The filter has little holes in it, which makes the mask almost useless and also dangerous. The mask doesn’t pass the candle test. I can’t blow out the candle but I sure can move the flame around wearing this mask. My triple layer cotton masks are better.

Mask does not fit even though I got the largest size. No one has returned my calls or emails.

Great concept, A- for effort. However, my first trip into Costco the mask was literally sliding off of my face after 30-45 minutes due to moisture buildup inside the mask which accumulated in a “pool” at the bottom of the mask. I ordered the M/L so I’m not sure what else could’ve been done.

The strap, extended to the longest, was still too short. This made the mask un-wearable. I bought the largest size, and my head is not unusually large. Another half-inch of rubber on the strap would have been a good investment, and made the mask usable. The mask fit pretty well on my face, but is not usable without around the head or behind the ear straps. Disappointing because the concept is good.

The M/L mask did not fit either of us so it was a total waste of money- filters and all!

I love this mask and the Castlegrade customer service! This mask is great and definitely keeps you more protected than any standard surgical mask. Although this mask isn't NOISH certified, it is approved by the Australian equivalent of the FDA, and is FDA registered like some surgical masks and the KN95 mask. However, unlike those masks, this mask hold a solid suction seal around your face making it much better than most other masks, probably including some N95 masks. But be aware that this masks is harder to breathe in than most masks. With this in mind, while it's not great for exorcizing or speaking, it is great for times when exposed to a lot of people or pathogens like in a mall, store, or public bathroom. The style of the masks looks a little post apocalyptic which is why in retrospect I should have gotten the grey one, but I also looks kind of cool looking like Bane. Initially when I got this mask I liked it, but there was a slight defect in it. Only one side clicked closed on the front of the mask. However, after emailing Castlegrade about this, they immediately sent me a new mask with 5 filters.

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.

Mask is too small. My nose bumps into the end and the mask does not seal around it periphery. I had hoped it would eliminate my fogging glasses but that is still a problem too. Expensive mask that I can't use.
