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

Honeywell North 7580P100 Overview

The Honeywell North 7580P100 is a NIOSH-approved P100 particulate filter that captures ≥99.97% of oil and non-oil airborne particles — including fine silica dust, welding fume, lead dust, asbestos fibers, mists, and aerosols — and is sold as a 2-pack (one pair). It uses the Honeywell North bayonet mount and attaches directly to North 5500, 7700, 5400, and 7600 series half-face and full-face respirators. The 7580P100 is a particulate filter only — it provides no protection against gases or vapors of any kind. Buy it when your hazard assessment identifies airborne particles as the primary risk and your respirator is a Honeywell North platform mask.

When organic vapors or solvents accompany the particulate hazard, the correct upgrade is the 7581P100L OV/P100 combination cartridge; for acid gas plus particulate, choose the 7582P100L acid gas/P100 cartridge. To understand the full North cartridge family and how to match protection class to hazard, read the Honeywell North cartridge guide, the P100 vs N95 guide, or browse the full Honeywell North respirator filters and cartridges collection.

Where the 7580P100 Fits in Respirator Selection

Before ordering, confirm two things: your respirator is a Honeywell North bayonet-mount mask (5500, 7700, 5400, or 7600 series), and your hazard is particulate only — no gases or vapors that require activated-carbon cartridge protection.

• North bayonet mask + particulate only → the 7580P100 is the correct filter.
• North bayonet mask + particulate + organic vapor → the 7581P100L OV/P100 combination cartridge.
• North bayonet mask + particulate + acid gas → the 7582P100L acid gas/P100 cartridge.
• North bayonet mask + particulate + OV + acid gas → the 7583P100L OV/AG/P100 cartridge.
• North bayonet mask + particulate + ammonia → the 7584P100L ammonia/methylamine/P100 cartridge.
• Unsure of your hazard class? The how to choose a respirator cartridge guide and respirator filter types explained walk through the decision step by step.
• You run a 3M or Moldex respirator → the 7580P100 will not fit; bayonet connection systems are brand-specific and not interchangeable.

Who Should Buy the Honeywell North 7580P100?

Buy the 7580P100 if you run a Honeywell North 5500, 7700, 5400, or 7600 series respirator and your workplace hazard assessment identifies airborne particulate — fine dust, mist, fume, or aerosol — as the sole respiratory risk with no significant gas or vapor co-hazard.

Choose a different filter or cartridge if:

• Organic vapors or solvents are also present → the 7581P100L OV/P100 combination cartridge handles both.
• Acid gases (chlorine, HCl, SO₂) are a co-hazard → the 7582P100L acid gas/P100 cartridge.
• OV and acid gas are both present with particulate → the 7583P100L OV/AG/P100 cartridge.
• Ammonia or methylamine is present → the 7584P100L ammonia/methylamine/P100 cartridge.
• You need a lower protection class for nuisance dust with no oil mist → see the prefilter options: 7506N95 or 7506R95.
• Your respirator is a different brand → North filters are not cross-compatible with 3M, Moldex, or other bayonet systems.

What Does the 7580P100 Protect Against?

What the 7580P100 Does NOT Protect Against

• Organic vapors and solvents
• Acid gases
• Ammonia / methylamine
• Mercury vapor
• Formaldehyde
• Carbon monoxide
• Hydrogen fluoride
• Multi-gas hazards
• Oxygen deficiency
• IDLH atmospheres
• Unknown atmospheres
• Any gas or vapor hazard

Safety: The 7580P100 is a P100 particulate filter only — it provides no gas, vapor, or oxygen protection. It fits only the Honeywell North bayonet platform and cannot be fitted to 3M, Moldex, or any other brand of respirator. Oxygen-deficient, unknown, and IDLH atmospheres require supplied-air equipment, SCBA, or another solution specified by a qualified safety professional. When gases or vapors accompany the particulate hazard, a combination cartridge such as the 7581P100L OV/P100 is required.

Best Applications for the 7580P100

Silica Dust Control — Construction, Masonry, and Mining

Respirable crystalline silica is one of the most regulated occupational particulate hazards in North America, and NIOSH-approved P100 protection is the standard recommendation for grinding, cutting, drilling, or sweeping silica-containing materials. The 7580P100's ≥99.97% filtration efficiency makes it the appropriate filter for silica-generating tasks on North-platform programs. For a full selection guide, read the best respirator for silica dust guide.

Welding and Metal Cutting Fume

Metal welding generates iron oxide, manganese, zinc oxide, and other metal fume particles in the respirable range. P100 filters like the 7580P100 capture these ultra-fine metallic particles at ≥99.97% efficiency and are rated for oil-based aerosols, making them suitable across a broad range of welding processes. When welding coatings or treated metals also produce organic vapor, upgrade to the 7581P100L combination cartridge. See the best respirator for welding fumes guide for setup recommendations.

Lead Abatement and Paint Disturbance

OSHA's lead standard (29 CFR 1910.1025 / 1926.62) requires P100 or higher for workers performing lead abatement, sanding, or disturbing lead-based paint. The 7580P100 meets this class requirement on North-platform half-face and full-face respirators. Confirm that your program's respiratory protection plan specifies the correct facepiece and fit-test schedule in addition to filter selection.

General Industrial Dust and Oil Mist

Machining operations, grinding, buffing, and other industrial processes that generate fine dust and oil aerosols benefit from P-series filter protection. The 7580P100 is oil-proof (P-class) rather than oil-resistant (R-class) or oil-intolerant (N-class), making it the appropriate filter when oil aerosols are present in the work environment. Browse all North particulate options in the Honeywell North filters and cartridges collection.

Honeywell North 7580P100 Pros & Cons

Compatible Honeywell North Respirators

The 7580P100 uses the Honeywell North bayonet mount — the universal connection shared by all North 75xx and N750xx series filters and cartridges. It fits only Honeywell North bayonet respirators. It will not fit 3M bayonet respirators, 3M Secure Click respirators, Moldex respirators, or any other brand.

The Honeywell North bayonet is a brand-specific connection — North cartridges and filters are not interchangeable with 3M, Moldex, or any other manufacturer's respirator system. The 7580P100 attaches to North facepieces using the same universal North bayonet connection shared by all 75xx and N750xx series filters and cartridges in this line. For a broader view of available North protection options, visit the Honeywell North respirator filters and cartridges collection.

7580P100 vs Other Honeywell North P100 Filters and Cartridges

7580P100 vs 75FFP100

Both are NIOSH P100 particulate-only filters for the Honeywell North bayonet platform with no gas protection. The 75FFP100 is an alternate filter format in the same North 75xx line — if your program already specifies one or the other, match what your facepiece manufacturer recommends. Both provide identical P100 filtration class; the difference is in physical housing format and how they seat on specific North facepieces. Confirm compatibility with your specific mask model before switching formats.

7580P100 vs 7581P100L

This is the most common North P100 purchase decision for users in painting, coating, and industrial solvent environments. The 7580P100 is a particulate-only filter; the 7581P100L is a combination cartridge that adds organic vapor protection to the same P100 particulate layer. When your hazard assessment confirms only airborne particles with no solvents or vapors — dry grinding, sawing, or dusty cleanup — the 7580P100 is the lower-cost, simpler answer. When spray painting, working with coatings, or in any environment where solvent vapors are present alongside particulate, the 7581P100L is the correct selection. Consult the organic vapor vs P100 guide for the full decision logic.

7580P100 vs 7506N95

The 7506N95 is an N95-class prefilter — oil-intolerant, 95% efficient — designed for nuisance dust in environments with no oil mist. The 7580P100 is a full P100 filter — oil-proof, 99.97% efficient — appropriate for hazardous particulate (silica, lead, asbestos, metal fume) and any environment with oil aerosols. When the hazard is truly low-level nuisance dust and no oil is present, the 7506N95 is a lower-cost option. When the hazard is regulated or involves oil mist, the 7580P100 is the correct class. Read the P100 vs N95 difference guide for the full comparison.

Honeywell North 7580P100 Quick Answers

What is the Honeywell North 7580P100?

The Honeywell North 7580P100 is a NIOSH-approved P100 particulate filter that captures ≥99.97% of airborne particles, including both oil and non-oil aerosols. It is sold as a 2-pack (one pair) and uses the Honeywell North bayonet mount on North 5500, 7700, 5400, and 7600 series respirators. It provides no protection against gases or vapors of any kind.

What respirators does the 7580P100 fit?

The 7580P100 fits Honeywell North 5500 series (half-face), 7700 series (half-face), 5400 series (full-face), and 7600 series (full-face) respirators via the North bayonet connection. It is mechanically incompatible with 3M bayonet respirators, 3M Secure Click respirators, Moldex respirators, and any other brand.

Does the 7580P100 protect against gases or vapors?

No. The 7580P100 is a P100 particulate filter only. It contains no activated-carbon or chemical sorbent media and provides zero protection against organic vapors, acid gases, ammonia, mercury vapor, or any other gas-phase hazard.

Honeywell North 7580P100 Frequently Asked Questions

What is the Honeywell North 7580P100 used for?

The 7580P100 is used to provide P100 particulate protection against dust, mist, fume, and oil-based aerosols on Honeywell North 5500, 7700, 5400, and 7600 series respirators. Common applications include silica dust control, welding fume, lead abatement, asbestos work, and general industrial dust environments where no gas or vapor co-hazard is present.

Does the 7580P100 fit 3M respirators?

No. The 7580P100 uses the Honeywell North bayonet connection, which is not compatible with any 3M respirator — neither 3M standard bayonet masks nor 3M Secure Click masks. North and 3M bayonet systems are brand-specific and not interchangeable.

Is the 7580P100 rated for oil-based aerosols?

Yes. The "P" in P100 stands for oil-proof, meaning the filter maintains its ≥99.97% efficiency rating even when exposed to oil-based aerosols. This makes the 7580P100 suitable for machining, grinding, and industrial processes where oil mist is present, unlike N-class (oil-intolerant) or R-class (oil-resistant, 8-hour limit) filters.

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

Both are NIOSH P100 particulate-only filters for the Honeywell North bayonet platform and provide identical filtration class — ≥99.97% efficiency, no gas protection. The difference is in physical housing format. Confirm which format your specific North facepiece model accepts before ordering, as housing geometry can vary between North series.

When should I upgrade from the 7580P100 to a combination cartridge?

Upgrade to a combination cartridge any time your hazard assessment identifies a gas or vapor co-hazard alongside particulate. Use the 7581P100L when organic vapors are present, the 7582P100L when acid gases are the co-hazard, the 7583P100L when both OV and acid gas are present, or the 7584P100L when ammonia is involved. The 7580P100 alone provides no chemical gas protection.

Can I use the 7580P100 for lead paint abatement?

A P100-class filter on a properly fit-tested respirator meets the filter requirement under OSHA's lead standards (29 CFR 1910.1025 and 1926.62) for disturbance and abatement tasks. Confirm that your full respiratory protection program — including the facepiece selection, fit testing, and program administration — satisfies the applicable OSHA standard for your work classification.

How often should I replace the 7580P100?

Replace the 7580P100 when breathing resistance increases to an uncomfortable level, when the filter is physically damaged, or when it becomes soiled. Particulate filters do not have a chemical breakthrough indicator — manage replacement on a schedule consistent with your written respiratory protection program under OSHA 1910.134. Filters used in high-dust environments may require more frequent replacement than those in light-duty applications.

Is the 7580P100 compatible with all Honeywell North bayonet cartridges?

All Honeywell North 75xx and N750xx series filters and cartridges share the universal North bayonet connection, so the facepiece that accepts the 7580P100 also accepts other North-line cartridges such as the 7581P100L, 7582P100L, 7583P100L, and gas-only N750xx series. This allows users to switch between protection classes by simply changing the cartridge or filter.

Does the 7580P100 work for asbestos?

P100-class filtration is the NIOSH-recommended minimum for Class I, II, and III asbestos work under OSHA 1926.1101. The 7580P100 on a properly fit-tested North half-face or full-face respirator provides P100 protection. Full compliance with the OSHA asbestos standard requires a complete written respiratory protection program, including medical evaluation, fit testing, and training — filter selection alone is not sufficient.

Does the 7580P100 protect against formaldehyde?

No. Formaldehyde is a gas-phase hazard and is not captured by a particulate filter. The 7580P100 provides no protection against formaldehyde or any other gas. A combination cartridge with formaldehyde-rated sorbent media is required; consult the respirator filter types guide to identify the correct North cartridge for formaldehyde co-hazards.

What is the difference between the 7580P100 and North prefilters (7506N95, 7506R95)?

The 7580P100 is a full-size P100 filter that replaces a cartridge position on the respirator and provides stand-alone P100 particulate protection. The North prefilters (7506N95, 7506R95, 7504R95) are thin disposable pads designed to extend the service life of gas cartridges by pre-capturing particulate before it clogs the cartridge sorbent bed — they are not standalone filters. Use the 7580P100 for dedicated P100 particulate-only protection; use prefilters over a gas cartridge when both gas and particulate hazards are present and you want to maximize cartridge life.

Is the 7580P100 good for silica grinding and cutting work?

P100 is the recommended protection class for tasks generating respirable crystalline silica — including concrete grinding, masonry cutting, and abrasive blasting. The 7580P100 on a properly fit-tested North respirator meets the P100 filter requirement for silica-exposure tasks. Refer to the best Honeywell North cartridge for silica dust guide for a full program recommendation.
