Is this filter made for in house circulation? Also, how do you install this filter?
Answer Morris, when using the microwave to recirculate in the home you will need to add a charcoal filter, part number WB02X10943. Here is the link to your owners manual, refer to page 29 for removal and installation instructions for the charcoal filter.
