When it comes to air filters for HVAC systems, Custom Filters Direct 13x20x1A air filters are the best filters available on the market. These air filters are a cost-effective way to promote better airflow throughout your home or office. Our air filters are electrostatically charged and built to capture all types of bacteria and viruses that can fester within your indoor air for days.

Ideal for those who suffer from seasonal allergies or breathing problems, 13x20x1A filters are a more powerful tool for ensuring that the incoming airflow is clean before entering your home or workspace.

Custom Filters Direct 13x20x1A are designed to constantly capture the dirt particles until their tight mesh weaving gets clogged over time. Once the filters get clogged, they don’t filter the air properly and result in a lack of clean airflow in your space. That’s why we suggest you change your air filters every 60-90 days to maintain healthy indoor air quality.
