Window Air Conditioner Filter, 15x24x.25-in.

The Frost King F1524 is a washable, reusable foam air-conditioner filter designed to fit standard 15×24-inch window AC units. This polypropylene foam filter removes dust, pollen, and airborne particles from your home's cooling system, helping maintain cleaner indoor air and supporting efficient cooling performance throughout the warm months.

Unlike disposable filters that require frequent replacement, this washable filter can be rinsed clean, air-dried, and reinstalled multiple times, saving money on replacements and reducing landfill waste. The flexible foam construction allows you to trim the material with ordinary scissors to fit irregular window frames or custom dimensions, ensuring a secure seal in virtually any AC unit.
