DotPro 320 40mm Gas Mask Filter

Combining superior multi-gas protection with a price point that’s tough to beat, our DOTPro 320 respirator filters give you the best bang for your buck when you’re stocking up for yourself, your family, or your organization. Flexible, affordable, and built to last with a 7.5-year shelf life, DOTPro 320 multi-gas filters provide cost-effective protection for known respiratory threats.

Key Features:

• 40 mm x 1/7” NATO filter standard (EN 148-1:1999) threading
• Built to comply with a wide variety of international standards, including EN 14387:2004+А1:2008, EU Health and Safety requirements
• Practical multi-gas filter that protects the user from toxic industrial chemicals (TICs) and other threats
• 7.5-year shelf life, with expiration date clearly marked on the filter housing 
• Easy to deploy and color-coded based on the protection it offers

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 for every budget—like the flexible DOTPro 320.

This is the best gas mask filter for anyone on a budget or buying for a larger family/group. While our NBC-77 SOF filter still has it beat with a much longer shelf life and broader overall protection, these DOTPro 320 gas mask canisters provide similar levels of protection against a number of common respiratory threats.

That means DOTPro 320 gas mask filters can be just as effective as the premium alternative when facing known threats in a known environment. 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.

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.

When it comes to stocking up on gas mask filters, we advise keeping as many good filters on hand as you can comfortably afford. So, even if you’re buying a few high-end NBC-77 SOF filters, it wouldn’t hurt to have a few DOTPro filters for added protection, flexibility, and peace of mind.

NOTE: These gas mask filters are NOT designed to protect the user from chemical warfare agents (CWAs) or nuclear/radiological threats.
