It uses the North bayonet cartridge system, compatible with the complete North cartridge library. The polycarbonate lens provides eye and face protection against splash and mist, eliminating separate chemical goggles in most chemical exposure environments.

For direct immersion in concentrated acids, verify lens chemical compatibility with the product datasheet for your specific exposure.\u003c\/p\u003e\n\n\u003ch3 style=\"margin-bottom:6px;\"\u003eHow does the 54001 compare to the 760008A?\u003c\/h3\u003e\n\u003cp style=\"margin-top:0;\"\u003eBoth carry NIOSH TC-14C approval and APF 50 — the compliance standing and protection level are identical. The 7600 series offers premium silicone, 5-strap harness, and enhanced full-shift comfort — the upgrade is in durability and comfort, not in protection level.

For P100 filters, replace when breathing resistance increases noticeably or upon physical damage. For vapor and combination cartridges, use Honeywell's service life estimation tools based on contaminant, concentration, temperature, humidity, and shift length. End-of-shift replacement is the conservative standard in high-hazard environments.

Wash with mild soap and warm water; rinse thoroughly. Use an approved disinfectant and allow to air dry — do not use solvents or bleach on the silicone face seal or polycarbonate lens. Inspect the face seal, exhalation valve, head harness, and lens before each use. Replace the lens if it shows crazing, cloudiness, or surface degradation that impairs visibility or seal integrity. Write lens inspection and replacement into your respiratory protection program.\u003c\/p\u003e","brand":"Honeywell North","offers":[{"title":"Small","offer_id":44165814386776,"sku":"54001S","price":124.99,"currency_code":"USD","in_stock":true},{"title":"Medium\/Large","offer_id":44165814419544,"sku":"54001","price":146.24,"currency_code":"USD","in_stock":true},{"title":"Small Welding","offer_id":44165814452312,"sku":"54001SW","price":305.22,"currency_code":"USD","in_stock":true},{"title":"Medium\/Large Welding","offer_id":44165814485080,"sku":"54001W","price":318.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0594\/1900\/0920\/files\/sps-his-new-5400_ad5ca3e0-9d7d-4774-8b97-2ca5a4b037c7.webp?v=1774136795","url":"https:\/\/wcsafety.com\/products\/honeywell-north-5400-series-full-face-respirator-54001s-54001m-l","provider":"WC Safety","version":"1.0","type":"link"}
