A:Answer Hello! For model WMH32519HB, Whirlpool® Microwave, Grease filters: Grease filters are on the underside of microwave oven. Clean monthly or as prompted by Filter Status indicator. Slide the filter away from the tab area, and drop out the filter. To reinstall, place end of the filter into the opening opposite the tab area, swing up the other end, and slide it toward the tab area. Charcoal filter: The charcoal filter is behind the vent grille at the top front of the microwave oven. The charcoal filter cannot be cleaned and should be replaced about every 6 months. Remove 2 screws on the vent grille, slide the vent grille to the left, tilt it forward, lift it out, and remove the filter. To reinstall, place the filter into its 2-hook area with the wire mesh side to the front. Replace the vent grille by inserting the 3 bottom latch hooks of the vent grille into the front holes, tilt the vent grille
backwards, slide it to the right, and secure with screws.
