The 3M™ Particulate Respirator 8577 helps provide respiratory protection against certain oil and non-oil based particles. This respirator features a 3M™ Cool Flow™ Valve for cooler breathing and includes a carbon layer to help remove nuisance levels* of organic vapours.The 3M Particulate Respirator 8577 is a disposable particulate respirator designed to help provide reliable respiratory protection against certain oil and non-oil based particles. A carbon layer helps reduce exposure to nuisance levels of organic vapours such as solvents, degreasers, and resins. Braided headbands and an M Nose clip adjust easily for fewer pressure points and greater comfort. This respirator incorporates 3Ms proprietary technology with advanced electrostatically charged microfibre filter media designed for ease of breathing. This respirator is compatible with a variety of protective eyewear and hearing protection. Fitted with a 3M Cool Flow Exhalation Valve, this respirator is ideally suited for work situations involving heat, humidity, or long periods of wear. The proprietary valve is designed to release hot, humid exhaled breath quickly, helping to prevent an unpleasant build up of heat inside the facepiece - a significant cause of discomfort to respirator wearers. The Cool Flow valves efficiency in keeping breathing cool and comfortable has been demonstrated through testing*: the atmosphere inside a respirator with a Cool Flow valve is on average 7.5F (-13.6C) cooler than the similar product without the valve. This makes 3M Cool Flow Exhalation Valve respirators ideal for long periods of wear, especially where conditions are hot, humid or physically demanding. *Testing conducted in a 3M laboratory. Testing protocol, data generation, and conclusions were reviewed and approved by an expert from The University of Minnesota. The testing performed by 3M is not a part of the testing and certification conducted by NIOSH. WARNING: These respirators help reduce exposures to certain airborne particulates. Before use, the wearer must read and understand the User Instructions provided as a part of the product packaging. A written respiratory protection program must be implemented meeting the requirements of your jurisdiction and/or CSA Z94.4 respiratory standard. Misuse may result in sickness or death.
