I'm going to be taking this mask on my cruise in a few weeks, It's cloth but it also has a KN95 style filter and is form fitting to my face... from the little tag and the articles I guess it filters out up to 0.1 microns which is pretty good? https://www.amazon.com/gp/product/B08FXXN7JH/ref=ppx_yo_dt_b_asin_image_o01_s00?ie=UTF8&th=1
