What is HEPA filter? Posted on  十二月 24, 2018   by  olans228 High efficiency particulate air (HEPA),originally called high-efficiency particulate absorber but also sometimes called high-efficiency particulate arresting or high-efficiency particulate arrestance, is a type of air filter. Filters meeting the HEPA standard have many applications, including use in clean rooms for IC fabrication, medical facilities, automobiles, aircraft and homes. To qualify as HEPA by industry standards, an air filter must remove (from the air that passes through) 99.97% of particles that have a size greater-than-or-equal-to 0.3 μm. HEPA was commercialized in the 1950s, and the original term became a registered trademark and later a generic term for highly efficient filters. HEPA filters, as defined by the United States Department of Energy (DOE) standard adopted by most American industries, remove at least 99.97% of airborne particles 0.3 micrometers (μm) in diameter. The filter’s minim...

What is PM2.5? what is the harmful? PM2.5 refers to particulates with a diameter less than or equal to 2.5 microns in the atmosphere, also known as particulates that can enter the lungs. It is rich in a large number of toxic and hazardous substances and has a long residence time in the atmosphere and a long transportation distance. Therefore, it is important for human health and The impact of atmospheric environmental quality is even greater. Studies have shown that for every 10 micrograms/cubic meter of PM2.5 daily average, the risk of death from respiratory disease increases by 0.97%, the risk of death from cardiovascular disease increases to 1.22%, and the rate of death from heart and lung disease and cancer Mortality rates increased by 6% and 8%, respectively. PM2.5 is the critical value to reach the alveoli. PM2.5 fine particles, the upper respiratory tract can not stop, they can all the way down, into the bronchioles, alveoli. Our respiratory system is like a plant root. From...
