A clean home will keep you healthy and happy. And, the easiest way to keep your home clean is by regularly using quality air filters. Custom Filters Direct 19.88×21.5×1 air filters help remove dirt and allergens from the air so you can breathe easier. They also keep your heating and cooling systems working efficiently. Each time air passes through these HVAC air filters, they capture more than 90% of allergens and dust particles while allowing the clean air to pass through.

Our air filters are designed with tight mesh weaving that provides a great dust-holding capacity for both residential and commercial environments. Even in a humid environment, these fibers work well to promote indoor air quality.

Manufactured in the USA with the HVAC industry standards in mind, these air filters are guaranteed to deliver exceptional air filtration solutions and long-lasting results than other ordinary air filters available on the market.

Our air filters keep the irritants out while fresh airflow is allowed inside, but the filters become dirtier over time. Dirty and clogged filters result in blocking airflow and decrease the efficiency of the HVAC system. On the other hand, replacing these air filters regularly ensures healthy airflow while improving the efficiency of the unit.
