Fan noise
It appears to be well made. My VOCs still register high after hours of use though. Maybe a thicker carbon filter would help. This is more a BlueAir issue, but after installing this, the fan rattles and makes noise on fan speeds 2 and 3. At that point, it’s a noise generator.My BlueAir started making noise by just adding a thin carbon panel to the original Blue Air filter.

Fits perfectly well.
I was worried about the machine rejecting this replacement as many devices do if you don't buy their exclusive parts. Not the case, so, all that remains is to see if it does the job and for how long. I know the original worked because the A/C filter lasted for 3 months like new.

Same same
These seem to be identical to the original manufacturer ones.

What's not to like
Fits Perfectly, Great Price, My only issue is installation.Blueair recommends to install with carbon facing in, whereas this manufacturer shows carbon facing out.Confusing...
