Honeywell North 7580P100 P100 Respirator Cartridge (2-Pack)

Honeywell North 7580P100 — North 7000/5000 Series, NIOSH P100, 99.97% Oil-Proof Efficiency

The Honeywell North 7580P100 is a NIOSH-approved P100 particulate filter disc sold in a 2-pack, designed for the North 7700 series half-mask, North 7600 series full-face, and the broader North twist-lock respirator family. P100 is the highest particulate filtration class available from NIOSH under 42 CFR Part 84 — 99.97% minimum efficiency, fully oil-proof, with no time limitation in oil-aerosol environments. The 7580P100 disc mounts over North OV or combination cartridges, delivering P100 particle protection on top of chemical vapor filtration in the same respirator configuration. For full-face North respirators requiring a larger-format P100 filter, see the North 75FFP100 and the detailed comparison below.

Key Features

• P100 (99.97%) Filtration Efficiency — the highest NIOSH particulate class: P100 exceeds both N95 (95%, non-oil-resistant) and R95 (95%, oil-resistant single-shift only) at efficiency and oil resistance. The "P" designation means fully oil-proof with no single-shift time limitation — the filter maintains rated efficiency indefinitely in oil-aerosol environments. Required by OSHA for lead, asbestos (selected operations), cadmium, and other high-hazard particulate applications where N95 protection is insufficient.
• Disc-style design that stacks over OV cartridges: The 7580P100 is a filter disc, not a full cartridge. It mounts over the front of North OV, acid gas, or combination cartridges, adding P100 particle filtration on top of chemical vapor protection. This architecture allows the chemical protection level to be selected independently from the particulate protection level — a meaningful flexibility advantage in multi-hazard industrial environments.
• North twist-lock bayonet mount — fast, positive-locking: The quarter-turn engagement is quick to install and removes without tools. The mount is common across the North 7700 half-mask, North 7600 full-face, North 5500 half-mask, and North 5400 series. The North bayonet is not cross-compatible with 3M, MSA, or Moldex cartridge systems.
• Low breathing resistance at P100 efficiency: Achieving 99.97% filtration efficiency while managing inhalation resistance is the core engineering challenge of P100 filter design. Workers performing sustained physical tasks report manageable breathing resistance relative to the filtration class — a relevant factor for lead abatement, demolition, and confined space operations requiring extended wear.
• 2-pack value per box: Each box contains two filter discs — one pair for dual-cartridge half-mask platforms. At $9.37 per pair, the per-filter cost is competitive with equivalent P100 disc filters from other major brands in the same filtration class.
• Magenta NIOSH color code — visual hazard class identification: The magenta color matches the NIOSH standard color code for P100 filtration across all cartridge manufacturers. Workers, supervisors, and safety officers can confirm the correct filter class is installed at a glance during pre-use inspection — reducing the risk of mismatched filter deployment in multi-hazard environments where different cartridge types are in simultaneous use.

Applications — When to Use the 7580P100

• Lead abatement and renovation: OSHA 29 CFR 1910.1025 and 1926.62 require P100 (or PAPR equivalent) for lead exposures above established action levels. The 7580P100 satisfies the particulate requirement; for welding on lead-painted steel or operations generating organic vapors, add North OV cartridges to the respirator system. Fit testing on the specific facepiece-cartridge combination is required under OSHA 1910.134.
• Silica and construction dust: Crystalline silica (SiO₂) generated by cutting, grinding, and demolition of concrete, masonry, and stone is a Group 1 carcinogen. OSHA 29 CFR 1926.1153 and 1910.1053 require at minimum N95 half-mask protection for most silica exposures — P100 provides a meaningful safety margin above the minimum, and is the specification of choice where industrial hygiene assessment indicates elevated concentrations or conservative program management.
• Asbestos abatement (selected classifications): OSHA 29 CFR 1910.1001 and 1926.1101 specify P100 half-mask protection for certain asbestos abatement exposure classifications. Verify the required protection factor against the specific work class under the applicable standard — full-face (APF 50) may be required for Class I operations rather than half-mask (APF 10).
• Metal fume environments: Welding, torch cutting, and thermal spray operations generate metal-oxide fumes. The 7580P100 provides P100-level metal fume filtration when paired with appropriate North OV or acid gas cartridges on a North half-mask or full-face respirator platform, addressing both fume and vapor hazards in a single configuration.
• Pharmaceutical and laboratory particulate hazards: Potent compound handling, pharmaceutical API manufacturing, and laboratory environments with fine particulate hazards require P100 filtration. The oil-proof P designation is relevant where process solvents or cutting oils create aerosol conditions that would degrade N-rated filter efficiency over the course of a shift.
• General high-efficiency particulate applications: Any application where an industrial hygiene assessment specifies P100 protection, or where the employer opts for P100 as a precautionary upgrade in dust or particulate environments requiring documentation-grade compliance with OSHA 1910.134.

When P100 Is Required vs. N95 or R95

The NIOSH filtration class determines which environments a filter is approved for. Select P100 when any of the following conditions apply:

Filtration class alone does not determine compliance — APF of the facepiece platform also applies. A P100 half-mask (APF 10) is not adequate above 10× OEL regardless of filter efficiency. Verify with the applicable OSHA substance standard and your site industrial hygiene assessment.

Who Needs P100 Over N95 or R95?

The 7580P100 is the correct filter specification when any of the following apply to the work task or regulatory context:

• Workers in OSHA-regulated lead, asbestos, or cadmium programs — OSHA substance standards explicitly require P100 filtration for these hazards; N95 and R95 do not meet the specified class requirement regardless of efficiency similarity at the listed percentages
• Workers in oil-aerosol environments for multi-shift programs — oil mists, metalworking fluids, and lubricant aerosols degrade N-series filter efficiency over extended exposure; R95 is rated for single-shift oil use only; P100 is oil-proof with no time limitation
• Safety professionals specifying respirator programs with P100 as a conservative baseline — employers in high-hazard industries frequently specify P100 across all particulate operations to avoid filter class selection errors in the field, even where N95 would technically satisfy the regulatory minimum
• Workers replacing the legacy North 5580P100 — the 7580P100 is the direct successor with identical specification; any program previously specifying 5580P100 should update to 7580P100

Compatible North Respirators

The 7580P100 uses North's twist-lock bayonet mount — the same connection geometry across all North 7000 and 5000 series platforms. Verify the specific respirator's cartridge port accepts the North twist-lock system before ordering.

Always verify compatibility in the North respirator manufacturer's cartridge compatibility guide before use in a compliance program. Bayonet mount geometries are brand-specific and not interchangeable.

North P100 Filter Options — Complete Lineup

7580P100 vs. 75FFP100 — Detailed Comparison

Both are NIOSH P100 filter discs for North twist-lock respirators — the decision between them is driven by the respirator platform in use, required APF, and whether combined OV + P100 stacked protection is needed in the configuration.

Configuration selection must be based on a documented site hazard assessment. Verify the complete North cartridge lineup in the Honeywell North product catalog before specifying for a compliance program.

OSHA Compliance & Fit Testing

The 7580P100 is NIOSH approved under 42 CFR Part 84 for P100 particulate filtration. Under OSHA 29 CFR 1910.134, its use requires compliance with the general respiratory protection standard in addition to any substance-specific standard (lead, asbestos, silica) governing the work task.

• Fit testing required before operational use: OSHA 1910.134(f)(2) mandates annual qualitative (QLFT) or quantitative (QNFT) fit testing before any employee uses a tight-fitting respirator in a hazardous atmosphere. Fit testing must be conducted on the specific facepiece model and size — not on a generic respirator type. Changing cartridges to the 7580P100 disc does not trigger a new fit test if the same facepiece is used, but verify with the applicable OSHA substance standard.
• Written respiratory protection program required: OSHA 1910.134(c) requires a written program for all workplaces where respirators are used under hazardous conditions — including hazard assessment, medical evaluation procedures, fit testing schedule, training, and cartridge change-out schedule. The program must be site-specific and updated when conditions change.
• Medical evaluation before fit testing: OSHA 1910.134(e) requires a physician or licensed healthcare professional (PLHCP) to evaluate each worker's ability to use a respirator before fit testing or operational deployment. Medical clearance must be in place before the fit test is administered.
• Cartridge change-out schedule: When the 7580P100 is used in combination with North OV or gas cartridges, OSHA 1910.134(d)(3)(iii)(B)(1) requires a documented change-out schedule for the gas/vapor cartridge component based on objective industrial hygiene data or end-of-service life indicators (ESLI). Particulate-only P100 discs are replaced based on increased breathing resistance or physical damage — not a calendar schedule.
• Substance-specific standards supersede the general standard: OSHA 1910.1025 (lead), 1910.1001 (asbestos), 1910.1027 (cadmium), and 1926.1153 (silica) each specify respiratory protection requirements that may be more stringent than the general 1910.134 standard. The applicable substance standard governs when there is a conflict. Always verify the required protection factor, filter class, and APF against the specific OSHA standard before specifying equipment for a regulated program.

Frequently Asked Questions

What is the difference between P100, N95, and R95 filtration?

N95 provides 95% filtration efficiency against non-oil-based particles but has no rating for oil environments. R95 provides 95% efficiency and is oil-resistant for single-shift use only — oil exposure degrades R95 performance over extended use. P100 (this filter) provides 99.97% efficiency and is fully oil-proof with no time limitation. P100 is the highest disposable-equivalent particulate filtration rating available from NIOSH and is required by OSHA for specific high-hazard applications including lead (1910.1025), asbestos (1926.1101), and cadmium. The efficiency gap between N95 and P100 is significant in high-concentration environments where the 5% inefficiency of N95 represents a meaningful dose increment.

Which North respirators are compatible with the 7580P100?

The 7580P100 uses North's twist-lock bayonet mount and is compatible with the North 7700 series half-mask, North 7600 series full-face, North 5500 series half-mask, and North 5400 series full-face respirators, along with other North platforms using the same twist-lock system. It is not compatible with 3M bayonet cartridges, MSA cartridges, or other brands' cartridge systems. Always verify compatibility in the respirator manufacturer's cartridge compatibility guide before use in a compliance program.

How does the 7580P100 differ from the North 75FFP100?

Both are NIOSH P100 filters for North respirators using North's twist-lock mount, but they differ in geometry and platform compatibility. The 7580P100 is a smaller disc-style filter for the North 7700 half-mask and 5000-series respirators; it stacks over OV or combination cartridges for combined protection. The 75FFP100 is a larger-format filter designed for specific full-face platforms with a different filter face area and lower breathing resistance at equivalent efficiency. See the detailed comparison table above for a full spec-by-spec breakdown.

Does the 7580P100 protect against chemical vapors and gases?

No. The 7580P100 is a particulate-only filter disc. It contains no activated carbon or absorbent media for organic vapor, acid gas, or other chemical protection. In environments where both particulate and chemical hazards are present — welding fumes plus solvent vapors, lead dust plus acidic mists, silica dust plus isocyanates — the 7580P100 must be stacked on top of the appropriate North chemical cartridges. Organic vapor cartridges go underneath; the 7580P100 disc mounts over them to add P100 particle filtration.

When should the 7580P100 filter be replaced?

Replace the 7580P100 when breathing resistance increases noticeably during use, when the filter is physically damaged, or when it becomes wet from perspiration or liquid splash — wet filter media increases resistance and may allow wicking. Unlike gas/vapor cartridges, P100 particulate filters have no chemical end-of-service-life indicator because they do not absorb chemicals. Service life depends on particle loading rate, which varies by environment. Employers should establish change-out intervals based on industrial hygiene assessment data. OSHA 1910.134(d)(3)(iii) requires replacement before use when damaged or contaminated.

What does the magenta color on the 7580P100 mean?

Magenta is the NIOSH standardized color code for P100 filtration. This color convention applies across all cartridge manufacturers — magenta always indicates P100 (99.97% efficiency, oil-proof) on NIOSH-certified products. Workers, supervisors, and safety officers can visually confirm the correct filter class is installed on a respirator during pre-use inspection without reading the label. In multi-hazard environments where different cartridge classes are in simultaneous use, color coding reduces the risk of mismatched filter installation.

Is the 7580P100 approved for lead paint removal?

The 7580P100 meets the P100 particulate filtration requirement for lead exposure under OSHA 1910.1025 and 1926.62 when used in a NIOSH-approved North respirator configuration. For lead paint removal operations involving heat, torch, or sanding that generate organic vapors or combustion byproducts, pair the 7580P100 with the appropriate North OV cartridges on a North respirator platform. The complete respirator must be fit-tested on the specific worker before use in any lead program under OSHA 1910.134.

What is the Assigned Protection Factor for a P100 half-mask respirator?

OSHA assigns an APF of 10 to all half-mask respirators — the P100 filter class does not change this facepiece APF. A properly fit-tested half-mask with P100 filters is expected to reduce worker exposure to 1/10 of ambient concentration. For exposures above 10× the OSHA PEL, a full-face respirator (APF 50) or PAPR (APF 1,000) is required regardless of filter class. The 7580P100 used on a North 7600 full-face delivers APF 50. OSHA Table 1 in 29 CFR 1910.134 Appendix B is the authoritative reference for APF assignments.

Does using the 7580P100 require fit testing?

Yes. OSHA 29 CFR 1910.134(f) requires qualitative or quantitative fit testing before any employee uses a tight-fitting respirator in a hazardous atmosphere. Fit testing is conducted on the specific facepiece model and size — not the cartridge. Annual re-testing is required, plus whenever a different facepiece model or size is used. Switching from a different P100 disc to the 7580P100 on the same facepiece does not require a new fit test, but adding stacked cartridges that alter facepiece geometry may warrant re-evaluation with the program administrator.

Can the 7580P100 be used with a PAPR?

No. The 7580P100 disc filter is designed for North tight-fitting elastomeric respirators only. Powered air-purifying respirators (PAPRs) use proprietary filter modules that are specific to each PAPR blower unit and hood or helmet system — they are not compatible with tight-fitting bayonet filter disc systems. If P100 protection is required with a PAPR, specify the appropriate P100 filter module from the PAPR manufacturer. PAPRs with P100 filters provide APF 1,000 — significantly higher than the APF 10–50 of tight-fitting respirators — and are the correct choice for high-concentration exposures exceeding 50× OEL.

How does the 7580P100 price compare to equivalent P100 filters?

At $9.37 per 2-pack, the 7580P100 is competitively priced relative to equivalent disc-style P100 filters from 3M and other major brands. All NIOSH P100 filters provide identical minimum efficiency — 99.97% — so filtration performance is not a differentiating factor. The practical differentiation is mount system compatibility. Compare price per pair within the compatible brand ecosystem; North and 3M bayonet systems are not interchangeable, making cross-brand price comparison relevant only for programs considering full platform transitions.

Is the 7580P100 the same as the North 5580P100?

Yes, functionally. The 7580P100 is the updated replacement for the legacy North 5580P100 filter disc. Honeywell North updated product numbering during the Honeywell-North Safety branding consolidation. The 7580P100 maintains the same P100 filtration specification and North twist-lock mount geometry as the predecessor 5580P100 — the specification and form factor are unchanged. Programs or purchase orders previously specifying the 5580P100 should update to 7580P100; no change to the respirator platform or compliance documentation is required.

Where can I find compatible North OV cartridges to stack with the 7580P100?

North OV, acid gas, and combination cartridges for the North twist-lock bayonet system are available through Honeywell North authorized distributors and direct from Honeywell. For disposable P100 respiratory protection, the Honeywell SAF-T-FIT Plus P100 disposable respirator is an alternative for applications where a reusable elastomeric platform is not required.
