Design problems and poor fit around nose I've tried lots of disposable masks but this is one of only two elastomerics I've tried and for me it's unwearable. I have a small female face and bought the small size. Issues are: 1) the attachment point where the headstrap meets the mask body (only one) is positioned so that the "rim" of the mask is pushed hard against your face and this pushes flesh against teeth inside the mouth. The standard length strap supplied with the small size mask is too short; even on the longest setting, meaning strong pressure against the face. Very uncomfortable. 2) I could not get a good seal around the nose, reliably, no matter what I tried. I have a small and narrow nose and the mask gaped no matter how I positioned or tensioned it. 3) The strap is single where it attaches to the mask, then divides and is supposed to go one strap above and one below the ear. But the two sections of the strap are not independently adjustable and the lower strap sags and the upper strap slides down over the ears when you have long hair, and ends up too low on the head. If the higher strap is positioned above the occiput as is usual for N95 masks, the angle is wrong and because of the single attachment point the mask gapes even more around the nose, while the lower part of the divided strap, again, is loose. 4) The surface area of the filter through which air can pass is very small, meaning that there is high breathing resistence. 5) It is almost impossible for people to hear me speaking in this mask. 6) I have not worn it for long enough to be sure, but I suspect the mask would accumulate condensation if used for long periods; it feels clammy even after a few minutes. Including postage I paid $80AUD for this, and I regret the purchase. I did not bother contacting castlegrade to express dissatisfaction with their product as they were emphatic with their "no returns" policy. Unusually these days, there was no followup email to seek feedback.

Love it. This idea looks soo coolon the pretty models in the pics. Im totally satisfied with the item and with covid cases surging with out shutdowns this will be handy for maximum protection. It’s comfortable and fits well. No strange smells and it comes in a sterile package. It’s aesthetically pleasing, between my Mohawk and spiked clothing it completes the Apocalyptic look for me. Onward mad max.

Quick and personal responses to my… Quick and personal responses to my email questions and concerns. Quick shipping. Mask works very well. Makes me feel safer than any other mask against the delta variation of the coronavirus. I love that it is reusable to save the environment from single use masks. I highly recommend this mask. My son and his wife and two children also recommend them especially since one of the boys has asthma which is viral induced and cannot risk getting Covid. I love that the mask is now FDA approved as well.

This seems to be a very durable… This seems to be a very durable product, yet we were surprised by the small size. We had to adjust the straps; fortunately, despite no instructions about this, I was able to make the straps looser with a letter opener. The directions were in very small type--even with reading glasses, they were challenging to read. Despite these challenges, they seem very durable and should last a long time.

No more fogging glasses with this solid mask A solid mask that for a glass sweater is a great no fog, solid seal solution I was looking for. I have tried so many masks, and even backed some crowd funded campaigns and the low quality, horrible deals and fit were making me tired and feeling defeated. But a friend bought me a camo colored version and I am so happy to have found a solution. This mask feels so comfortable, it is not good for heavy athletic use but wearing it for extended time feels secure. I like how easy it is to clean and when someone asks me what works for my fogging glasses I turn them to CastleGrade as there really is nothing comparable out there.
