JSP Press To Check P3 particulate filter

Replacement filters for JSP half-face or full-face masks. P3 particulate filters protect the respiratory tract against hazardous solid and liquid particles, such as dust and microorganisms (including bacteria and viruses). Particulate filters do not protect against gases or vapours. Press To Check filters make it possible to check the mask-to-face seal: squeezing the filters blocks airflow through them, so no air should enter the mask when inhaling if the mask fits tightly and correctly. If air does enter, adjust the facepiece until the seal is airtight. Pack contains one pair of filters.
