Matanthauzo
Sefa machitidwe- fyuluta imawunikidwa kuti iyese kuchepetsa kuchuluka kwa ma aerosols apadera mumpweya omwe amadutsa mu fyuluta.
Woyesa mayeso- aerosol yomwe imapangidwa panthawi yoyeserera magwiridwe antchito.
Total inward leakage (TIL)- kuchuluka kwa aerosol inayake yomwe imalowa m'chipinda chopumira choyesedwa kudzera muzosefera zonse ndi kutayikira kwa nkhope, pomwe wovala amachita masewera olimbitsa thupi angapo m'chipinda choyesera.
Kutuluka kwamkati (IL)- kuchuluka kwa aerosol yeniyeni yomwe imalowa m'chipinda chopumira choyesedwa, pamene wovala amapuma bwino kwa mphindi 3 mu chipinda choyesera.Kuyeza kwa aerosol (kuwerengera kwapakati) ndi pafupifupi 0.5 micro mita.
Kutsika kwamphamvu- mpweya wotsutsa umayendetsedwa pamene ukuyenda kudzera mu sing'anga, monga fyuluta yopumira.
Kutengera tebulo pamwambapa, ndizomveka kulingalira China KN95, AS/NZ P2, Korea 1st Class, ndi Japan DS FFRs ngati "zofanana" ndi US NIOSH N95 ndi European FFP2 respirators, posefa tinthu tating'ono topanda mafuta monga zomwe zimatuluka. kuchokera kumoto wolusa, PM 2.5 kuipitsidwa kwa mpweya, kuphulika kwa mapiri, kapena ma bioaerosols (monga ma virus).Komabe, asanasankhe makina opumira, ogwiritsira ntchito akuyenera kuonana ndi malamulo ndi zofunikira za chitetezo cha kupuma kwapafupipafupi kapena kukaonana ndi akuluakulu a zaumoyo kuti awathandize kusankha.
