Deal Details
Amazon has a limited time sale on the Coway Airmega 400 True HEPA Smart Air Purifier (Graphite) for $349. Shipping is free.

Product Details:
Designed to clean spaces up to 3,120 sq. ft. in 60 minutes
Combination of a pre-filter, active carbon filter, and HEPA Filter reduces 99.97% of 0.3 micron particles, including pollen and other allergens. It also reduces volatile organic compounds and odor
With its Smart Mode feature, the Airmega automatically adapts to its surroundings by adjusting fan speeds based on the room's air quality; That means your unit is energy efficient without compromising effectiveness
When the air quality in the room remains purified for 30 minutes or more in Eco Mode, the fan will turn off to conserve energy, kicking on again when pollution is detected
When the Airmega's built-in light and pollution sensors detect that the room has been dark and the air clean for 3 minutes, Sleep Mode reduces the purifier's noise and power consumption

I've 2 in the house and they are great. I see $389 now. It hit $349 four times this year, wait and see there's a better price if you don't need it right away.

You really need one for each room. Don't get one giant one thinking it will cover the entire house. So this would be great for probably the living room but probably overkill for most bedrooms. I have an open floor plan so one larger one in the living room/dining room and one in each bedroom.

I saw the filters for these are over $100. Is there a reliable generic? I've been wanting to purchase one of these at this $350 price but the $100 filter is.. a lot. I currently have the 150 and love it despite the filters for this being $50.
