| P2 |
Filters at least 94% of airborne particles |
P2 masks are highly effective at filtrating smaller airborne particles in comparison to other masks such as P1 and standard surgical masks. This is due to the material used and fit of the masks to reduce the expulsion and inhalation of airborne particles. This mask also requires easier exhalation resistance and is tested for Co2 clearance.

- Approved to AS/NZ1716
- Australia & New Zealand
|
- Tight-fitting
- Minimal leakage when properly fitted
- Human fit testing required
- User seal check required
|
| N95 |
Filters at least 95% of airborne particles |
N95 masks are highly effective at filtrating smaller airborne particles in particular those in size of as little as 0.3 microns. This is due to the material used and fit of the masks to reduce the expulsion and inhalation of airborne particles.

- Approved by NIOSH as per requirements in 42 CFR
- USA & Canada

- Tight-fitting
- Minimal leakage when properly fitted
- User seal check required

>95% BFE (Bacteria Filtration Efficiency) |
Surgical masks are effective at filtering out large droplets of airborne particles. However, these are not suitable for filtering out smaller particles as the P2 or N95 masks are. Mostly used to protect against respiratory emissions. |
Three types of grades:
- Bacterial filtration (F2299)
- Fluid Resistance (ASTM F1862)
- Breathability (EN14683)
|
- Fits loosely on the face
- Edges of the mask are not tight-fitting, so leakage can occur
- No fit testing or seal check requirement
