Airmega 350

So you prefaced 1,400 square feet as "Room Volume". I assume this is still square feet and not 1,400 cubic feet, the latter actually being volume. Purifiers aren't good at removing visible dust particles as they're large and heavy. See the sticky post at the top of the subreddit and our FAQs wiki pa

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

In general, purifiers aren't good at reducing visible dust particles as these are large and heavy compared to "invisible" pollutants like PM2.5. See the sticky post at the top of the sub. Have a look at their product pages. The Coway Airmega 350 has higher Clean Air Delivery Rates (CADRs) than the A

1/2. 6x Winix C909, couple of Coway Airmega 400/Pro X, Austin Air Bedmate, 1 IQAir Health pro plus 3. Winix $160/each, Coways $350/$600 each, Austin Air $800, IQAir $1200 4. Too damn much. About $2,600-2,900/year Looking back if i were to do it again, for my needs, i would have went with all Winix C

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, 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 have 2 Alen 75i with Fresh filters that have pelleted carbon. No smell at all. I bought a Coway 350 and the off gassing was terrible. After weeks, gave up and sent it back. I don't think it was the filter because I smelled it when I first got it and it wasn't running. I think it was the plastic. I

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

The green color is for marketing.I thought the same thing.The green hepa is used on several of their machines. On sale you could buy 3 off the Coway Airmega 450's.The Coway 350 lacks the laser sensor,wheels on the bottom,and less airflow. I bought the 450 for less than $350 and the 350 for $239. If
