Cleaned and reused for years — not thrown away
Airsan washable air filters are permanent metal filters engineered to be cleaned and reused for years instead of thrown away. Every Airsan metal filter is, by design, a washable air filter — rinse it, recharge it, reinstall it. Switching from disposable filters eliminates recurring filter spend and waste while keeping airflow and protection consistent.

What is a washable air filter?
A washable (or reusable) air filter is built from durable media — typically aluminum, galvanized, or stainless steel mesh — that can be cleaned and put back into service rather than discarded after one cycle. Unlike disposable fiberglass or paper panels, a permanent metal washable filter holds up to repeated cleaning, which is why it’s the standard choice for commercial HVAC, industrial intakes, and demanding marine and power applications.
Washable by design for 80+ years
Airsan has manufactured permanent, washable metal air filters for over 80 years. The same construction that makes our filters durable also makes them fully reusable: clean the media, re-coat it with Film-Cor recharging adhesive, and the filter performs like new.
