AirFanta 3Pro vs Winix 5500-2

“This was a mixup actually - the beef this sub has is with the CleanAirKit creator. We've redacted all the criticisms of the maker of Airfanta (or are in the process of doing so). The fact remains that it has no certification, no unbiased reviews, and seems to be marketed entirely by astroturfing.”

“>The combination of those spaces is definitely less than 1,740 sq ft, which it says i can clean in an hour, 1,740 sq ft is marketing nonsense. Usually it means 1 or 2 air changes per hour (ACH)--far below the recommended 4.8 ACH (and even 4.8 ACH is too low according to many air quality scientists). 1 or 2 ACH will do nothing for you. Yes, all manufacturers' CADR claims and AHAM certified CADRs are based on the air purifier's highest setting. Winix says its 5500-2 is AHAM Verifide^(®) at 360 sq ft. For any room larger than 360 sq ft, you'll need more than one 5500-2. It's *usually* better to get a couple or a few smaller, cost effective air purifiers and place them in various areas, than getting 1 big one--mostly because of air dynamics. I would get a couple or a few of the 5500-2 (I have the 5500-2) or mix and match with another similar quality brand. >I will give props to medify, because they show the CADR for each setting, so maybe the thing to do is bail on winix all together and only go with a company that actually shows realistic CADR?? Yep, Medify is rare for showing CADR at different settings (AirFanta does also), but I wouldn't pick a Medify over the Winix 5500-2 just because it discloses CADR at each setting. E.g., the Medify MA-40's top CADR is the same as the 5500-2's, but the MA-40 is $100 more expensive and is known to be loud. If money is no object, the MA-50 and MA-112 are decent choices.”
