Carbon Window Air Conditioner Filter 14x48 Cut to Fit by Nordic Pure. Our easy cut to fit sheets also come in activated carbon and can be used in air purifiers, window AC units, or anywhere you want to filter the air. Our hypoallergenic air filter uses permanently electrostatically charged material that acts like a magnet to help dust cling to the a/c filter. This helps protect your unit, home, and family.
The effective life of your air condition filter depends on both the inside and outside conditions in which you live. It is important to regularly change your air conditioner filters especially during any home improvements for fresh, clean air in your home or office. We recommend that you change your window AC air filter every 30 days to maintain maximum efficiency and economy.
