5 Best Air Purifier Deals: For Big and Small Spaces

Brenda Stolyar

spring means warm sunshine, comfortable temperatures, and later sunsets (thank you, daylight saving time). Unfortunately, it also comes with seasonal allergies. Many of us are plagued with a runny nose, itchy eyes, and constant sneezing, among other irritating symptoms. During these troubling times, I highly recommend investing in an air purifier to help keep your home free of the pesky allergens that seep in from the outside. Below, we've gathered great deals on a variety of WIRED-approved air purifiers for spaces big and small.

Coway Airmega 200M

Effective in spaces up to 361 feet, the Airmega 200M is our favorite air purifier for small rooms. It's both compact and attractive, so you won't have trouble finding a proper place for it in your home. It also comes with an air quality monitor that increases the fan speed whenever it detects particles and turns the device off when it doesn't detect pollution—a nice way to save energy.

The Pure Fan Auto is a great option if you're looking for a quiet air purifier—it cycles air five times an hour in a 362-square-foot room. It doubles as a fan too. It's not strong enough to cool down an uncomfortably hot room, but it feels nice to sit in front of. Light sleepers will also appreciate its Night mode feature, which switches the fan to its lowest setting and shuts off the air quality indicator light. This is the lowest price we've tracked to date.

This received an honorable mention in our roundup of Best Air Purifiers. It's rated for smaller rooms, specifically between 180 and 320 square feet. It packs an H13 HEPA filter, along with support for Google Assistant, Alexa, and HomeKit (which is great if you have an iPhone). It also comes with a handle to carry it from room to room, and it noticeably revs up when there are more particles in the room than usual.

Wynd Plus

If you're taking a well-deserved vacation any time soon, we suggest adding the Wynd Plus to your packing list. As one of the smallest air purifiers on the market, it fits in a cup-holder in the car and on a nightstand. Even though it's not a HEPA filter, it's still capable of cleaning particles greater than 0.3 microns within 3 feet. It comes with an air quality sensor, a kickstand, and a microfiber traveling bag as well. It's dipped as low as $155, but we still think this is a solid deal.

This deal is only available for Amazon Prime subscribers. If you're not sure whether you need an air purifier, we recommend getting an air quality monitor. The Temptop M10 not only tracks the total volatile organic compounds (TVOC) and levels of formaldehyde (CH2Ol) but also the general air quality index (which measures particulate matter that is 2.5 micrometers or smaller, such as wildfire smoke). It doesn't, however, track CO2 or humidity. It dipped lower to $76 last month, but it doesn't fluctuate in price often.
