Review on MSA Comfo Classic Half Rubber by Justin Santiago

I bought this mask to replace a worn out AO Smith steam mask that I have used for years. The design is almost identical as I believe MSA bought out AO Smith many years ago. The mask fits very well with no air leaks or a tendency to bind features like 'other' brands. Vapor canisters are a bit pricey but do the job they were designed to do. Don't waste your money on cheap masks if you're worried about protection from toxic fumes.
