Which Filtrete™ Filter Best Suits Your Family's Air Quality Needs?

Every home and family is different. From allergens to pets to climates you live in, a variety of factors should influence your air filter purchasing decision. Use our guide to help find the best Filtrete™ Filter for your home.

Which filter fits your needs?

Check Your Filter Size

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.

At least – now that you’ve selected your filter, find it at a location near you and sign up for reminders to change it every three months.
