The Dromex P3PF EN Half Mask Twin Filters are high-efficiency particulate filters designed to provide protection against fine airborne dust and other harzardous particles when used with compatible gas and vapour. Featuring P3-grade glass fibre filtration media housed in a durable retaining frame, these pre-filters offer effective particle capture while helping prevent particle contamination of underlying gas cartridges. Their lightweight, low-profile construction supports comfortable use without significantly obstructing the wearer's field of vision. Designed for use with compatible Dromex gas cartridge fitted to DH-302 half mask and DHFFM full-face respirator, they are suitable for automotive refinishing, spray painting, and other industrial applications.
