3 Blueair 500/600 Series Air Purifier Filters
very good deal
Very good value. Just wish the edges were black instead of white. Other than that, the filters appear to be comparable to mfg product
Pleasantly surprised to find that these look exactly like the original blue air filters I've been spending $80 on every six months. Won't hesitate to recorder these.
Seem to be a good replacement filter. The only negative is you can see the white edge when installed. Probably use a black marker or black tape to hide it from being visible. $20 dollar savings from original filter
but would certainly say they're fine and a good choice
These filters appear to be equal in quality to the more expensive ones we've purchased in the past. I have no way to scientifically compare them, but would certainly say they're fine and a good choice.
