Review on Enhanced 3M 6300 Respirator: Optimal Respiratory Protection with Advanced Features by Julian Banks

Ratings are based on expectations for this product type: Filtration: 9/10 (semi-random based on odor alone) Density when worn comfortably: 7/10 Tightness when worn uncomfortably: 10/10 Mask wearing comfort correct: 5/ 10 Mask comfort worn loosely: 6 or 7/10 Sleeping comfort: 6/10 The mask is too short for me. My size is 5/10, size 280, full (I train regularly). Too much pressure on the neck, causing pain, and this in turn puts too much pressure on the bridge of the nose. test conditions. : Hawaii, less than 50 miles from and downwind of exploding Kiluea. The climate was fairly cool for the area; mid to high 70s. The most unpleasant thing: The pressure on the bridge of the nose is noticeable and quickly leads to pain. Even when the mask is worn high enough that the outer bridge of the nose touches the top of my brows (as high as I can raise them and maintain a seal), the inner crease of the mask presses heavily on that top of the bridge of the nose, which is sustained on pressure is sensitive. I'm not sure if we have the materials to improve things at the moment, but that was the main issue for me. The funniest aspect is that when you sing in this mask, the air inlet check valve (where the filters are attached) vibrates audibly. It creates a vivid resonance for whatever you say/sing, which is kind of funny. The most annoying aspect: aside from the pain, it's a rubber/silicone material that constantly touches your face creating an uncomfortable wet contact/environment. This is probably inevitable, although the hem of the skirt, which is folded a few inches and lacks drainage points, makes me a little concerned that sweat tends to pool here easily. I'll probably test that theory this afternoon.
