P3-Certified Protection Against Airborne Pathogens – Compatible with 40mm NATO Gas Masks
Engineered for Extreme Biological Hazard Protection
The ParticleMax® P3 Filters deliver military-grade particulate filtration for viral, bacterial, and bioaerosol threats. Certified to EN 143:2000 P3 standards, these ULPA (Ultra-Low Penetration Air) filters capture 99.9999% of airborne particles down to 0.2 microns—including pandemic viruses (COVID-19, H1N1), bacteria, and mold spores. When paired with a full-face CBRN mask, they provide superior protection versus half-mask respirators or surgical masks by sealing vulnerable eye/nasal tissues.
Bundle contents: 6 sealed filters (six-pack).

Critical Applications & Limitations
Contains no activated carbon; does not remove gases or vapors. Use appropriate CBRN gas filters for gaseous threats.
Protects Against
- Airborne viruses (e.g., Coronaviruses, Influenza, Ebola)
- Bacteria (e.g., Tuberculosis, Anthrax)
- Bioaerosols, mold spores, allergens
- Particulate-phase radioactive fallout (dust/ash; not radioactive gases)
Does Not Protect Against
- Chemical warfare agents (CWA) and toxic industrial gases (TICs)
- Radioactive iodine gases (e.g., I-131)
- Oxygen-deficient atmospheres
Use only with certified respirators achieving a verified facial seal.
Engineered for Reliability
- Military-Grade ULPA Media: Technology used in semiconductor cleanrooms (MERV 20 equivalent).
- Hydrophobic Design: Withstands decontamination showers and humid environments (tested up to 98% RH).
- Rigorously Validated: Proven efficacy in aerosol concentrations up to 20 ± 5 mg/m³ with <0.05% penetration (tested at up to 95 L/min airflow).
Included & Support
- Contents: 6 × sealed ParticleMax® P3 filters
- Disposal: Incinerable for safe disposal after use
Storage
- Store in original packaging in a cool, dry place at −50 °C to +50 °C (−58 °F to 122 °F).
- Humidity: Up to 98% RH when packaged; protect from precipitation and groundwater.
- Avoid exposure to hazardous substances; storage outside specified conditions may reduce shelf life.
Expertly Answered Questions
Q: Can these filters protect against nuclear fallout?
A: They capture particulate radioactive fallout (e.g., dust/ash) but do not block radioactive gases like Iodine-131 due to lacking activated carbon. Use CBRN gas filters for gaseous threats.
Q: Are these compatible with my 40mm NATO mask?
A: Yes. They meet STANAG 4155, EN 148-1 (40 mm × 1/7"), and GOST threading standards for 40 mm NATO-compatible masks (e.g., MIRA Safety, Avon, FM53/FM54).
Q: Why choose P3 over N95/KN95?
A: P3 filters capture >99.9999% of 0.2-micron particles vs. N95’s 95% at 0.3 microns. In a full-face mask, they also protect the eyes/face seal area—critical for high-risk pathogens.
Compliance Notes
- Tested per EN 143:2000, EN 12941, EN 12942
- Not a substitute for CBRN gas filters; always match filters to the threat type
- Shelf life printed on each filter; replace if damaged or expired
- Effectiveness depends on achieving an airtight seal with a certified respirator
