Filtrete Air Filters

Filtrete air filters are often praised for their allergy-friendly filtration. At Factory Direct Filters, we ensure the same quality with our aftermarket alternatives. Whether your HVAC unit requires a standard 16x25x1 Filtrete, a less common 20x25x1 Filtrete, or any size in between, we have what you need to keep your home's air fresh and relatively allergen-free. Enjoy free shipping with your order in addition to our price match guarantee. Your family, and your health, will thank you for the cleaner, more breathable air when you replace your Filtrete furnace filter.
