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.

I can work comfortably I have both a gray and a pink mask that I rotate at work. Great deal with no leaks. I’ve developed an allergy to N95 material (cough/wheeze/coryza) which makes wearing a traditional N95 mask undesirable. The smaller insert in the Castlegrade mask, and the distance that the filter sits away from nares and lips, make this option doable for me. I bought one for my medical assistant too.

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.

Best PPE mask ever!! Was a blessing to have stumbled across Castlegrade company. They make the best reusable masks and cases for storage. Don’t have to worry about glasses fogging up, masks slipping off, adjustments or bruising! So comfortable to wear all day while seeing clients in the treatment room and definitely feel much safer! Their products are superior and customer service is outstanding! You guys rock! Thank you for making my family and I feel safer AND going green! ❤️

Picked wrong size because at the time… Picked wrong size because at the time did not see any videos on the site to explain how to measure for the size. Last week saw videos showing how to wear and determine size needed, so from that found that i had ordered one too large ane wasted my money getting one too small plus all the extrra filters I orded for it, so I wasted my money and so last week I orded a new one which is the smaller adult size and the side straps! Otherwise I think it is a great product. So glad to be able to get one.
