Using one of our harsh environment pre-filters allows you to keep the inside cleaner, avoid extra cleaning and keeps your warranty intact because the inside is kept cleaner. These filters fit on the back of your existing filter just under the back plastic grid that holds the filters in place. These filters are paper-thin, but work just great!
