Deal Alert!

Don't feel like scrolling? The Winix 4-Stage True HEPA Air Purifier and Coway Airmega 160 Air Purifier are now on sale for Memorial Day.



We are more aware of the air we’re breathing than ever before. Many people have taken an interest in not just cleaning and sanitizing their homes but also making sure that they’re breathing as clean as possible. That’s the purpose of an air purifier: to remove allergens from the air. Some even claim to filter VOCs and pet hair.

“Anyone who suffers from breathing symptoms like nasal congestion or conditions such as allergies or asthma can benefit from using an air purifier,” Kara Wada, MD, an assistant clinical professor of Allergy Immunology at The Ohio State University Wexner Medical Center, tells PEOPLE.

To find out which air purifiers can truly help relieve us of our sniffling allergy symptoms, we tested 38 different air purifiers, judging each device on ease of use, value, and how effectively they cleared the air. Our testing methodology was informed by expert allergists to ensure that we found the best of the best.

Keep reading to discover the 13 best air purifiers to clean your air and help relieve your allergies, as well as what you should consider when shopping for them.

Best Overall: Levoit Core 400S Smart True HEPA Air Purifier

See at Amazon.com

See at Target.com

Star Qualities

  • Quick and easy to start with user-friendly digital display

  • Fast and effective air purification left air smelling noticeably cleaner

  • Lightweight and easy to move from room to room

  • "Quiet” and “sleep” settings are impressively quiet

Red Flags

  • One of the more expensive air purifiers on our list

Our winning air purifier was a hit among even the pickiest air-purifier connoisseurs, tested in rooms with pets and allergens. This Levoit Air Purifier was easy to set up, taking just four minutes from start to finish with clear and straightforward directions.

This medium-sized model is a good fit for a large room, with solid construction and an easy-to-read digital display on top. It’s also quite simple to remove the filter from the bottom when it’s time to change it out. We found that the airflow felt great while using the air purifier, and it was never distractingly noisy. In fact, the quiet and sleep settings were super quiet.

There are loads of features on the digital display, plus even more on the app. This model is voice-activated through Alexa, too. The app is easy to set up, and it’s user-friendly, allowing the user to set a timer and create a schedule. The machine has handles on both sides, so you can move from room to room, and it’s very lightweight considering all it can do.

As for the most important part of this product, we gave it our top ranking for effectiveness. On both the low and high settings it improved the air quality, making it cleaner than it was before our tests. We found debris on the filter (and VOCs went down in our mothball test) so we felt confident this model was doing its job.

Best for Small Spaces: Levoit Core Mini Air Purifier

See at Target.com

Star Qualities

  • One of the best values for an effective air purifier

  • Lightweight device is easy to move from room to room

  • So quiet that we could barely hear it on the lowest setting

Red Flags

  • Intended for small spaces up to 178 square feet

  • Low setting doesn’t work well compared to others we tested

Here’s a small and simple model that could be a perfect choice for someone looking to buy their first air purifier. If you’ve got a small space in mind, this is a great option. The setup took just two and a half minutes. With its minimalist design, this air purifier could fit into just about any aesthetic and into any space thanks to its lightweight stature.

The Levoit Air Purifier is extremely quiet. On the lowest setting, we could barely hear it. The highest setting was a little louder, but nothing that would be distracting. You won’t be distracted by features, either. This is a very basic model with just three different settings: low, medium, and high. As for effectiveness, in our testing, the low setting was just mediocre. On the high setting, however, the smaller Levoit model performed well within 10 minutes.

Dimensions: 6.5 x 6.5 x 10.4 inches | Weight: 2.2 lbs. | Room Size: 178 square feet

Best for Large Spaces: Clorox Large Room True HEPA Air Purifier

See at Amazon.com

See at Target.com

Star Qualities

  • Effectively cleared air after 30 minutes

  • Rated to clean air in rooms up to 1,500 square feet and is smaller and lighter-weight than most other big-room air purifiers we tried

  • One of the best values for a large-room air purifier

Red Flags

  • Doesn’t come with many high-tech features

  • Only uses one HEPA filter that didn’t catch pet hair in our tests

You may know the Clorox name for the brand’s surface cleaning products, but they’re also pros at cleaning the air. The brand’s large room air purifier noticeably improved our test room’s air quality after just 30 minutes on the lowest setting. We found it to be super easy to get started with, too.

It has four fan speeds and an auto setting, and the rounded filter sucks in debris from 360 degrees around the device. It’s rated to clear rooms with an area of up to 1,500 square feet, yet still manages to be smaller and lighter than many of the air purifiers we’ve tried.

While the Clorox unit was great at removing odor and smoke from the room, it didn’t trap any pet hair in its filter during our test, so if your main goal is to trap fur, this might not be up to par.

Dimensions: 10 x 10 x 19 inches | Weight: 12.72 lbs. | Room Size: 1,500 square feet

Best for Large Spaces, Less Expensive: Aroeve MK04 Air Purifier

See at Amazon.com

See at Aroeve.com

Star Qualities

  • Cleans rooms up to 1,095 square feet but doesn’t take up a lot of floor space

  • Color-changing display notifies you when air quality is poor, moderate, or good

Red Flags

  • Machine is cumbersome and heavy to move

Large, dusty spaces are no match for the Aroeve Air Purifiers, which are rated to help clear the air in rooms up to 1,095 square feet. This device features a color-changing display that indicates the air quality levels of any given room, too.

Though this machine is capable of filtering the air in large rooms, it doesn’t actually take up a lot of floor space itself. It's sleek and would blend into most home decor, with a design that looks like a small white box that’s not dissimilar to an oversized game console.

Making use of an H13 True HEPA Filter, this air purifier quickly passed all of our tests. It significantly improved the quality of air from hazardous to safe in two to three minutes. This device also contains a UV filter, which Aroeve claims will purify the air further.

While we wish this purifier also came with pet hair filtration, the sleek look, quiet noise levels, and quick purification for large spaces make this device a great choice for those with open-concept floor plans who don’t want to sacrifice good looks and great results.

Dimensions: 13.5 x 7.5 x 17.25 inches | Weight: 8.63 lbs. | Room Size: 1,095 square feet



The More You Know

“HEPA purifiers have most studies/data with allergens, viruses, etc., so rely on those and that technology. Also, remember some things like pollen and dust mites are too small to be filtered, so you may need to take other measures for those if you are allergic.” — Dr. Purvi Parikh, MD, who specializes in Infectious Disease Allergy and Immunology and Pediatric Allergy & Immunology at NYU Langone Health



Best Air Purifier-Humidifier Combo: Dyson Purifier Humidify+Cool Formaldehyde PH04

See at Amazon.com

See at Walmart.com

Star Qualities

  • Offers purifying and humidifying in one machine

  • Comes with high-tech digital display panel with connected app

Red Flags

  • Most expensive option on our list

  • Heavy and difficult to move when filled with water

For those who are also shopping for a humidifier, the Dyson Purifier Humidify+Cool model packs a one-two punch with both purifier and humidifier capabilities in one machine. The setup was fairly easy, though filling the water tank was not intuitive, and we had to consult the manufacturer’s video for help.

It’s heavy while filled with water and will take up space in your room — the signature Dyson loop alone stands about two feet tall, while the entire contraption hits the three-foot mark. The control panel on the front of the unit displays the power level of the purifier and the humidity percentage. When changing the filter, blinking lights guided the process, which was a little tricky but ultimately doable.

On a low setting, the noise from this machine was undetectable, and on a high setting, it sounded like a small fan at medium speed — nice and quiet for sleeping. As for features, this two-in-one combo has an oscillating feature as well as an app, so that you can connect to all of the Dyson products in your home at the same time.

The effectiveness of this model impressed us the most, clearing the air in our testing tent with impressive speed — even after running for just five minutes on high. And while we loved how effectively the unit cleared the air and the added value of a built-in humidifier, the price tag does cause some sticker shock.

Dimensions: 36.33 x 11.02 x 12.23 inches | Weight: 18 lbs. | Room Size: 400 square feet

Best for Pet Hair: Black+Decker BAPUV350 Air Purifier

See at Amazon.com

See at Wayfair.com

Star Qualities

  • Four-stage filtration effectively captured more pet hair than any other air purifier that we tested

  • Highest settings are powerful and quickly cleared the room

Red Flags

  • Highest settings are a little loud

  • Larger unit compared to some others we’ve tested

This Black and Decker was able to capture hair while it cleared the air. After turning the air purifier on its highest setting in our test room, not only did the air smell clean and crisp but there was also a noticeable amount of hair built up on the filter that the air purifier extracted from the air. That may be thanks to the four-stage filtration system which includes a HEPA filter, Ozone filter, electrostatic filter, and pre-filter.

The Black and Decker purifier also comes with a few features, including a sleep and auto mode. The unit is a little larger than some of the others that we’ve tested, and the design looks kind of like a futuristic kitchen trashcan. And, while the highest settings were super effective, they were also a little loud for our liking. This air purifier is on the mid-to-expensive end of the price range for the units we’ve tested, but for homes with pets, the hair-sucking filter makes it well worth the price.

Dimensions: 27.1 x 14.4 x 14.8 inches | Weight: 28.2 lbs. | Room Size: 500 square feet

Best with Carbon Filter: Rabbit Air BioGS 2.0 Ultra Quiet Air Purifier

See at Amazon.com

See at Curated.com

Star Qualities

  • Uses 3 different filters: pre-filter, HEPA filter, and activated carbon filter

  • Energy efficient

  • Sleek design looks more like a sculpture than an air purifier

Red Flags

  • Large and heavy

  • Only effectively removes allergens in spaces up to 275 square feet

With five solid gold stars at Amazon, this air purifier from Rabbit is Energy Star certified and (as its name implies) impressively quiet. It features three filters: one pre-filter, one charcoal-based carbon filter, and a HEPA filter to top it all off.

After about 10 minutes on its lowest setting, the Rabbit Air BioGS was able to significantly improve the air quality of our testing room. We liked that this device had easy-to-read settings and a timer for shutting off.

The unit is rather large, but the design is sleek look and sculptural, so we’d probably try to pass it off as a piece of living room art. It’s also pretty heavy, so keep in mind that this might be a difficult unit to move for those who have a harder time lifting heavy things. It’s rated to be effective for spaces up to 550 square feet for normal use or 275 square feet for heavy allergy sufferers.

Though the Rabbit Air BioGS doesn’t have a stand-alone pet hair filter, the pre-filter and HEPA filter do a pretty good job at clearing away pet hair particles, as well as pet allergens and odors. This device will be more effective in smaller spaces, but overall, we felt that this product was a great value for the cost.

Dimensions: 22.2 x 16.6 x 9.8 inches | Weight: 16.8 lbs. | Room Size: 550 square feet

Best for Living Rooms: Winix 5500-2 4-Stage True HEPA Air Purifier

See at Amazon.com

See at Target.com

Star Qualities

  • Efficiently cleans rooms up to 1,740 square feet

  • Ready to use right out of the box

  • Color-changing air quality indicators

Red Flags

  • Indicator lights didn’t pick up dirt or incense smoke accurately

Fully assembled and ready to use right out of the box, the Winix 5500-2 air purifier was as clear to use as the air that comes out of it. This device is rated to refresh the air in a space up to 1,740 square feet in an hour, which makes it a great choice for open communal spaces such as living rooms and kitchens.

One of the more unique features offered by the Winix 5500-2 is an indicator light that changes colors according to air quality — blue for “good,” orange for “fair,” and red for “poor.” This feature proved useful in our tests, and we watched the light change turn orange when we sprayed air freshener near the device, then back to blue once it had filtered out most of the scent after 30 minutes on the lowest setting. We did notice that the color-changing indicators didn’t really pick up the dirt or incense that we put in front of it during our tests, so the reading might not be as accurate as it claims to be.

Dimensions: 15 x 8.2 x 23.6 inches | Weight: 14.8 lbs. | Room Size: 1,740 square feet

Best for Bedrooms: Levoit Core 300S Smart True HEPA Air Purifier

See at Amazon.com

See at Target.com

Star Qualities

  • Sound is nearly undetectable on the lowest setting and quiet on the highest setting

  • Connected smart app monitors air quality in real-time

  • Includes sleep timer and ability to dim the display

Red Flags

  • One of the more expensive air purifiers for its small size

The filter was easy for us to locate, with an intuitive twist-off design. The device is pretty simple, with three fan settings to choose from and a sleep timer and dim-display options. The lowest setting was impressively quiet — even quieter than most household refrigerators and dishwashers. Even the high setting was quieter than the lowest setting of some purifiers we tested. The Lecoit Core 300S is also impressively powerful and easily cleared the scent of incense from a small room in just 30 minutes on the “low” setting. It’s rated to work in smaller rooms than some of the other devices we tested in the same price range, so we think it would work well in smaller spaces that require quieter devices, like the bedroom.

The Levoit Core 300S offers a slew of special features, including a connected smart app that allows you to closely monitor your air quality and control the purifier from afar. The design is sleek and user-friendly, with a twist-off top that’s so easy to open that we think even a child could open and replace the filter if needed.

Another neat feature: The lock button allows you to freeze the interface so that your kids or pets can accidentally change the settings. The only drawback that we could find for this air purifying device is the price, which is higher than the average device of this size.

Dimensions: 8.6 x 8.6 x 14.2 inches | Weight: 6 lbs. | Room Size: 219 square feet

Best for Odor Control: Blueair Blue Pure 411i Max Air Purifier

See at Amazon.com

See at Target.com

Star Qualities

  • Quickly and quietly removed Febreze odor from a small room in less than 30 minutes

  • Filtered out pollen, making a noticeable difference in allergy symptoms

Red Flags

  • Only one button to change all of the settings

Small rooms like bathrooms or kitchens can easily get smelly, but the Blueair Blue Pure Max quickly gets rid of foul odors so that you can breathe more easily. We placed this air purifier in a kitchen, which is usually a source of springtime allergens carried through the window. After letting the Blue Pure Max run for 30 minutes in the kitchen, our runny noses and itchy through miraculously disappeared, as did any lingering scent of Febreze and usual kitchen odors.

The Blue Pure Max unit clears the air of odor and pollen quickly — and does it quietly. We love that the device offers a “night mode,” which is great for even the lightest sleepers. The Blue Pure Max also comes with a connected app that provides real-time air quality measures when synced to the device.

One thing that we found a bit frustrating about the air purifier was that to toggle between the different settings, we had to continuously click one button (which took some time when attempting to set the device to its highest setting).

Dimensions: 18.9 x 10.6 x 10.6 inches | Weight: 7.5 lbs. | Room Size: 526 square feet

Best Energy-Saving: VEVA 8000 Black Air Purifier

See at Amazon.com

See at Homedepot.com

Star Qualities

  • One of the best values and uses less wattage to run

  • Left the air smelling cleaner in just 30 minutes

Red Flags

  • Doesn’t offer any special features

The Veva 800 is a hassle-free air purifier that delivers clean, fresher-smelling air quietly — and for a very reasonable price. The device comes out of the package in two pieces, the base device and the filter. From there, we turned the device on and experienced fresher, cleaner air within 30 minutes of use. Not only is this unit an effective and affordable option from the get-go, but we also found that it used very little wattage to run, which leads us to believe that it wouldn’t surge our energy bills.

If you’re looking for an air purifier that does what it says it will and nothing more, then this economical device might just be your new favorite unit.

Dimensions: 9 x 8 x 23 inches | Weight: 7 lbs. | Room Size: 325 square feet

Easiest to Use: Bionaire True HEPA 360 UV Air Purifier

See at Amazon.com

See at Target.com

Star Qualities

  • Simple, sleek design is easy to use

  • Offers unique features like a UV disinfectant light mode and nightlight mode

Red Flags

  • Highest setting is louder than many of the other air purifiers on our list

The difference that the Bionaire True HEPA air purifier made in our air quality was apparent that we didn’t even need to consult the air quality measurements to know that we were breathing in fresher air. The device comes with three fan-speed settings that range from low to high and a night light mode that’s great for a kid’s bedroom.

The buttons are simple and intuitive to use, and we had no trouble getting the machine up and running. The manual was clear and concise, and the air purifier itself is sleekly designed with a few cool features (an internal UV light to kill bacteria, a 360-degree air filter that sucks in pollution from all sides) but none of the extra frills that might make a device more finicky to use.

Our only gripe with the Bionaire True HEPA air purifier is the noise level, which was a bit higher than some of the other air purifiers that we tested. But, other than that, this model gave us everything that we needed to breathe easy (literally).

Dimensions: 10.98 x 10.43 x 17.01 inches | Weight: 7.98 lbs. | Room Size: 175 square feet

Best Design: Coway Airmega 160 Air Purifier

See at Target.com

See at Walmart.com

Star Qualities

  • Device has a small floor profile

  • Very easy to remove and replace filter

  • Impressively quiet

Red Flags

  • Slightly expensive compared to other air purifiers that clean a similar-sized room

If you’re looking for an air purifier that doesn’t look at all like an air purifier, then the Coway Airmega 160 might be your new favorite device. The device feels more reminiscent of a boxy sculpture than an unsightly air purifier, but rest assured: It also did a great job of cleaning the air. Within 30 minutes of use, the dust particulates were noticeably gone from the previously dusty space. The minimalist control panel was simple for us to get started with, and the buttons felt self-explanatory.

Of all the air purifiers that we’ve tested, this one was the easiest to remove and replace the filter in. The unit is also impressively quiet. It can clean a small-sized room, so that price feels slightly high for the amount of space it covers, but we think it’s worth the price when you factor in the sleek design and impressively quiet noise level.

Dimensions: 13.4 x 18.5 x 6.5 inches | Weight: 12.1 lbs. | Room Size: 214 square feet

What to Know About Air Purifiers

Room Size

All of our recommended air purifiers come with guidelines for room size. If you’ve got a 350 sq. ft. bedroom, for example, you’ll want to check the specs and find a purifier equipped to handle a room that large, such as the Aroeve Air Purifier. As for which room(s) are best to use an air purifier, “most often, I do suggest an air purifier in the bedroom,” Wada tells PEOPLE. “The home office would be another consideration, especially with more people working from home.” Placing one in the vicinity of a cat litter box can help filter out the dust it generates.

Features

Are you all about high-tech gadgets like robot vacuums in your home? Or would you prefer a product to do its job without too many bells and whistles? Check the descriptions for what sort of features are included in each model. Some, like the Levoit Core 300S Smart True HEPA Air Purifier, come with connected smart apps. In some cases, you can save money by purchasing an effective product with simple, streamlined features.

Don’t compromise when it comes to HEPA. “HEPA purifiers have most studies/data with allergens, viruses, etc., so rely on those and that technology,” says Dr. Parikh. “Also remember some things like pollen and dust mites are too small to be filtered so you may need to take other measures for those if you are allergic.” For pet owners, using a pet hair vacuum can greatly reduce the amount of pet-related allergens in the air. Additionally, pet hair removers can also help.

Noise Level

For every person who likes to sleep with a fan, white noise, and sound machine, there’s another who needs a quiet space for sleep. Consider how loud each machine can be when set to low, high, or somewhere in between. We found the Levoit Core Mini Air Purifier to be impressively quiet.

Portability

Air purifiers range in size from small to, “wow, that’s going to take up some space.” Consider the dimensions and tester notes as they relate to how you’ll use the machine. Do you have one particular room in mind? Or do you plan to move it from the living area during the day to the bedroom overnight? Some of our picks are easily portable. Others, not so much.

Behind the Scenes

We tested a total of 38 air purifiers in our PEOPLE Tested lab.

  • Setup: We started with timing assembly from the moment we opened the box until the machine was up and running.

  • Noise Level: Next, we evaluated the air purifier’s design, features, and noise level using a decibel meter.

  • Effectiveness: To test the effectiveness of each air purifier, we set up indoor greenhouses, released a clump of pet hair, and lit an incense match inside. We tested the air quality level before and after using the air purifier. The results were considered on both the low and high settings of each model after five minutes and after 10 minutes. We also used mothballs to test the effectiveness of air purifiers that claimed to filter VOCs.

  • Overall Value: Finally, after evaluating all of the above, we learned the MSRP. Then, we determined the value of each air purifier, given its price versus the testing results.

After testing concluded, we rated each purifier on a one to five scale, with five being the best, against the following testing attributes: setup, design, noise level, features, effectiveness, and value. The air purifiers with the highest average scores ultimately earned a spot on this PEOPLE Tested list.
