among them:
N ( Not immune to oil ) stands for not proof against oil and can block Grime
The dye styles are sound and h2o-primarily based particles, and sodium chloride is Employed in the test.
R ( Proof against oil ) means oil resistance and may block every kind
Pollutants, use DOP ( dioctyl phthalate ) when testing , that may be
Dioctyl phthalate (synthetic expelling agent).
P ( oil Proof ) stands for oil evidence , that may be, oil resistance with stable effectiveness and resistance
The pollutants divided are the exact same since the R form, and the most load from the examination is not really limited.
As a result, N95 stands for stable and h2o-based sol (not oil resistant)
The filtration efficiency (the percentage of particles removed from the air) will not be low
Significantly less than 95% .

In the perspective on the classification of filtration effectiveness, EN 149-2 0 01 follows
The maximum inward transmission rate divides masks into three classes: FF P1 , FFP 2 and
FFP3 . According to non-oily particles (sodium chloride) and oily particles (stone
Wax) is the experimental item. The most transmittance of each and every product is demonstrated in Desk eight .
