It uses the North bayonet cartridge system — compatible with the full North cartridge library including OV, AG, P100, combination, and mercury vapor cartridges. The 5500 delivers the same NIOSH compliance and North bayonet cartridge access as the premium 7700 series at a lower price point — the right choice when the 7700's low-profile welding-helmet feature is not required. Select medium after OSHA-required fit testing confirms it as the correct size — medium is the recommended starting size for most workers.\u003c\/p\u003e\n\n\u003ch2\u003eHoneywell North 550030M Half Mask Respirator — Medium | North 5500 Series\u003c\/h2\u003e\n\n\u003cp style=\"font-size:0.9em;color:#999;margin-top:-8px;\"\u003e\u003cstrong\u003eReviewed by the WC Safety Editorial Team\u003c\/strong\u003e — PPE specialists with hands-on experience across industrial, construction, chemical, and healthcare environments. \u003cem\u003eLast updated: May 2026.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eHoneywell North 550030M\u003c\/strong\u003e is the medium-size half-mask respirator in the \u003cstrong\u003eNorth North 5500 Series\u003c\/strong\u003e.

The 5500 provides the same compliance at a lower price point and is the right choice when the 7700's low-profile welding feature is not required.
