Sun Air Filter cleans filters used in most every commercial/industrial application. Ours is a one-of-a-kind proprietary system designed and built by those who use it. We have been in business for over 26 years. Many of our customers have been with us that entire time. This is not a “now you see ‘em, now you don’t” franchise system. We treat every filter as our own and every customer as a friend. Many organizations are unaware that filters can be safely cleaned with no loss of air flow or efficiency. Independent laboratory tests confirm that air filters can be cleaned multiple times without any loss in air filter effectiveness.
