I received my KN95 masks today. I like that the elastic on these is strong. Also, good quality on the inside. These are a bit of an adjustment of you're used to wearing protective masks with vents on the side, as the air isn't flowing out as easy.

These seem to give much more protection than other masks. They also fit better, not needing the constant adjustment if the other masks.

I have ordered six different Brands of KN95s off. This is my favorite. It is the best bang for your buck. It does a pretty good job at preventing fog on my glasses. It is individually wrapped in packs of five which is convenient to keep masks in different places and give some to family members.
