Once you’ve gotten used to an air purifier, it’s hard to go back to life without one. I really appreciate them in the winter because they make the air feel less stale when I can’t open my windows. And let’s be real—they’re a lifesaver during the warmer months when allergies can run rampant thanks to all the pollen in the air. We’ve personally tested a variety of models for our air purifier guide, and Coway’s offerings have consistently stood out as favorites. Right now, their stylish Airmega line is discounted by up to 30 percent—pretty close to Black Friday prices. This sale ends on January 30, so if you missed out on buying an air purifier during the holiday season, now’s your chance. Be sure to also check out our recently updated buying guides, including the Best Ventless Fireplaces, Best Office Chairs, and Best Blenders.
WIRED Featured Deals:
Coway Airmega Mighty Air Purifier for $170 ($60 off)
This affordable air purifier offers great value, even when not on sale. Right now, it’s at its best price since Black Friday, just $30 shy of that deal, and it typically doesn’t drop this low outside of seasonal events. It can clean a room up to 361 square feet, effectively exchanging the air 4.8 times per hour. For optimal noise levels, it’s best to use it in a slightly smaller space. It includes a built-in timer for automatic shutoff after one, four, or eight hours, and there’s an Eco Mode that powers it down after 30 minutes of no detected pollution.
We like its color-coded light indicator, which turns blue for clean air and purple or red for varying pollutant levels based on the built-in air sensor. This sensor also automatically adjusts the fan speed. The device is portable, featuring a back handle, and replacement filters are affordable (WIRED editor Kat Merck owns one and buys these regularly), plus it comes with a three-year warranty.
Coway Airmega ProX Air Purifier for $720 ($279 off)
This hefty air purifier is the most effective option we’ve tested for homes with high ceilings. It has a bit of a Dune-like design, but it can clean the air in a 1,000-square-foot space four times per hour at its highest setting. It operates quietly at around 50 decibels at its loudest, and it features a control panel lock to prevent accidental changes.
It includes Coway’s air quality indicator light, which shows blue for good air quality and red for poor, allowing for easy monitoring. It has three airflow speeds and an auto mode that adjusts fan speed when necessary. While it weighs about 50 pounds, it comes with built-in wheels and handles for easier movement, plus a solid five-year warranty.
Coway Airmega 50 Air Purifier for $63 ($17 off)
This compact model got an honorable mention in our air purifier guide—check out our in-depth review here—but it’s a solid choice for smaller spaces. Following CDC recommendations, it can clean air effectively in areas of up to 100 square feet five times an hour. It’s about the size of a roll of paper towels, and the large indicator light on top is easy to see from across the room. It also offers a built-in timer and a nightlight. Covered by a three-year warranty, this device is perfect for anyone who needs a smaller purifier for their living room, kitchen, or bedroom from a reliable brand—especially at this price.
