Never got it + company fat shames We never got the product and the company didn't resolve the issue. The owner insults people (referring to weight when that often doesn't even correspond with face and head size/shape) and the company makes claims that are simply not true. The owner is fat shaming instead of recognizing issues with their mask. They failed at least the breathability testing for N95 certification and made it seem as though not getting certification has to do with being American based. The surface area of the filter is simply too small for them to have had a chance of passing. I got robbed $72.24 from them and as you can see from other reviews, others have experienced the same!

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.

Seems well-made and comfortable Product arrived quickly and seems to be quite well-made and as if it will be comfortable to wear over time. I haven't given it a real try yet as I purchased them with an intent to wear in more "risky" situations and/or if someone in my immediate family gets sick, as opposed to everyday use. That said, I'm happy to have something more effective on reserve should either of those situations arise.

Excellent N95 Alternative I'm an IT technician who works at COVID testing sites along with hospitals and urgent care clinics. Suffice to say, I'm constantly exposed to suspected or positive patients and need excellent PPE. As such, I usually wear an N95 for hours on end, which ends up crushing my nose, since getting one that actually fits perfectly is nearly impossible these days. The Castle Grade mask is a game changer for me. I did a rudimentary fit test and confirmed that there were no leaks. I've been wearing this for hours on end and my nose still feels fine. Plus, my breath is less muffled than when I wear my N95, meaning that staff members can actually make out what I'm saying, not just pretend to. I plan on recommending this to my other coworkers as well.

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.
