HEPA fliter
風速 : 每秒 0.45m ( 100+-20%fpm )
濾網可過濾 99.997% 0.3um以上的顆粒 (無法滅菌)
過濾速度 : >75fpm
換氣次數 : 25-35次/hr
壓力差 : 130-490 Pa ( >490要換 )
空氣品質 : DOP(Dioctylphthalate) 、PAO(Poly-alpha-olefin) 作為HEPA洩漏試驗用煙霧劑 每6個月 監測一次

HEPA is a type of pleated mechanical air filter. It is an acronym for "high efficiency particulate air " (as officially defined by the U.S. Dept. of Energy). This type of air filter can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm).
