N-B-1 Certifications

The chart below illustrates the filtration classification of the N-B-1

Group of Contaminants	Protect Against
A	Organic gases and vapors with a boiling point above 65°C (e.g., toluene, benzene, styrene, kerosene, petrol, isobutanol, …)
B	Inorganic gases and vapors (e.g., fluorine, chlorine, hydrogen sulfide, hydrogen cyanide, hydrogen chloride, …)
E	Acid gases and vapors (e.g., carbon dioxide, sulfuric acid, hydrochloric acid, formic acid, hydrogen fluoride, …)
K	Ammonia and organic amines (e.g., methylamine, ethylamine, dimethylamine, …)
P	Solid particles in the form of liquid and solid aerosols (e.g., dust, smoke, fibers, bacteria, viruses, and radioactive particles, …)

Classification

Meaning

R

Reusable

This means that the filter can be worn for more than one shift.

**For Reference: Number values listed after Letter ratings indicate exposure limit ratings.

A1 Organic gases and vapors with a boiling point > 65 °C; 10 x occupational exposure limit or 1000 ppm
A2 Organic gases and vapors with a boiling point > 65 °C; 10 x occupational exposure limit or 5000 ppm (e.g. like A1, but in higher concentrations)
AX Organic gases and vapors with a boiling point ≤ 65 °C
B Inorganic gases and vapors (e.g., chlorine, hydrogen sulfide, hydrogen cyanide)
E Acid gases and vapors (e.g., sulfur dioxide, hydrogen chloride)
K Ammonia and derivatives
Hg mercury vapor
P Particles, Mists, Vapors
P1: Water- and oil-based non-toxic dust and aerosols.
P2: Harmful dust, fumes, and aerosols based on water and oil.
P3: Harmful and carcinogenic dust, fumes, and aerosols based on water and oil. Against radioactive particles and airborne biological agents of risk group 3 and enzymes.
P1: 4 x Workplace Exposure Limit
P2: 10 x Workplace Exposure Limit
P3: 30 x Workplace Exposure Limit
R (reusable): Reusable, can be used for multiple shifts.
NR (non reusable): Single use, disposable filter.
D: These masks meet and passed the requirements of the optional dolomite dust test. This means less breathing resistance (easier to breathe) over a longer period of use
