MERV 8, MERV 11, MERV 13 Rating 11.5×11.5×1 Air Filters


The MERV 8 air filters are the energy-efficient and cost-effective way to capture 70% of common airborne contaminants between 3-10 microns in size, keeping your home free of pollen, pet dander, lint, and dust mites while improving the overall air quality of your home.


MERV 11 air filters are an inexpensive upgrade from standard pleated air filters that filter as little as 20% of the particles from the air. Our MERV 11 air filters are designed to effectively capture and block more than 85% of air pollutants in your environment, including pollen, dust, pet dander, lint, mold spores, dirt, debris, smog, and smoke.


MERV 13 air filters offer the highest protection against allergens and have a greater capacity to capture up to 95% of air pollutants in your airstream. These air filters are designed for industrial, commercial, office buildings, and hospitals where superior air filtration is required.
