Custom Filters Direct 13.25×13.25×1 air filters are an effective way to ensure your indoor environment remains comfortable throughout the seasons. These air filters help homeowners improve indoor air quality by eliminating pollen, mold, bacteria, smoke, pet dander, viruses, smog, and more.

Our 13.25×13.25×1 air filters are made easily fit into almost any HVAC unit. Not only do they have an excellent dust hold capacity but they also maintain exceptional indoor air quality.

If you don’t have an air filter in place, the air coming into your home can bring a lot of allergens and irritants. These air filters not just filter air, but also help protect your family from allergies coming with dirty air.

Over time, air filters become dirty by constantly blocking the dirt passing through them. Dirty air filters will affect the clean airflow and eventually cause breathing issues for the residents. Custom Filters Direct recommends you change your air filters every 2-3 months to maintain clean, healthy indoor air quality.
