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.

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.

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.

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.

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.
