While spring brings warmer weather and the opportunity to spend more time outdoors doing the activities you love, it also kickstarts allergy season. Lucky for us, it's also time for the Amazon Memorial Day Sale—which means huge savings on healthy home devices, like a high-quality air purifier, which can help improve the air quality in your home and fight seasonal allergies. In fact, the Amazon Memorial Day deals are so good, you can score a HEPA air purifier for as little as $30 right now.

Some air purifiers just work to kill germs and get rid of odors—and if this is all you need, you can grab an air purifier for a steal at under $30 at the Amazon Memorial Day sale. But if you're looking for help against pollen, pet dander, or pathogens, make sure the device uses a true HEPA filter. These are regulated by the U.S. Department of Energy and supported by the Environmental Protection Agency (EPA) to be effective at removing up to 99.97% of dust, pollen, and particles as small as 0.3 microns.

Research has shown that air purifiers, namely those with true HEPA filters, can help improve indoor air quality in your home and eliminate allergens. In fact, a 2020 study out of Korea found that consistently running air purifiers with HEPA filters can help reduce symptoms for folks with dust-mite allergies, while a 2015 study reported that air filters effectively reduce most indoor air pollution and irritants, thereby reducing allergy symptoms (including from seasonal allergies and pet dander). Meanwhile, a 2021 summary from researchers at the CDC suggests that air purifiers with a HEPA filter may also help filter out the virus that causes COVID-19.

Other than a HEPA filter, most additional features of air purifiers are dependent on your preference, like odor-blocking charcoal filters and germ-killing UV lights. Another consideration when buying an air purifier is the size of the rooms you're in most often, as price and size tend to directly correlate with the square footage the machine can handle. Plus, some brands even note how quiet the air purifiers are (even to the exact decibel, or degree of loudness), and whisper-quiet devices can make a much better option for nurseries, offices, or bedrooms.

Even though that sounds like a lot of research to do before even adding an air purifier to your shopping cart, there's no need to feel overwhelmed—we've done the leg work for you. Below are nine of the best deals available through Amazon's Memorial Day weekend sale on high-quality air purifiers to improve the air you breathe at home.

Honeywell HPA300 HEPA Air Purifier

Buy It, $212 (was $270)

This air purifier is designed for extra-large rooms (up to 465 square feet), circulating air in the space nearly five times per hour. It uses a HEPA air filter to capture up to 99.97% of microscopic airborne particles including dust, pollen, pet dander, and smoke—and that power is backed by more than 18,000 five-star ratings on Amazon. The Honeywell air purifier has four speeds; although reviewers point out that it's a bit loud at higher speeds, "the 'germ mode' (low) is fantastic, barely noticeable as far as noise level," wrote an Amazon shopper. If you're looking for an efficient machine that can purify a large room, the Honeywell HPA300 at just $212 is a great deal.

Using a four-stage filtration system that includes a true HEPA filter, this air purifier not only filters out 99.97% of microparticles like pollen, pollutants, and allergens, but it also reduces volatile organic compounds and odors. It uses an LED light to let you know how clean or dirty your air is in real time, and it has a timer, three fan speeds, and an eco-mode to use less power once it detects no pollution for 30 minutes. The nearly 14,000 five-star ratings on Amazon not only confirmed the Conway's quality, but also praised how quiet it is while doing that job—a feature hard to come by in air purifiers.

Pure Enrichment PureZone Air Purifier

Buy It, $80 with on-site coupon (was $130)

The Pure Enrichment PureZone can effectively clean a medium-size room (200 square feet) using its three-stage air purification process, which includes both a true HEPA filter and a UV-C light. This last stage helps add a deeper level of cleanliness by also zapping 99.9% of viruses and bacteria like staphylococcus albus (which can cause infections), in addition to the average allergens and pollutants. Weighing just 8 pounds, this device is small and lightweight, so you can move it from room to room with ease. With more than 12,000 five-star ratings, Amazon reviewers praised the quality and price point, but also the fact that PureZone's replacement filters only cost around $15, so it's an economical investment overall.

What's more, it comes with a lot of bells and whistles while still being an affordable option. This air purifier syncs with Alexa and Google Assistant for voice command, and offers a remote on your smartphone, so you can change the speed or turn it off without having to get up. In addition to filtering your typical pollutants and allergens, this purifier also utilizes a custom high-efficiency carbon filter to neutralize smoke and odors—and can do all of this on auto mode (it scans the room to find new irritants in the air and purify as needed). It's quiet, effective for many folks with allergies, and comes with great customer service from the company, according to Amazon shoppers.

This one from Hamilton Beach can clean a space of about 140 square feet, with the air moving through three filtration stages to get rid of microscopic particles. What's more, it has a permanent HEPA-grade filter, which means you can vacuum it clean instead of having to replace the filter—saving you the headache of ordering replacements, as well as money, in the process. It has three settings, including a whisper-quiet mode for nighttime. Amazon reviewers shared that it really helps with their allergies, and one allergy sufferer even claimed to have been "cured" completely thanks to this air purifier.

Hathaspace Smart Air Purifier

Buy It, $230 (was $300)

Germ Guardian GG1000 Air Purifier

Buy Iit, $34 (was $39)

If you're looking for more of an odor- and pathogen-remover than an air purifier for allergens, the Germ Guardian is small, well-priced, and effective. It doesn't have a HEPA filter, but it does utilize UV-C light to help kill airborne viruses and reduce odors. Without filters to replace, cost becomes even more enticing, especially with a $34 sale price right now. This device mounts on your wall plug, similar to an air freshener plug-in, so it is truly small enough to stay out of the way. Amazon shoppers pointed out how they love plugging this in the kitchen or near their cat's litter box to keep odors at bay. And even though it doesn't have a HEPA filter, reviewers reported they cough and sneeze a lot less when this little guy is cleansing a room.
