ʻO ka kānana HEPA ka kānana nui i hoʻohana ʻia i ka hapa nui o nā mea hoʻomaʻemaʻe ea. Hoʻohana nui ʻia ia e kānana i nā ʻāpana molekala liʻiliʻi i ka lepo a me nā mea paʻa i hoʻopaʻa ʻia me ke anawaena o ʻoi aku ma mua o 0.3μm. ʻO ke kumu kūʻai o nā kānana HEPA ma ka mākeke he nui loa. Ma waho aʻe o nā kumu kumu kūʻai o nā huahana ponoʻī, aia kekahi pilina me ke kiʻekiʻe o nā kānana HEPA.
Hoʻokaʻawale ʻia nā kānana HEPA a me nā mea like i G1-G4, F5-F9, H10-H14 a me U15-U17 e like me ka pae ʻEulopa o kēia manawa. ʻO ke ʻano maʻamau o ka mea hoʻomaʻemaʻe ea ʻo ka H grade, kahi kānana kūpono a i ʻole sub-efficient. ʻIke ʻia ka H13 ʻo ia ka kānana H13-14 maikaʻi loa. Hiki i ka kānana HEPA o ka papa H13 ke hoʻokō i ka pono holoʻokoʻa o 99.95%. Hiki ke hiki i ka 99.995% ka nui o ka pono o ka kānana HEPA papa H14.
ʻOiaʻiʻo, ʻo ka pae hoʻomaʻemaʻe kiʻekiʻe loa o ka kānana HEPA ma ka maʻamau ʻEulopa ʻo ia ka papa U, a ʻo ka U-17 papa HEPA kānana maikaʻi loa he 99.999997%. Eia nō naʻe, no ka mea ʻoi aku ka uku o ka kānana HEPA U-grade i ka hana ʻana, koi nui ia i ka ʻenehana hana. No laila ʻaʻole nui nā noi ma ka mākeke.
Ma waho aʻe o ka papa hoʻomaʻemaʻe, ʻo ka kānana HEPA he helu ahi. Hoʻokaʻawale ka mākeke i ʻekolu mau māka e like me kona degere o ke ahi kū'ē: ʻo ka mīkini HEPA mua, ʻo nā mea a pau o ka mesh HEPA ʻaʻole hiki ke hoʻopau ʻia, a ʻo nā mea hiki ʻole ke hoʻopau ʻia e kūlike me GB8624- 1997 Class A; ʻO ka pūnaewele HEPA lua, pono ʻole ka HEPA mesh kānana mea me GB8624-1997 Papa A ʻaʻole hiki ke hoʻopau ʻia, ka pā pā, hiki ke hoʻohana ʻia ke kiʻi e like me GB8624-1997 B2 mau mea puhi ahi. No ka ʻoihana HEPA pae ʻekolu, hiki ke hoʻohana ʻia nā mea a pau o ka pūnaewele HEPA e like me nā mea papa GB8624-1997 B3.
Ma waho aʻe o nā māka, hele mai nā kānana HEPA i nā mea like ʻole. ʻO nā mea maʻamau he ʻelima ʻano: pepa kānana PP, pepa kānana PET composite, meltblown polyester nonwoven fabric a me meltblown glass fiber. ʻO nā ʻano like ʻole ʻelima o nā ʻupena kānana HEPA i ko lākou pono ponoʻī a me nā hemahema, a ʻokoʻa hoʻi nā kahua noi nui. Hoʻohana nui ʻia ka mea kānana HEPA o ka pepa kānana PP i nā mea hoʻomaʻemaʻe ea ma muli o kona kūpaʻa ʻana i ka waikawa a me ka alkali, ke kūpaʻa ʻana o ka corrosion, ka helu heheʻe kiʻekiʻe, ka hana paʻa ʻole, ka ʻawaʻawa ʻole, ka ʻala ʻole, ka hāʻawi like ʻana, ka haʻahaʻa haʻahaʻa, ka maikaʻi kiʻekiʻe a me ka mālama ʻana i ke kaiapuni.
ʻO ka hope loa, e kamaʻilio kākou e pili ana i ka mea hoʻokūkū kānana mesh HEPA ma ka mea hoʻomaʻemaʻe ea – he kānana huihuʻu HEPA i kūkulu ʻia e ka pulupulu kānana lepo HEPA me ka ʻōpū niu i hoʻā ʻia a me ka hui pūlima kalapona hoʻā. ʻO ka hoʻomaʻemaʻeʻana i ka ea e hoʻohana ana i kēiaʻano kānana Uaʻoi aku ka maikaʻi o ka mea ma mua o ka HEPA filter air purifier ma keʻano o keʻano o ka hoʻomaʻemaʻe a me ka hoʻomaʻemaʻe pono. No laila, ʻoi aku ka nui o nā mea kūʻai aku i hoʻomaka e haʻalele i ka kānana HEPA a koho i kahi hoʻomaʻemaʻe ea kānana hui.
