15 Best HEPA Air Purifiers (Review) In 2021

The Unclutter best choice purifier with HEPA filter, the first of the LEVOIT brand we reviewed. The LEVOIT Air Purifier for Home cleans the air 5x per hour, making it an efficient and powerful purifier that works around the clock to clean the air in the room you place it. It has a CADR of 135+ in order to remove dust, pollen, and allergens, and filter replacement is recommended for mold and spore removal. It has a three-part TrueHEPA filtration system designed to collect and break down fabrics such as pet dander, airborne particles, and then carbon molecules. Since it operates so quietly you can carry on undisturbed.

The Coway AP-1512HH White HEPA Air Purifier has four stages of filtration, the first of which is a washable filter which is the one that catches fibers to break down through its process. It has an active carbon filter that is designed to clear odors too. The fan speeds can be controlled manually or automatically and the device has a neat air quality monitor that cleverly detects pollution. The manufacturer has designed this model so that if no air pollution is detected within 30 minutes, it will auto-change to eco mode saving energy and reducing the noise level. The TrueHEPA means that it captures 99.97% of particles up to 0.3 microns.

The Germ Guardian True HEPA Filter Air Purifier is actually a rather smart looking device and slightly more affordable than our best value pick. Standing at 22 inches tall it can fit neatly into most spaces as long as it has space to operate freely. It works at 4x, that is it cycles four times per hour for efficient breakdown of particles, and the main filter, when it needs to be replaced, is easily supplied by the manufacturer. It claims to collect 99.97% of harmful pollen, dust, and allergens as small as 0.3 microns and works well in spaces up to 167 square feet so it’s great for smaller rooms, offices, and even student dorms.

The Winix 5500-2 Air Purifier with True HEPA is an upgraded version of a previous model and has lots of added family features making it ideal for the home. It has a visual air quality sensor, light sensor, remote control, auto and sleep modes, and four fan speeds so that you can turn it up or down as needed. You may or may not like the black design which looks like a small industrial unit rather than other sleek counterparts we have in our review list.

As far as smart air purifiers work, wait for it, with Alexa through WiFi using the correct app so that you can use voice control. Not only that but it still works well, fancy that! It clears the air at 4.5x air changes per hour and when tested it has proven great for bedrooms, kitchens, and living rooms as well as office space up to 360 square feet. Like all the air purifiers in our review list, the LEVOIT LV-PUR131 Air Purifier for Home has a true HEPA filter that breaks down particles after the pre-filter picks up fibers, then uses an activated carbon filter for cleansing odors.

We chose the LEVOIT Vital 100 Air Purifier for Home for its unusual design. While it’s quite large it might not suit everyone but despite its design, it doesn’t lack in power. That said, it’s perfect for use in smaller rooms and works well and quietly on its lowest setting. It works to clean the air around you and as all TrueHEPA filters it will manage the air and break down as much as 99.97% down to as small as .3 microns. This model does run quietly unless you sit it on tiled flooring and is best placed in a corner where there is space. It’s powerful while being efficient and with measurements approximately 13 x 6.3 x 16″ it won’t take up so much space while doing its job. This model weighs little more than 10 pounds so it’s easily moved if you need to take it into another room. Oh, and it has a washable pre-filter which means you can clear all of the larger fibers that it collects.

If you need to clear your air of pet dander, hair, pollens, and pollutants, take a look at Hathaspace Smart True HEPA Air Purifier which not only looks good but works brilliantly. It works in real-time to pick up on the quality of the air in your space so lets you know how polluting the air is that you’re breathing through the lights that change from red to green through amber and will change accordingly. This model comes with remote control and a two-year warranty and an almost silent sleep mode for those night times that you really need to relax.

Where the quality of air in our working and living space is becoming ever more important, perhaps a medical-grade air purifier is what you need. The Medify MA-25 B2 Medical Grade HEPA Air Purifier is a powerful device that uses H13 filters which are more effective than TrueHEPA – this one is tested to intake microns as small as 0.1 particles compared to 0.3 microns with the other models on our review list aside from the hOmeLabs model you will see below. At its fastest, it will clean a room of 250 square feet in just 15 minutes and up to 1000 square feet in an hour. You might like its design which is black or white, sleek, and almost looks like a speaker from an old music system.

This little RabbitAir MinusA2 Ultra Quiet HEPA Air Purifier beauty might be expensive compared to other models but we discovered a few reasons for this. It looks fantastic – a sleek, sturdy design – and can sit on a desk, tucked away on the floor (as long as there is room around it to operate effectively) and you can choose to mount it on a wall too. Bearing in mind, however, although it’s less deep than ‘box’ style devices, it is still fairly bulky largely due to how many filters it has to deal with. You might like the idea that one of the filters can be customized. Choose from germ defense, pet allergy, toxin absorber, odor filter. You can even select a special edition model so that the screen shows a bit of art instead of looking too techy.

The Blueair Classic 480i Air Purifier is a great choice as far as air purifiers for large rooms as well as smaller areas go, making it ideal for cleaning the air and breaking down particles such as dust, mold spores, pet dander and other pollutants in bedrooms, kitchens and other rooms in the house or in the office. It is our premium pick for those with a larger space and a larger budget. You might like that through the Blueair app it can work with Alexa for real-time scheduling. This means that you can set the timer and adjust the speed, and even set it for quiet levels (less powerful) at night time. And, in case you forget, the indicator on the device will let you know when the filter needs to be replaced, which should be 6 months at the most.

This nice-looking Honeywell True Hepa Allergen Air Purifier filters air at 5x per hour to intake and break down pollen, dust, pet dander and smells from the air. It has easy to control touch buttons to set the fan speed, timer, and auto-control dimmer for using less light pollution which is especially handy during the night when you don’t want the dark to be disturbed. There’s a filter check option so you know when replacements need to be put in place and also promises to help with viruses, bacteria, and other pollutants. With the TrueHEPA filter, it will remove 99.97% of particles as small as 0.3 microns.

The Holmes Small Room 3-Speed HEPA Air Purifier is a smaller model than most of those in our review list and it’s lightweight at less than 6 pounds so it’s easy to move. We decided this was the best value purifier on our list. Our team found it sat on a desk or work surface so it was ideal for the office or the kitchen and works fairly quietly if you choose to set it in the bedroom or sleeping space. It uses a UV c light bulb which doesn’t need replacing very often, this type of LED is designed to help purify the air so works to compliment the air intake of the Holmes purifier.

This is the second of our lightweight air purifiers that are specifically designed for small spaces. At 200 square feet of air cleaning, it’s great for dorms, small apartments, or separate rooms. We chose the Pure Enrichment PureZone 3-in-1 Air Purifier for its cute design and the fact that it’s so lightweight you could even move it around the house or office depending on where you spend the most time. While it’s quite small it might not suit everyone but it works quietly and has a UV c light for added purification. As all TrueHEPA filters promise, it will manage the air and break down as much as 99.97% down to as small as 0.3 microns and it can be placed on the floor or on a surface provided it has space around it to operate effectively. This model weighs just 6 pounds so it’s easily moved, and the 3 stage filters clear larger fibers as well as breaking down airborne particles such as dust, pollen, and pet dander. It’s nice that even for a smaller device it is powerful enough to clear air within 200 square feet.

Where the quality of air in our working and living space is vital to some of us, we don’t all have the large space that needs a large device to clear the air around us. We also don’t all have a huge budget so our budget pick is this sweet looking device and it’s not our choice because it’s cheapest on our list, it isn’t, but it has the TrueHEPA H13 filter we mentioned earlier which is more effective than a TrueHEPA the hOmeLabs Air Purifier is one of two of the H13 models we reviewed on our list, the other being the medical-grade Medify MA-25 (above). For such a small purifier it works well in really small spaces, so, in our opinion, it is good for use in an office or working space, and small sitting rooms or bedrooms. Pop it next to a desk or towards the bottom of the bed and take advantage of the H13 filter which is more effective than TrueHEPA. Even if you choose to use it in the kitchen or other living space, it will clear microns as small as 0.1 particles compared to 0.3 microns with other True HEPA models so it’s great for reducing cooking smells, smoke, and mold spores as well as additional allergens and pollutants.

The TaoTronics HEPA Air Purifier is a superbly designed small air purifier. Using a pre-filter, TrueHEPA filter, and carbon filter its 3 stages of filtration work beautifully in smaller rooms. It is so lightweight that it’s easy to move from room to room should you need to, although we found it so small we had to put it well out of the way of usable space so we didn’t knock it over or trip over the power cable. That said, it’s best placed near to a socket on a desk or other surface. It’s a cute little pet and child-friendly model with a night light that can be switched off if you don’t want to be disturbed or distracted while you sleep. We were also wary of some details and reviews provided when we researched.
