Moldex® 2840R95 Series particulate respirator with HandyStrap® for nuisance levels of Ozone and Organic Vapor Odors are NIOSH certified to have a filter efficiency of 95% or greater against oil and non-oil based particulates. Added carbon layer helps relieve workers of nuisance levels (less than OSHA Permissible Exposure Limit) of ozone and organic vapor odors. Exclusive HandyStrap® allows mask to conveniently hang down around the user's neck so it’s always ready for use. And during wear the adjustable cloth strap is more comfortable and cooler. Exclusive Ventex® valve lets the hot air out faster so breathing resistance is reduced and workers stay cooler. The Dura-Mesh® shell protects the filter media so it stays cleaner looking longer. Plus it resists collapsing, even in heat and humidity so the respirator holds its shape longer. The result is fewer respirators used and lower costs.
