This Moldex 7000 series half mask respirator comes pre-assembled with multi-gas/vapor cartridges. Buying pre-assembled is convenient and reduces error when selecting cartridges. The 7000 series respirators features a sleek, lightweight design that workers won’t mind wearing. The face piece is designed to comfortably fit facial contours and the adjustable head cradle ensures a custom fit. Put the dual mode strap in drop down mode to hang around the neck when not in use or switch to lock down mode to quickly put on the mask with no need to readjust the fit. Combine the multi-gas/vapor cartridges with #8910 N95, #8970 R95, or #8940 P100 filters to also protect against particulates.
