Quest H5 Pre-Filter - MERV 8 (12/Cs)

MERV 8 rated pre-filters are made of 100% synthetic media and can capture common airborne contaminants to include pollen, pet dander, lint, and dust mites. MERV 8 filters can reduce most pollutants, but they are not designed to catch smaller pollutants and allergens that could circulate in the air. MERV 8 filters typically need to be changed every three months.
