I have a wider face and found a lot of N95/KN95 masks to really hurt my ears because of how much they tugged. I wanted something a bit more heavy duty than the regular surgical style masks, and was looking into KN94 because they seemed to be a bit more forgiving due to the boat shape; however a few that I've purchased at in-person stores gave me issues because of how much they would move when I spoke due to the nose and chin panels not being long enough.These are great! They're wide enough on the sides that I don't have any issues with tugging or pain on my eaers, and the panels for your nose and chin are also long enough that they don't move around too easily if you're talking a lot. If you have a larger/wide face and have had trouble finding masks that fit, I definitely recommend giving these a try! I'm not a scientist so I can't speak to their efficacy but they sure are the most comfortable masks I've tried so far.I have a big face so when I saw all the reviews saying the product was too “loose”, I wanted to test it out. It fits my face but it’s still a bit loose but I don’t mind when I breathe it doesn’t go out the top or the bottom. But the bottom is sometimes a bit itchy, also this mask is a bit pricey it’s almost a dollar per mask… I smelled a bit of a chemical smell but it went away quickly and the mask kinda bothered me cause it was in my peripheral vision but I got used to it after a bit.Have bought these multiple times. I chose these comfort@94% vs Discomfort@95% (I.e. n95). I do travels for work. In the most recent trip, I had an indirect contact (lady who sat in the front of me during 11-hr flight tested positive at post arrival PCR ) and a direct contact at the worksite (guy I had 1:1 meeting with tested positive next day). Thanks to the mask mandate in this country, I was fine fortunately. I appreciate the great fit and the good protection these masks provide. Will definitely buy again.This is the most comfortable mask I’ve found — fits securely around the edges.These are real KF94 masks from South Korea. KF94 masks are essentially the same as US N95 masks, with one very minor and one significant difference. KN95 masks filter out 94% of airborne particles, while N95 masks filter out 95%. The big difference is how KN94 and N95 masks fit. For me, N95 masks are somewhat awkwardly shaped and do not form fit all the way around, but the KN94 have a much more natural fit because of the three (versus two) section design. That also makes the KN94 way more comfortable.The reviews that complain about the four layers of filter material in the center section (that covers your nostrils and mouth) and only three layers at the top (nose bridge) and bottom (chin) misunderstand why the masks are designed this way. The extra fourth layer of filter is only necessary in the center section because that is the only part where air passes into/out of your mouth and nostrils. The sections at the top across the bridge of your nose and at the bottom on the chin pass far less air in/out than the center piece does. The important thing to know is that the design is tested and certified to block 94% of airborne particles.These are really comfortable because of the three panel design, and the inner most fabric layer is very soft, almost like a piece of cotton fabric. This makes it easy and comfortable to breathe, even when playing fast paced sports.The fact that these are individually wrapped also means that they are far more sanitary than the masks that you buy stacked together in a box.Highly recommended. I definitely prefer these to N95 masks. I have bought these multiple times. I wish they were available in larger quantities.It works well. No noticeable strange scents. It does fit kinda loose no matter how hard I pinch the wire. It doesn’t fog my glasses and my ears don’t hurt from the pressure of the bands.These are my favorite masks. I needed something more comfortable than the regular disposable masks for an 18-hour flight. It's designed so that it doesn't smoosh up against your nose and mouth like regular masks. More expensive, but considering how long I was required to wear a mask, it was worth it.I wanted to take a step up from cloth masks and decided to go with these. I have two jobs which require me to do a lot of talking while wearing a mask (as a therapist and as a yoga instructor), and I thought that the KN94 mask would leave more room for my mouth.First, a few things about these masks. They are individually packaged and come flat. The masks seem well-made, with sturdy, stretchy straps. They are black on the outside and white on the inside. They fit VERY well, better than any other masks I have tried; the mask smoothly lies against my cheeks and covers my chin. The masks have a nose wire, and once I get it adjusted properly, my glasses don't fog up.Although these masks feel thin, I do think they offer very good protection - I get that sense from the way moisture condenses inside of the mask. Unfortunately, this is also a downside to wearing them. They work quick well if I am just talking/having a conversation (doing therapy), but if I am moving around a lot (teaching yoga), I tend to get overheated and almost start to feel lightheaded wearing these masks. So, while I believe these masks are a quality product, what you plan to use them for might impact how well you do or don't like them.Fue mi segunda opción porque no había Dr Puro, sin embargo cómo está en coreano todo; no me di cuenta que era talla chica y yo la necesito grande o extra grande.Easy to breathe.
