Kutanga kwazvose, iyi ndiyo mipimo yemasiki, kwete chiratidzo chechifukidziro chakati, kwete muenzaniso weimwe chifukidziro, kwete basa reimwe chifukidziro, asi mupimo wechifukidzo, uri mupimo!

Sefa kuita- iyo sefa inoongororwa kuyera kudzikiswa kwehuwandu hweaerosols mumhepo inopfuura nepasefa.
Test agent-iyo aerosol inogadzirwa panguva yekusefa kuita bvunzo.
Total inward leakage (TIL)- chiyero cheiyo aerosol inopinda yakaedzwa yekufemerwa facepiece kuburikidza nesefa kupinda mukati uye kumeso kuvuza, nepo anopfeka achiita nhevedzano yemitambo mukamuri yekuyedza.
Inward leakage (IL)- chiyero cheaerosol chaiyo inopinda mukati yakaedzwa respirator facepiece, nepo mupfeki anoita kufema kwakajairika kwemaminetsi matatu mukamuri yekuyedza.Iyo bvunzo saizi yeaerosol (kuverenga yepakati dhayamita) inenge 0.5 micro metres.
Pressure inodonha- mhepo inopikisa inoiswa pasi apo inofamba nepakati, yakadai sefirita respirator.
Kubva patafura iri pamusoro, zvine musoro kufunga China KN95, AS/NZ P2, Korea 1st Kirasi, uye Japan DS FFRs se "yakaenzana" neUS NIOSH N95 neEuropean FFP2 mafemuro, ekusefa zvisina-oiri-based particles seaya anokonzerwa. kubva kumoto wesango, PM 2.5 kusvibiswa kwemhepo, kuputika kwemakomo, kana bioaerosols (semuenzaniso mavhairasi).Nekudaro, vasati vasarudza chekufemerera, vashandisi vanofanirwa kubvunza mirau yavo yekudzivirira kufema kwekufema uye zvavanoda kana kubvunza nevakuru vemunharaunda yavo yehutano kuti vawane nhungamiro yekusarudza.
