HEPA(High Efficiency Particulate Air Filter)
HEPA, an abbreviation of high efficiency particulate absorption is an effective filtration media for pollutants such as mist, dust and bacteria. The fiber media of HEPA is mainly PP filter paper,glass fiber paper,washable compound filter paper,melt-blown nonwovens and melt-blown glass fiber, and the frame consist of paper,extruded aluminium profiles or plastic.
Features
The filtration efficiency is up to 97%-99.99% for motes of 0.1-0.3pm( The particle caused by smoking is 0.5 diameter). It can realize air purification by removing the dust,pollen,smoke,coal , bacteria,radioactive material and impurity iron.The type and shape of filter medium and filter shall be selected according to the filtering efficiency, ventilation volume, resistance, etc. to adapt to the air purifier.
