Flexible and Cost-Effective Protection from Catastrophe 

A gas mask is only as good as the filters attached to it, and here at MIRA Safety, we pride ourselves on offering the very best at every budget point—like the flexible DOTPro 320.

This is the best gas mask filter for anyone on a budget or anyone who’s buying for a larger family/group. While our NBC-77 SOF filter still has it beat with a much longer shelf life, these DOTPro 320 gas mask canisters still provide outstanding performance and value that beats most competitors on the market today.

DOTPro 320 gas mask filters are designed to overcome a wide variety of chemical and biological threats—which they’re proven to do extremely well. Engineered to meet strict EU standards and accompanied by relevant filtration data (see below), DOTPro filters are at least equal in “by the numbers” quality to most filters on the market today.

Combine that with superior usability, color-coded labeling, clearly marked expiration dates and rugged construction and you get the best entry-level gas mask filter on the market today.
