We bought two brands of KN95s from Taobao, and I've found they don't fit my caucasian face very well. The bend strip around the nose is too short to get a good seal.
This was earlier in the pandemic, and I believe they were off-brand ones, so they might be lower quality than others. We definitely didn't pay that much. I only consider them a marginal improvement over a surgical mask.
Only for use in healthcare settings. The FDA doesn't have regulatory authority over masks and respirators for non-medical uses.
