15×24 Window Air Conditioner Unit Filter by Nordic Pure. Our cut-to-fit sheet can be used in air purifiers, window AC units, or anywhere you want to filter the air. 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. The window AC unit filter traps dust, pollen, dander, and other common pollutants in the air, improving air quality in your home or office. 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 air filter every 30 days to maintain maximum efficiency and economy.
