Mask standard

The US standard divides masks into three categories:

N series: only used to protect non-oily particles, no time limit

R series: protection against oily and non-oily particles in a limited time, limited time for oily particles (8 hours)

P series: long-term use for simultaneous protection of oily and non-oily particles, time-consuming for oily particulates: 40 hours of cumulative use

According to the filtering effect, the filter material is divided into three grades:

Class 95: Minimum filtration efficiency ≥95%

Grade 99: Minimum filtration efficiency ≥99

100 grade: minimum filtration efficiency ≥99.97

European Standard (EN Standard)

European standards stipulate that all masks must have the ability to protect two types of particles:

FFP1; filtration efficiency ≥80%

FFP2: Filtration efficiency ≥94%

FFP3: Filtration efficiency ≥97%
