A fundamental fiberglass filter might not even receive an MPR score since it captures only large debris like lint or hair. On the various other hand, a high-MPR filter can trap points you can not even see, such as pet dander or cooking smoke.

This is different from MERV, which evaluates effectiveness across a wider bit dimension variety (from 0.3 to 10 microns) and includes bigger pollutants like mold spores or textile fibers.
