Rating : - BEWARE OF HORRIFIC MESS!!!
I am a very careful shopper, and meticulously care for my property. This air cleaner was purchased on the recommendation of Consumer Reports.

The air cleaner would work well for awhile, but then I would notice BLACK FLECKS all over the walls, ceiling, windows, throughout the air cleaner ...... everywhere throughout the room!!!!!

This mess is caused by the replaceable "carbon filter" at the back of the air cleaner, and the mess DOES NOT clean up with soap and water - a heavy cleaning agent is required!!!!!

After the 4th mess throughout the family room, and numerous replacements of the "carbon filter" (one $24.00 filter lasting a whole 2 weeks before it spewed all over the walls and the air cleaner itself), I ordered a "pre-cleaning filter" to replace the "carbon filter", but the air cleaner no longer turned on. I believe too much BLACK GUNK from the carbon filter had ruined the air cleaner - and there is no way to take the air cleaner apart to clean the inside.

I made contact with the company for help with the problem. They merely guessed at what might have happened and offered no solutions.

After only 2 years this $500.00 air cleaner (not including the numerous replaceable "carbon filters") now rests in a land fill!!!
