featured here. Tally with that is the excellent airflow distribution and 1180 square feet purifying coverage powered by 3 German-engineered fans. Yes, three built-in fans that work coalesce with each other to pull in dust particles and allergens for filtration swiftly. Blueair Pro XL air purifier is ideal for large room-size, e.g., offices, living hall, basement, garage, and kitchen. It might be overqualified on the small bedroom unless you live in a mansion.

Set aside the price tag and very expensive filter replacement cost, Blueair Pro XL is the ultimate dust removal machine to go for. No other air cleaner can match the strong airflow and crazy high dust CADR (950 cfm).

Let's look into the sweet 3-stage HEPASilent technology and its specification:

  • Dust free CADR - 950 cfm
  • Room Coverage - 1180 sq. ft.
  • Fan Speed - 3 with Auto Mode
  • Air Filtration - HEPASilent Technology with Blueair Pro Particle Filters and Pro SmokeStop Filter
  • Warranty - 5 years

As mentioned earlier, Blueair Pro XL's powerful 990 cfm airflow delivery rate can cover 1180 square feet of room space at high air changes per hour. The Trio encapsulated particle-charging chamber ionizer electrostatically charges particles like dust mites, pollen, pet dander, mold spore that are drawn into the filtration. Either Trio Blueair Pro3 Particle Filter will trap the adhesive pollutants up to 99.97% of irritants as small as 0.1 microns. You have the trio Pro SmokeStop filter for smoke particles that adsorbs chemical fumes and odors, including radon, ammonia, CO, CO2, VOCs, and ozone. On top of the excellent filtration, Blueair Pro XL filter media is made from waterproof, natural antibacterial polypropylene fibers that inhibit microbes' growth. The V-shaped filter design further prevents trapped contaminants and dust from escaping. Minor attention to details that are uniquely Blueair.

One of the few air purifiers we recommend for places with high air quality index (AQI). Blueair Pro XL is the perfect machine you could get against the dustiest, dirtiest home. It is also the only model in the pro series with the Air Intelligence Module. With it, the auto mode automatically adjusts the fan speed when a high level of pollutants is detected. Operational noise is workable for all-day use; expect a subtle noise level between 32 to 58 decibels. On the flip side, energy usage is high, with 256 watts per hour. If you are living in a state with high household electricity prices, e.g., Hawaii, Blueair Pro XL can create a burden on your electrical bill.

Blueair Pro XL is not without some drawbacks. The powerful airflow and high CADR are reflected in the bulkiness and weight. You will not want to carry this giant 20 x 44 x 10 inches, 71 pounds weight device around the house. There is also an expensive price tag and high recurring filter cost to contend with. The trio filter set cost can go as high as 1k, which is not attainable for most people. There is no Wi-Fi pairing, remote control, or timer in the package for the price you paid. Unless you are staying in an industrial area or have a severe dust allergy, opt for the smaller Blueair Pro L or Pro M air cleaner. Likewise, most households will be content with Blueair Classic 605 air purifier.

In short: Set aside the price tag and very expensive filter replacement cost, Blueair Pro XL is the ultimate dust removal machine to go for. No other air cleaner can match the strong airflow and crazy high dust CADR (950 cfm). ⚠️ Buy this if you want the absolute best dust air purifier money can get.

The classic dust air cleaner model that needs no introduction. Blueair 605 has been around for ages for its impeccable air filtration performance. The clean white powder-coated panel is pleasing to the eyes yet does not sacrifice functionality and airflow circulation. It hosted some of the biggest filters in the market, which allows more dust particles to be captured at a go. However, the trade-off of being the biggest air cleaner in the Blueair Classic lineup, the 20 x 26 x 13 in dimension and 35 lb weight, is very bulky and heavy to move around. Thankfully there are four casters to ease the movement as long as it is kept on the same floor. Ending with the tour is the top-notch build quality made from eco-friendly materials. Like Airmega, this Sweden-built air cleaner comes with an assuring 5 years warranty that guarantees trouble-free ownership for years to come.

Classic model with Blueair trademark HEPASilent Technology. Expensive price tag but comes with a strong airflow and a super-wide purifying coverage.

As for the controls, Blueair 605 is straightforward to use with a single button for fan speed, a filter reset button after you have changed the filter, and a Wi-Fi button. The Wi-Fi button opens up advanced features only available on your smart devices. Via the Blue Friend app (available on Google Play Store or iTunes), you can use the smartphone to control the fan speed remotely, enable/ disable LED light, or the night mode. You can even lock the controls (child lock) to prevent accidental adjustment, schedule hours or days of operation, and track usage and logs via the apps. There are also other supporting features that you can play around with. Still, everything can be set up via the air purifier control panel for basic dust cleaning functionality.

Here are the key highlights of Blueair Classic 605:

  • Dust free CADR - 500 cfm
  • Room Coverage - 775 sq. ft.
  • Fan Speed - 3
  • Air Filtration - HEPASilent Technology with Particle Filters and SmokeStop Filter
  • Warranty - 5 years

Combining the effort between electrostatic and mechanical filtration, it all begins when the encapsulated particle-charging chamber electrically charges any inflowing pollutants. The charged impurities will adhere to the low dense, gradient structure particles filter at 99.97% capturing efficiency. This includes dust, hair, fabric fiber, lint, dust mites, dead insects, mold spore, pollen, bacteria, and viruses as small as 0.1 microns. The SmokeStop Carbon filter effectively traps toxic gas and odors. It can even reduce the ozone concentration level in a room. Adding to the premiumness, all filters are ultrasonically bonded with antibacterial polypropylene fibers that inhibit the growth of mold and mildew. With a maximum of 650 cfm airflow delivery rate, Blueair 605 can cover up to 775 sq. ft. of room size with certified 500 cfm dust-free CADR, 640 cfm pollen-free CADR, and 500 cfm smoke-free CADR. The strong output is ideal for large room sizes or a person with asthma, severe dust allergy, or respiratory problems.

Blueair 605 can be reasonably cost-efficient and silent even with impressive purifying coverage. At the lowest speed, energy usage is at 15 watts with a noise level of 23 decibels. Suitable for work and night use when you need clean air yet do not want any noise distraction. At maximum speed, energy usage is at 100 watts with a noise level exceeding 62 decibels. Only use this mode when your allergies start flare-up due to the dusty environment. You can also rely on the efficient auto mode provided if you have the addon Blueair Aware monitor (more on this later).

Let's talk about Blueair's commonly perceived cons. First, the expensive selling price is the biggest stumble block for most folks as they can't afford a 600 dollars model. You can downgrade to 405 or 205, but even those are also on the pricier side. The filtration set is non-washable, so you will have to fork out around 460 dollars depending on the hours of operation and how dirty the air is. The lack of autonomous support like Auto mode, Sleep mode, AQ sensor is also a big bumper at its price point. You will need to purchase Blueair Aware monitor just to get some of the features mentioned. Blueair 605 air purifier can freely reduce dust build-up in the house and free up vacuuming time at the end of the day. A pretty sweet deal if you could afford one.

In short: Classic model with Blueair trademark HEPASilent Technology. Expensive price tag but comes with a strong airflow and a super-wide purifying coverage. ⚠️ Buy this if you want the goodness of a Blueair but not to the extent of Pro XL.

Most GermGuardian models offer attractive pricing with some compromisation on performance. The CARB-approved, Energy Star rated GermGuardian AC9200WCA is the odd one out. For the price of around 300 after rebate, it is an excellent home air purifier for dust removal. It comes in at 17 inches in width, 27 inches in height, 9.8 inches in depth, and 20.7 lb in weight. GermGuardian AC9200WCA will take up some room space. However, you can still easily fit in a bedroom, garage, studio apartment that needs air cleaning. Unlike most GermGuardian tower air purifiers that can be placed on a table, AC9200WCA is only limited to the ground utilizing a bottom-to-top air circulation style. The detachable panel is easily removable for a quick filter change or vacuuming to clear out the collected dust. Overall, the fitting is good, with no signs of poor workmanship or off-gassing. The semi-long 3 years warranty period is a good assurance of its long-term durability.

The perfect machine to counter a dusty home. Come with 5-stage filtration that pair well with the strong airflow delivery rate and CADR.

Next, let's move to GermGuardian AC9200WCA simple controls. You have a standard 3 fan speed that you can select based on the dust level. A timer with preset 2, 4, 6 hours, dedicated UV-C light, and ionizer button that allows you to enable/ disable the function when not needed. The filter change indicator will alert you when the filter or UV-C light needs changing. Nothing out of the ordinary, everything included and laid out as intended.

Continue with GermGuardian AC9200WCA 5-stage filtration and specification:

  • Dust free CADR - 310 cfm
  • Room Coverage - 378 sq. ft.
  • Fan Speed - 4 with Auto Mode
  • Air Filtration - Pre-filter, True HEPA filter, Activated Carbon Filter, UV-C Light, Ionizer
  • Warranty - 3 years

To complement the airflow delivery rate, you will need a good set of filters, and AC9200WCA does not disappoint. The permanent and reusable pre-filter can capture a large speck of dust while protecting the HEPA filter from damage by the large contaminants. Next, the true HEPA filter traps fine particles like mold, pollen, pet dander that often travel with the dust. The standalone activated carbon filter will focus on smoke, chemical fumes, and odors from cigarettes, food, toilet through adsorption. You have the germ-killing UV-C light for bacteria and viruses that eliminates all microbes by altering their DNA and preventing them from growth. Finally, the ionizer electrostatically charges and weighs harmful particles down for the filter to capture. All in all, the combined airflow performance can deliver up to 310 cfm dust CADR with a respectable 378 sq. ft. purifying coverage. Ideal for medium to large room sizes when AC9200WCA is kept on high speed. The noise level and power consumption are decent for everyday use. You can use it on low-speed mode during the night without having to give up on the dust removal performance.

GermGuardian AC9200WCA is one of the most underrated air cleaners for dust and allergies that are not outrageously expensive. The 100+ filter replacement cost is another story. However, you will have to replace everything on time except the ionizer and pre-filter. Other drawbacks include the slightly larger size, the lack of air quality indicator, and Auto mode in the specification. The pros outrank the cons, and there is no doubt on AC9200WCA dust filtration capability. If you want an air cleaner with a proven track record and large pre-filter, look no further.

In short: The perfect machine to counter a dusty home. Come with 5-stage filtration that pair well with the strong airflow delivery rate and CADR. ⚠️ Buy this if you want a mid-range dust air purifier with comprehensive filtration, UV light, and ionizer.

Your best dust removal partner for everyday vacuuming without the exuberant cost. Even though Coway AP-1512HH Mighty CADR might be miles behind Coway Airmega 300, rest assured, it is still a very practical and usable dust catcher. The boxy 16.8 x 18.3 x 9.6 inches size is considerably small and lightweight for a console air cleaner. Still, we would not recommend placing it on the table. Upfront, a circular clean panel design adds aesthetic without affecting the air inlets flow. Unlike most models that slap an AQI at the front, Coway smart air quality indicator is located at the top with a real-time update (Blue = clean, Purple = Medium, Red = Highly polluted). Overall, the build quality is solid and tough, even though it is made entirely of plastic. The default 3 years warranty is well-received for home appliances at this price point.

An affordable yet powerful 4-stage HEPA air purifier that can deal with a dusty room. A newer version is available with incremental improvements.

At a very decent 200+ price, you get all the bells and whistles that are typically reserved exclusively for a premium dust air purifier. First, you have two separate HEPA and Odor filter replacement indicators to let you know which filter is dirty worn out. The 1, 4, 8 hours timer can be set to turn off the device after the selected time frame. Besides the standard 3 speeds, you also have an auto mode that keeps the fan speed low and only activates higher speed when there is an increase of dust pollutants in the air. With or without autonomous mode, the 3 fan speed will output a quiet 24.4 dbA at the lowest speed and an audible 53.8 dBA at the highest speed. Coway AP-1512HH Mighty will run quietly in the background without disturbing your daily routine, including bedtime. As an Energy Star Rated model, power output is low between a mere 4.9 to 77.8 watts. You can leave it running all day while you're vacuuming to capture stirred dust before it settles to the ground or any surface area. There is also Eco mode that saves energy by stopping the fan when there are no heavy pollutants detected for 30 minutes.

Going into Coway Mighty specification:

  • Dust free CADR - 246 cfm
  • Room Coverage - 326 sq. ft.
  • Fan Speed - 3 with Auto Mode
  • Air Filtration - Pre-filter, True HEPA filter, Deodorization filter, Vital Ionizer
  • Warranty - 3 years

Coway AP-1512HH Mighty comes with a proven 4-stage HEPA filtration that guarantees you'll have fewer irritants to worry about. The highlight permanent pre-filter traps specks of dust and any allergens that travel along. The pre-filter is durable, washable, and reusable thus, trapped debris, dust mites, hair, dander can be easily washed away with lukewarm water. Following that is the True HEPA filter that traps 99.97% of microscopic particles down to 0.3 microns like mold, mildew, pollen, and germs. For chemical fumes, tobacco smokes, cooking, and pet odors, you have a deodorization filter standing by. Finally, the vital ionizer will pull contaminants down for the filter to capture by diffusing negative ions attached to positive ions particles. The ionizing method is safe and natural and does not generate any harmful ozone like others believe. You can leave the ionizer on even if a person is hypersensitive to dust allergens.

To complement the purification, Coway Mighty's decent clean air delivery rate comes with dust-free CADR at 246 cfm, pollen-free at 240 cfm, and smoke-free at 233 cfm. Close to Coway Airmega 300 output despite costing about 3 times less. Purifying coverage is not too shabby either at 326 square feet of space. Highly suited for a bedroom, baby room, basement, garage, or living room, depending on which place is the dustiest.

A great all-around dust air purifier that will fit into most people's budgets, there are very few faults in this wonderful machine. It is cheap to own with a low filter recurring cost of fewer than 50 dollars. If we are trying to be on the picky side, Coway Mighty has been in the market for quite some time with certain design elements that feel dated. The particle sensor is less responsive to nearby dust when compared with other premium models. The short 6 months carbon filter lifespan can also be a hassle to change. If you want to breathe in less dust and live healthier without bearing high filter costs, Coway AP-1512HH might just do it.

In short: An affordable yet powerful 4-stage HEPA air purifier that can deal with a dusty room. A newer version is available with incremental improvements. ⚠️ Buy this if you want a cheaper version of Coway Airmega without losing much on the air performance.

What Is Dust Allergy?

Dust allergy is an allergic reaction that causes sneezing, runny nose, wheezing, itchiness, and watery eyes when inhaled. It is the main cause of all-year-round allergic rhinitis. A common indoor allergy is associated with dust mites, a tiny bug (less than one millimeter) that live in house dust. We are allergic to body parts and feces of dust mites rather than the bug itself. Preventive measures and treatments from medication, allergy shots, and vacuuming. An air purifier is one of the proven and safest ways to alleviate dust allergies.

Where To Place An Air Purifier For Dust Removal?

You should place an air purifier in the dustiest room or where you spend the most time. Typically it will be in the bedroom due to the limited space and dirty vent. Just make sure to leave 1-2 feet of space between the wall and leave the air cleaner on 24x7 as there are neverending dust particles in the air. Runtime is critical in determining the efficiency of air cleaning. It takes hours for an air purifier to clean the room and the dust particles will gradually buildup when it's off.

What Is House Dust Made Of?

Domestic dust, AKA house dust, is not just made of grey dirt and human skin cells that settle on surfaces. It comprises various bits of accumulated tiny particles in the house such as:

  • Soil/ debris
  • Outdoor particulate matters
  • Organic matter
  • Mold, mildew, pollen
  • Cigarette smoke remains
  • Dead skin
  • Hair, pet hair
  • Textile/ Paper fibers
  • Pet dander
  • Dust mites
  • Food particles
  • Insects feces

The type of dust produced indoors is highly dependent on the location, outdoor environment, number of people living in the house, and exposure. For example, a house with cats has dust that contains cat hair and dander, while a house located close to nature has more pollen dust than an urban area. Still, around two-thirds of dust contains outdoor pollutants such as dirt, pollen, and soot.

Why Does My Bedroom Get So Dusty?

Loose fibers and poor ventilation is the main reason for a dusty bedroom. Most bedrooms are small yet occupied by a bed, drawer, and wardrobes. The lack of room space means dust will easily pile up on top of a cabinet surface, shelf, garments, and underneath a bedframe. Dirty air conditioners and heating systems with clogged filters are also contributors. Clothes, towels, undergarments, books all contain fibers that will break down from eventual wear and tear to create a speck of dust. Adding skin flakes and hair follicles that naturally fall from our bodies, these dust particles will become dormant, settled on the ground, and stirred back in the air when disturbed.

How Air Purifiers Can Help Reduce Dust?

An air purifier will circulate clean air by reducing airborne dust before it settles on a surface. Dust and other particulate matter will be drawn into the filtration through the internal fan. The multiple filters, e.g., pre-filter, HEPA filter, will capture the pass-through contaminants and release purified air back to the room. The cleaning cycle will continue until you turn off the air purifier. You will feel gradual improvement in the home air quality, breathe better, and experience fewer allergy symptoms.

Do Air Purifiers Get Rid of Dust Mites?

An air purifier will effectively remove airborne dust mites and their food sources e.g. dead skin cells, dander. Dust mites are microscopic creatures related to spiders. They thrive in warm, humid weather and feed on dead skin flakes. Even though dust mites don't bite, they can cause skin rashes, trigger dust mite allergies and asthma. Once the bugs have settled in the bed, pillow, mattresses, or upholstery, there is nothing an air cleaner can do.

How To Reduce Dust In House

Dusty home can irritate and create an unhealthy environment for the occupants. Dust pile up quickly in hard-to-reach places like top-shelves, fan blades, and gaps at the back of a cabinet. While an air cleaner can make a big difference, you will still need to do house chores to reduce the overall exposure. Here are some easy dust reduction tips that you can start practicing.

  • Get more than one air purifier – If you have dust problems in multiple rooms or different floors, you will need at least 1 air cleaner for each room. That way, clean air can distribute evenly across the house.
  • Clean air filter - You will be surprised how fast dust will spread in the air with a dirty filter. Filters in ventilation, HVAC, air conditioner, and air cleaner require cleaning regularly. Check the manual on the filter's periodic maintenance.
  • Vacuum daily - Preferably with a HEPA vacuum cleaner. Vacuum thoroughly at every cover of the room, including hard-to-reach places and carpet. That's where dust bunnies are born.
  • Change your bedding regularly – Especially if you wake up with a nasty rash or itches. Change your bed sheet, mattress, pillows case every 1 to 2 weeks to kill off dust mites and remove loose fiber. Consider switching to hypoallergenic covers for better dust mites protection.
  • Organized your home clutter – Keep the closet door closed at all times. Hide garments, clothes, and towels inside a drawer or cabinet to avoid dust accumulation. Store toys, books, gadgets in a box or plastic container rather than exposing them.
  • No indoor pets if possible - Dogs and cats will also contribute to dust through shed hair, pet dander, ticks, and dirt. If the furry one must stay, groom them daily.
  • Avoid carpet and faux – A dust mite magnet as carpet is one of the dirtiest items in a household. Vacuum it daily or wash it in a washing machine when possible. You can also bring it outside for beating by draping it on a ledge or gate. That way, all the dust particles will be released outside, far away from your home.
  • Never use feather duster - It might seem effective, but feather dust just moves dust from one place to another. Use a damp cloth or rag that is electrostatically more adhered to dust. Always wipe from top to bottom.
