Fyuluta ya HEPA ndiye fyuluta yayikulu yomwe imagwiritsidwa ntchito pazoyeretsa zambiri. Amagwiritsidwa ntchito kwambiri kusefa tinthu tating'ono tating'ono tating'onoting'ono ndi zolimba zosiyanasiyana zoyimitsidwa ndi mainchesi opitilira 0.3μm. Kusiyana kwamitengo ya zosefera za HEPA pamsika ndikwambiri. Kuphatikiza pamitengo yamitengo yokha, pali ubale wina ndi mulingo wa zosefera za HEPA.
Zosefera za HEPA ndi zina zotere zagawidwa mu G1-G4, F5-F9, H10-H14 ndi U15-U17 malinga ndi sikelo yapano yaku Europe. Mtundu wodziwika bwino woyeretsa mpweya ndi mtundu wa H, womwe ndi fyuluta yabwino kapena yocheperako. H13 imadziwika kuti ndiye fyuluta yabwino kwambiri ya H13-14. Fyuluta ya HEPA ya kalasi ya H13 imatha kukwaniritsa bwino kwambiri 99.95%. Kukwanira kwathunthu kwa fyuluta ya H14 grade HEPA imatha kufika 99.995%.
Zachidziwikire, mulingo wapamwamba kwambiri woyeretsedwa wa fyuluta ya HEPA mu muyezo waku Europe ndi U grade, ndipo fyuluta yabwino kwambiri ya U-17 giredi HEPA ili ndi kuyeretsa kwathunthu kwa 99.999997%. Komabe, chifukwa fyuluta ya U-grade HEPA ndiyokwera mtengo kupanga, ndiyofunika kwambiri pakupanga. Kotero palibe ntchito zambiri pamsika.
Kuphatikiza pa kalasi yoyeretsedwa, fyuluta ya HEPA ili ndi mlingo wamoto. Msika umagawidwa m'magulu atatu malinga ndi kuchuluka kwa kukana moto: ma mesh oyambirira a HEPA, zipangizo zonse za mesh ya HEPA sizingapse, ndipo zinthu zosayaka ziyenera kugwirizana ndi GB8624- 1997 Kalasi A; sekondale HEPA maukonde, HEPA mauna fyuluta zakuthupi ayenera kukhala zosemphana ndi GB8624-1997 Kalasi A zipangizo zosayaka, mbale kugawa, chimango angagwiritsidwe ntchito malinga ndi GB8624-1997 B2 kalasi zipangizo kuyaka. Pamaneti atatu a HEPA, zida zonse za netiweki ya HEPA zitha kugwiritsidwa ntchito molingana ndi zida za GB8624-1997 B3.
Kuphatikiza pa magiredi, zosefera za HEPA zimabwera muzinthu zosiyanasiyana. Zida zodziwika bwino ndi mitundu isanu: PP fyuluta pepala, gulu PET fyuluta pepala, meltblown polyester nonwoven nsalu ndi meltblown galasi CHIKWANGWANI. Mitundu isanu yosiyanasiyana yamanetiweki a HEPA ili ndi zabwino ndi zoyipa zawo, ndipo magawo ogwiritsira ntchito ndi osiyana. Zosefera za HEPA za pepala la fyuluta ya PP zimagwiritsidwa ntchito kwambiri poyeretsa mpweya chifukwa cha kukana kwa asidi ndi alkali, kukana kwa dzimbiri, malo osungunuka kwambiri, ntchito yokhazikika, yopanda poizoni, yopanda fungo, kugawa yunifolomu, kutsika pang'ono, kugwiritsa ntchito bwino kwambiri komanso kuteteza chilengedwe.
Pomaliza, tiyeni tikambirane za HEPA mesh fyuluta wopikisana naye pa air purifier - fyuluta yophatikizika ya HEPA yopangidwa ndi thonje losefera fumbi la HEPA yokhala ndi chipolopolo cha kokonati chokhala ndi kaboni komanso chophatikizika cha kaboni fiber. Kuyeretsa mpweya pogwiritsa ntchito fyuluta yamtunduwu Chipangizocho ndi chabwino kuposa HEPA fyuluta mpweya woyeretsa potengera mtundu wa kuyeretsa ndi kuyeretsa bwino. Chifukwa chake, ogula ochulukirachulukira ayamba kusiya fyuluta ya HEPA ndipo m'malo mwake amasankha choyeretsa mpweya chophatikizika.
