Bests & Worsts Reviews from Amazon

So, wow, a ton of mask options out there, obviously, but I found these to be the best, and my entire staff agrees. As a glasses wearer, these type seal well, yet do not fog up my glasses, which is awesome. Plus, they have a round elastic string instead of the flat elastic, so this one tucks behind my ears, much better. I love that they are each individually wrapped and sealed in their own packet! They are the true genuine KF94, from Korea, and, while it is noted that it is equivalent to US N95 (Or China's KN95) standard, the Korean standard is based on a European standard, which is somewhat more stringent in some measures. For example this mask has to pass a standard to avoid Co2 build up, which is not a standard for US N95 (which are still impossible to find anyway, or are being sold at insanely high prices). Also, this "front plate" style tests the best for protection, according to a test I reviewed, and, for me, this design is the most comfortable, since it keeps the mask off of my face and, as I said, it doesn't fog up my glasses. Honestly, the filtration differentiation is so minimal that it's inconsequential, in terms of these types of masks (N95, KN95, KF94) so, for me, it comes down to comfort, and these are the best I've found for either short needs, like running a brief errand, or working a full day at the office. I will also agree with those who have said these have no odor, which can't always be said of some other brands. I'm happy to have found these, since this particular style is not as common as the "dome" shaped ones, or the much cheaper blue surgical style (which stick to my face and fog up my glasses and I really detest). Wonderfully made, durable, comfortable protection for these uncertain times. HIGHLY RECOMMEND. I'm placing another order right now!
