The Spartan Series Personal Safety Respirator is made from a heavier material than most masks and is designed to last.
Durable, light weight material with a replaceable PM2.5 filter and one way exhaust valves to reduce moisture make the Spartan model the mask of choice for high endurance sports.
What is a PM2.5 Filter? Particulate Matter 2.5, is the smallest and most dangerous form of air pollution. Civilian safety masks are strictly for personal use. We make no medical claims whatsoever. The simple fact is that a filtered mask is better than a plain cloth mask and significantly better than nothing at all.
