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

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

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

Again, I think it's the way the Airmega 400 is designed (albeit counterintuitive). The highest and second highest airflow speeds/settings wouldn't be night mode anyways. The purpose of any night or sleep mode on a purifier is to reduce light output and run on a very quiet speed.

Purifiers aren't good at reducing visible dust and pet hair. Both are large and heavy compared to "invisible" pollutants like PM10, PM2.5, and PM0.1. AHAM's 2/3 rule recommends CADRs be at least 2/3 of your room's area (assuming an 8 ft. ceiling). However, people with allergies or asthma should aim

Per the AHAM 2/3 rule, a 300 sq. ft. space needs a minimum of 200 CFM Clean Air Delivery Rates (CADRs). Since this is also an office, I assume quiet operation is needed too. Therefore you need to "oversize" a bit so you can run the purifier on a lower setting with adequate CADRs. I tend to recommend
