Honeywell North 7580P100 P100 Particulate Filter Cartridge (2-Pack)

Honeywell North 7580P100 — North Bayonet P100 Particulate Filter, NIOSH 42 CFR 84, 2-Pack

The Honeywell North 7580P100 is a NIOSH 42 CFR 84 P100 particulate filter delivering 99.97% filtration efficiency against all NIOSH-defined particle types — sold as a 2-pack for the North bayonet connector system. The 7580P100 provides particulate protection only; for environments where gas or vapor hazards are also present, pair it with a gas cartridge or choose a combination cartridge such as the 7581P100L (OV+P100), 7583P100L (OV+AG+P100), or 75SCP100L (multi-contaminant). If you need a single-unit replacement rather than a 2-pack, see the 75FFP100. Fits all Honeywell North 7700, 5500, 5400, and 7600 series respirators.

Key Features

• NIOSH P100 — 99.97% efficiency: The highest NIOSH particle filtration class — 99.97% efficiency against all aerosol types regardless of oil content. Correct for OSHA silica, asbestos, lead, and other NIOSH-regulated toxic dust standards where a P100 is specified or required
• 2-pack value: The 7580P100 ships as a pair — covering both cartridge positions on a standard North half-mask or full-face respirator in a single purchase, with cost-per-filter advantage over single-unit replacements
• North bayonet connector: Snap-and-twist bayonet attachment compatible with the full North respirator lineup — 770030, 550030, 54001, and 760008 series facepieces
• Low breathing resistance: P100 filter media is engineered for low differential pressure across the filter face, reducing inhalation effort during extended operations compared to higher-resistance filter grades
• Broad particle coverage: P100 classification covers oil-based aerosols (cutting fluids, metalworking coolants), non-oil-based dusts (silica, concrete, asbestos, lead), biological aerosols, and fumes — a single filter class eliminates the need to specify oil resistance separately

Applications — When to Use the 7580P100

The 7580P100 is the correct filter when the confirmed workplace hazard is particulate only — no gas or vapor co-exposure. Common OSHA-regulated applications include:

• Respirable crystalline silica: OSHA 29 CFR 1910.1053 / 1926.1153 — P100 on a half-mask provides APF 10; P100 on a full-face provides APF 50. Use the full-face when air monitoring shows concentrations above 10× the AL (0.025 mg/m³)
• Asbestos (Class III and IV work): 29 CFR 1910.1001 specifies P100 or higher for Class III (repair/maintenance) and Class IV (custodial) operations. Class I and II require full-face or PAPR
• Lead dust and fume: OSHA 1910.1025 — P100 on a half-mask for lead at concentrations up to 10× PEL (500 µg/m³); P100 on full-face for up to 50× PEL (2,500 µg/m³)
• Welding fume (without gas co-exposure): When confirmed that only metal fume is present (no cadmium, Cr VI, or CO co-exposure) — P100 filter controls the particle hazard
• Coal dust, grain dust, wood dust: Nuisance or regulated dust environments without gas hazards — P100 exceeds the N95 minimum and provides margin for concentration variability
• Mold remediation: EPA/OSHA mold guidelines specify N95 minimum; P100 is appropriate for large-scale or high-concentration remediation operations

Important: The 7580P100 provides no protection against gases or vapors. If your SDS or industrial hygiene assessment identifies solvents, acids, ammonia, or other vapor co-exposure, select a combination cartridge such as the 7581P100L or 75SCP100L.

Compatible Respirators

All Honeywell North 7-series and N-series cartridges use the North bayonet twist-lock connector, compatible with the following facepieces. Cartridge selection does not affect fit testing — OSHA 1910.134(f)(2) requires annual fit testing for any tight-fitting respirator.

North Cartridge & Filter Line — Full Comparison

All Honeywell North cartridges use the same North bayonet connector. Select based on documented hazard class — cartridge type does not change the facepiece.

OSHA Compliance

• NIOSH approval required: All cartridges used in OSHA-mandated respiratory protection programs must be NIOSH approved under 42 CFR Part 84 — Honeywell North cartridges carry NIOSH approval for the hazard classes listed on the cartridge label
• Cartridge selection via hazard assessment: OSHA 1910.134(d)(1) requires selecting a respirator and filter/cartridge based on a workplace hazard assessment — cartridge type must be confirmed by a Certified Industrial Hygienist or equivalent documentation
• Fit testing required: OSHA 1910.134(f)(2) mandates annual fit testing for any tight-fitting facepiece — changing cartridges does not reset the fit test requirement
• Change schedules required: OSHA 1910.134(d)(3)(iii) requires an established cartridge change schedule for gas/vapor cartridges — end-of-service-life must be determined before use, not when breakthrough is detected by smell
• Medical evaluation prerequisite: OSHA 1910.134(e) requires medical clearance before fit testing or operational respirator use — this applies regardless of cartridge type selected

Frequently Asked Questions

What does the 7580P100 protect against?

The 7580P100 is a P100 particulate filter providing 99.97% efficiency against all aerosol types — silica dust, asbestos fibers, lead fume, coal dust, welding fume, mold spores, metal dust, and biological aerosols. It provides no protection against gases or vapors. If solvents, acids, ammonia, or other vapors are present, a combination cartridge is required.

What is the difference between the 7580P100 and 75FFP100?

Identical NIOSH protection and filter media. The 75FFP100 is a single filter unit; the 7580P100 is a 2-pack. For a two-cartridge respirator (standard for North half-masks and full-face units), the 7580P100 covers both positions in one purchase. The 75FFP100 is used when replacing only one filter independently.

Which North respirators does the 7580P100 fit?

All Honeywell North bayonet-equipped respirators: North 770030 series (S/M/L), North 550030 series (S/M/L), North 54001 (M/L) and 54001S, North 760008A (M/L) and 760008AS. Not compatible with 3M, MSA, Moldex, or other brands.

Is the 7580P100 the same as an N95?

No — P100 is substantially more efficient. P100 filters ≥99.97% of all particles regardless of oil content. N95 filters ≥95% of non-oil-based particles only and fails if oil aerosols are present. P100 is the correct choice for OSHA-regulated silica, asbestos, and lead programs where an APF 10 cartridge respirator is appropriate.

How do I know when to replace the P100 filter?

P100 filters are replaced when they are physically damaged, visibly contaminated, or when breathing resistance increases noticeably — not on a fixed time schedule. Unlike gas cartridges, P100 filters do not have chemical end-of-service-life. Establish a written replacement schedule per OSHA 1910.134(d)(3)(iii) based on your task conditions.

Can I add a gas cartridge to the 7580P100 for vapor protection?

No — the 7580P100 is a standalone P100 filter without a gas-sorbent layer. To protect against both particles and gas/vapor simultaneously, select a combination cartridge that integrates both: 7581P100L (OV+P100), 7583P100L (OV+AG+P100), or 75SCP100L (OV+AG+NH₃+P100).

Is fit testing required when using the 7580P100?

Yes — OSHA 1910.134(f)(2) requires annual fit testing for any tight-fitting facepiece before operational use. Fit testing is tied to the facepiece, not the cartridge. Changing from N95 prefilters to P100 cartridges does not reset or change the fit test requirement.

Does P100 protect against asbestos?

Yes. OSHA 1910.1001 specifies P100 filtration for asbestos Class III and Class IV work on a half-mask (APF 10). For Class I and II asbestos operations, a full-face respirator or PAPR with APF 50 or greater is required. The North 54001 with 7580P100 provides APF 50 and is appropriate for Class I/II with air monitoring confirmation.

Are North cartridges compatible with 3M respirators?

No — North bayonet cartridges are not compatible with 3M, MSA, Moldex, or any other brand. Each manufacturer uses a proprietary cartridge-to-facepiece connection. Only use North cartridges with North-bayonet-equipped facepieces.

What is the APF when using the 7580P100 on a full-face respirator?

APF 50. A NIOSH-approved P100 filter on a properly fit-tested full-facepiece respirator (North 54001 or 760008 series) carries an APF of 50 under OSHA 29 CFR 1910.134 Appendix A — 5× the APF 10 of a half-mask. This allows use in environments up to 50× the OEL for the covered hazard class.

Can I use the 7580P100 for welding fume?

Yes, for metal fume alone. However, if welding involves cadmium, hexavalent chromium (Cr VI), manganese, or produces CO gas, a P100-only filter is insufficient. Cr VI welding (e.g., stainless steel) requires a combination cartridge or engineering controls. Consult your industrial hygiene assessment before selecting cartridge type for welding operations.
