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.

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.

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!

Design problems and poor fit around nose I've tried lots of disposable masks but this is one of only two elastomerics I've tried and for me it's unwearable. I have a small female face and bought the small size. Issues are: 1) the attachment point where the headstrap meets the mask body (only one) is positioned so that the "rim" of the mask is pushed hard against your face and this pushes flesh against teeth inside the mouth. The standard length strap supplied with the small size mask is too short; even on the longest setting, meaning strong pressure against the face. Very uncomfortable. 2) I could not get a good seal around the nose, reliably, no matter what I tried. I have a small and narrow nose and the mask gaped no matter how I positioned or tensioned it. 3) The strap is single where it attaches to the mask, then divides and is supposed to go one strap above and one below the ear. But the two sections of the strap are not independently adjustable and the lower strap sags and the upper strap slides down over the ears when you have long hair, and ends up too low on the head. If the higher strap is positioned above the occiput as is usual for N95 masks, the angle is wrong and because of the single attachment point the mask gapes even more around the nose, while the lower part of the divided strap, again, is loose. 4) The surface area of the filter through which air can pass is very small, meaning that there is high breathing resistence. 5) It is almost impossible for people to hear me speaking in this mask. 6) I have not worn it for long enough to be sure, but I suspect the mask would accumulate condensation if used for long periods; it feels clammy even after a few minutes. Including postage I paid $80AUD for this, and I regret the purchase. I did not bother contacting castlegrade to express dissatisfaction with their product as they were emphatic with their "no returns" policy. Unusually these days, there was no followup email to seek feedback.

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.
