ʻO nā mea nui o ka HEPA Air Cleaner

HEPA (High-Efficiency ParticulateKānana ea).Ua hoʻokumu ʻo ʻAmelika Hui Pū ʻIa i kahi hui hoʻomohala kūikawā i ka makahiki 1942 a ua hoʻomohala i kahi mea i hui ʻia o ka fiber lāʻau, asbestos, a me ka pulupulu.Ua hiki i ka 99.96% ka pono kānana, ʻo ia ke ʻano embryonic o ka HEPA o kēia manawa.Ma hope mai, ua kūkulu ʻia ka pepa kānana fiber hybrid a hoʻohana ʻia i ka ʻenehana atomic.Ua hoʻoholo hope loa ʻia ʻo ka mea he trapping efficiency o ka ʻoi aku ma mua o 99.97% no nā ʻāpana 0.3μm, a ua kapa ʻia ʻo ia he kānana HEPA.I kēlā manawa, ua hana ʻia ka mea kānana me ka cellulose, akā ua loaʻa nā pilikia o ke ahi maikaʻi ʻole a me ka hygroscopicity.I loko o ka manawa, ua hoʻohana ʻia ka asbestos ma ke ʻano he mea kānana, akā e hana ia i nā mea carcinogenic, no laila ʻo ka mea kānana o ka kānana kiʻekiʻe o kēia manawa e hoʻokumu ʻia ma ke aniani fiber i kēia manawa.

ULPA (Ultra Low Penetration Air Filter).Me ka hoʻomohala ʻana o nā kaapuni hoʻohui ultra-scale, ua hoʻomohala nā kānaka i kahi kānana maikaʻi loa no nā ʻāpana 0.1μm (ʻo DOP mau ke kumu lepo), a ʻoi aku ka maikaʻi o kāna kānana ma mua o 99.99995%.Ua kapa ʻia ʻo ia he kānana ULPA.Hoʻohālikelike ʻia me HEPA, ʻoi aku ka paʻakikī o ka ULPA a me ka ʻoi aku ka maikaʻi o ka kānana.Hoʻohana nui ʻia ʻo ULPA i ka ʻoihana uila no ka manawa, a ʻaʻohe hōʻike o nā noi ma kanā lāʻau lapaʻau a me nā lāʻau lapaʻau.
