Look at filter replacement cost and time/duration the filter lasts most of all. Machines are not nearly as expensive as replacing filters. I have the coway airmega 250, 2 of them now and they're quiet, self air quality checking and look decent, and filters aren't bad to maintain.

I have a Molekule and it’s sitting stored. The replacement filters are expensive as hell, and I find my BlueAir (the 211+) and Coways (Airmega 250 and 150) to be better. The latter aren’t “smart,” (although I think you have that option now), but I have them plugged in with smart plugs and I like that the Coways signal when the air quality changes like a basic air quality monitor would.

Yes, because I live in an old building. I have a Coway 1522hh in the living room, and an Coway Airmega 250 in the bedroom

Highly recommend coway airmega 250 which is out of stock on their website but in stock on Amazon. I bought used like new for a little under 300 US which as of this comment used like new is still in stock. My partner has severe asthma to dust and cats, he was waking up nightly having full asthma attacks. Since we've gotten it a week ago (we run it most of the time) he hasn't had a bad asthma attack. The used like new was brand new for me, it just came in the wrong product box (no original packaging). It was recommended to me here by /u/UncleGurm who is the air pro-ifier.
