Frontline 5400 Half Mask Reusable Respirator

Designed for reliable protection and all-day comfort, this NIOSH-approved half mask respirator features a bayonet-style cartridge connection that allows cartridges to twist and lock securely into place for quick, hassle-free changes. The high-quality silicone facepiece provides a soft, durable seal that resists aging and stays comfortable during extended wear.

A patented sliding front cover makes disassembly and cleaning easy, while the butterfly-shaped exhalation valve improves airflow and helps reduce heat and moisture buildup. Its ergonomic, low-profile design fits closely to the face, and adjustable head straps keep the mask securely in place. When used with compatible MK Series gas cartridges and MF Series particulate filters, it offers dependable protection against a wide range of gases, vapors, and particulates. Available in small, medium, and large, it ensures a comfortable, secure fit for different users.
