Cuckoo - CAC-IO510FW

Don't hate on Cuckoo - it is a very reputable S. Korean brand. They make the best high-tech rice cookers around! Their air purifier units have been around for years, so they are a reliable brand. I have the Cuckoo from Costco and it has been great for dorm use. I originally wanted the Winix C610 but for some strange reason that particular Costco would not ship to the warehouse, and Costco refused to deliver to my college! It is super quiet, quieter than the piece of garbage and overpriced Dyson that is acting all weird after 8 months of use. The Cuckoo sensor is not as good as the Dyson or the Winex 5500. So, you will have to cycle it manually once in a while. Once you do that, it works well in sensing when the room air is clean. I can only assume that it has a poorly placed sensor or a bad algorithm when compared to the others that are 3 to 5 times the price.

Cuckoo is even better than coway

"max" usually means one air change an hour. The product numbers don't match each other. Top says up to 228 in 30 minutes, which would imply 456 sqft in 60 minutes, but later it says only 384. And in between we have 3 different CADR numbers. The smoke one does match 384 sqft in one hour. $99 for 50 CFM is a poor price, even if it comes with a replacement filter.
