To small

This is an amazing product. I bought 3 for me and my parents for covid19 and I’m very happy with my purchase. Buy it

This thing is awesome. It's ugly and bulky, but it is quite comfortable and my glasses don't fog at all. I wear it for nearly 12 hours straight at work. Everything else I have tried hurts after a few hours or require constant adjustments or glasses cleaning. This gets me weird looks and communication can become more difficult, but I can maintain covid compliance at work without having to frequently touch my face as I did with other masks.The condensation effect is probably offputting to some, but it's a nice cooling "feature" on 100 degree days. It doesn't feel overwhelmingly hot like others which is nice.I haven't tried upgrading the filters yet, so this thing isn't truely effective against COVID but is with noxious fumes from HVAC brazing.

This mask is actually better than I expected in many ways, but unfortunately it doesn't fit me very well. Here's what I like/dislike about it.---------LIKE---------The materials and manufacturing quality are better than I expected. In particular, one-way valve flaps need to be precisely manufactured to avoid leaks. From a visual inspection, I found the quality of these valves to be comparable to those on my 3M respirator. The plastic had no blemishes, and the silicone rubber feels decent. The clasp on the neck strap is likely the weakest point of failure. The only quality control issue I found was that the extra filter was sandwiched in the wrapper when it was heat sealed. It was still usable, so not a big deal.The clasp mechanism on the neck strap, though made of weak-looking plastic, makes the mask pretty easy to don/doff. The hardest part is actually just keeping the straps from getting tangled when you're not wearing it.The one-way valves work nicely. Exhaling didn't fog up my glasses, and I didn't feel like I was breathing in my own stinky breath.The rubber smell was (for me) not an issue. I only noticed it when I was intentionally trying to smell it. It's quite subtle and not an offensive scent.---------DISLIKE---------I wasn't impressed with the seal. Surely, if you're considering this mask over a disposable one or a cloth mask, then you're looking for something that offers MORE protection than those options. No one wants a rubber thing sealed to their face unless it provides superior performance. Even though the rubber on this mask seals pretty well against skin, the weak link is the interface between the filter/plastic and the rubber part. If the filter is not sufficiently thick, perfectly cut, and perfectly fitted, it's possible for air to get past the filter instead of being forced through it. This is essentially the same problem disposable masks have. The material itself filters very effectively, but the question is how much air can sneak in through the cracks.The filter in this mask is merely sandwiched between two smooth pieces of plastic. This design would likely perform much better if it incorporated rubber gaskets. If it actually fit me and I were planning on wearing it, I'd buy a sheet of very thin rubber and cut out some custom gaskets to sandwich the filter between. The filters that come with the mask are actually thicker than I expected (comparable to a gauze bandage), so if you're making your own filters from a thin material, gaskets would help prevent leaks around the perimeter of your filters.It is too small. I'm a nearly-6-foot guy with a nose/chin combination similar to David (the statue). That is, a relatively large, high-bridge nose, combined with a prominent chin that juts out slightly. If I push this mask on my face hard enough to get a decent seal, it basically holds my mouth shut. Kind of like a dog muzzle. If I try to talk, my jaw movement drags the upper rubber portion down the bridge of my nose.In addition to being too small, it also interfered with my glasses. Specifically, it held them up slightly, which put the lower rim of my glasses higher in my visual field. In other words, the mask raised my glasses on my face, making my frames much more visible and distracting. This issue depends on the size and shape of your glasses, and might not be an issue for everyone.It looks considerably more ridiculous than I expected. The mannequin image doesn't really reflect how stupid this thing looks in real life. I've included a picture of the side profile to help you visualize how it might look on your head. As you can see, the top strap actually turns into a double strap made of plastic. It works well to secure the mask, but...you're not winning any style competitions, that's for sure.---------SUMMARY---------This mask is not a bad option for people with small-medium faces, who are willing to customize it to work with homemade filters, and who don't care much about how it looks.

I got sick of disposable masks and washable homemade masks fogging up my glasses so I opted for this due to the secure rubber seal on the nose. I anticipated masks becoming mandatory in my state, so I needed one that doesn’t annoy me. Sure, it’s harder to speak and to be understood, but I don’t feel like an idiot, it’s not hot and sweaty, and I don’t have to readjust it all the time. The straps are comfortable. It stays cool, too, due to the in/out valves. It comes with a fancy filter and a replacement, but for Covid purposes you could easily make your own from fabric or something. I anticipated getting nasty comments and odd looks, since it looks like a stormtrooper helmet, and I had comebacks ready, but no one seems to care.
