VERY POOR SERVICE. VERY POOR SERVICE. I ordered two masks and additional refills for a trip we were taking (on a plane). Ordered well in advance of their delivery schedule (listed on their website) and the masks didn't arrive until we were already gone!! I wanted a refund, they just continued to send some BS email about they have no control over their shipping (why put shipping times/days on their site then???). When I decided to try one of the masks on it doesn't fit properly and they still won't refund. DO NOT BUY FROM THIS COMPANY - THERE ARE PLENTY OF OTHER MORE REPUTABLE PROVIDERS FOR MASKS....

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.

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.

Don’t Waste Your Money Received four masks today for two adults. The masks are useless, no seal, so air simply passes around the mask, not through the filter. Their return policy does not allow for returns based on fit or effectiveness, in effect allowing them to sell to new customers without having to pay back money when the masks are received.

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.
