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. Thus, 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. At this price you're approaching the cost of buying 2-3 C535s, but you need to weigh in the cost of filters.

Doesn't hurt that it looks pretty nice, too.

I have it set to a routine to run when we go to bed. Owned it for 2 years and happy with it
It's a pretty good one though.
Honestly you probably don't want O-zone generators, they can be harmful long term. If you use one try to limit it to when no one (including pets) are home and wait a few minutes before coming in.
The biggest issue with this unit is the cost of the filters. They are definitely much more expensive than competitors.
But these are POWERFUL and really quiet at the two lower speeds. I use one to cool a server rack actually, its about 3 years now and its still dust free and cool.
