MERV 11 Filters: This higher efficiency HVAC air filter is recommended if you have severe allergies, multiple pets, or are in a poor air quality environment. It can help you breathe easier and assist alleviating allergies you incur in your residence.
MERV 13 Filters: The highest level of filter efficiency we offer. These Furnace and AC filters capture particles as small as virus carriers, smoke, and bacteria.
