This canister features a durable and rugged design which will allows it to be effective in harsh environments. It also carries a filter classification of R, meaning that is is reusable for multiple shifts/exposures.
Some of its core features include:
- Durable Canister for Harsh Environments
- Filtration classification of A2P3 R (more details below)
- Compatible with all 40mm Gas Mask Ports
- Reusable for multiple shifts/exposures
- Caps to seal filter when not in use (increases lifespan)
- Low Breathing Resistance
FAQ:
Q- Can the N-B-1 be used with any Parcil Safety 40mm respirators?

The chart below illustrates 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, …) |
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 dusts and aerosols.
- P2: Harmful dusts, fumes and aerosols based on water and oil.
- P3: Harmful and carcinogenic dusts, fumes and aerosols based on water and oil. Against radioactive particles, as well as 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 more than one shift.
- 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
