Metal mesh filters

Dustless Air Filter Co. will custom manufacture the metal mesh filter you require. Filters are made of aluminum or stainless steel. Each filter is produced with heavy duty materials and built to exact dimensions.

Range hood filters can become coated with a greasy build-up that is difficult, if not impossible, to clean. They should be replaced periodically to keep your range hood operating efficiently and to minimize any fire hazard from grease build-up.
