Summary	Experience unparalleled protection with our advanced flagship filter, designed to shield against CBRN threats, toxic industrial chemicals, and radioactive methyliodide gas. Your trusted ally in safety.	The DOT PRO 330 Special Combined Filter is a high-performance, EN 14387-certified gas mask filter offering comprehensive protection against a wide range of CBRN threats, including unique mercury vapor filtration, with a 5-year shelf life and durability in extreme conditions.	Our P-CAN® filter is optimized for removing riot control agents and boasts a higher absorption capacity compared to the P-CAN Compact.	Our lightweight variant of the NBC-77 SOF provides similar protection against various threats, albeit at slightly lower concentrations. The primary benefit lies in its significantly reduced weight, ensuring improved mobility without compromising safety.	Safeguard yourself against toxic industrial chemicals while effortlessly converting CO into CO2 for easy exhalation. Please note, this filter is not designed for comprehensive CBRN protection.		Unlike the VK-530 filter, which is primarily designed for protection against smoke and carbon monoxide, our Special Combined Filter Cartridge offers a much broader range of protection with double the life span. It effectively filters out organic solvents, acid gasses, ammonia, mercury vapors, hydroxides, phosphoric acid and its organic derivatives, and chloroacetic acid, making it super versatile.	Our compact version of the P-CAN is tailored to efficiently filter out riot control gases while offering significant weight and size savings compared to its counterparts.	Our ParticleMax P3 filter ensures optimal coverage, effectively eliminating 99.995%+ of particulates, such as bacteria, viruses, and mold. Benefit from superior filtration capabilities while enjoying the advantages of its larger size and weight savings.

About this product

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).

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.
