masker pernapasan 3M Particulate Respirator 8511, N95 is a disposable particulate respirator that is designed to help provide reliable respiratory protection of at least 95 percent filtration efficiency against certain non-oil based particles.- The respirator is designed for use for particles such as those from grinding, sanding, sweeping, sawing, bagging, or other dusty operations. This respirator can also help reduce inhalation exposures to certain airborne biological particles (examples: mold, Bacillus anthracis, Mycobacterium tuberculosis), but cannot eliminate the risk of contracting infection, illness, or disease.- Soft inner material provides added comfort while the cup shape design makes the respirator spacious and durable. Braided headbands and an adjustable M-noseclip are designed to help enhance user comfort and increase wearability.- 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 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 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.
