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.

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.

I use horse bedding pellets from Tractor Supply, I pour them on the bottom of the litter bin and then put a bunch of hay on top. It works pretty good, someone on here said they found something even better but I forget the name. As far as air purifiers? Absolutely. A great air purifier sucks up so much fur - not perfect, but I vacuum mine every day so it’s easy to see the good work it does. It’s a Coway Mega. Works very nicely. If they’re shedding fur is crazy then they may be shedding, brushing will always make things easier but the purifier is great

I love my winix plasma wave. I also have a Conway air mega that’s sized for my bedroom that’s been going strong
