1. Kev siv pov tseg, ib leeg-siv, breathable, lub teeb thiab ib puag ncig-phooj ywg;
2. Lub siab elasticity lub pob ntseg sib pab ua kom haum rau cov neeg siv sib txawv thiab ob tus taw tes txuas ua ke pab muab lub cim ruaj khov;
3. Kho tau qhov ntswg zaws kom muaj kev nplij siab ntxiv;
4. Tsawg kawg 95% pom kev ua haujlwm tiv thaiv qee yam uas tsis muaj roj hauv lub ntsej muag.Qhov qhov ua kom zoo ntawm kn95 qib qhov ncauj qhov ntswg rau cov nplais nrog cov kis ya nrig diameter0.3µm siab dua 95%. Lub aerodynamic txoj kab uas hla ntawm cov pa kab mob thiab cov pa nphoo spores feem ntau nws txawv ntawm 0.7-10µm, uas tseem nyob hauv nws cov chaw tiv thaiv.
Yog li, hom npog ntsej muag no tuaj yeem siv rau kev tiv thaiv kev ua pa ntawm qee yam teeb meem, xws li sib tsoo, ntxuav thiab ua hmoov av los ntawm cov zaub mov, hmoov thiab lwm yam ntaub ntawv. Cov teeb meem ntsig txog cov teeb meem tsis haum roj.
Muaj peev xwm ua tau zoo lim thiab ntxuav qhov ua pa tsw phem (tshwj tsis yog muaj kuab lom), pab txo qis cov kab mob sib kis tau (xws li pwm, anthrax, tuberculosis, thiab lwm yam), tab sis nws tsis tuaj yeem tshem tawm kev sib cuag, kis mob lossis tuag txaus ntshai ntawm Cov.
