Gas Mask Filters

A gas mask is only as good as the filter it is attached to. It is absolutely crucial that one chooses the correct filter for the threat at hand. As such, we’ve provided an in-depth comparison chart of each filter we currently offer, which includes relevant information such as certifications, applications, CBRN breakthrough testing, specific CBRN agents tested against, shelf life, and other key data points to help you make the right decision.

FILTER MODEL / PARAMETER	NBC-77-SOF	P-CAN®	VK-530	VK-700	NBC-17-SOF COMPACT	DotPro 330	PARTICLEMAX P3	P-CAN COMPACT
Summary	Protects against CBRN threats, riot control agents, toxic industrial chemicals, and radioactive methyl iodide.	Removes riot control agents with higher absorption than the P-CAN Compact.	Protects against toxic chemicals and converts CO to CO2, but not for full CBRN protection.	Special Combined Filter Cartridge offers broader protection and double the lifespan compared to the VK-530, filtering multiple harmful substances.	The lightweight NBC-77 SOF offers similar protection at lower concentrations, enhancing mobility without compromising safety.	Offers comprehensive Toxic Industrial Chemicals protection , mercury vapor filtration, and durability with a 5-year shelf life.	Removes 99.995%+ of particulates, offering superior filtration with larger size and weight savings.	The compact P-CAN efficiently filters riot control gases with significant weight and size savings.
