Still not worth it. The 350 CADR rating is the same as a blue air pure 211+. Not quite sure how this thing can filter as much air as it says.

So, as an FYI, this thing uses highly deceptive advertising. Blueair and WINIX use the recommended 4.8 air exchange per hour rating to state their square footage (AKA, an air exchange every 12.5 minutes).

Coway, on the other hand, is using 2 air exchanges per hour to reach the 1,560 square footage. Hence why the CADR doesn't match the hyper inflated claim.

The reality is that this is good for more like 650 Sq ft for the 4.8 air exchanges per hour. So, it is slightly inferior to running two C535s at the same time (360 Sq ft each @ 4.8 exchanges).

So, it's a good filter for a big room, but it's not some massively superior filter like they want to make it seem.

This makes me feel better about picking up a C535 today. Repped
