The 3M Filtrete Ultra Clean Air Purifier is available for purchase in two different sizes. One size is suitable for small room and one is best for larger rooms. The Filtrete Ultra Clean Air Purifier claims to be better than HEPA air purifiers at capturing dust and pollen; although, I have not seen any independent research that proves this. The filter will capture mold and pollen as will as debris from dust mites.
The Filtrete Ultra Clean Air Purifier claims to get rid of smoke but I have seen air purifiers that do a much better job. The space range that a Filtrete Ultra Clean Air Purifier can cover is 160 sq. ft. to 360 sq. ft. You will need to purchase additional filters as the Filtrete Ultra Clean Air Purifier does not have a lifetime filter. There are three different speed settings on then Filtrete Ultra Clean Air Purifier.
