Check Your Filter Size

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.

Now that you have found your filter, find it at a location near you and sign up for reminders to change it on time.
