Coway air purifiers on sale for $365 at Walmart

TL;DR: Buy a life-changing Coway Airmega 400 air purifier on sale for $365.50 at Walmart. That’s over $350 off of the (somewhat inflated) original price. 

You’ve survived another hot summer, and it’s all thanks to your trusty portable air conditioner. But with the end of “Hot Girl Summer” comes the beginning of allergy season and “Sniffly Gal Fall.” All that extra junk in the air requires a solid air purifier to help you enjoy the cooler weather free of allergens. 

The Coway Airmega 400 graphite smart air purifier is on sale for $365.50 at Walmart. This means you save $352 (almost 50%), but you should be aware that Walmart has inflated the regular price a bit. For reference, Amazon has it for the same sale price but the regular price is listed at $605 for 40% total savings. But pricing trickery aside, this is still one of the lowest prices we’ve seen for this popular air purifier brand. 

Made to cover up to 1,560 square feet, the Airmega 400 is built for larger living spaces. It won’t take up too much space in your living room, since it’s about 22 x 14 x 14 inches. As far as noise level, the most it puts out is around 50 decibels, so about the same ambient noise as your other appliances at high settings and practically silent at lower power modes. 

Built with a dual HEPA air filter, the Airmega 400 promises to remove 99.97% particulate air matter. It also includes a pollution indicator so you can monitor your air quality in real-time. Tiny particles like pollen are no match for the activated carbon and True HEPA filters, and it also comes with a washable pre-filter to catch larger dust particles. And it’s smart mode allows it to adapt automatically to different fan modes for the most efficient filtration.
