When talking about True HEPA (real high efficiency), we have to talk about: What is the filtration efficiency of the air purifier filter? Many people will say, “The filtration level of the filter I use is H13.” So what are the criteria for judging H13?
According to the EU EN1882 standard, a filter with a filtration efficiency higher than 99.97% for 0.3μm particles is called H13. Judging from current domestic statistics, the purification efficiency of domestic air purification products is still 90%~95%@0.3μm, which is at best a sub-high-efficiency filter.
The filters in the entire purification system include formaldehyde removal filters, deodorizing filters, dust collection filters and HEPA filters. Among them, the HEPA filter is composed of HEPA high-efficiency filter paper, which is continuously folded back and forth to form a wavy gasket. Due to its small pore size, micro particles cannot pass through. It has a large adsorption capacity and is purifying It is highly efficient and has features such as water absorption. HEPA can be divided into five materials: PP filter paper, glass fiber, composite PP PET filter paper, melt-blown polyester non-woven fabric and melt-blown glass fiber.
HEPA high-efficiency filter paper is a new type of filter material formed by compounding a layer of PTFE film on the surface of ordinary filter material. It has excellent breathability, corrosion resistance, aging resistance, temperature resistance and other properties. According to the usage requirements, the pore diameter can be between 0.1-10um, the thickness can be between 2-100um, the porosity can reach 50%–80%, there are up to hundreds of millions of micropores per square centimeter, and the filtration grade can reach H13-U16. It can operate at a continuous operating temperature of 240°C and an instantaneous temperature of 260°C.
