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 3M’s 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 valve’s 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 7.5°F (-13.6°C) 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.
