Kaarboonka firfircooni wuxuu shaandheyn karaa qaybaha dhexroorka 2-3 microns iyo xeryahooda organic kacsan (VOC) ee baabuurka ama guriga.
Shaandheynta HEPA oo dheeraad ah, waxay si waxtar leh u hayn kartaa qaybaha dhexroorka 0.05 micron ilaa 0.3 micron.
Sida laga soo xigtay sawirada Electron microscopy (SEM) ee novel Corona-virus (COVID-19) ee ay sii daysay Xarunta Shiinaha ee Xakamaynta iyo Kahortagga Cudurrada, dhexroorkiisu waa 100 nanometer oo keliya.
Fayrasku inta badan waxa lagu kala qaadaa dhibco, markaa waxa hawadu sabbayso waa dhibco badan oo ay ku jiraan fayraska iyo xudunta dhibcaha marka ay qallajiyaan.Dhexroorka nuclei-yada dhibco waa inta badan 0.74 ilaa 2.12 micron.
Sidaa darteed, nadiifiyeyaasha hawada leh filtarrada HEPA, filtarka kaarboon ee firfircoon ayaa ka shaqayn kara fayraska corona.
Sida laga arki karo shaxanka kore, waxaa jira kala duwanaansho weyn oo ku saabsan shaandhaynta shaandhaynta miirayaasha ee walxaha qayb ka ah, iyo shaandhada waxtarka sare leh ee HEPA H12/H13 ee si fiican loo yaqaan ee walxaha qaybtu waxay gaari kartaa 99%, xitaa ka fiican maaskarada N95 shaandhaynta qaybaha 0.3um.Nadiifiyeyaasha hawada ee ku qalabaysan HEPA H12/H13 iyo filtarrada kale ee waxtarka sare leh waxay shaandheyn karaan fayraska oo ay yareeyaan faafitaanka fayraska iyada oo loo marayo nadiifin wareeg ah oo joogto ah, gaar ahaan meelaha dadku ku badan yahay.Si kastaba ha ahaatee, waa in fiiro gaar ah loo yeesho beddelka joogtada ah ee shaandhada hawada sifeeyaha si loo hubiyo waxtarka shaandhaynta shaandhada.
Intaa waxaa dheer, nadiifiyaha hawadu waa wareegga gudaha, iyo hawo-qaadista daaqadu waa inaysan ka yarayn maalin kasta.Waxaa lagu talinayaa in daaqadaha la sii daayo ugu yaraan laba jeer maalintii waqtiyo joogto ah, iyadoo sifeeyaha hawada la sii wadi karo.
Noocyada cusub ee hawo-sifeeye hawo-haweed inta badan waxay ka kooban yihiin 3-in-1 filter HEPA.
shaandhaynta 1aad: shaandhaynta hore;
shaandhaynta 2aad: filter HEPA;
Sifeynta 3aad: Kaarboonka filtarka firfircoon.
Sifeeyaha hawada leh 3-in-1 filter HEPA wuxuu si wax ku ool ah uga shaqeyn karaa fayraska iyo bakteeriyada.
Si adag ugu talinaynaa inaad doorato moodelahayaga cusub ee hawada sifeeya guriga iyo baabuurka.
