Portable room air purifiers are designed to filter the air in a single room. They’re separate from whole-house air purifier systems and air filters, which are integrated into a home’s heating, ventilating, and air conditioning system and designed to clean the air in the entire house.

Think of a room air purifier as a supplemental unit, like a space heater in the context of a whole-house heating system, explains Misha Kollontai, who oversees testing of air purifiers at Consumer Reports. While your house might feel sufficiently warm, you might have a particularly drafty room with old, poorly sealed windows; placing a space heater there would make the room more comfortable. Similarly, he says, "a whole-house system will work at filtering all the air that passes through it via the HVAC system. But if you’re sitting next to a fireplace in the living room for extended periods of time, a room air purifier there may not be a bad idea." A room air purifier may be worth it too, say, in a bedroom, if you sleep with your pet.
Different air purifiers work using a range of technologies. A few are helpful. Others are ineffective, or even potentially harmful to your health.
Mechanical filters: These purifiers use fans to force air through a dense web of fine fibers that trap particles. Filters with very fine mesh are called HEPA filters. While they work on microscopic particles, they can also remove larger particles (including dust, pollen, and some mold spores) when they’re suspended in the air. (Some filters are labeled “HEPA-type” or “HEPA-like”—these have not been certified to meet the requirements of a true HEPA filter but may still perform adequately in our tests.) Mechanical filters don’t help with gases or odors. And they can be expensive to maintain. Mechanical filters need to be replaced every six to 12 months; they can cost upward of $200 per filter but typically cost no more than $80.
Activated carbon filters: Unlike mechanical filters, these filters use activated carbon to capture certain types of gases, including some odor-causing molecules. But they’re not particularly effective against formaldehyde, ammonia, or nitrogen oxide. Because activated carbon filters don’t combat particles, many air purifiers will have both an activated carbon filter and a mechanical filter. Activated carbon filters get saturated faster than mechanical filters, though, and require replacement more frequently—every three months, as opposed to every six to 12 months for mechanical filters. Make sure to budget for replacements accordingly: Activated carbon filters usually cost up to $50 each.
Ozone generators: These machines produce ozone, a molecule that can react with certain pollutants to alter their chemical composition. This can result in dangerous indoor air quality, and CR does not recommend these types of air purifiers. Makers of ozone generators often claim that the devices emit safe levels of ozone, but in the past, our tests found that even at low settings, some ozone generators quickly exceeded the Food and Drug Administration’s limit of 0.05 parts per million for medical devices. Plus, studies reviewed by the EPA have shown that low levels of ozone—the chief ingredient of smog—don’t effectively destroy indoor pollutants. Research also shows that ozone has been linked to decreased lung function and increased risks of throat irritation, coughing, chest pain, and lung tissue inflammation. Ozone exposure might also worsen asthma, emphysema, and bronchitis.
Electrostatic precipitators and ionizers: In these electronic models, particles in the air become charged so that they stick—magnet-like—to plates on the machine or to nearby surfaces. CR doesn’t typically test electronic air purifiers nor recommend them because they can produce ozone.
Ultraviolet germicidal irradiation (UVGI): Some manufacturers claim that their air purifiers kill airborne viruses, bacteria, and fungal spores with UV lamps. But they might miss certain bacteria and mold spores that are resistant to UV radiation. To work, the UV light must be powerful enough and the exposure must last long enough—minutes to hours, rather than the few seconds typical of most UVGI air purifiers—to be effective. CR does not test UVGI technology, though some mechanical air purifiers we test may have the added function.
Photocatalytic oxidation (PCO): Some air purifiers use ultraviolet radiation and a photocatalyst, such as titanium dioxide, to produce hydroxyl radicals that oxidize gaseous pollutants. Depending on the pollutant, this reaction can generate harmful byproducts, such as ozone, formaldehyde, nitrogen dioxide, and carbon monoxide. CR does not currently test air purifiers with PCO technology. There have been few field investigations exploring the effectiveness of PCO air purifiers, but one laboratory study, conducted by researchers at Syracuse University in New York, reported that the devices did not effectively remove any of the VOCs typically found in indoor air.
Photoelectrochemical oxidation (PECO): This variant of PCO emerged in from the manufacturer Molekule. The Molekule Air purifier did not score well in our tests for dust, smoke, and pollen removal. Since then we’ve also tested the more expensive Molekule Air Pro, which performed better at removing contaminants on its highest setting but did not impress in CR’s other air-purifier test categories, nor did it rate well in our CR member survey.
To see how well these machines clean the air, we inject smoke and dust into a sealed chamber and use a particle counter to measure the change in air particle concentration in the room as the test model runs for 15 minutes.
We test using particles as small as 0.1 micrometer and up to 1 micrometer, a range that includes dust mite allergens, cat allergens, smog, smoke, and atmospheric dust. We don’t measure for particles larger than 1 micrometer, such as pollen, because any air purifier that scores well in our tests should also be able to handle larger airborne particles.
Because most air purifiers have several speed settings, we test for dust and smoke removal both on the highest speed and at a lower speed that runs at a noise level no louder than 50 decibels. We also measure noise levels at every speed setting that a machine has. And because air purifiers must be running at all hours to be effective, we calculate annual operating costs, which include filter replacements and energy use to run the machine 24 hours a day for an entire year.
Owner satisfaction and reliability ratings are also included in a model’s Overall Score. These ratings are based on Consumer Reports’ Summer Survey of 8,377 air purifiers purchased between and . The very best models in our tests effectively sanitize the air of dust, smoke, and pollen, and receive high marks for predicted reliability and owner satisfaction.
CR recommends more than three dozen models in our air purifier ratings, and most use a HEPA filter; a vast majority also have carbon filters to help assist in the removal of odors. These models meet Consumer Reports’ criteria for safety, performance, value, and reliability. For more information, read our article on the best and worst air purifiers of the year.
Cost of replacement filters: As a general rule, you should replace filters (or clean those that can be vacuumed) every six to 12 months if they are pleated and every three months for activated carbon filters. Most of the units we test have an indicator light that lets you know when to change (or clean) the filter. The costs of filters vary widely: In our tests of large air purifiers, they range from $20 to more than $200. Filters with odor-removing carbon can cost as much as $50.
Clear Air Delivery Rate (CADR): This value is provided by air purifiers tested by the Association of Home Appliance Manufacturers. Many air purifiers have undergone AHAM’s voluntary certification program, which provides room size guidelines along with the CADR on its AHAM Verifide seal. The CADR reflects, in cubic feet per minute, the volume of clean air that an air purifier produces on its highest speed setting. For example, a purifier with a CADR of 250 for dust particles reduces particle levels of dust to the same concentration that would be achieved by adding 250 cubic feet of clean air each minute. The higher the CADR, the faster and more efficient the air purifier is. Room air purifiers with HEPA filters often achieve the highest CADR. There are different CADR ratings for removing tobacco smoke, dust, and pollen. Focus on the CADR for your main pollutant of concern. For instance, if you live with a smoker, choose an air purifier that has a high CADR for tobacco smoke.
Energy Star certification: Air purifiers must run around the clock to be effective, so you should factor in the energy cost when you shop. Energy Star certified purifiers are 40 percent more energy-efficient than standard models.
Room size: If an air purifier has an AHAM Verifide seal, you can trust that the unit can handle the suggested room size listed on the seal. Be wary about manufacturers’ claims, though. We have tested many air purifiers that are not suitable for their claimed room sizes. You can check our ratings to see what room-size range we suggest for each model based on our test results. Also, consider sizing up: Most models suitable for large rooms (350 square feet and larger) can also work well for smaller rooms at lower speeds. Lower speeds tend to be quieter—which is nice for when you’re watching TV or sleeping.
Noise: Judge an air purifier not just by how well it performs but also by how well you’ll be able to live with it. Because these machines should always be running, ideally they should also be quiet. (For reference, a noise rating around 50 decibels is roughly equal to the hum of a refrigerator.) You may be able to find a model’s decibel levels on its packaging or website listing before you buy it. Or check our air purifier ratings; we rate models on noise levels at both high- and low-speed settings.
Clean or replace filters regularly. An air purifier can’t run efficiently if it has a dirty filter. Typically, you should replace filters (or clean those that can be vacuumed) every six to 12 months for pleated filters and every three months for activated carbon filters.
Place it wisely. If you have just one unit, put it in the room where you spend the most time. For most people, that’s the bedroom. (Some units can be heavy and clunky to move around, so if you want an air purifier in multiple rooms, you may want to buy a unit for each room.) Make sure to place the air purifier in a spot where nothing can obstruct airflow—away from curtains, for instance.
Adjust the speed. To avoid noise disruptions, we suggest running the unit on its high-speed setting when you’re not in the room and turning it down to low when you’re nearby. Or buy an air purifier certified for a larger area so that you can run it on a low speed and still have it work effectively.

During my formative years, I suffered horribly from airborne and pet allergies, with side effects as little as a runny nose up to itchy and swollen eyes, hives and trouble breathing. At the time, antihistamines like Claritin were only available from a prescription, so I’d just grab a Benadryl for the days it was severe and struggled not to fall asleep in math class.
I’m definitely not alone in my childhood suffering. According to the Asthma and Allergy Foundation of America (AAFA) and data from the Centers for Disease Control and Prevention (CDC), more than 100 million people in the U.S. experience some type of allergy each year, with allergies ranking as the sixth leading cause of chronic illness in the U.S. Don't forget to check out The Weather Channel's 15-day allergy forecast, especially when you're planning to be outdoors for any length of time.
The devastating fires in California have covered areas in 'hazardous' smoke, with researchers suggesting that wildfire events have eroded air quality by 50% in western states. The wildfires contributed up to 30% of particulate matter in the United States, according to the same source.
While outdoor air quality is certainly a trigger for seasonal allergies, indoor air quality is just as important when it comes to managing your breathing symptoms. In the following guide, we’re taking a deeper look into how indoor air pollution can affect you, and why air purifiers may be able to help those suffering from allergies. We also researched some of the best air purifiers on the market today and narrowed down our choices based on multiple criteria, including room size, price and functionality.
Indoor air pollution can appear in a variety of forms, from dust and mold to pet dander and smoke. Even cleaning supplies can introduce a number of different chemical compounds into the air. Indoor air pollution can cause a number of side effects, like irritation of the eyes, nose and throat, headaches, respiratory disease and even more serious illness, according to the U.S. Environmental Protection Agency (EPA).
Air purifiers, also known as portable air cleaners or air sanitizers, are designed to filter the air of a single room or area to reduce (but cannot completely eliminate) indoor air pollution.
You need to look at the “clean air delivery rate” (CADR) to determine if it's large enough for the size of the room you’ll be using it in. Portable air cleaners will get a higher CADR by using a “high-efficiency particulate air” (HEPA) filter.
CADR was established by the Association of Home Appliance Manufacturers (AHAM) to determine the effectiveness of an air cleaner. The higher the CADR, the faster the unit is filtering the air.
According to the AHAM, the CADR of your air cleaner should be equal to at least two-thirds of the room’s area, so in its example, a room with a dimension of 10x12 feet has an area of 120 square feet, and should have an air cleaner with a smoke CADR of at least 80.
There are three main types of air purifiers: Ozone-generating air cleaners, electronic air cleaners and filtering air cleaners.
HEPA filters do not remove gases from the air, but are generally accepted as the best at filtering particles (like dust or pollen). The effectiveness of a HEPA filter is tied to how tightly bound the fibers are, with ratings from MERV 12 to MERV 17, with MERV 13 considered the minimum you should be looking for according to Heathline.
To filter gases, it is suggested by the EPA that you choose a portable air cleaner with an activated carbon filter or other absorbent filter designed to remove gases.
It’s also important to note that neither the EPA nor Food and Drug Administration (FDA) recommend any particular air cleaning devices or manufacturers.
According to many sources, yes, air purifiers can help clear the air of allergens like dust, pet dander, pollen and other pollutants. Air purifiers only catch smaller particles and are usually only designed for one room, so it’s important to take other steps to keep your environment as clean as possible. Keeping your home well ventilated, clean and your HVAC filters also regularly swapped out can go a long way towards reducing your symptoms.
If you're looking to improve your indoor air quality, especially if you suffer from severe allergies or dislike cooking odors, an air purifier might be just the ticket. In the list below, we used a number of criteria, including first-hand testing, to select the best air purifier picks of . Read below for a complete breakdown of air purifier specs, including filter type, room coverage and app options.
Price: $149.99 at Amazon; $149.99 at Levoit.com
Filter Type: HEPA & Carbon | Effective Range: 219 sq. ft. (up to 1,000 sq. ft./1 hour) | CADR: 140 CFM | App: Yes
Other features:
The Levoit Core 300S has over 120,000+ ratings, 4.7-stars and is the best seller on Amazon, with over 1,000 Levoit products purchased in the past month. There are a number of different packages available, starting with just the basic purifier, different filters and the Wi-Fi-enabled purifier (which is what we’ve listed).
In Auto mode, the Core 300S will sense changes in the particle pollution and will adjust fan speeds, according to the company. In Sleep mode, the air purifier will continue to work at night but operates at a lower decibel level, which is ideal for light sleepers.
There are over 97,000 5-star ratings alone on Amazon, with the reviews glowing. One of the latest reviewers owns multiple Levoit air purifiers, claiming “The smart Wi-Fi [air purifiers] are the way to go, they cost a little more but it’s worth it for the ‘set it and forget’ feature. I’ve seen a huge improvement in air quality in my home.” They went on to mention that it’s easy to keep a regular schedule with the apps and they are all “incredibly quiet”.
Another said, “This air purifier has made a significant difference in the quality of air in my apartment. No cigarette smoke, less disgusting odors from neighbors that I share walls with. I would recommend this item.” One mentioned, “I live in an old house that often has mold problems, annoying little flies, and a constant dust problem. However, this air purifier has almost completely eliminated all of these issues, and I’ve been feeling much better with my allergies…it even keeps my room smelling pleasant.”
For pet owners, multiple reviewers mentioned it is very handy at eliminating odors, “I never seriously considered using an air purifier before, but as a cat owner, I was curious about how it could help combat the persistent smells. I’m happy to report that this device has eliminated almost all of the odors and kept my bedroom feeling clean and fresh.”
The main complaints from users were how loud it could be, concerns about the longevity of the product, and some mentioned there was a bad smell with their products and that it didn’t clean the odors air as much as they had expected.
Price: $284.99 at Amazon
Filter Type: HEPA & Carbon | Effective Range: 2,640 sq. ft./1 hour | CADR: 292-335 (up to 598) | App: No
Other features:
The Medify MA-50 Air Purifier has a powerful CADR rating when you need deep cleaning air purification power, especially during fire season. It averages a 4.4-star rating and has over 1,000 reviews on Amazon. With HEPA H13 filtration, you'll be getting some of the smallest particles trapped in this air purifier, especially when compared with other air purifiers which use lower quality filters. One of the reasons we picked the MA-50 version (rather than a smaller option like the MA-40) is that this product version came without the UV light and ionizer option, which according to some of our research may be more likely to produce ozone.
If you want to learn more, please visit our website ozone air purifier.
Most reviewers that use the Medify MA-50 Air Purifier in their home say they keep it at the lowest setting for the quietest results - once you start getting into the higher fan settings, you’ll notice it can get loud and vibrate a little. Using it at a higher fan setting for a shorter period of time, however, is recommended if you’re trying to reduce some odors in the room (especially after cooking, according to one reviewer).
As one reviewer puts it, “We have a bunch of Medify air purifiers - the small ones for rooms and big ones for bigger areas - and I wish I had this unit just a little earlier.” Another said, “This air purifier is the definition of ‘you get what y
ou pay for.’ In that I mean both the unit and the replacement filters are ridiculously expensive...but they actually work! I am simply amazed by how much better I feel when I'm in the same room as this filter.”
Some complaints were that the MA-50 unit didn’t last beyond two years, and the noise level at the higher settings is disruptive. Others felt that the replacement filters were too expensive. Also note that the CADR rating and square foot coverage is only at the highest level settings and tested with eight foot ceilings.
Price: $173.25, was $206 (white) at Amazon and $173.25, was $206.99 (black) at CowayMega.com
Filter Type: HEPA & Carbon | Effective Range: 361 sq. ft. (up to 1,748 sq. ft./1 hour) | CADR: 233-246 CFM | App: No
Other features:
With 4.7-stars and over 26,000+ ratings on Amazon, we selected the Coway Airmega AP-HH air purifier as a top pick for large rooms due to its high CADR rating, square foot effective range and multiple filtration options. Available in black and white on Amazon and CowayMega.com, this air purifier is reasonably priced (especially while on sale), and has appeared on numerous top pick lists.
When used on auto and eco mode, the air purifier fan adjusts based o
n the air quality indicators. The ionizer is a “bipolar device [that] generates an electro-chemical reaction to further reduce ultra fine particles in the air like viruses and bacteria” according to the company page. It’s suggested to clean the washable pre-filter every two weeks, change out the charcoal filter every six months and the HEPA filter once a year.
One reviewer called it an “excellent [air] purifier”, going on to say, “I notice that it is reactive to smells, smoke and other air-purity issues when they are occurring, even when I am simply cooking something in the kitchen.”
Some common complaints about this Coway air purifier included a bad smell during the first day after set up, difficulty in sourcing replacement filters, and the display lights on the unit can be disruptive to those with light sensitivity when it's in the bedroom. The other caveat we will mention is their abnormally high ozone emissions listed in the Energy Star documentation - this is one of the highest we've seen, and it's likely tied to their ionizer within the air purifier unit.
Price: $84.99, was $99.99 at Amazon
Filter Type: HEPA & Carbon | Effective Range: 225 sq. ft. (up to 1,000 sq. ft./1 hour) | CADR: ~142 CFM | App: Yes
Other features:
If you’ve decided the Levoit isn’t quite right for you, and you want to save a few bucks, take a look at the Clorox Air Purifier as a competitive alternative. This size is ideal for medium rooms and depending on the size of your ceilings it can circulate air up to 225 square feet of space five times an hour, according to the company page.
It has over 1,300 total ratings (an average of 4.6 stars), and 1,000 5-star ratings on Amazon. Most of the reviews are also very straightforward, with many saying they are happy with the overall performance, effectiveness and price of the model.
As one stated, “I am very happy with this air purifier. The reviews were good, the cost was reasonable, and it works. I have definitely noticed a reduction in stale odor as well as dust since purchasing this. It’s also extremely quiet. It’s also small enough to tuck into an unobtrusive yet functional space. My neighbor purchased two as a result of my recommendation.”
Another said, “This purifier runs silent and is perfect for a dusty environment like a work office. Practically no set up required. Just plug it in and turn it on. [The] filter can be removed and be blown out with an air hose and be reused so that you don’t need to buy expensive replacement filters like so many other models. Recommend!”
As for complaints, it was largely around the longevity of the product, the filters not lasting as
long as the company says they should, and not getting as much square footage coverage as expected. The square footage stated is based on eight-foot ceilings.
Price: $70.71 at Amazon (single); $139.99 at Blueair.com (bundle)
Filter Type: Carbon | Effective Range: 93 sq. ft. | CADR: 60 CFM | App: No
Other features:
The Blue Pure Mini Max is our pick if you’re looking for an air purifier for a small room on a decently low budget. If you have a small bedroom or office, this could be all the air purifying power you really need.
One of my colleagues has multiple sizes of the Blueair purifiers, and said “I’ve noticed a significant change in the air quality of my home. The air is cleaner, less allergens - and even my pets are sneezing less. There are three settings, so if you like white noise you can set it louder, while I prefer it to be quiet. The light sensor that lets you know when the filter needs to be cleaned is also very handy.”
There are no air sensors, app or smart assistant options like the Levoit, but if you don’t need any of those extra features, why pay for it? The other Blueair models, like the 411 Max, also have high reviews with a few extra bells and whistles if you don’t mind paying a little more. No matter the model, though, you should plan to replace the filter every 6 months.
Many of the reviews are pleased with how quiet the Blueair products are, with one saying, “We have been users of Blue Air filters for years…We have noticed an improvement in the amount of dust and the air quality in our home.” Another one said, “It is extremely quiet and I noticed a difference in air quality in record time. I suffer [from] allergies this time of year and having this device in my office has been a game changer!”
However, other reviewers complained about a plastic smell from their air purifier and slow customer service times. Some of the Blueair products have been reported to have some ozone emissions though the company does claim its within safe limits.
Price: $260, was $329.99 at Amazon (HP201); $279.99 at SharkClean.com (HP202)
Filter Type: HEPA & Carbon | Effective Range: 256 sq. ft. (up to 1,000 sq. ft / 1 hour) | CADR: ~165 CFM | App: No
Other features:
I've tested a number of Shark products over the past few years, and have been a long-time fan of their variety of high-performing vacuums, robot vacuums and mops, grills and more. This Shark HP201 Clean Sense Air Purifier Max claims to clean up to 1,000 square foot rooms in up to one hour, and is ideal for targeting common allergens like dust, dander and smoke. This air cleaner has a proprietary filter that the company claims to exceed normal HEPA standards, and it's most ideal to use in bedrooms, living rooms, dining rooms and even basements.
The HP201 model currently has 4.5-stars and over 1,400 ratings on Amazon, while the HP202 model on SharkClean.com has 4.7-stars and 200 reviews. As one reviewer said, "My daughter has allergies and we have two cats. This cleaned up the air in a large room. [It] was so quick and easy to set up and turn on. Iti s super quiet, which I love." Another said, "We have two dogs who are over 100 pounds and have long hair. They bring in all kinds of dust, dirt and dander...we got this for the bedroom. I noticed a sudden decrease in dust in our bedroom. I also like the white noise it provides."
Our Testing: I've been testing out this air purifier against some of the other leading brands, and just this past week we've been using a lot of oils while cooking, as well as repeated use of our gas oven, and the air purifier immediately goes into overdrive to help combat the fumes and the smoky haze. When cooking, the air sensor dropped to 80-84%, and whirled to life. After finishing and eating, the air purifier was already making a sizeable dent in the air quality, and within about 10 minutes after we bumped it up to full fan speed, it had cleared the air back to 100% air quality.
For complaints, some reviewers didn't really like the auto features, as it would kick on even when displaying good air quality -- many of the low reviews felt the air quality sensor wasn't reliable, and the replacement filters are expensive. The other issue recorded has been a sudden drop in air quality reading to 0%, which has the air purifier continually running with no clear way to fix the issue, and customer service hard to reach.
Shop It: Amazon, PuroAir.com
Best Price: $159.99, was $199.99 at Amazon; $279 (two-pack) at Amazon
Filter Type: HEPA & Carbon | Effective Range: 284 sq. ft. (Up to 1,115 sq ft./1 hr) | CADR: 181-204 (Dust - Pollen) | App: No
ther features:
“Wow,” says one reviewer, who ended up purchasing the PuroAir 240 after their children were experiencing some health issues. Allergy and asthma sufferers know that pollen and dander are some of the most vicious culprits of a stuffy nose, sore throat and breathing issues. We selected the PuroAir 240 as our best pick for those suffering from allergies thanks to its filtration system, HEPA and activated carbon filters, as well as its CADR rating for dust and pollen. Unlike some of the other products on this list, there is also no ozone emissions since it will not have any UV or ionizers.
“I have a true test for this gem of an air purifier: we have skunks that have burrowed under our home…so when the skunks “move in” each fall and spring it can fill the whole house with that extremely strong, awful smell.” This reviewer went on to mention after they set up the air purifiers, the skunk smell disappeared.
For complaints, some noted they really didn’t sense or smell any difference in air quality (especially those with pets), and that the air sensor was not accurate. Filter replacement prices were also not ideal, and some felt that they were not shipped brand new units. If you order this air purifier from Amazon, be sure to do a complete check within the return policy period.
I've been spending a lot of time researching various air purifiers, from performance and features, first-hand testing, positive reviews and complaints. If you didn't find exactly what you were looking for, whether it was room size, price point or safety features, be sure to check out some of our reviews and deal guides as you continue your research.
This season is going to be hot, humid and stormy according to the Weather.com summer forecasts. Stay cool - and dry - with some of these highly rated products. Not sure what portable air conditioner size you need for your garage, workspace or bedroom? We've got you covered. If you're suffering from terrible humidity in your basement or crawl spaces, we detail how to determine when, and what, dehumidifier might be right for you.
During our research on these products, we attempted to ensure that we avoided ozone and ionizer air purifiers specifically due to the guidance from the EPA. One company on our list, Blueair, has somewhat questionable documentation out there, though has claimed the product is within acceptable standards. While we recommended the Blueair Pure Mini Max because of the general quality of the performance and reviews, if budget and room sizes aren’t an issue, we might suggest upgrading to the Levoit.
One of our top picks included Blueair because of the very positive feedback and extensive use. My colleague has multiple sizes throughout the house, and highly recommended the selection. As mentioned in the review, they saw a noticeable difference in air quality after purchasing this product. We've also thoroughly tested the Shark air purifiers (multiple sizes and options) and have found it produces a noticeable air quality difference, especially after cooking. We are currently in process of a complete testing of the PuroAir air purifiers and will update this review accordingly.
When pulling together our best-selling list of air purifiers, we were looking at a few different performance criteria: multi-option filtration, CADR metrics and square footage, smart home or touchscreen features, and filter lifespan. We also visited AHAM Verifide and EnergyStar.gov to cross check performance claims when applicable.
We love a good deal, but when it comes to your health, sometimes the age-old adage “you get what you pay for” is all too true. We wanted to keep our picks below $300 while still providing valuable performance.
We let the reviewers speak for themselves when it comes to hands-on testing. We strive to highlight the pros and cons of each product based on user feedback and the feature list. If a product has few (or no) verified reviewers, or the complaints outweigh the purpose and price of the product, we won’t feature it in our lists.
