Levoit will still clean your air. They even publish PM2.5 CADRs for most of their models. While the Levoit Vital series and EverestAir perform very well, they may not have the build quality of the more premium Coway units. Is it better to slightly oversize units so they’re effective on medium/quiet

You can't go wrong. I just bought 3 replacement filters from them. 2 for my Winix 5500-2 and my Coway Airmega 350. They fit like a glove and work great.

Well it depends what setting is she running it on, how far away is it, how is it angled ? Etc. As I have a box fan next to a Levoit 300 I am looking at now. Apparently box fans can be 45-65+ decibels depending on low/medium/high The Levoit 300 got 64 decibels in a comparison test in the video below.

Wait until the Coway Airmega 450 goes on sale. This unit moves a ton of air if you can deal with the noise.I picked up a white one for about $350 around Christmas.I think the 400 was on sale a while back for $349.

However, the Smoke CADR is probably lower than 141.2 CFM. For the bedroom and office, I think minimum CADRs should equal the square f
