3M N95 Disposable Half Mask Respirator, Adult, White, 10/Box (8511)

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 3M Cool Flow 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 cooler than the similar product without the valve. This makes Cool Flow 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. FFRs with an exhalation valve provide respiratory protection to the wearer and - according to the findings from the study linked below - can also reduce particle emissions to levels similar to or better than those provided by surgical masks and unregulated barrier face coverings.
