The North 5500 Series Half Mask Respirator is an economical, high-performance reusable half-mask engineered for demanding industrial, MRO, chemical handling, and paint-spray environments. Crafted from a soft, non-allergenic elastomeric polymer, the North 5500 provides a secure, comfortable seal while offering a cost-effective alternative to silicone facepieces without sacrificing seal integrity. Equipped with dual N-Series cartridge connectors, it is fully compatible with the complete range of Honeywell North® thread-on cartridges, filters, and combination elements. Its low-profile design maximizes the worker's field of vision and easily integrates under safety glasses, goggles, and face shields.
