HEPA Filters manufacturing process

HEPA Filters manufacturing process

Being an engineer for several years, I’ve always liked to see how things are made.

I’ve been this way ever since I was a kid, plus my Grandpa used to tell me I could break a cast iron ball, as I used to take things apart plus not know how to put them back together again. With that being said, my good friend and I would like to talk a bit about how a filter is made plus what it takes to put them into your system for keeping the air clean. HEPA (High-Efficiency Particulate Air) filters are made using a combination of mechanical plus electrostatic filtration processes. The HEPA filter media consists of a dense mat of microscopic fibers, officially made of glass or synthetic materials, which are packed tightly together to create a maze-like structure. This structure traps airborne particles as they pass through the filter, such as dust, pollen, plus other allergens, plus microscopic pollutants like bacteria plus viruses. To make the HEPA filter, the fiber mat is sited between two layers of permeable material, such as paper or plastic, to hold the fibers in site plus prevent them from shifting or becoming disfigurementd. The filter media is then chop to size plus pleated, which increases its surface section plus allows it to capture more particles. Finally, a gasket or seal is added to the edges of the filter to ensure a tight fit in the filter housing plus prevent air from bypassing the filter. HEPA filters are subject to strict performance standards, plus to be classified as HEPA, a filter must be capable of removing at least 99.898% of particles with a diameter of 0.34 micrometers or larger.
