I'm long winded, so I'll give you the punchline first: For the price, these masks: 1] are much better than I expected 2] have some amount of variation in strap length that doesn't matter for my shape/size of face but could matter for small faces 3] have all the "right" markings, although to me that's no guarantee of a mask not being counterfeit 4] are lightweight and comfortable for my face 5] don't seal wonderfully around the bridge of my nose when exhaling; fogs up glasses/sunglasses. Seems to seal fine when inhaling. In other words, low risk of outside air sneaking in unfiltered, highly likely unfiltered exhaled air from you would get out. Don't wear these around your high risk grandma if you are trying to protect her from you. 6] definitely have 5 distinct layers (see picture). Long-winded verson: As with any commercial product nowadays, it's hard to know what to expect after reading reviews. The most vocal and emotional reviewers are generally those that get a crappy product and are understandably upset. When I'm shopping for the best value version of any cheap, mass produced item, I fully expect there to be some percentage of products that made it out the door with defects. That said, the box of Funight masks that I just received are much better than I expected. I haven't opened every single mask up, so there may be some in this box that have some of the issues mentioned in other reviews (ear straps that easily detach for instance), but so far so good. At this price, I'll be happy if 3/4 of these don't have defects. I don't claim to be a filtration expert, but I know enough about filtration media to know that the type of material matters much more than the amount. In this case, for anyone basing their choice on these masks having 5 layers as advertised, they do; I attached a picture of a section cut out showing all 5 layers seperated. I wouldn't have been too surprised if they didn't at this price, but hey, I'll take it! Also, all of the "correct" markings ("KN95" and "GB 2626-2019") are thermally compressed into the mask, not that I personally think that means anything. I can't imagine there is some reason that counterfeiters can't put the right markings on their masks; relying on that as an indicator of masks being legitimate makes about as much sense as looking for markings that say "counterfeit" on counterfeit masks. These Funight masks are really comfortable for me, and do a great job of sealing around my face, except up over my nose, where they do allow some air to flow out and fog up any glasses/sunglasses I might be wearing. They're no worse than the accordian/surgeon style masks I've worn previously though. They are comfortable over my nose, but all masks I've tried that don't have an extra strip of rubber/foam to help seal don't do a very good job for me, even some very uncomfortably tight N95 masks don't get this part right. For reference, I'd guess I have a medium size face/head for a man. I have recently tried some 3M 9205+ masks that seal amazingly well over my nose while still being comfortable in that area. There are other drawbacks though; mainly price (about 4x the price of these Funights) but also they aren't nearly as comfortable to me as these KN95 style masks with earloops instead of full head straps. I use the 3M N95 masks if I feel the situation is more critical; i.e. I'm in a high risk area (crowded with lots of random people) or if I'm getting on an airplane. I bought these Funight masks to use in more "everyday" situations that I don't expect to be particularly high risk, but I'd like to be wearing something more effective than a cloth mask or a single or double layer accordion style mask. The only quality control issue I've seen thus far is, as lots of other reviews have mentioned, the ear loop lengths vary noticeably from one mask to another. Thus far all of the lengths have been fine for me; none have been too tight; some have been a little loose but putting one twist in the ear loop has been enough to get it just right. The straps seem to have a lot of stretch, so the batch I have would probably be fine for someone with a larger head than me, but might be too loose for someone with a really small face/head.

I’m pleased to report these work well for me. They fit well, are sturdy and comfortable, and they feel safe because there are no gaps. They seem to last awhile, too, which I like because I don’t want to add a ton of non-biodegradable masks to landfill. I prefer to keep several masks in rotation, airing them when they are not in use, so that I can re-use them. (It’s 3years into the pandemic, I live in NYC and ride the subway, yet haven’t gotten Covid yet.) I would buy these again. I searched like crazy for masks on a par with a very expensive type my mother-in-law kindly sent us at the beginning of the pandemic. This is the first mask I’ve found that matches those for sturdiness, durability, fit, and safety. These measure 6-3/8 inches from top to bottom (measuring from point to point of the folded mask) and 4-1/4 inches from the widest point side to side on a folded mask. Unfolded, that would be 8-1/2 inches wide. The design is such that the masks come deeply under my chin, which I like because it provides great coverage. I have what I’d describe as a medium sized face. I do find these masks comfortable—however, I do not put the ear loops around my ears. Rather, I use a lace and tie the mask on in back, using the ear loops. I find wearing masks this way to be far more comfortable, and I can control how tight I want the mask to be. My only minor complaint is that these masks smell a bit mildewed straight out of the box. To address this, I leave the mask in a sunny window 24 hours before wearing it. A very faint smell lingers. For that reason, if half stars were available, I’d give these 4.5 stars. But on consideration, I decided not to knock off a star, because I’m so pleased with these for all the reasons that are most important to me.

This is a great product at a great price. Great for everyday use. I will be buying it again.

The masks is made of non-woven fabric inside and outside ,but the material is not soft enough for kids use.

The masks are comfortable and easy to use. The straps don't cut behind your ears and are pretty soft. It covers my whole mouth, nose, and chin so I feel much more protected. I can breathe easier as well, it doesn't feel too stuffy. Wish they were more adjustable though, but you can buy little adjusters so its no big thing.

Love these masks! They fits snugly over nose and mouth without leaking and are comfortable to wear. They don’t hurt my ears!

Nice disposable mask. Fits nicely and can breathe easily. Comfortable fitting elastic behind the ears.

I will only purchase these kn95 masks. The fit is perfect,Especially the ear loops. Working in healthcare I feel very safe wearing these masks.

Get exactly what you expect. Correct number, vacuum sealed in 10 packs. Work well to filter out powdery environment. Elastic for ears are not irritating or weak. Will purchase again.

Fast delivery. I tried it right away, and was hoping that it would work like the previous model that I had bought. But unfortunately, it is not suitable for my face at least because it doesn't stick well on the cheeks and under the chin and it allows air to pass through these parts easily which is a big problem and against what the mask is supposed to do. It surprised me considering a lot of good reviews I had read. The second problem is that it has been packed ten to ten and not separately. It was disappointing. I have to return it and buy the previous one, which is much more expensive, but does the job well.

The material feels cheep, not comfortable at all with the nose support and the ear bands. The pictures shown comparison of Funight this brand on the left and the other manufacturer KN95 given by my friend on the right. Big differences already on the appearance with material, size, thickness, and comfortablness. Big dissapointmen, don't get fooled by the reviews!
