Noisy
Put this in our en suite and it is so noisy we have to unplug it before we go to sleep.  Moved it to another room.  For the price point I thought it would quietly do its job.  It seems to work, but it is not the only one... I have air purifiers throughout the house since we have long Winters  and house is closed up.  Got this one for its compact size.  Would not buy again b/c of the noise.
