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.

Didn't send filter refills, wont refund The mask is fine, but I ordered a large number of replacement filters (25) and was shipped 5. I sent evidence of this over email multiple times over the next month and have never heard back from them. The 25 pack is 53 dollars and I was sent a 5 pack which is 12. Customer service wont email back and no refund has been issued for the 40 dollars of product I wasn't given. If you want a reusable mask, try a company who wont scam you out of 40 dollars.

The mask generally does what you expect, but . . . The mask generally does what you expect on the inhale and is probably better protection for the wearer than cloth masks, even one's with filters where the air likely follows the path of least resistance around the filter. But exhaling forces air out of the sides of the mask which is still not great for everyone around you, but that's probably no worse than other masks. However, the front filter holder cover does not snap on very securely, and if you have it on for a little while the condensate (essentially drool) builds up on your own chin. It's also more cumbersome to take off and put on than most other masks.

Great Mask and Outstanding Service I can't say enough about Castlegrade's products and customer service. The masks are easy to use and so comfortable! I work in healthcare in a field with high risk for COVID exposure. These masks are so much more comfortable than the disposable N95 masks I've been wearing for the past year and a half. Not only that, but when there was a hiccup with my order, their customer service was quick to respond and fixed the issue right away. Such a pleasant, stress-free experience! I'll definitely be recommending Castlegrade to all my co-workers and friends who want a mask with a bit more protection.

Materials look great and quality seems… Materials look great and quality seems good. Unfortunately it simply wouldn’t fit my face without leaking, nor my wife’s, nor my brother in Law’s. So, not safe enough to use for us in this pandemic, particularly with me working in the hospital. Too bad. I understand why returns aren’t possible during a pandemic, but a little bummed to spend the money on a product that we’re unable to use.
