Positive Customer Reviews

The automatic mode is great.  As soon as an odor is detected, this unit will automatically display an odor light and the fan will speed up to remove the odor.  Works great for pet hair also.
-- R.C.

Quiet and powerful. Since purchasing this air cleaner we no longer see any floating dust and it does a great job removing pet odors. Our son has allergies and we purchased this unit for the living room after seeing how well the 9000S (smaller unit) worked in his room.
-- C.F.

A great feature of the 9000 is that, unlike other air purifiers, it blows air straight up. This allows for it to be placed against a wall and reduces "breezes".

Negative Customer Comments

Doesn't seem to work for us unless it's set at the highest setting. Unfortunately, at this speed the unit is extremely loud and almost unusable in our living room.
