The 12 Best Air Purifiers With HEPA Filters, According to Customer Reviews

Best Overall: LEVOIT Air Purifier LV-H132

BUY IT

This compact air purifier may seem tiny, but its impact will be felt around your entire home—just ask more than 6,400 Amazon reviewers. It uses a three-stage filtration system to purify 99.97% of all airborne contaminants in the air, so your space will not only feel cleaner but also smell better.

The rapid purification process takes the air through a fine filter that traps large particles (like hair and lint) first, then through a true HEPA filter for small particles (like dust mites and pollen), and finally, through a carbon filter that removes odors. Even though it's powerful enough to circulate the air in one room over four times per hour, the purifier is also quiet enough that you'll be able to get a full night's rest if it's in your bedroom—there's even a night mode that dims all the lights.

One five-star reviewer wrote that Levoit "hit the nail on the head with this purifier," which they praised for noticeably catching dust and dirt in the filter in just two weeks. Their only regret? Not buying this air purifier sooner.

Best for Allergies: GermGuardian True HEPA Air Purifier

BUY IT

Common allergens—including pollen, pet dander, mold, and dust—are zapped from the air with this ultra-quiet purifier through a combination of UV-C light and filters. The included charcoal filter reduces the scent of powerful odors (like last night's dinner), before the HEPA filter removes dust as small as .3 microns and purifies the air around it (up to 167 square feet).

One longtime allergy-sufferer called it a "godsend", while another five-star reviewer raved they would 100% recommend this to any allergy sufferers— it "made such a difference" they wrote, that they don't even need their allergy medication anymore.

Best for Mold: Alen BreatheSmart 45i Air Purifier

BUY IT

This elegant purifier may look like a chic home accessory, but it actually houses a super powerful HEPA purification system that removes dust, bacteria, and chemicals from up to 800 square feet of space. The streamlined design stands out from other purifiers because the HEPA filter is coated in an antimicrobial compound that stops bacteria and fungi growth, making it a top pick for homes or apartments with mold issues. Plus, the smart purifier gives you real-time air quality updates through an LED color display that shifts between red, orange, green, and blue to reflect the range of dirty to clean air.

You'll even want this purifier in your bedroom. It emits soft pink noise that lulls you to sleep, and can be ordered in seven different wood and metal colors to perfectly match your room decor. An artist with mold and seasonal allergies wrote on Amazon that this "works amazingly well" in their attic studio and quickly clears the air of toxic fumes from paints, stains, and other chemicals.

Best Eco-Friendly: Coway Mighty Air Purifier

BUY IT

This eco-friendly air purifier makes the air inside your home feel just as fresh as the great outdoors with a powerful four-stage filtration system. The built-in air quality sensor indicates the air pollution level, and you can control the strength of the purification system with three different fan speeds or even set a timer for maximum purification.

It also uses the sensor to trigger eco mode: When no pollution is detected in the air for 30 minutes, it stops the fan to save energy and money on your electric bill.

One happy reviewer said it's so energy-efficient that running the machine continuously, even while at work, didn't increase their energy bill.

Best for Pets: Winix HR900 Pet Air Purifier

BUY IT

If your pet's scent is the first thing to greet you at the front door, then it's officially time for you to invest in an air purifier. While the five-stage filtration system makes this a great choice for any home, it's actually designed with pets in mind—the washable pre-filter captures pet dander before air even enters the true HEPA filtration. Then, a carbon filter with advanced odor control captures household and pet-specific odors (while also extending the life of the pricier true HEPA filter).

Called a "must-have" by a five-star Amazon reviewer with five pets, the power of this device to disguise pet odors and reduce dander in the air was also praised in more than 300 additional reviews.

Best for Smoke: Levoit MetaAir True HEPA Air Purifier

BUY IT

To ensure your air purifier protects against smoke, it's extremely important to replace the air filters regularly, according to a previous interview with Sanjeev Jain, MD, PhD, board-certified allergist and immunologist at Columbia Allergy. Dr. Jain warns clogged filters are less effective and could put you at risk.

His pick? This Levoit model, which uses both HEPA and carbon filters to purify up to 538 square feet of air and has a built-in particle sensor that adjusts fan speeds. Plus, a dozen reviewers wrote it was effective for removing smoke from the air, whether from cooking, cigarettes, or wildfires.

Best Portable: Pure Enrichment PureZone Air Purifier

BUY IT

Small enough to move from room-to-room in your home, this compact purifier uses a three-stage filtration system—an odor-reducing carbon filter, a true HEPA filter, and a sanitizing UV-C light—to rapidly clean the air.

Quiet enough to use in a bedroom or nursery, it's still powerful enough to purify up to 200 square feet and can even be used on a power-saving auto-timer function. Plus, it comes with a five-year warranty, so you won't have to worry about a replacement anytime soon.

The portable find also has a near-perfect five-star rating on Amazon with with more than 6,800 five-star reviews. One shopper even wrote it "one of the best investments for good health."

Best for Large Spaces: Honeywell True HEPA Allergen Remover

BUY IT

Already powerful enough to purify up to 465 square feet of space, this heavy-duty air purifier also offers a "turbo" setting that quickly captures pet dander, pollen, dust, mold, and smoke. It sends polluted air through a carbon pre-filter (that absorbs gasses and odors) and a HEPA filter, before recirculating the air back into your space up to five times an hour.

The best option for purifying large rooms or spaces (like a garage or basement), you'll love that the machine helps you breathe easier (just ask over 1,500 five-star reviewers) and is super easy to maintain. Plus, a handy filter light reminds you to replace the pre-filter every three months and the HEPA filter once a year—and thankfully, no tools necessary!

Best Budget-Friendly: JINPUS Air Purifier with HEPA Filter

BUY IT

While most budget purifiers ditch the critical HEPA filter to save on costs, this affordable find still uses a three-stage filtration system (including a true HEPA filter) to purify spaces up to 161 square feet.

This streamlined model offers two modes: a sleep mode, which reduces brightness and automatically turns off after eight hours, and a normal mode. The compact machine runs off USB power (you'll have to supply your own plug adapter) and needs a HEPA filter replacement every six months.

Unsurprisingly, the more affordable pick has already earned more than 2,900 perfect ratings from happy owners who praised this small-but-mighty machine's ability to get rid of smoke, pet odors, and allergens. Plus, the under-$50 price point really can't be beat.

Best for Sleeping: Eureka Instant Clear Air Purifier

BUY IT

Even though the sound of subtle white noise can help soothe you to sleep, it's not necessary for an air purifier to make it. Luckily, this model has a built-in sleep mode that turns off any lights and reduces the sound to just 32 decibels (about the noise level of a whisper)—so if you're super sensitive to lights or sounds, you'll have no trouble falling asleep with this option in your bedroom. The air still goes through a three-step purification process—including a carbon filter, true HEPA filter, and UV light—but you'll barely be able to hear the machine.

One five-star reviewer wrote about how quiet the sleep mode is, claiming they "honestly cannot hear it running on low setting" and only know it's running because they "can feel the slight breeze." Plus, the energy-efficient model has a built-in filter replacement light, so you know when it's time to order a new set of filters.

Best for Odors: Winix 5300-2 Air Purifier

BUY IT

You'll be able to *smell* the difference in your home from the moment you kickstart this air purifier's three-stage filtration system. The Plasma Wave filter breaks down odors (along with other allergens and chemical vapors) at a molecular level using ions, so your indoor air is not only cleaner, but actually smells better, too.

You can use this purifier in manual mode (with four speed options) or opt for sleep mode, which dims indicator lights and reduces the fan speed. Powerful enough to purify up to 360 square feet, it also has a built-in sensor to report on your room's air quality.

Best of all, one owner compared the purified air in his home to "country fresh air" before confirming that "it really does eliminate odors."

Editors Pick: Coway Airmega 150 True HEPA Purifier

BUY IT

The arrival of this air purifier coincided with the addition of a new dog to e-commerce health and wellness writer Braelyn Wood's apartment. One year later, she can't believe how well the three-stage filtration works to filter out dust and pet dander, as well as any scent traces of her pup. She allows it to run continuously on auto mode, which adjusts the fan speed and filtration to the level of pollution.

Not only does her bedroom smell cleaner — it's well below the 214-square foot max — but the air purifier actually looks like chic decor thanks to its sleek design and modern sage green colorway.
