Filterbuy's 12x15x1 MERV 11 pleated air filter is the best product for those who want advanced indoor air quality without losing HVAC efficiency. This filter is highly efficient in the range of 95% of airborne particles—which mainly are dust mites, pet dander, mold spores, pollen, and smoke—that it is able to remove from the air, and thus the filter creates a very powerful barrier to common allergens and irritants.
