PRODUCT FAQ
-
What does the 1550 MPR rating mean?
MPR stands for Microparticle Performance Rating. A 1550 MPR means this filter captures 1550+ microparticles, making it one of our highest-performing filters for trapping allergens, bacteria, and viruses from your home's air.
-
How often should I replace this filter?
We recommend replacing your Filtrete filter every 90 days under normal household conditions. However, if you have pets, allergies, or live in a dusty area, you may want to check it monthly and replace it sooner if it looks visibly dirty.
-
Will this filter fit my furnace or air handler?
This filter is designed for standard 20 x 20 x 4 inch HVAC systems. Before purchasing, please measure your current filter or check your system's specifications to ensure compatibility. If your system uses a different size, we have other Filtrete options available.
-
Does this filter reduce odors as well as particles?
This filter is primarily designed to capture microparticles like allergens, bacteria, and viruses. While it can capture some odor-causing particles, if odor control is a priority, you may want to consider our Filtrete Odor Reduction filters as an alternative.
-
Is this filter effective against COVID-19 and other viruses?
Our Filtrete Allergens, Bacteria & Viruses filter is designed to capture airborne particles as small as 0.3 microns, which includes many common viruses. However, it's most effective as part of a comprehensive approach that includes proper HVAC maintenance and other preventive measures recommended by health authorities.
