Lub ntsiab zoo:
1. Nrog FDA pom zoo, ISO, CE tau ntawv pov thawj
2. Nrog EN14683: 2019 Hom IIR daim ntawv ntsuam xyuas
3. BFE (Bacteria Filtration Efficiency) ntawm 99%
4. Yuav muaj xim sib txawv thiab luam ntawv tsim, zoo yuav zoo ib yam.
Khoom siv
Txheej txheej | xiav (los yog lwm yam xim) cov ntaub uas tsis yog woven, zoo lim cov pa phem hauv huab cua. |
|
Nruab nrab txheej | dawb yaj tshuab ziab khaub ncaws, txheej tseem ceeb tshaj plaws los xyuas kom meej qhov zoo. Raws li cov kev xav tau zoo sib txawv, peb tau xaiv cov ntaub nplaum sib txawv rau lub ntsej muag lub ntsej muag. | |
Sab hauv txheej | dawb tsis woven ntaub, mos thiab mos rau ntawm daim tawv nqaij, breathable | |
Pob ntseg | 1. Round lossis tiaj earloop rau koj xaiv; 2. Flat earloop yog yooj yim rau hnav. |
|
Nose choj | muaj 3 yam khoom rau kev xaiv. 1. Feem ntau yog ib lub xov hlau qhwv nrog yas; 2. Ob lub xov hlau qhwv nrog yas, nws yog qhov zoo dua qub; 3. dav yas qhov ntswg choj, nws yog tshwj xeeb rau cov me nyuam uas tsis muaj cov qauv ntawm lawv lub qhov ntswg tau tsim. |  |
Xim muaj
Dawb, xiav, ntsuab, liab, dub… lossis lwm yam xim raws li qhov xav tau
