The Leader In Air Filtration

Filter Sales was founded as a service organization and today maintains a highly trained service department. Preventive maintenance filter service programs, filter bank repair and upgrades, clean room audits, ductwork video inspections, and IAQ investigations are just a few of our services.

With increasing concern about indoor air quality and reduced maintenance staff, many customers rely on our trained service technicians to supply a filter program that yields accurate system surveys, engineered filter selection and application, optimum service schedules and documentation to support your preventive maintenance program.

Many years ago we recognized the need to raise the industry standard of service and quality to our customers. Our Commitment to Quality set guidelines and performance standards for all employees and departments.

With soaring power prices and new energy directives, it truly pays to save energy in your air filtration systems. Filter Sales knows that saving energy is one of the most challenging tasks facing the HVAC industry today. Keep in mind that energy accounts for up to 70 percent of an air filter's total life cycle cost (LCC), so it always pays for you to choose the best low energy air filter combination for the right filtration application. We'll show you how and we'll prove it in the lab, on your site, or in LCC calculations. Quite simply, we want you to see the positive impact of our low energy air filter products on your bottom line. Filter Sales expertise, products, services and solutions are helping customers to cut operating costs while maintaining high IAQ in their buildings and critical processes.
