high efficiency particulate air (hepa) filter for Dummies

“HEPA” means “high-efficiency particulate air” (filter). It sounds challenging, but HEPA air filters are nothing extravagant. They had been invented again in the forties when experts were producing the atomic bomb, and so they’re just a mat of randomly aligned fibers, comprised of either glass or synthetic products. The synthetic substance Employed in the air filter is comparable to what’s Utilized in fast-dry T-shirts.

The compact particles are successfully blown or bounced all around and collide with the filter media fibers.

Big particles resist change in path and try to continue within their first course because of their inertia, this triggers them to collide with and connect on the fibers.
