Clean Air HEPA Pleated Pre-Filter - 19-in x 15-in x 0.45-in - 2-Pack

Nothing's better than these Vent Guard replacement baseboard grille filters to get rid of household dust, dander, pollen, carpet fibres, pet hair, and dust mites. They're easy to replace since they're disposable. Protected by a limited warranty, these replacement filters will make you save time because they're made to fit. You'll never need to cut or mount them. For optimal performance, it's recommended to change each filter at least every 90 days, because a dirty filter will slow down airflow and make the system work harder to keep you warm or cool, resulting in energy waste. Use these filters to keep heating system return ducts clean and extend the life of your main furnace filter. This model measures 14 inches x 8 inches x 0.45 inches.
