Valley Guard Supply’s 3-ply barrier face covering, The Hero, meets the ASTM F3502 Standard which includes several considerations of the mask (e.g. filtration efficiency, breathability, fitting, reusability, product labeling, package guidelines, and other specifics). Below, please find information regarding our test results and design analysis.

Valley Guard Supply is committed to full transparency to its buyers and will always display any/all USA accredited test results. You don’t have to ask! If you don’t see the evidence and test results to illustrate the meeting of the new standard on another company’s website, buyer beware!

Below please find the Barrier Face Covering Report (includes breathability and filtration lab results), flammability test results, and the design analysis. The testing lab’s results are from April 2021. Together these demonstrate that VGS’ “The Hero” meets the new standard – especially documenting high performance in breathability and particle efficiency. The design analysis lists details about the non-toxic and high-quality materials used, the design elements that help with a good fit, and detailed fit measurements

*This mask is not a respirator and therefore not intended for use in medical procedures.

Please be very careful about purchasing from companies who claim to have ‘ASTM Certified Masks.’ ASTM DOES NOT certify masks. The ASTM F3502-21 standard allows manufacturers to determine compliance with its requirements only. ASTM currently has no measures in place to police companies who make false certification claims. If you see a company in violation, you can report at service@astm.org, Attn: Head of Rights and Permissions. We don’t recommend buying masks that make false ‘ASTM certification’ claims, or that fail to provide full test results to the standard on their website (you shouldn’t have to ask, and any delays when you do is a red flag).  

Any questions re: compliance to the new standard can be directed to: team@valleyguardsupply.com, Attn: ASTM F3502. A member of our executive team will respond within 24hrs.
