Honeywell North Half Mask Respirator

Two Decisions. Six Models. One Honeywell North Half-Mask for Every Worker.

NIOSH TC-23C | APF 10 | North Bayonet Cartridge | Fit Test Required

The North 770030L is the best Honeywell North half-mask for most workers — 353 Amazon reviews averaging 4.85 stars, premium silicone facepiece, and dual exhalation valves. If cost is the priority, the North 550030M delivers the same NIOSH TC-23C approval and North bayonet cartridge compatibility for under $18. Two decisions determine which of these six models you need: facepiece material (silicone 7700 series vs. TPE 5500 series) and size (small, medium, or large — confirmed through a mandatory fit test). All six models are OSHA-compliant at APF 10 and accept every North 75-series cartridge and filter without adapters.

Quick Picks — All 6 North Half-Mask Models at a Glance

All six models: NIOSH TC-23C | APF 10 | North bayonet dual cartridge | Fit test required before occupational use.

Decision 1 — Facepiece Material: 7700 Silicone or 5500 TPE?

The North 7700 series (770030S, 770030M, 770030L) uses a soft silicone facepiece — UV-stable, chemically resistant, and capable of maintaining fit-test seal quality across hundreds of cleaning cycles. The dual exhalation valves reduce CO₂ buildup and exhalation resistance during high-activity tasks. For workers wearing a respirator every workday, silicone pays back its price premium through extended service life. The North 5500 series (550030S, 550030M, 550030L) uses thermoplastic elastomer (TPE) at roughly half the cost. Same NIOSH TC-23C approval, same APF 10, same North bayonet cartridges — the trade-off is facepiece longevity and single-valve exhalation. For high-headcount programs, scheduled replacement intervals, or occasional use, the 5500 TPE series is the rational choice.

Decision 2 — Size: Small, Medium, or Large?

OSHA 29 CFR 1910.134(f)(2) mandates a successful fit test before any worker wears a tight-fitting respirator occupationally — size selection is confirmed through qualitative (QLFT) or quantitative (QNFT) fit testing, not appearance or body size. Start with medium (770030M or 550030M): it fits the majority of adult workers. If medium fails fit testing, move to large (770030L or 550030L). If medium is too loose at the chin or temples, evaluate small (770030S or 550030S). Annual retesting is required, along with retesting after dental work or significant facial changes. Employers must complete a medical evaluation under 1910.134(e) and maintain a written respiratory protection program under 1910.134(c) before any respirator is used.

Decision 3 — Cartridges: One System for All Six Facepieces

Every Honeywell North half-mask and full-face respirator uses the same North bayonet dual-cartridge mount. All six half-mask models accept every North 75-series cartridge and filter without adapters — N75001 (OV), N75002 (AG), N75003 (OV/AG), 75FFP100 (P100), N750014 (OV/P100), N75021 (OV/AG/P100), and the 75SCP100L Super Combo. North bayonet cartridges are not compatible with 3M, MSA, Moldex, or any other manufacturer. See the complete selection at Honeywell North Respirator Cartridges & Filters.

When APF 10 Is Not Enough: Half-mask respirators are rated APF 10 — appropriate when airborne concentrations are confirmed below 10× the Occupational Exposure Limit. When concentrations reach 11–50× the OEL, when a simultaneous eye splash or vapor hazard exists, or when OSHA regulations specifically require full-face (Class I asbestos, certain HAZMAT operations), upgrade to the Honeywell North Full Face Respirator (NIOSH TC-14C, APF 50). All North half-mask cartridges transfer directly — no cartridge program change required.
