Good Manner Premium Protective Mask 5EA, Large, White/Black/Grey/Pink/Beige, Made in Korea (Grey)

My past experience has been, the way to judge the effectiveness of a mask is by how difficult it is to breathe. If you're not experiencing significant discomfort and making a lot of extra effort just to breathe, your mask isn't working! I've always had to take air breaks, where I pull the mask away and sneak in a little oxygen, but not with this mask. It's completely comfortable, so I'm suspicious. And very pleased!

Good. Real KF94s. Pretty stiff trifold

These are great masks in a nice gray color. These rated very highly on a quality test that I saw on youtube.

I have used this company in the past and like the masks. However, I was supposed to get the gray masks but they sent the pink ones instead.

These masks seem to be genuine Korean KF94 masks from the Good Manner brand. They’re the most comfortable masks I’ve had through the pandemic, don’t pull on your ears at all, and come in a bunch of colors! Highly recommend.
