Filtrete MERV 13 Ultimate Allergen Air Filter – HVAC Furnace Filter – Fast Ship

Match the replacement filter to the exact nominal dimensions specified for your HVAC equipment or existing filter. Confirm length, width, thickness and required MERV rating before ordering. Do not substitute a different size solely because it appears close.

MERV is a filtration-efficiency rating. Higher MERV ratings generally capture smaller airborne particles, but the correct filter must also be appropriate for the airflow requirements of your HVAC system. Follow the equipment manufacturer's filter and airflow requirements.
