We do not sell, ship, or stock anything, and we have not physically tested this half mask respirator. What we do is read the published MSA specification against the governing standard, flag what the listing does and does not state, and place the product in context next to the alternatives we cover. Where a number matters for compliance - a rating, a class, a temperature, a voltage - we take it from the manufacturer listing and expect you to confirm it on the live listing before you buy.
