Airmega 400

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

Coway purifiers are top notch. i have an AirMega 400 model in the room where we keep our cat litter boxes. it's built like a tank and after a year, it still showed the filters at maybe 75% remaining. i replaced them anyway, as i know the carbon pellets were spent without a doubt, and wanted to comba

We tend to recommend Coway first because of the high quality. The Airmega 400 is full price at Coway right now and I do not recommend buying it until it's dropped to $400 or less.

No, Dyson is one of the worst! The HP09 has terrible Clean Air Delivery Rates (CADRs). They just know how to market effectively. As Rule 4 and the AutoModerator comment repeats, it's helpful to know the ceiling height. I'll assume it's 2.4 meters. 60 m2 x 2.4 = 144 m3. For rooms measured in meters,

Hello. Very sorry to hear about your husband's IPF. You're right to be wary of ChatGPT. I'm sure it's improving, but I've seen it produce inaccurate or totally incorrect information. Just a quick FYI: purifiers aren't good at reducing visible dust as it's large and heavy compared to invisible pollut

If you have high concentrations of particulates (e.g., pollen or smoke particles) and VOCs (which are gases), you need two types of air purifier. This is because most purifiers have very little activated carbon or other sorbent media by weight for gases/vapors/odors/VOCs. Instead, they're designed f

I've had one of them for over 7 years, so there may be better options out there by now, but I have the Coway AP-2015F Airmega 400. It's for 1560 sq feet and I live in a (decently sized, but still) studio apartment, so this is already overkill. Love this thing. Then when the fires hit, I got another

For $349? Absolutely. On its highest airflow speed/setting, the Airmega 400 would be suitable for a max. room size of 492 sq. ft. (8 ft. ceiling) based on the AHAM 2/3 rule. Just be sure to check replacement filter prices. Coway has a subscription model + bulk discounts. Retailers like Sylvane also

See the AutoModerator comment. Purifiers aren't good at reducing visible dust particles as they're large and heavy compared to "invisible" pollutants like PM2.5. An even stronger argument could be made for dog hair. If you don't have one already, I'd get a good quality bagged vacuum cleaner with a H

You would probably be fine with some corsi Rosenthal boxes...as rabbit air is better for smoke/odors/VOCs I think.. They don't move much air. Therefore a 90 dollar Levoit will probably filter more air than a rabbit air (which is great though if you have issues with odors/smoke/VOCs etc.) So the Cowa
