Review on Stay Safe In Hot And Humid Environments With 3M Particulate Respirator 8576 - Pack Of 10 With P95 Protection And Carbon Filter by Relap Villa

The Bad: This respirator does not fit my large head (even after pulling the elastic through the staple to the very end), the four staple points push painfully into your skin, and it does not block all odors.The Good: The material feels nice, the seal seems complete, and the angle the straps pull at keep a strong seal. It is quite streamlined, and the most comfortable mask I've tried sleeping in between 1 washable mask, 1 silicone mask, and this mask. For the most part, this mask does block odor, however, when there's dog poo nearby, I promptly smell it through the mask. Other than that, it seems to work pretty effectively. Because the elastic bands are too short for the diameter of my head, the bands cut painfully into the back of my neck, and the mask is pulled forceably onto the crown of my nose, and the staples dig into my face even more than if the mask fit properly. After about six hours of wear, the mask starts to develop fray strands of fiber which tickle irritatingly at your face. Thinking the material was cotton, I singed it with a lighter, at which point I discovered the material is nylon or the like. Singing creates a rough surface, and is not a quick and easy way to resolve this discomfort.All in all, I think this mask is really good for a couple hours of wear, particularly if you have a smaller head. For prolonged use, you'll be going through the 10 count, and I'm not a fan of regular use of disposables.
