High-efficiency particulate arrestance is referred to as HEPA particulate filter. People often call it HEPA filter or air filter. HEPA filters that meet the standard are widely used in facilities, cars, airplanes and Home products. HEPA standards are set by the DOE Department of Energy: the filtration efficiency for dust particles of 0.3 microns must reach more than 99.97%. The filter that plays the role of filtering is hepa filter paper.
Most air purifiers and fresh air purifiers on the market currently use HEPA filters, but they are also called HEPA filters But they have different purification effects. Purification level and production materials are both decisive factors, and users must check the product when purchasing. HEPA filters can be divided into PP filter paper, composite PET filter paper, melt-blown, polyester non-woven melt-blown, glass fiber and other materials according to type. Among these materials, hepa filter paper made of ptfe material stands out among many materials with its own advantages. Let’s take a look at it together.
PTFE filter membrane material has a fibrillar microporous structure, the porosity can reach more than 85%, there are 1.4 billion micropores per square centimeter, and the pore diameter range is Between 0.02um and 1.5um, the filtration precision of hepa filter paper can reach U15~U17 level, which can capture most dust particles so that dust cannot enter the membrane through the surface of the membrane. The unique three-dimensional network structure makes it impossible for dust to pass through.
It is obtained by thermally compounding the independently developed PTFE microporous film and imported non-woven fabric Hepa filter paperhas a reliable filtration grade of H13-U16, low wind resistance and low energy consumption. It can be widely used in semiconductor, electronics, flat panel display, photovoltaic and other industries. We have a complete pre-sales, sales and after-sales service system.
