There are three types of masks that are considered to be better than the disposable 3 and 4 ply masks:
N95
KN95
KF94
The 3 and 4 ply masks are supposed to be better than cloth masks. I have seen articles recommending not to wear cloth masks before.
N95 is considered to be the best. I only tried one once. It was not easy to breathe and I didn’t like the straps that went around my head. KN95s look similar but have ear straps. I wore a KF94 yesterday and it was comfortable.
This is a good source of all kinds of PPE. I haven’t ordered from them but they get praise in the articles.
Project N95 – The National Clearinghouse for personal protective equipment and COVID-19 tests.
Two US companies I have ordered from with high quality and higher prices are:
Art-Inspired Clothes, Accessories, Face Masks & Decor | VIDA (shopvida.com)
Private Stock Labs – Privatestocklabs
Private Stock has faster shipping. Amazon has fast shipping and lower prices but I have read they have fakes as well as real stuff.
Sad!
