It is stored in a compartment behind the front intake grille. See item 7 on page 5 for location. The HEPA filter should last approximately 12 months with continuous use, less in areas with a high level of airborne particles such as dust or pollen. The carbon pre-filter will last approximately three months. NOTE: You must reinstall and snap the intake grille before checking the filters with the gauge. The air purifier will not operate if the grille is not in place. 1 Insert either end of the filter check gauge into the recessed hole on the top of outlet grille. Turn the fan on QuickClean.™ 2 Filter(s) OK The colored cylinder should float up the filter check gauge. If it does not move from the bottom of the gauge, the filter(s) are clogged and need to be replaced. Replace Filter(s) 13
