Coway Airmega Mighty Air Purifier for $170 ($60 off)

the The best affordable air purifier Offers excellent value for the price, even when it’s not on sale. This is the best price we’ve seen since Black Friday (and it comes within $30 of that cost), and it’s usually no cheaper than it is now outside of seasonal shopping events. It can clean a room up to 361 square feet, exchanging air at a rate of 4.8 times per hour. We recommend running it in a slightly smaller room to allow for lower noise levels. It has a built-in timer that allows for automatic shut-off after one, four or eight hours, and there is an economy mode that turns it off after 30 minutes without detecting contamination.

We like this purifier’s color-coded light, which shows blue for clean air and purple or red for different levels of pollutants based on the built-in air sensor. This sensor can also automatically adjust the Mighty’s fan speed. The entire device is easy to transport, thanks to the built-in rear handle, and replacement filters are inexpensive (WIRED editor Kat Merk has a Mighty and Buy this), and has a three-year warranty.

And we mean small; Following the CDC’s recommendation, it can effectively clean the air in a 100 square foot space five times per hour. But it’s also about the size of a roll of paper towels, and the large indicator light on top is easy to spot from across the room. There is a built-in timer and night light as well. It’s covered by a three-year warranty. If you don’t need to cover a lot of space, but still want a small device to freshen up your living room, kitchen, or bedroom from a trusted, proven brand, this is a safe bet — especially at this price.
