Did you know? HEPA filters were first created in the 1940s to combat airborne radioactive contaminants during wartime. HEPA filters come from an interesting background. That’s about 300 times smaller than a strand of human hair. A true HEPA filter can remove at least 99.97% of particles 0.3-micron in size from the air. From vacuum cleaners to air purifiers and even airplanes and motor vehicles, they are a powerful barrier between airborne pollutants and our delicate lungs. High Efficiency Particulate Air filters (HEPA filters for short) are everywhere today.
