Variety of replacement filters for fresh air appliances from low to high performance rated from MERV3 thru HEPA.
MERV13 pleated replacement filters catch pet dander, mold spores, dust and pollen particles as well as larger particles. The pleated design significantly increases the surface area on which airborne particles can be trapped (as compared to MERV6 or MERV8). Great replacement for households with dust and pets. Excellent choice.
