The 3M™ Secure Click™ particle insertion filter D7925, P2 R, is a lightweight filter that combines protection and comfort. Used four times (2 pieces on each side of the filter), it offers in combination with the gases/vapours filters of the D8000 series low breathing resistance and a good balance with optimum field of vision. As a combination filter, it can be quickly and easily clicked into place with the half mask series 3M™ Secure Click™ HF 800(SD). For the connection with the gases/damping filters you also need the filter cover D701. https://elecena.pl/product/28028192/3m-d7925-secure-click-p2-r-particulate-filter-4-pc 2025-03-16 https://elecena.pl/product/28028192/3m-d7925-secure-click-p2-r-particulate-filter-4-pc 2025-04-26
