This filter offers reliable protection against both oil and non-oil based particles, as well as dusts and mists.
It is similar to the comfortable 8511 filter, but with a carbon layer to offer relief from nuisance levels of organic vapors such as from solvents, degreasers, and resins.
Nuisance level refers to concentrations not exceeding OSHA PEL, or applicable government occupational exposure limits - whichever is lower.
This disposable particulate respirator is a step up in quality and comfort from the thinner, non-valved 8247, and is designed to help provide prolonged protection against certain solid and liquid particles, including oil-based particles.
