Differences Between N95, R95, P95, and P100 Respirators and Their Applications
The NIOSH standard classifies respirators based on filtration efficiency and resistance to oil into three main categories:
- N-Series (Not resistant to oil)
- R-Series (Resistant to oil, limited use)
- P-Series (Strongly resistant to oil, prolonged use)
Below is a comparison of N95, R95, P95, and P100 respirators:
Type |
Filtration Efficiency |
Oil Resistance |
Application |
Usage Duration |
N95 |
≥ 95% |
❌ Not resistant |
Dust, viruses, bacteria (non-oily particles) |
Up to 8 hours (replace if damaged) |
R95 |
≥ 95% |
✅ Short-term resistant |
Paint spraying, pesticide use, automotive repairs |
Up to 8 hours (single use) |
P95 |
≥ 95% |
✅ Long-term resistant |
Oil mist, industrial processing, refineries |
no set time limit but should be replaced |
P100** |
≥ 99.97% |
✅ Long-term resistant |
High-toxicity environments (asbestos, lead, heavy metals) |
no set time limit but should be replaced |
**If you need more high filtration efficiency, we have the P100 serie , it is be your best choose.
As for any filter, service time will be limited by considerations of hygiene and increased breathing resistance due to filter loading.
Best Applications:
- N95: Healthcare settings (virus protection, flu prevention), construction sites, dust protection.
- R95: Temporary exposure to oil-based particles, such as painting, pesticide spraying, or automotive work.
- P95: Prolonged exposure to oil-based particles, like refineries, metalworking, and food processing.
- P100: Highest level of protection, suitable for asbestos removal, lead exposure, and hazardous industrial environments.
Choosing the right respirator depends on whether oil-based particles are present and the required filtration efficiency.
