Which Filtrete™ Filter Best Suits Your Family's Air Quality Needs?
Check out how MPR-rated Filtrete™ Filters outperform MERV standards.
It’s important to know the size of your filter before shopping for a new one. For quick reference, Filtrete Filter dimensions (height x width x depth) are printed on the filter frame, so check there first.
QUICK TIP: The longest side is actually the width based on typical positioning of the filter in a heating and cooling system. You can also measure the filter slot.
Your filter’s MPR (Microparticle Performance Rating) indicates its ability to capture tiny particles between 0.3 and 1 micron in size. The higher the MPR, the more microparticles — such as pollen, pet dander, smoke, bacteria and viruses — your filter will capture from the air passing through it.
