PRODUCT FAQ
-
How often should I replace the Filtrete™ 1900 MPR UA03-4 filter?
We recommend replacing this filter every 90 days under normal household conditions, though you may need to change it more frequently if you have pets, allergies, or live in a dusty environment. Simply check your filter monthly—if it looks noticeably dirty, go ahead and replace it sooner.

What makes the 1900 MPR rating different from lower-rated filters?
The 1900 MPR (Microparticle Performance Rating) means this filter captures smaller particles more effectively than standard filters. It's specifically designed to trap allergens, viruses, and air pollutants, making it an excellent choice if you're concerned about indoor air quality or have respiratory sensitivities.

Will this filter fit my furnace or air handler?
The UA03-4 measures 20 x 25 x 1 inches, which is a standard residential size. Before ordering, please check your current filter dimensions or your HVAC system's specifications to ensure compatibility. If you're unsure, I'm happy to help you verify the right size for your system.
