I've tried many types of masks during Covid-19. I find the KF95 Korean style to be the most comfortable for my face. It does not collapse onto your face while breathing in and seems to have more available air space inside next to the face. For me, the ear loops are just the right degree of tightness. This style does not fog my glasses, either. For reference, I'd say I have an upper medium sized woman's face, larger than my three daughters but not nearly as large as my husband! I also love that it comes in tan, so it doesn't stand out as much on one's face.
I have a smaller face that this mask fits like a glove and the walnut color is flesh tone so it isn't as noticeable as other colors or patterns. I am also able to wear my other more decorative cloth masks over it without affecting the fit. Love Masklab.
This is a breathable, but effective mask! It doesn't hurt my ears, and is a great alternative to cloth.
