About HEPA Air Filtration
Research Studies and Facts
HEPA air filters are largely considered the most effective type of air filter for solid particles, such as dust and other allergens.
HEPA air filters are made from very tiny glass fibers that are made into a tightly woven paper. This creates a filter consisting of a multitude of very small sieves that can capture extremely small particles, including some biological agents. Once trapped, contaminates and particles are not able to flow back into circulation, due to the highly absorbent pores of the HEPA air filter.
HEPA air filters were developed by the Atomic Energy Commission during the second World War. They were originally designed to remove radio active dust from their plants.
Journal of Hygiene study found that ionizers increase efficiency of HEPA air filters. The Multi-Tech offers an ionizer in addition to its True HEPA filter.
A study by Air & Waste Management Association found the combination of a HEPA air filter and germicidal UV lamp reduced bacteria by 80% in a 3072 cubic foot chamber.
