If you have been eyeing an air purifier, you’re in luck. Our favorite large room purifier, the Coway Airmega 400, goes on sale for $ 381, which is a reduction of $ 119 from its regular price of $ 500. We initially highlighted a discount at Walmart that brought the price down to a surprisingly low $ 220, but it’s no longer available (Walmart fair dropped the black version at $ 344, but it’s unclear how long that will last). Those deals aren’t the lowest on record – that was before the pandemic – but it’s the biggest drop since early 2020.
No matter where you live, an air purifier is a good idea. Even if your indoor air doesn’t look dirty, it is. Exterior particles and volatile organic compounds (VOCs) enter our homes. Plastics and indoor furniture give off harmful fumes. And there is always dust and animal dander. Along with vacuuming frequently, an air purifier can help keep things under control.
Updated July 8, 2021: The deal at Walmart has ended, but a discount is still available on Amazon.

Is the Airmega 400 right for you?
The Airmega 400 has High-Efficiency Particulate Filters (HEPA) that recirculate the air in a 1,560 square foot room twice an hour. If you use it in a smaller space, it can cycle it four times per hour. It can automatically adjust the settings according to the changing air quality in the room, so you don’t have to think about it. And it has a color-coded air quality ring on the front, so you know your room’s condition at a glance.
It has a pre-filter designed to capture larger particles, which you can wash away, as well as a HEPA filter combined with activated carbon that may need to be replaced. The purifier will notify you when it’s time to do both. They are easy to snap on and off.
