HEPA air filters are the leading types of filters on air purifiers today and the technology continues to evolve. In 1963, two German brothers Manfred and Klaus Hammes invented the first air purification system for home use, which boosted the quality of air in residences in Germany. Click to see full answer.
HEPA Filters History. HEPA filter technology was first designed and created in the 1940s by the US Army Chemical Corps and National Defense Research Committee. As part of the Manhattan Project, scientists were required to develop a filter suitable for removing radioactive materials from the air.
The first HEPA filter (high efficiency particulate air) was designed in the 1940's by the research and development firm Arthur D. Little under a classified government contract as part of the Manh attan Project, where the first atomic bomb was developed during World War II.
A HEPA bag filter can be used in conjunction with a pre-filter (usually carbon-activated) to extend the usage life of the more expensive HEPA filter. In such setup, the first stage in the filtration process is made up of a pre-filter which removes most of the larger dust, hair , PM10 and pollen particles from the air.
There are cheap foreign made filters that claim to be HEPA that are not so always be aware of these cheap imitations. HEPA type filters are not actually new technology and have actually been around for along time. They were developed in the 1940’s as a way to filter radioactive particles during work on the Manhattan project. The technology of HEPA filters was considered classified until after WWII was over.
These are just a few examples of many patented inventions that feature HEPA filters: GB Patent 495,320A: Improvements relating to filters by Cecil Gordon Vokes, November 7, 1938. US Patent 3,246,457: Pleated Air Filter Cartridge by Kenneth W. De Baun, Farr Company, April 19, 1966. US Patent ...
High efficiency particulate air filters (HEPA) were actually developed to protect soldiers and scientists from the radioactive particles that were expected to be created from atomic bombs. 1.800.880.4808
In the 1950’s during WWII, HEPA filters were invented by the US Atomic Energy Commission (AEC), who needed something that would remove small radioactive dust particulates from the air. In the last decade HEPA-technology air purifiers have been used to clean indoor spaces from homes to beauty salons to hospitals and operating rooms across the country.
The first residential HEPA filter was reportedly sold in 1963 by brothers Manfred and Klaus Hammes in Germany, who created the Incen Air Corporation which was the precursor to the IQAir corporation. [ citation needed ]

Better air filter than hepa?
High-efficiency particulate air (HEPA) filters are a type of mechanical air filter that works by forcing air through a dense web of fibers or fine mesh to trap tiny, harmful particles. HEPA is a standard initially developed by the U.S. Department of Energy during the 1940s to protect people from contaminants that resulted from nuclear testing.
Can true hepa filter coronavirus?
Air purifiers with HEPA filtration efficiently capture particles the size of (and far smaller than) the virus that causes COVID-19, so the answer is yes… Many media outlets have incorrectly stated that HEPA filters don't filter below 0.3 micron and therefore could not capture airborne coronaviruses.
Does hepa filter remove mold?
While an air purifier cannot remove mold from a surface once it begins to grow, using an air purifier with a true HEPA filter is a crucial part of removing mold spores from the air.
Is a hepa filter charcoal?
Because HEPA filters cannot remove gases, VOCs and odors that are typically 0.3 microns and smaller, activated Charcoal air filters are used in air purifiers to serve the purposes that HEPA filter cannot filter… In fact, activated Charcoal is so effective that it is used to combat the harmful airborne pollutants.
Is a hepa filter necessary?

What is hepa filter efficiency?
Now when you know the sizes of pores and understand the meaning of the term ‘efficiency’, you can understand that the efficiency of a HEPA filter increases as the filter gets dirty. This simply means that fewer and fewer particles will be able to pass through it.
What is true hepa filter?

What makes a hepa filter?
HEPA filters are high efficiency filters that typically capture over 99.5% of all particulate pollution. They're made from either plastic (PP+PET) or fiberglass, and can capture things like pollen, viruses, bacteria, mold and PM2. 5. Diffusion also means they are highly effective at capturing nanoparticles too.
