Extra Large Washable AC Window Unit Pre-Filter, Carbon Pad Purifier

Cut to Fit Replacement Filters

Sizes Available We offer two larger sizes of air conditioner replacement filters: 15.7" x 27.6" and 15.7" x 59". The larger size allows for more efficient cutting and custom fitting to various air conditioners and purifiers.

Experience Cleaner Air

Efficient Particle Capture Our cut-to-fit foam pad pre-filter excels at capturing large particles like hair, dust, pet hair, lint, smoke, and VOCs. This ensures fresh, breathable air and a safer environment for pets, kids, and families.

High-Quality Filtration

Thick, Durable Design Unlike other ultra-thin filters, our window air conditioner filters measure 5/16 inches thick. This thickness effectively blocks large particles and enhances the filtration process. After use, you can clean and reuse the filter to extend its service life.

Versatile Compatibility

Compatible with Various Devices Our air conditioner foam filter is designed to fit various appliances, including air purifiers, range hood filters, humidifiers, vents, and computer mainframe fans. The cuttable design ensures it can be adapted to a wide range of electrical appliances.

Important Notes

Vacuum Sealed Packaging Since our filters are vacuum packaged, we recommend leaving the foam pad pre-filter unassembled for 2-3 days after unpacking to allow it to fully rebound.

Regular Carbon Filter Replacement For best results, we recommend replacing the carbon filter every 1 to 2 months to maintain optimal air purification.
