Honeywell North 7580P100 vs 75SCP100L: P100 Filter vs Multi-Gas

Reviewed by the WC Safety Editorial Team — Last updated: June 2026.

These two Honeywell North filters sit at opposite ends of the range: the 7580P100 is particulate only, while the 75SCP100L adds broad gas and vapor protection. The decision is whether you face any gas or vapor at all. This guide compares the North 7580P100 and North 75SCP100L by contaminant, application, the limits of each and Honeywell North respirator compatibility — start with our Honeywell North cartridge guide if you want the full lineup. Getting this right matters: an under-rated cartridge leaves a real exposure gap, while an over-rated one adds cost, weight and breathing resistance you do not need, so the goal is the narrowest cartridge that fully covers your hazard.

Quick Answer

Best Choice Summary

Best for particulate-only work: the 7580P100 — lighter and lower cost. Best for mixed gas, vapor and dust: the 75SCP100L, the broadest single Honeywell North P100 cartridge. There is a large capability gap between them, so match it to your actual hazard.

What Each Cartridge Protects Against

North 7580P100: particulate at the P100 level only — dust, mist, fume, lead, respirable silica and mold spores. It provides no gas or vapor protection.

North 75SCP100L: a broad multi-contaminant range — organic vapor, acid gases, ammonia, methylamine and formaldehyde — plus particulate at the P100 level. Honeywell rates it for more contaminants than the 7583P100L. For a primer on the rating system, see how to choose a respirator cartridge.

Key Differences

The 7580P100 stops particulate at the P100 level and nothing else. The 75SCP100L includes that same P100 filter and adds a broad multi-contaminant sorbent — organic vapor, acid gases, ammonia, methylamine and formaldehyde. The gap is large: one is a dust filter, the other is a near-complete gas-and-particulate cartridge. The 75SCP100L is heavier and costs more for that breadth.

Which One Should You Choose?

Decide by whether any gas or vapor is in the air. For dry, dusty work — sanding, grinding, demolition, silica, lead, mold — the 7580P100 is correct and economical. For painting, chemical handling, water treatment or any mixed exposure, the 75SCP100L is the safe choice because the 7580P100 provides no gas protection at all. When in doubt about gases, do not rely on the particulate filter.

Best Applications

7580P100 — best applications: Drywall and concrete dust, grinding and cutting fume, lead-paint abatement, silica work and mold remediation — wherever the hazard is particulate only. See the 7580P100 review for a closer look.

75SCP100L — best applications: Spray painting, chemical handling, water and wastewater treatment, maintenance and emergency response — any task mixing gases or vapors with particulate. See the 75SCP100L review for details.

When Not to Use Each Option

Do not use the 7580P100 where any gas or vapor is present — it is particulate only. Use the 75SCP100L only against the contaminants on its NIOSH approval, and confirm concentrations are within its limits. Neither should be used in oxygen-deficient atmospheres or where the contaminant or its concentration is unknown.

Compatibility with Honeywell North N-Series Respirators

Both the 7580P100 and 75SCP100L use the Honeywell North bayonet connection and fit the North N-series cartridge respirators: the 5500 and 7700 series half masks and the 5400 and 7600 series full facepieces. They are not interchangeable with 3M bayonet or 3M Secure Click respirators. Always confirm the NIOSH approval number on the package matches your facepiece and assembly.

Related Cartridge Alternatives

Between these extremes sit the 7581P100L (organic vapor + P100) and 7583P100L (organic vapor, acid gas + P100); choose one of those if your gas hazard is narrower than the full multi-contaminant range.

Cost, Weight and Practical Considerations

Beyond protection, three practical factors separate these Honeywell North options: cost, weight and breathing resistance. The rule across the North range is consistent — the more a cartridge protects against, the more it costs and the heavier it sits on the facepiece. A standalone P100 particulate filter is the lightest and cheapest; adding organic vapor, then acid gas, then a full multi-contaminant sorbent each raises the price and the bulk. Every option carrying a “P100” designation also bonds a particulate filter to the sorbent, which adds some breathing resistance compared with a gas-only cartridge.

The buying principle that follows is simple: choose the narrowest cartridge that fully covers your contaminants. Buying more protection than your hazard assessment requires wastes money and adds weight and breathing effort you will feel over a shift; buying less leaves a real exposure gap. For crews that switch between tasks, a single broader cartridge can simplify stock and training even if it is heavier — but that is an inventory decision, not a protection shortcut. When wear time and comfort matter, a lighter, more targeted cartridge with scheduled changes is often the better call.

Service life is the other variable. None of these cartridges has a fixed hours rating: a P100 filter is replaced when breathing resistance climbs or it is soiled, while the gas and vapor sorbent must be changed on a documented schedule before breakthrough. Higher contaminant concentration, humidity and workload all shorten life. A broader multi-contaminant cartridge does not necessarily last longer — its sorbent is shared across more chemistries — so plan changes around your measured exposure, not the cartridge's breadth.

Final Recommendation

For particulate-only work the 7580P100 is the right, economical Honeywell North filter; the moment any gas or vapor is present, move to the 75SCP100L for broad multi-contaminant plus P100 protection, or a narrower OV/acid-gas cartridge if that matches your hazard. Confirm your selection against a documented exposure assessment and the Honeywell North cartridge guide.

Safety note: Cartridge selection depends on the specific contaminant, its airborne concentration, the exposure level, the oxygen level in the atmosphere, and applicable OSHA and NIOSH requirements. This guide is for research and does not replace a workplace hazard assessment or your written respiratory protection program. Never use air-purifying respirators in oxygen-deficient or IDLH atmospheres.
