Set of 3 NBC military grade gas mask filters. Fits all 40mm Gas Masks. 3 Filters per order. These filters were made in 2017 by the same manufacturer who makes all the gas masks and filters for the Israeli Army. These are the top of the line Emergency preparedness nuclear, biological and chemical gas mask oxygen filters. Each filter will give you about 8-12 hours of oxygen depending on how heavily you breath. Most of the filters sold these days are expired and old. It is very important to only buy new military grade filters.
