This filter removes 99.95%+ of microns .5 or greater in size and has a thin layer of charcoal to remove unwanted odors from the air. Although not as efficient as the HA-50 HEPA filter it still does a great job at removing odors and dust from blow back into your home.

Miele has recommended changing once a year for standard user volumes (or approx. 50hrs of use). A tab has been added to help users track the life of the filter and maintain optimal performance
