A:AnswerHello Jose, 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.
