I find your G-9 Mask too uncomfortable to use
I am sorry to say that I find your G-9 mask too uncomfortable to use. Once in possession of the 2 masks I purchased from you, and as a retired Industrial Designer I take issue with the design of the mask. First, the silicon head strap consisting of 2 straps of the same length results in a bad fit. The measurements around any head, above and below the ears are not the same, and the stretch in the silicon banding appears to be less then with typical elasticized fabric banding. In my case the top band from the mask is quite tight around the back of my head whereas the bottom band actually drapes loosely around my neck. The result is that the top of the mask is tight at the bridge of my nose (coincidently pinching the sides of my nose shut to a small degree) but the bottom of the mask is somewhat loose against my chin. I can feel air escape with every exhale. My second, and more critical problem with your design is with the size of the breathing port - approximately a square inch. The small size of the port makes drawing a breath noticeably difficult with the 4-ply filter in place. I also notice a majority of the customer review complaints, most of them dated after I purchased the mask, involve breathing difficulty associated with the small breathing port. A typical surgical mask provides up to 12 square inches of breathing surface with the added benefit of more area to capture unwanted particulate moving at a slower velocity. Had I been on your design team I would have strongly advocated for enlarging the breathing surface. As it is, it is a real deal breaker for me! At about $40.00 per mask I can’t help feeling deceived by your website’s very thorough advertising campaign. With that high a price I regret admitting to feeling confident that I would be buying a well designed, well thought-out product. I was wrong.

Hi Peter. We disagree with your review. Nothing else to say other than that!
