Airmega 350

Most brands overstate coverage ratings. If you see a large figure (e.g., 1,500 - 3,000+ sq. ft.), this is likely at 1 to 2 Air Changes per Hour (ACH) which is too low. In any case, Clean Air Delivery Rates (CADRs) are the better metric. The Coway Airmega 400 has a top Smoke CADR of 328 CFM. Based on

ChatGPT is wrong again. I would always source specs directly from product pages. Coway Airmega 350 CADRs: Dust: 376 CFM Pollen: 450 CFM Smoke: 352 CFM Winix T810 CADRs: Dust: 265 CFM Pollen: 267 CFM Smoke: 272 CFM CADRs here apply to the highest airflow speed/setting only. Lower speeds have lower CA

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

Coway Airmega 350/450 are amazing.

Coway Airmega 350/450 would be my pick.

Right, so I don't know your budget, but I believe a CR Box with 400ish CFM would give you around 5 air changes per hour...for borderline excellent air. (4.8 is good, 6 is excellent.) So you want to try to get I believe around 400 or even 500 CFM if you want excellent. A 280 dollar Levoit Core 600 do

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

I would go with the Winix C909 from Costco Canada. Top Smoke CADR is 323 CFM. Likely not a problem in a nail salon, but... the C909 has PlasmaWave, an optional bipolar ionizer. Keep this off if birds are present as it could harm or kill them. (NB: PlasmaWave defaults to being enabled after a power o

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.

Two winix c610 (On sale for 99 each) Levoit everestair (on sale for 300) Airmega 400 (on sale for 350) For us absolutely worth it. The Everest and airmega are newer additions and definitely had an impact the c610 don't have the power the big two have but still make a difference you can tell. Allergy
