1. Marka loo eego nadaafadda deegaanka, beddel miiraha cutubka filter-ka Fuurka FFU. Prenitterku guud ahaan waa 1-6 bilood, iyo miiraha HEPA guud ahaan waa 6-12 bilood oo lama nadiifin karo.
2. U adeegso miiska walxaha walxaha ah si aad u cabbirto nadaafadda aagga nadiifka ah ee ay ku daahiriso FFU mar labadii biloodba mar. Marka nadaafadda la cabiray uusan u dhigmin nadaafadda loo baahan yahay, waa inaad ogaataa sababta oo ah daadashada, ha ahaato in miisaanka HIPA uu ku guuldareysto, iwm haddii lagu beddelo shaandhada HEPA, in lagu beddelo shaandhada C HepA cusub.
3. Marka la beddelayo shaandhada HEPA iyo filterka aasaasiga ah, jooji FFU.
4. Markii la beddelayo filterka HEPA, fiiro gaar ah waa in la bixiyaa si loo hubiyo in waraaqda shaandhada uu yahay mid aan xirneyn, taabashada, waana mamnuuc, waana mamnuuc in ay taabato warqad si aad u soo saarto.
5. Kahor intaadan rakibin FFU, u dhig miiraha cusub ee HEPA meel ifaya, oo fiirso bal in filterka Hepa uu waxyeelleeyo gaadiid iyo sababo kale awgood. Haddii warqad shaandheedu leedahay godad, lama isticmaali karo.
6. Goorma ayaa la beddelaa shaandhada Helpa, sanduuqa waa in marka hore kor loo qaado, ka dib waxaa lagu guuldaraystaa in miiraha HEPA la beddelo, iyo miiraha cusub ee HIPA waa in la beddelaa. Xusuusnow in fallaadha hawada hawada ee filter-ga hepa ay tahay inuu la jaan qaado jihada hawada ee unugga FFU. Hubso in jirku shaabadaysan yahay oo daboolka dib u dhigo meesha.
