My Coway 230 plays nice with smart plugs and restores power after loss. The other Coway purifiers e.g. 150/160 probably do as well. However, Coway has been really shit lately about EOLing products suddenly (Coway 230 isn't even available for sale anywhere, despite being hands-down their best-looking and overall best purifier they have ever made ... they literally EOLed their best product and reason to exist as a company) On the upside though, Winix 5500-2 filters (which haven't changed in years) fit fine inside my Coway with a margin around the edges and I will just laser cut an adapter frame and use Winix filters in it in the future If you're handy with EE stuff, I find that my old hideous-looking Winix 5500-2 doesn't restore power after a loss but if you \*hold down the power button permanently\* it will power on after a loss. So all that's needed is theoretically to jumper the power button permanently.

Sorry to interrupt here. Would a Coway 230 be ok? I have one and have a similar situation.

Thank you! My brother owns the home I live in. Mold is growing on the window pains of my bedroom where I sleep. My brother won’t fix it and I sure don’t have the money. I don’t touch the mold. It’s just siting inside all the sills and growing. Ughh!!

wait why? i have the 230 and they discontinued it supposedly because it was too similar to the 240. and now they're discontinuing the 240 and 250?? are they bad models or something? :(

230 also has decent foam seals. So yes. That said, remember mold REQUIRES REMEDIATION, a purifier is clean-up or band-aid for mold.

These worked very well for me when my area was inundated with smoke. My house is old and porous, so it was fairly smoky inside without them. I started with one that I would move with me from room to room. I now have 3 plus one smaller model. Edit: Coway has another model that is exactly the same but with a nicer looking front plate. I think it might be the 200?? I don’t know for sure. It takes the exact same filters as the 1512.

Agreed, whatever that is is crazy expensive. I use Coway Airmega HEPA purifiers on two levels of my apartment and a smaller Levoit unit at work, at much lower price points.

bought a coway air mega last yr. no complaints, no smells ever :) tried that box fan nonsense-even after sealing all gaps around frame/filter, still mostly recirculated the air right near it. worked terribly (regular 20 buck lasko box fan)

I bought an Airmega for our bedroom a year ago. My wife says my nighttime snoring has almost completely stopped. We ended up being so happy with it we bought another for the DR/LR.
