Who the Honeywell North 7580P100 Is For

The Honeywell North 7580P100 is designed for workers whose only airborne hazard is particulate matter no solvent vapor, no acid gas, no ammonia.

• Asbestos abatement contractors OSHA 1926.1101 and 1910.1001 require minimum half-mask P100 for Class IIII operations
• Silica and concrete grinders OSHA 29 CFR 1910.1053 silica standard; P100 maximizes available APF at the half-mask level
• Lead abatement workers 29 CFR 1910.1025 specifies half-mask P100 minimum at elevated lead exposures
• Welders and metal fabricators welding fume (manganese, Cr VI in stainless welding) is a P100-appropriate particle hazard
• Pharmaceutical powder handlers active-ingredient particles in tablet coating, powder transfer
• Radionuclide handlers DOE/NRC facilities require NIOSH P100 for radioactive particle work

When gas or vapor hazards are also present, see Honeywell North 7581P100L (OV+P100) or Honeywell North 75SCP100L (OV+AG+AM+P100) for full multi-hazard coverage.

Honeywell North 7580P100 Performance: What It Does Well

NIOSH P100 99.97% Efficiency, Highest Available Class

Approved under NIOSH 42 CFR 84 Subpart K, the 7580P100 achieves 99.97% filtration efficiency at the most penetrating particle size (~0.3 m) exceeding N95 (95%), R95 (95%), N99 (99%), and P99 (99%). For OSHA-regulated hazards with no safe exposure level, P100 is the ceiling of half-mask protection.

Oil-Proof P-Class Stability

P-class filters maintain their rated efficiency indefinitely in oil aerosol environments. N-class electrostatic filters can degrade on contact with oils. In metalworking with coolant mist or food processing with oil-based aerosols, the 7580P100's P-class rating is essential.

Lightweight: No Sorbent Weight

Without a chemical sorbent bed, the 7580P100 is significantly lighter than any combination cartridge, reducing jaw and neck fatigue in multi-hour shift work.

Best Per-Filter Value in the North P100 Line

At ~$5.75/filter (2-pack), the 7580P100 delivers P100 protection at roughly half the per-unit cost of the Honeywell North 75FFP100 single unit (~$9.94). For regular users, the 2-pack is the obvious economic choice.

Limitations: Where the Honeywell North 7580P100 Falls Short

No Gas or Vapor Protection

The 7580P100 provides zero protection against organic vapors, acid gases, or any gaseous contaminant. For spray painting (solvent vapor) or acid environments, step up to Honeywell North 7581P100L or Honeywell North 75SCP100L.

No End-of-Service-Life Indicator

Particle filters signal replacement only via increased breathing resistance. OSHA 1910.134(d)(3)(iii) mandates replacement when resistance makes breathing difficult train workers to recognize this signal and enforce per-shift replacement in high-risk operations.

Half-Mask APF 10 Ceiling

On any half-mask, APF is 10 per OSHA 29 CFR 1910.134 Appendix A. For exposures above 10 OEL, move to the North 7600 full-facepiece with the same 7580P100 filter (APF 50).

AG = Acid Gas AM = Ammonia/Methylamine APF 10 for all half-mask configurations. Price estimates May 2026.

Compatible Respirators for the Honeywell North 7580P100

The 7580P100 fits all North bayonet-mount respirators:

• North 7500 Series half-masks 7501 (Small), 7502 (Medium), 7503 (Large)
• North 5500 Series half-masks
• North 7600 Series full-facepieces APF 50 when greater protection is needed

Not compatible with: 3M 6000/7000 series, MSA Advantage, Moldex 7000, or any non-North respirator. North's bayonet mount is proprietary.

Replacement Schedule & Service Life

Replace when breathing resistance increases noticeably, per OSHA 29 CFR 1910.134(d)(3)(iii).

• Asbestos abatement: After every shift asbestos fibers can dislodge from loaded filters during doffing
• Lead abatement: Per shift; wash hands and face before eating
• Silica grinding: When resistance increases, or per shift in heavy exposure
• General construction dust: When resistance is noticeable; weekly minimum for daily use

Store sealed in original packaging away from chemical vapors and high humidity.

Final Verdict: Honeywell North 7580P100 P100 Particulate Filter

The Honeywell North 7580P100 earns 4.6/5: NIOSH P100 at 99.97% efficiency, oil-proof, lightweight, and outstanding value at ~$5.75/filter in the 2-pack format. For particle-only hazards on North bayonet respirators, it is the definitive choice.

When vapor or gas hazards join the picture, step up to Honeywell North 7581P100L (OV+P100) or Honeywell North 75SCP100L for the broadest North-line coverage at the best price.

Frequently Asked Questions Honeywell North 7580P100

What does the Honeywell North 7580P100 protect against?

The 7580P100 is a NIOSH P100-rated particle filter providing 99.97% filtration efficiency against asbestos fibers, crystalline silica, lead dust and fume, welding fume (including manganese and hexavalent chromium), pharmaceutical powder, radionuclide particles, and oil-based aerosols. It provides no protection against gases or vapors.

Is the 7580P100 NIOSH approved?

Yes. Approved under NIOSH 42 CFR 84 Subpart K at 99.97% filtration efficiency. Verify the current TC approval number at cdc.gov/niosh/npptl.

What respirators does the 7580P100 fit?

All Honeywell North bayonet-mount respirators: North 7500 Series half-masks (7501, 7502, 7503), North 5500 Series half-masks, and North 7600 Series full-facepieces. Not compatible with 3M, MSA, or Moldex respirators.

What is the difference between 7580P100 and 7581P100L?

The 7580P100 is a particle-only P100 filter. The 7581P100L adds an organic vapor sorbent layer, protecting against solvents, paint vapors, and lacquers in addition to particles. Use 7580P100 for particle-only hazards; use 7581P100L when vapors and particles are both present.

What is the difference between 7580P100 and 75FFP100?

Both provide identical NIOSH P100 filtration. The 7580P100 is sold as a 2-pack (~$11.49, ~$5.75/filter) and the 75FFP100 is sold as a single unit (~$9.94). The 2-pack offers significantly better value for regular users.

Can the 7580P100 be used for asbestos removal?

Yes. OSHA 1926.1101 and 1910.1001 require a minimum of a half-mask with P100 filters for Class IIII asbestos abatement. The 7580P100 on a North 7500 half-mask meets this requirement at APF 10. For APF 50, use the North 7600 full-facepiece with the same filter.

How often should I replace the 7580P100?

Replace when breathing resistance increases noticeably, when the filter is physically damaged, or after each shift for asbestos or lead abatement. There is no chemical end-of-service-life indicator increased inhalation effort is the replacement signal.

Does the 7580P100 work against lead dust?

Yes. P100 filters meet the OSHA 29 CFR 1910.1025 half-mask P100 requirement for lead abatement at 99.97% efficiency. Replace per shift and wash hands and face before eating to prevent secondary lead ingestion.

Is the 7580P100 oil-resistant?

Yes. P-class filters maintain 99.97% efficiency in oil-based aerosol environments indefinitely, unlike N-class filters which can degrade on contact with oils. The 7580P100 is appropriate for metalworking with coolant mist and oil-aerosol environments.

What is the APF for the 7580P100 on a North 7500 half-mask?

APF 10 per OSHA 29 CFR 1910.134 Appendix A, meaning use up to 10 the occupational exposure limit. For exposures above 10 OEL, use the North 7600 full-facepiece with the 7580P100 for APF 50.

Does the 7580P100 meet OSHA requirements?

Yes. NIOSH-approved and meets OSHA 29 CFR 1910.134 requirements. Satisfies the P100 requirement in OSHA standards for asbestos (1910.1001), lead (1910.1025), silica (1910.1053), cadmium (1910.1027), and hexavalent chromium (1910.1026) at the half-mask APF 10 level.
