Airmega 350

Housefresh.com's reviews are useful, because they measure sound and CADR using a consistent methodology, allowing you to compare among units. They've tested the three you mention. I'd suggest making a table of CADR and noise at each fan speed from their reviews. That's what I did. Based on a quick l

There is the Coway 350 with its pelleted carbon that might be worth checking out if you want to stick with Coway.

For the Coway 350, you would still need 2 for the main rolm and 1 for the bedroom. You cannot base it off of the advertise sq ft coverage. If your ceilings are 8 ft, you would need about 467 CADR for the main room and 200 CADR for the bedroom to get 4.8 ACH. The Coway 350 advertises average about “3

Good brands with affordable units are Winix, Levoit, Coway, Alen, and many more. A Levoit Core 600 for instance is around 280 dollars and does 350 range CFM...almost double the Dyson for 1/4th the cost. Winix + Coway have great units too. (Coway used a fungicide/pesticide on the filters for antibact

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, the larger and more premium Coway models (Airmega Mighty2 AP-1512N / 250 / 300 / 350 / 400 / 450 / ProX) would probably tend to have greater activated carbon weights compared to the Levoit Core 300. But in general, Coway isn't well-suited to regular and/or high concentrations of VOCs.

I'd go for the Coway Airmega 300. That has square prefilters. But the 350 and 450 will probably be great too. The difference with square vs round prefilters is that the round prefilters you vacuum, while the square prefilters you can rinse in the shower.

See the AutoModerator comment. Purifiers aren't good at reducing cat hair as it's very large and heavy compared to "invisible" pollutants like PM2.5. Hair floating very close to the intake will be captured (on a high or the highest airflow speed), but you won't see reductions throughout a room. Free
