I have recently acquired a full-face respirator as part of my preps that is very similar to the type used by police. Since I live in the country, my primary philosophy of use is protection against tear gas. My question is, what type of filter do I need? There are a lot of different types that fit this mask, and I have the NIOSH chart that came with the mask, but no where does it list "capsasin". So, for any chemists, or cops, what type of filter do I need? Attachment 1155
