Product Description:

Captures: 90% of large allergens - like mold spores and pet dander - from the air passing through the filter; microscopic allergens like dust, smoke and smog particles; and bacteria and particles that can carry viruses. No unnecessary antimicrobial chemicals added. Filtrete filtering material will not support the growth of bacteria, mold, mildew or fungi in normal use.

Rating : - Could not Find it at any Local Store
I have been looking for a good filter for a long time and I could not locate this brand of filter in my size at any of my local ACE Hardware, Lowes or Home Depot Store. I purchased a 4 filter pak and I am only on my first filter, and the filter states it is suppose to help control dust and allergies but at this time I really do not know how much better it has been performing vs the cheaper filters I had been using. I guess once I change the filter in 2 1/2 months I may be able to see how much dust etc had been trapped in the filter.
