Using this Westinghouse rangehood filter is easy. First, make sure your rangehood is turned off and unplugged for safety. Locate the old filter in your 600mm wide canopy type Westinghouse rangehood and carefully remove it. Then, place the new filter in the same position as the old one. Ensure it fits snugly. When it comes to cleaning, it's a good idea to clean the filter every few weeks. You can soak it in warm, soapy water for about 30 minutes, then gently scrub it with a soft brush to remove grease and dirt. Rinse it thoroughly and let it dry completely before putting it back in the rangehood. If your model number is not listed in the product description, don't buy it without checking with us first.
