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

Do you know the dimensions of the basement? A room's length x width x height are used to size purifiers. The largest room size the Coway Airmega 400 should be 492 sq. ft. with an 8 ft. ceiling. This is based on the AHAM 2/3 rule and the Airmega 400's Smoke CADR of 328 CFM running on the highest airf

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

Hi, I created the newest iteration of the Buying Guide. I didn't include the Coway Airmega 300 because in the past, the Coway Airmega 400 would be discounted frequently enough to justify its purchase instead. Annoyingly, there were no good Black Friday or Christmas sales for the Airmega 400 or Airme

In the future, you may want to make a post in this subreddit instead. That would probably yield more views and responses. 😊 Since medium to large is very subjective, it's hard to give exact recommendations. "Cleaning performance" is usually best measured by the Clean Air Delivery Rate (CADR). Higher

The Coway Airmega 400 sounds best for our needs, but I'd like to know from anyone who has one, if the running noise bothered their dogs. I just sent back my Mill food grounds machine because our new rescue dog couldn't stand the noise (which frankly I could barely hear). Our other dog didn't have a

So the second screen capture is the Coway Airmega 400S. The Airmega 400S is the app connected version of the Airmega 400. The Airmega 450: Has higher Clean Air Delivery Rates (CADRs) than the 400/400S Is louder on high (57.7 dBA) than the 400/400S (52 dBA) Uses more energy at 72 W vs. the 400/400S p

So AHAM recommends Clean Air Delivery Rates (CADRs) be a minimum of 2/3 your room's area (assuming an 8 ft. high ceiling). However, if you have allergies or higher-than-normal pollution levels I would choose even higher CADRs. First room needs minimum CADRs of 264 CFM. For this, I would recommend th

Yes. The Coway Airmega 400 sometimes drops in price enough to justify purchasing instead. Last year in the run up to Black Friday, the Airmega 400 was $349. In 2024, I also saw the price around $369 occasionally. Right now, the Airmega 400 is full price. This usually happens before a significant sal
