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 though 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 as it can help people suffering from allergies or asthma to breathe better. No compromisation on quality whatsoever.
Room size/ Coverage Dust can be found on every corner of the room. A HEPA air cleaner uses filters and fans to remove dust and circulate clean air. Our room size measurement is based on the number of air changes released hourly by the air purifier. The higher the number of air changes, 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.

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 CADR in all residential air cleaners verified by AHAM. The official Dust-free CADR is at 950 cfm, followed by Pollen free 900 cfm, and 800 cfm for smoke. That's 4 times the clean air output of a Winix air purifier that is featured here. Tally with that is the excellent airflow distribution and 1180 square feet purifying coverage powered by 3 German-engineered fans. You can expect a subtle noise level from 32 to 58 dB(A) but energy usage can be high with up to 256 watts per hour. Blueair Pro XL is ideal for large room-size e.g. offices, living hall, and kitchen but not so much on the bedroom (overqualified).

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

Blueair Pro XL powerful 990 cfm airflow delivery rate can cover a massive 1180 square feet of room space. The Trio encapsulated particle-charging chamber ionizer will electrostatically charge particles like dust mites, pollen, pet dander, mold spore that are drawn into the filtration. This allows the trio Blueair Pro3 Particle Filter to swiftly remove 99.97% of irritants as small as 0.1 microns. For smoke particles, you have the trio Pro SmokeStop filter that can adsorb any chemical fumes and odors including radon, ammonia, CO, CO2, VOCs, and ozone. On top of it all, 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 from escaping.

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 you can find. It is also the only model in the pro series that comes with the Air Intelligence Module. With it, the auto mode can be enabled that automatically adjusts the fan speed accordingly when there is a high level of pollutants detected.

Blueair Pro XL is not without some drawbacks though. 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 from room to room. There is also an expensive price tag and high recurring filter cost to contend with. For the price you paid, there is no Wi-Fi pairing, remote control, and timer. Unless you are staying close to an industrial area or have a severe dust allergy, opt for the smaller Blueair Pro L or Pro M. 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 that is very easy to operate. No other air cleaner can match the strong airflow with crazy high dust CADR (950 cfm!).

You also have an auto mode that will keep the fan speed at low and activate higher speed when there is an increase of 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 Mighty will run quietly in the background without disturbing your daily routine. 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 to help capture airborne dust before it settles to the ground. Eco mode will save energy by stopping the fan when there are no 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

Standard but proven 4-stage HEPA filtration guarantee you'll have fewer irritants to worry about. The permanent pre-filter can capture speck of dust and any allergens that travel along. It is also washable and reusable thus trapped debris, dust mites, hair, dander can be easily washed away. Following that is the True HEPA filter that can trap 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 that can remove the smoke particles. Finally, the vital ionizer will pull contaminants down by diffusing negative ions that attach to positive ions particles. It is a safe and natural ionizing method that does not generate any harmful ozone.

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. Purifying coverage is not too shabby either at 326 square feet of space. Highly suitable 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's very little fault in this wonderful machine. For an air cleaner that can help reduce dust in your home, it is considerably small and lightweight. It is also cheap to own (less than $150) with little recurring filter cost at less than 50 dollars. On the picky side, Coway Mighty is in the market for quite some time with certain elements that feel dated. There is also the short 6 months carbon filter lifespan that can be more of a hassle than a performance issue. If you want to breathe in less dust, live healthier without bearing high electricity bills, Coway Mighty is the perfect answer.

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.

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 well-made, modernly designed air purifier with a front real-time air quality indicator. The dotted circle indicator will change 4 different colors according to surrounding air quality (good, moderate, unhealthy, and very unhealthy). A 5 years warranty also comes standard in the package on manufacturing defects and non-wearable parts.

Being an Energy-star rated model, Coway Airmega 300 only consumes 6 watts of energy at the lowest speed. That is even lower than most portable air cleaners despite the strong airflow output. The noise level is also Airmega 300 strong suit between 22 to 52 decibels. You can run it quietly in the bedroom when you are trying to get some rest after a long day. It is also not overly bulky given the 13.6 x 21.2 x 13.6 in body size and 21.4 lb weight. We would appreciate built-in casters like in IQAir but as long as you are not moving it around it's fine.

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 2 permanent pre-filter with one on each side of the air inlet. With endless dust particles in the air, the pre-filter is designed to be washable and reusable for many years to come. The well-protected Max2 HEPA can focus on trapping dust allergens as small as 0.3 microns with 99.97% efficiency. Finally, the activated carbon filter will remove chemical smoke and odors that cannot be captured by the HEPA filter. 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. CADR is equally impressive at 260 cfm benchmark. Great for all spaces e.g. living hall, office, bedroom, or an entire floor with doors wide open.

Airmega 300 has many other practical features that can enhance the usability of the air cleaner. You can easily set 1, 4, or 8 hours of interval time when to stop the air cleaner from operating via the control panel. Auto mode will automatically adjust the fan speed according to surrounding air quality. Sleep mode will lower the light intensity and lock that fan speed to low. A separate Pre-filter and MAX2 filter lifetime indicator that reminds you when to clean or replace the filter. There is even a dedicated light button that can disable the front indicator light.

Airmega 300 is far from cheap. All the awesome features we mentioned do incur an extra cost, especially in the filter department. You are looking at around 100 dollars annually with 12 hours of daily runtime. If you just want a simple air cleaning device, there are other cheaper dust air purifiers in this list with good discount.

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

Winix 5500-2 is a great dust remover at a fraction of the cost. The black housing that fits nicely in most home decor and well complimented by the front air quality indicator. The AQ indicator color will change from blue with good air quality, to yellow, and red when air quality is bad. The Air inlet is located at the sides with a top air outlet hidden behind the back. A typical console air purifier setup.

While Winix 5500-2 is on the cheaper price end, it comes with a good 360 square feet coverage that can support a larger bedroom, living room, nursery room, or even a dusty storeroom. The same goes for the decent 226 cfm airflow performance and dust CADR at 243 cfm, pollen at 246 cfm, smoke at 232 cfm. Noise level is reasonably quiet at 26.6 to 60+ decibels with power usage between 5 to a max of 90 watts. At turbo speed, the multi-stage filtration will quickly alleviate dust allergic reactions particularly sneezing and runny nose. If you are planning to leave it running throughout the night, we recommended leaving Winix 5500-2 in turbo speed for a couple of hours and only set to auto/ sleep mode before you hit the sack.

Moving to usability, Winix 5500-2 is very easy to use and comes bundled with remote control. 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 set higher speed when an increase of pollutants is detected. Sleep mode works very well thanks to the VOC and light sensors that activate automatically when there is no light source. Timer is very useful to set when you're away for work or about to sleep. The filter indicator reminds you to change the filter when it is 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 permanent pre-filter that 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 would adsorb indoor smoke and odors coming from cigarettes, cooking, pet, and even body odor. Optional PlasmaWave technology produces Hydroxyls to help break down allergens, germs, and odors for the filter to capture. 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 con that we could think of. 5500-2 air purifier that is not so "affordable" in the filter department. Like most Winix models, the filter replacement set can be a hassle in the long-run at around 80 dollars annually. Thankfully the pre-filter is washable so you do not have to replace that. If money is an issue, consider the cost-effective option 5300-2 if you don't mind dropping a few features. The shorter 2 years warranty period could also do with a bit of boost. Winix 5500-2 also not the most silent air purifier out there, but given its size and dust removal capability, we have no issue recommending one.

In short: One of the best dust air purifiers that cost 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.

At maximum speed, energy usage is at a high 100 watts with a noise level exceeded 62 decibels. However, it has some cons along with pros. First, the expensive selling price is the big stumble block for this unit. The filtration set is also non-washable so you will have to fork out up to 460 dollars depending on the hours of operation and how clean is the air. The lack of autonomous support like Auto mode, Sleep mode, AQ sensor is also a big bumper. You will need to purchase Blueair Aware monitor to get some of the features mentioned. At the end of the day, Blueair 605 can reduce dust build-up in the house thus less vacuuming is needed. 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.

Here is a non-dust related fun fact. Medify MA-40 is a Florida based and woman founded company. More importantly, it is a prominent dust air purifier that does not produce any harmful byproducts. The practical and large horizontal air inlet design help forms the tall 22 inches height body. At 15.6 pounds in total weight, it is bulky but not overly so. You can still move it around with relative ease when needed to. While there are many other smaller air cleaners to cherry pick from, non comes with MA-40 dust caliber including a medical-grade HEPA filter.

We are a big fan of the tempered glass panel and Medify MA-40 does not disappoint. It comes with a 4 preset timer, a filter replacement indicator, a child lock that locks the control, and 3 fan speeds. Fitting is on par with all the top-tier models with no misalignment and off-gassing. The standard lifetime warranty from the manufacturer is a good testament to its build quality.

Noise level is not Medify MA-40 strong suit. It is at a rather steep 46 dBA "sleep mode" while noise could go as high as 66 dBA. You could still use it in the bedroom to remove dust as long as it is placed further away from the bedroom. Being an Energy Star Rated model, power usage is only at 54 watts per hour. You can efficiently and effectively leave it running 24x7 to capture dust.

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. The dual intake pre-filter traps large particles like dust mites, hair, fibers, and lint from passing through. Next, the H13 HEPA filter removes 99.9% of irritants as small as 0.1 microns. Being the top-graded H13 HEPA filter, it 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. Lastly, there is an optional ionizer that diffuses negative ions and latches on positive ions irritants in the air. The combined particles will drop allowing Medify Air MA-40 to capture the pollutants into its filtration.

Medify MA-40 can swiftly take dust out of the air thanks to its comprehensive purifying coverage and strong airflow distribution. Suitable for large room sizes, anticipate a max of 840 square feet coverage in 30 minutes. To up the air changes to 4 or every 15 minutes, the air cleaning will drop to a healthy 420 square feet. Most people will run Medify MA-40 in the bedroom, living hall, or basement where dust will build up quickly. Common areas like the kitchen or garage will be fine as well.

Medify MA-40 CADR is 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 (higher is better).

Medify MA-40 air purifier is not without its fault either. For the price you paid, there is no AQ indicator, particle sensor to support autonomous mode. 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 where some models only have to change it every year. Not a big deal for some but it's worth taking note.

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

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 and a common indoor allergy 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. There are preventive measures and treatments from medication, allergy shots, to 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 very important in determining the efficiency of air cleaning. It takes at least a few 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 indoor highly dependent on the location, outdoor environment, number of people living in the house, and the 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 one of the 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. Through the internal fan, dust and other particulate matter will be drawn into the filtration. 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 the spider. They thrive in warm, humid weather and feed on flakes of dead skin. 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 cause irritation and creates 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 intermittent 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 loosen 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 leaving them exposed.
  • 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 adhere to dust. Always wipe from top to bottom.

How to Choose the Best Air Purifier for Dust

Is always good to have an air purifier running in the background when you are cleaning the house. An air purifier can capture dust that stirs back up in the air and right before it settled on the couch, shelves, bed, wall, floor. However, some model requires greater effort in removing particulate matters due to its limited capacity. Instead of spending countless hours comparing models that suit your needs, here are the key features to look for when buying the best air cleaner for dust.

  • Filtration stage - To be 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. 2-in-1 pre-filter is not washable and reusable.
  • True HEPA filter - A government standard filter that captures 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 or when necessary.
  • HEPA-type filter - A lower grade version to True HEPA filter. HEPA-type filter captures 99% of the microscopic particles as small as 2 microns. Typically, you will find 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.
  • 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.
  • Ionizer - AKA ionic filter or negative ion generator. By dispersing millions of negative ions into the air, the (-) ions will merge with (+) positive ions particles. The combined ions will then drop due to the increased weight allowing the filter or plate to collect the irritants. Take note that ionizer is not an ozone generator despite some manufacturers would attempt to market 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 the filtration, the quicker clean air can be achieved.
  • Cost of ownership - A good dust air purifier will cost you min 150 and above. 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. There will be a recurring cost from 100 dollars onwards depending on the filter grade.
  • Dimension - Knowing where you want to place the air cleaning device can help you make the purchasing decision. If you plan to use it in a bedroom or a small studio, a smaller but less powerful model will be the better option.
  • Noise level - The more powerful the air purifier, the more noise the motor fan will be generated. 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 that has the lowest noise output. The availability of sleep mode is a good gauge of how silent a dust air purifier can go.
  • Power consumption - Most 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 model that is Energy Star rated.
  • 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.
  • Sleep mode - Relies on the light sensor for auto-activation. It will dim the indicator light and lock the fan speed to the lowest for minimal fan noise.
