When you say a KN95 barely protects the user at all, are you stating that they are worse than a cloth/surgical mask? I recently purchased some kn95's to wear in

When you say a KN95 barely protects the user at all, are you stating that they are worse than a cloth/surgical mask? I recently purchased some kn95's to wear instead of the surgical masks when these variations started to pop up.
- superkuh 6y agoSorry, I didn't meant to imply all KN95 are bad. I only mean the specification means very little in north america and of all the KN95 masks I have tried they have too high of a pressure drop across the actual filter to do filtering. When I use medical tape to seal them to my face they puff out and suck in dramatically. A low pressure drop N95 mask, when sealed with medical tape will barely move. You can even feel drafts from air conditioning through it. What I am saying is that KN95 types in the USA are of such variably quality they are not a good choice. Use local standards and brands.
