๐๐ข๐ ๐ฒ๐จ๐ฎ ๐ค๐ง๐จ๐ฐ? HEPA filter technology was first designed and created in the 1940s by the US Army Chemical Corps and National Defense Research Committee.
๐จ Researchers needed a way to control very small particles which had become contaminated by nuclear radioactive sources.
๐ The filter design itself was based on gas masks worn by U.S. Soldiers fighting in the war. These gas masks were developed to contain a special type of complex paper made from asbestos and cellulose fibres that filtered out airborne toxins, keeping the soldiers safe during gas attacks.
๐ฅผ Post-war, HEPA technology was declassified after World War II and became available for commercial and residential use. Their use in medical, industrial, and pharmaceutical industries was apparent, and they began to be adopted across industries where there are harmful particles being released into the air. HEPA filters played a key role in the research and development of modern pharmaceuticals, aerospace engineering, and computer chip manufacturing.
๐จ Since the 1950s, their use has expanded to include mold remediation, asbestos cleanup, lead cleaning, chemical cleaning, home air filters, office filters, and more.

HEPA filters, or High Efficiency Particulate Air filters, are some of the most popular air filters on the market for homes, businesses, and custom use. They are required to filter a minimum of 99.97% of particles down to 0.3 microns to be considered True HEPA, although many industrial and custom HEP...
