How Do We Measure?
For around 130 dollars after rebate, Fellowes AeraMax 100 is one of the best inexpensive air purifiers to purchase with many pedigrees. It is allergy and asthma-friendly certified, AHAM/ CARB approved plus independently tested to remove influenza viruses from indoor air.
The slim tower body is well-built and prevents off-gassing from happening. At a 7.3 x 27.3 x 8.5 inches and 9.9 lb weight, you can easily carry it to any room that requires air purification. Very useful for a person with asthma or hypersensitive to allergies.
Let's touch on Fellowes AeraMax 100 multi-layered PlasmaTRUE air purification:
- Filtration Type - 4-stage
- Air Filtration - True HEPA filter, Carbon filter, AeraSafe antimicrobial treatment, PlasmaTrue technology
- Noise Level - Silent
- Warranty - 3 years
- 100 sq. ft. purifying coverage - Suitable for personalized areas
At such a bargain of a price, DX5 uses top hospital-type HEPA filtration without any compromisation. Unlike a HEPA-type filter, the true HEPA filter capture 99.97% of the household pollutants as small as 0.3 microns including viral viruses, dust, pollen, mold, and pet dander. What's more, the HEPA filter comes with an antimicrobial treatment that inhibits odor-causing mold and mildew growth. Next, the standalone carbon filter will trap household fumes, cigarette smoke, and pet odors via absorption. Completing the filtration is the Fellow's own PlasmaTRUE technology. An ionizer that creates an ionized field to merge and pull airborne impurities down for the HEPA filter to capture. Surprisingly, there is no dedicated pre-filter for quick dust removal where even an economical air cleaner will have it.
Rounding up with the 100 to 200 sq. ft. area, you can practically place AeraMax 100 in any corner of the house. To get the best out of AeraMax. Most people would leave it in the bedroom as we spend the most time in there.
Replacing the True HEPA and carbon filter is easy through the side drawer filter change and you only have to do it quarterly. Filter replacement cost is around 60 dollars every 12 months depending on operational hours. Reasonable but here are other cheaper maintenance models that utilize smaller and inferior filters.
For a mid-tier model, AeraMax 100 manages to retain its useful features even at an affordable price point. The front user-friendly touch screen is a bliss to use and the digital air quality indicator will clearly display how clean the air is in the room. The filter indicator will remind you to replace the filter once it is clogged or worn out.
Another uncommon for an air purifier of this low-price segment, you have a built-in AeraSmart Sensor that is very sensitive in detecting nearby contaminants. Complimenting that is the adjustable 3 fan speed with Aera+ mode for flu season and Auto mode that automatically set higher speed when there are high air pollutants lingering. At low speed, the ultra-quiet operation helps keep the noise level down so you can run it all-night during sleep. 37 to 51 watts power consumption is low despite not Energy Star Certified and sleep mode.
Something has to give as you're paying way less than other models. The drawback for AeraMax 100 is the lack of a timer, weak airflow, and low CADR return. Dust CADR is at 65 cfm, Pollen CADR is at 75 cfm, and Smoke CADR is at 68 cfm. Great for bedroom use but probably not the best option for large spaces like the living room.
In short: Delivers fresh air at fraction of the cost compared with other premium models. Great value for your money with its top medical HEPA filtration.
- Affordable 4-stage tower HEPA air purifier (+- 130).
- True HEPA Filter with AeraSafe antimicrobial treatment.
- Standalone carbon filter.
- PlasmaTrue technology.
- AeraSmart Sensor, air quality indicator, and auto mode.
- 3 years warranty.
- Below average CADR and airflow delivery rate.
- High filter replacement cost (+- 60).
Continue with this very competitive entry-level segment, PureZone 3-in-1 is one of the best value air purifiers with 2000+ Amazon reviews. It has built its own fan base and rightly calls for a spot here. With a selling price tag of slightly above 100 after sales, it can greatly transform your indoor air making it more comfortable to breathe. A phenomenon result considering the number of emerging air cleaner brands that fail to do so.
At a mere 6.9 x 12.1 x 10.8 in dimension and 8.4 lb weight, PureZone 3-in-1 is on the smallest side for a console air purifier. The modern exterior added a touch of elegance to your home without sacrificing build quality and functionality. The air inlet is nicely tucked behind the front panel with an air outlet at the top surrounding the easy to use touch-button control. Portability is another strong suit for PureZone 3-in-1 if you intend to carry it for room to room purification.
Here is the run-through of PureZone 3-in-1 specification:
- Filtration Type - 4-stage
- Air Filtration - Pre-filter, HEPA filter, Activated Carbon Filter, UV-C Light
- Noise Level - 30 - 50 dB
- Warranty - 5 years
- 200 sq. ft. purifying coverage - For small to medium room size
What makes PureZone 3-in-1 great is the Holy Grail air filtration. The stage 1 pre-filter traps initial dust, hair, dust mites, and large particles while protecting the inner filter. The stage 2 activated carbon filter absorbs noxious chemicals like formaldehyde, benzene, and odors from pets, diapers, cooking, cigarettes. The stage 3 True HEPA filter removes 99.97% of dust mites, mold, pollen, pet dander, fungi, and other allergens in the air. The stage 4 UV-C light sanitizes bacteria and viruses before releasing clean, fresh air back to your home.
PureZone 3-in-1 does not use an economical HEPA-type filter like most small and affordable air purifiers. At max speed, the mid-range purifying radius that covers up to 200 square feet of room space. Excellent for bedroom, office, kitchen, garage, dining room, and baby room. Removing large contaminants to microscopic allergens would be a piece of cake.
PureZone 3-in-1 is not shy about features too despite the low price tag. You have 2, 4, 8 hours timer that can be set to turn off the air purifier when the time is up. Filter reset button that is used after you changed the filter. Standard 3 speed and sleep mode for silent purification during sleep. To boost the energy-efficiency, you can even turn off the optional UV-C mode to save energy costs. Finally, PureZone 3-in-1 is backed by a hassle-free 5 years warranty that mitigates any fears of the air purifier breaking down.
Few things you should take note of before purchasing one. CADR is not spectacular at 80 cfm level even though purifying coverage is decent. The all-in-one filters have a relatively short 6 months lifespan so you will have to change it more regularly. The lack of autonomous features is expected given the low price. Lastly, the brand does not have another high-range model to upgrade to. If you are planning to move up from the stable line in the near future, you're out of luck. Other than that, PureZone 3-in-1 is a worthy, entry-level air purifier for those that are new to the scene.
In short: One of the best value HEPA air purifiers with UV-C light technology. Great for people with breathing issues due to allergies or asthma.
- Affordable 3-in-1 air purifier (+- 100 after discount).
- Wide room coverage for a small air purifier.
- Genuine HEPA filter and activated carbon Filter.
- UV-C Light.
- Timer and sleep mode.
- 5 years warranty.
- Unimpressive CADR.
- No autonomous features.
- Short 6 months filter lifespan.
At around 120 bucks after slashing the price, GermGuardian AC5250PT is a 5-in-1 air purifier on a budget fitted with 5-stage filtration. Being the only tower air cleaner listed here, GermGuardian AC5250PT will take up very little of your interior space. The 6.1 x 28 x 9.5 in sleek body design and 10.5 lb weight blends well in a tight corner. You can effortlessly carry the AC5250PT to other rooms that require air cleaning.
GermGuardian AC5250PT is AHAM verified, Energy Star certified, and CARB compliant. However, the airflow capacity has to take a dip to accommodate its 28 inch digital tower form body. Official dust CADR is at 123 cfm, pollen at 128 cfm, and smoke free at 116 cfm. The higher the CADR, the faster it can filter the air. At max speed, it is suitable for people struggling with seasonal allergies or bad air quality.
Let's look into GermGuardian AC5250PT 5-in-1 UVC sanitizer purification:
- Filtration Type - 5-stage
- Air Filtration - Charcoal pre-filter, True HEPA filter, Pet Pure antimicrobial, UV-C Light
- Noise Level - Silent
- Warranty - 5 years
- 180 sq. ft. purifying coverage - Small to medium room size
There is no better filtration package you can get at this low price range. The dual charcoal pre-filter would trap large contaminants and reduce common smoke, toxic fumes, and odor. Next, the Pet Pure True HEPA filter will remove microscopic particles as small as 0.3 microns with a 99.97% capturing efficiency. The Pet Pure antimicrobial agent on the surface of the HEPA filter will inhibit odor-causing microorganisms like mold, mildew, and bacteria growth. UV-C light with Titanium Dioxide (TIO2) will eliminate (kill not trap) germs, viruses, bacteria, and VOCs for good. For comparison, a similar filtration set offered in competitors' model can easily shoot out to $200.
The ideal model to protect allergy sufferers from cough, cold, and other common allergies. GermGuardian AC5250PT can cover a modest 180 square footage of space while circulating air at 4 changes per hour. There are 5 selectable speeds that you can manually set according to the room air quality. At the lowest speed, it will run ultra-quietly in the background. An informative digital display with 8 hours programmable timer lets you set when to shut off the device. The worry-free 5 years limited manufacturer's warranty is the perfect cherry on top that covers everything except for the filters.
On the cons, the filter cost is on the higher side (around $80) as there 5 parts that require replacing. You will need to replace the filter every 6 to 8 months or the filter replacement reminder starts flashing. The built-in sensors and air quality indicators are the most obvious exclusion here. Autonomous operation is nowhere to be found but understandably under the entry-level category.
In short: One of the best value air purifiers with a 5-stage HEPA filtration plus germ-killing UV-light. You do have to fork out a little bit more money for the extra features.
- Inexpensive tower 5-stage HEPA air purifier (+- 120).
- Decent air coverage and CADR for its segment.
- 5 fan speed and programmable timer.
- True HEPA filter with Pet Pure antimicrobial.
- UV-C Light technology with TIO2 treatment.
- 5 years warranty.
- Hassle to change and costly filters (+- 80).
- Uses charcoal pre-filter instead of a carbon filter.
- Lacks built-in sensors, auto mode, and air quality indicator.
Rather than picking 5500-2 as our best cheap air purifier winner, we will go with the more economical alternative. Winix 5300-2 rightly earns this spot as it is the cheaper version without losing out on too many features. It is powered by the same advanced 4-Stage PlasmaWave Technology that can keep you safe and healthy.
The black housing exterior design looks modern and timeless without overly simplistic. Controls are at the front, with the air inlet at the sides, and the air outlet at the top. At 15 inches width, 23.6 inches height, and 8.2 inches depth, Winix 5300-2 standard console size that can be a little bulky with limited room space. With all filters installed, it is not light either at a total weight of 15.4 lb. Not easy to move it around but if you do, there is a handle slot to hold on.
For the affordable price tag, Winix 5300-2 comes with everything you need via the intuitive controls. You have the dual smart sensors that detect and measure air quality for autonomous purifying. Check filter indicator that will illuminate to remind you to replace the filter after a period of time. A timer with 1, 4, 8 interval hours, and a real time air quality indicator that changes the LED light from blue (good), orange (fair), poor (red). Winix 5300-2 is also AHAM and UL certified to meet the smoke, dust, and pollen filtration performance and safety standard requirement.
Here are Winix PlasmaWave 5300-2 key specification:
- Filtration Type - 4-stage
- Air Filtration - Pre-filter, HEPA filter, Activated Carbon Filter, PlasmaWave Technology
- Noise Level - 27.8 - 60+ dB
- Warranty - 2 years
- 360 sq. ft. purifying coverage - For medium room size
Winix 5300-2 is well-supported by the dependable 4-stage filtration with PlasmaWave technology. The first line of defense pre-filter that blocks large airborne particles from proceeding forward. The fine mesh pre-filter is also washable so it can be reused over and over again. The odor absorbing carbon filter reduces noxious gases like formaldehyde, benzene, VOCs, and odors coming from cooking, pets, tobacco smoke. The carbon filter will also help prolong the True HEPA filter lifespan. The True HEPA filter with a 99.97% efficiency in removing airborne allergens like pollen, mold spores, dust, pet dander, microbes, and smoke as small as 0.3 micrometers. PlasmaWave air cleaning technology produces hydroxyls to neutralize bacteria and viral viruses like Influenza A (H3N2). A hydroxyl group (OH) is safe to breathe as it is essentially an entity of one hydrogen atom bonded with an oxygen atom.
Adding everything into the equation, you have yourself a powerful yet inexpensive air cleaner. Winix 5300-2 can cover up to 360 square feet at 5 clean air changes per hour verified by AHAM. Ideal for all room sizes including living room, bedroom, baby changing room, basement, kitchen, and garage.
Winix 5300-2 delivers a strong and punchy 240.1 cfm airflow delivery rate. CADR is equally impressive with dust free at 243 cfm, pollen free at 246 cfm, and smoke free at 232 cfm. There is a very insignificant amount of ozone output with PlasmaWave activated. Don't worry, it is safe, neglectable, and within the ozone limitation as certified by the California Air Resources Board (CARB).
Winix 5300-2 is highly functional via the adjustable 4 fan speed. At the lowest speed, it is ultra-quiet at only 27.8 dB. Very useful during night time when you're trying to get some rest. Clear white noise can be heard on high or turbo speed (60+ dB). Most people will manually select this when they need swift air cleaning or are away for work/ trip. In most cases, we recommend leaving it in auto mode that will set the right speed in real-time based on surrounding air quality. Better yet, opt for the light automated sleep mode that will switch between auto mode when there is light presence and sleep mode when the room is darkened.
As an officially certified ENERGY STAR model, Winix 5300-2 is very cost-efficient and environment-friendly. It uses only 5 watts of electricity at the lowest speed and all the way up to 70+ watts at turbo speed. Leaving it in auto or sleep mode will ensure the air cleaner run in the most energy-efficient setting.
Moving to the negatives. The lack of remote control is a miss big considering it is available in 5500-2. For the extra filtration performance, it is rather bulky compared with other portable air purifiers. The Carbon filter requires quarterly change which can be annoying at times. The biggest concern is the high filter cost that can go up to 80 dollars annually. If you have no intention of spending so much on a filter replacement, there are other more affordable air cleaners on this list.
In short: A price-friendly air purifier powered by an advanced 4-stage PlasmaWave filtration. Great features and performance but will have to do with a costly filter set.
- Powerful yet inexpensive HEPA air purifier (+- 140).
- Extensive coverage suitable for living room.
- True-HEPA filter.
- Odor Absorbing Carbon Filter.
- PlasmaWave Technology.
- Sensors, AQ indicator, auto mode, sleep mode, timer.

Let's address the elephant in the room. Medify MA-15 excellent dual filtration setup is very costly to maintain. Expect to pay 70 to 140 dollars annually as the filters required replacing every 2500 hours or 3 to 4 months.

Usability is great with simple controls. Setup is a breeze and took less than 3 minutes. You just need to find a power outlet, plug it in and turn on the device. Give it a few hours of air cycle, you will experience much cleaner air with noticeable less dust. Other add-on features include a filter replacement indicator that reminds you to replace the filter and a standard 2 years warranty with lifetime support.

The protected True HEPA filter removes 99.97% microbes and allergens that cannot be seen through our naked eyes. This including dust mite, pet dander, pollen, mold spore, viruses, and bacteria as small as 0.3 micrometers (µm) in size. The activated carbon filter traps light smoke particles and odors from cooking, pets, cigarettes, detergents that we might not realize it is degrading our indoor air quality. Levoit LV-H132 is 100% ozone-free as it does not use ionizer or UV technology that may release small traces of measurable ozone and other harmful substances.

Energy usage is excellent too at only 28 watts with a standard power supply of AC 120V/ 60Hz. Standby power is less than 0.8 watts operating at a temperature between 14°F to 104°F. You can leave it running all day without receiving a big hit on your electric bill.
Breathing in clean air will bring many health benefits and Levoit LV-132 is a well-rounded product at this price range. At full speed, the air purifier will cover a small 129 square feet of room size suitable for children's bedroom, nightstand, kitchen, work desk, or baby changing room. Because of the entry-level price tag, you can easily afford to get multiple units for each room that needed air cleaning.
As for limitation, the small filter size and 6 months lifespan are unavoidable given its compactness. The 110 cfm CADR is not great but workable for a small area with no major indoor pollution concern. Odor removal may not be its strong suit against hazardous fumes. No air quality monitor and autonomous features included either. Then again, the low price tag and all-around purification will make up for the setbacks. Levoit LV-132 is well suited for a person that has breathing difficulty or allergies.

The antibacterial filter will inhibit captured bacteria and viruses from growing in the filter. Next, the carbon filter will eliminate common smoke and odors like cooking, cigarette, smelly pets, and diaper. For stronger toxic fumes, you have the cold catalyst filter that absorbs toxic household chemicals like formaldehyde, VOCs, benzene, ammonia, and hydrogen just to name a few.

What Can A Cheap Air Purifier Do?
You don’t have to spend a fortune on an air purifying device. "Cheap" is a very loose term that would have a whole new interpretation for different sets of people. Let it be an air purifier under 200, 100, 50, there are still a lot of things a heavily discounted model can provide than just clean air.
Breathing in clean air can alleviate seasonal allergies like viral flu, asthma, and pump more oxygen into our lungs. Oxygen can help us being energetic, lower blood pressure, reduce stress, sleep better, and strengthens our immune system. In the long-run, clean air can prevent sickness like COPD, pneumonia, bronchitis, dementia, and heart disease. The only key differences between cheap (poor quality) and price cheap are the end result. A budget air purifier can still provide exceptional value within its capacity. As a matter of fact, many of the best-selling models are typically in the entry-level segment.>
Are Cheap Air Purifiers A Waste Of Money?
An affordable air purifier won't be a waste of money as it can improve air quality by removing airborne allergens, odors, and toxic gases. With the multi-level HEPA filtration, it can prevent respiratory illnesses, slow down dust build-up, stop mold/ mildew from spreading.
In general, the pricier the air cleaner, the better the specification. That is the rule of thumb although they are a few exceptional cases. If you can extend your budget, go for a higher tier model. As an air purifier is a long term investment, make sure you choose the right model regardless of the price point.
Cheap VS Expensive Air Purifier
Pricing, room size coverage, types of filtration, performance are the differences between cheap and expensive air purifier. Starting with the pricing, most affordable air purifiers will cost $100 or less while expensive air purifiers will start from $200. For purifying coverage, most low budget air purifiers will cover a smaller room size between 60 to 350 square feet while expensive air purifying device covers a wider room space starting from 300 square feet.
A high-performance air cleaner can help capture all types of airborne allergens, smoke, and odors. There are some air purifiers that come with a single-stage filtration. Avoid those. Instead, go with multi-stage filtration that maximizes the performance and guarantee your money’s worth. A HEPA-type filter can be found in the lower-range model while a True HEPA filter is used in more premium models. As for the frequency of filter change, anticipate a shorter filter lifespan between 3 to 12 months for cheaper air purifier. Premium air cleaners filters will typically last for 12 months or higher depending on the filter quality.
Is it Safe To Purchase A Cheap Air Purifier?
All air purifiers that use mechanical filters are safe unless it is an Ozonator. An Ozonator or ozone generator produce harmful ozone that will damage our body's immune system and lung tissue cells. The safest option is to go with an ozone-free HEPA air cleaner. Via the internal motor fan, the air purifier will pull in airborne particles, trapped them on the HEPA filter, and circulate back purified air.
Do Air Purifiers Use A Lot Of Electricity?
An air purifier will increase your electricity bill by a very thin margin even if you run it every single day. On average of 12 hours daily operation, you will only see a monthly increase of $3 to $5 in electricity bills. That's only $36 to $60 dollars annually. For all-day 24 hours operation, just multiply the numbers by 2. The new monthly electricity bill will be $6-$10 or $72-120 annually. Take note that the electricity cost in the United States varies from state to state.
What To Consider When Buying A Cheap Air Purifier
Whether you have a low budget of under 50, 100, 150, or 200, the ultimate goal of an air purifier is to clean the air. Any specification or multi-stage filtration should be the drive to achieve the clean air goal. Understanding your needs can ensure you're getting the best out of an air purifier without overpaying it. Be realistic about what you can get within the budget and never compare it with the top tier models. Ready? Here are the tips on how to buy an affordable air purifier with the greatest value return.
- Selling price and filter cost - Seek a balance between cheap and cheerful. Compare the package you will get with the competitors’ model. Also, account for the replacement filter cost. Match how many years does it take for the filter price to stack up and match the retail price.
- Size and weight - Not a critical factor but it’s worth taking note if you have a very specific dimension. Most models in this segment come in a compact size therefore it will not occupy too much interior space.
- Airflow delivery rate and CADR - Clean Air Delivery Rate is the official metric to measure the purification capacity of an air cleaner. Like airflow delivery rate, it uses CFM (cubic feet per minute) to reflect on the volume of clean air. Look for an air cleaner will the highest airflow or CADR output. The higher the number, the swifter airborne contaminants will be removed.
- Room size (Coverage) - Co-relate with the airflow delivery rate. Pick a model that can purify a larger room size than the one you are about to cover. You can determine and measure the square footage of the room by multiplying the width and the length. The majority of entry-level air purifiers are catered for small room size due to the low price factor.
- Pre-filter - First-stage filtration design to capture large particles like dust and hair. Regardless if is a permanent type or carbon pre-filter, it is a must-have filter in our book.
- Filtration (HEPA, carbon) - Having a good HEPA filter whether in the form of True HEPA (99.97% efficiency/ 0.3 microns) or HEPA type (99% efficiency/ 2 microns) would make a huge difference in cleaning the air. Also a necessity in our book. a carbon deodorization filter will remove gaseous compounds and household odors.
- UV-light - Ultraviolet technology that is effective in killing bacteria and viruses by altering the genetic structure.
- Ionizer - Release millions of negative ions into the air to merge with positive ions particles. The extra weight forces the larger ions to fall for the filter to capture.
- Additional features - This includes Auto mode, AQ sensors, timer etc. Whatever features the air cleaner can fit in, we’ll take it.
- Branding reputation - The longer the warranty period, the better assurance you will have. It’s not easy to find an air cleaner that offers more than 1-year warranty at this price range, so the brand reputation plays a big role here. Do consider the service center location or details of the warranty if repair is needed.
- No to ozone production - Never purchase an ozone generator to clean the air in your home. Inhaling ozone will damage our lung tissue cells, aggravate asthma, and allergies. EPA recommends the ozone level not more than 0.08 parts per million at home. So check carefully what technology is used in the air cleaner before making the purchase.
