HEPA Filter

The HEPA Filter (also called high-efficiency particulate air filters) are top of the line air purifiers. These HVAC filters remove more than 99% of particles that are 0.3 microns or larger in size. Using a HEPA filter can remove most airborne particles and pollen that can make allergies worse.

ISC has air filters for industrial and consumer applications that will produce clean, safe air. HEPA filters create the cleanest air possible at the highest level of efficiency while eliminating potential air leaks. Proper air filtration and care for your HVAC system will result in increased air quality for building occupants and will increase the efficiency and longevity of your entire HVAC system.
