Type N95 respirator aerodynamic diameter 0.075 um ± 0.02 um particle filtering efficiency of 95% or more.
Air bacterial and fungal spores of aerodynamic diameter of main changes between 0.7-10 um, also an N95 respirator protection range. Therefore type N95 mask can be used to some particulate respirators, such as grinding, cleaning and processing minerals, in the process of flour and some other materials such as dust, also suitable for fluid produced by spraying or non oily does not produce harmful volatile gas particles. Can effectively filter and purify the abnormal odor inhaled (with the exception of toxic gases), and help reduce some microbial particles can be inhaled, such as mold, bacillus anthracis, n/med tuberculosis bacili, etc.) of exposure levels.

Respirateur de type N95 diamètre aérodynamique 0,075 um ± 0,02 um efficacité de filtrage des particules de 95% ou plus.
Air spores bactériennes et fongiques de diamètre aérodynamique des changements principaux entre 0,7-10 um, également une gamme de protection respiratoire N95. Par conséquent, le masque de type N95 peut être utilisé pour certains respirateurs contre les particules, tels que le broyage, le nettoyage et le traitement des minéraux, dans le processus de farine et d'autres matériaux tels que la poussière, également adaptés aux fluides produits par pulvérisation ou non huileux ne produisant pas de gaz volatils nocifs particules. Peut filtrer et purifier efficacement l'odeur anormale inhalée (à l'exception des gaz toxiques), et aider à réduire certaines particules microbiennes peuvent être inhalées, telles que la moisissure, le bacille anthracis, le bacille tuberculeux n / med, etc.) des niveaux d'exposition.
