Using your Westinghouse WRJ600 Series rangehood filters is easy. Just place them in your rangehood according to the manufacturer's instructions. Remember to regularly check the filters to see if they need cleaning. To clean, remove them from the rangehood and soak in warm, soapy water. Gently scrub with a soft brush to remove any grease or dirt, then rinse thoroughly and let them dry completely before putting them back in. Also, make sure to turn off the rangehood before removing or installing the filters for safety. With proper use and maintenance, these filters will keep your rangehood working well for a long time.
