Honeywell North 75FFP100 P100 Respirator Filter

Honeywell North 75FFP100 Overview

The Honeywell North 75FFP100 is a NIOSH-approved P100 particulate filter that captures ≥99.97% of oil and non-oil airborne particles — including dust, mist, fume, and aerosols — and mounts on North bayonet respirators via the universal North bayonet connection. It is sold as a single filter unit and delivers the highest NIOSH particulate efficiency rating available for half-mask and full-face air-purifying respirators. The 75FFP100 is the standalone particulate filter in the North 75xx/755x filter family — it provides no gas or vapor protection and is not a combination cartridge.

This filter is the right choice when your hazard assessment identifies airborne particulate as the sole inhalation risk and your respirator is a North 5500, 7700, 5400, or 7600 series mask. To understand how to match protection class to hazard, read the Honeywell North cartridge and filter guide, the respirator filter types explained guide, and the P100 vs N95 — which do you need guide, or browse the full Honeywell North respirator filters and cartridges collection.

Where the 75FFP100 Fits in Respirator Selection

Before ordering, confirm two things: that your respirator is a North 5500, 7700, 5400, or 7600 series mask (not a 3M, Moldex, or other brand), and that your hazard is particulate with no gas or vapor component requiring chemical cartridge protection.

• North respirator + particulate only → the 75FFP100 is the correct filter.
• North respirator + OV + P100 particulate → the 7581P100L OV/P100 combination cartridge.
• North respirator + acid gas + P100 particulate → the 7582P100L acid gas/P100 cartridge.
• North respirator + OV + acid gas + P100 → the 7583P100L OV/acid gas/P100 cartridge.
• North respirator + P100 particulate (2-pack preferred) → the 7580P100 (2-pack cartridge) is an alternative hard-body P100 option.
• Not sure whether you need P100 or a different class? The P100 vs N95 guide and how to choose a respirator cartridge guide walk through the decision step by step.

Who Should Buy the Honeywell North 75FFP100?

Buy the 75FFP100 if you run a North 5500, 7700, 5400, or 7600 series respirator and your workplace hazard assessment identifies airborne particulate — silica dust, lead dust, asbestos, coal dust, wood dust, welding fume, or other NIOSH-defined non-vapor aerosols — as the inhalation risk, with no co-occurring gas or vapor hazard requiring chemical sorbent protection.

Choose a different cartridge if:

• Organic vapors (solvents, coatings, fuels) are also present → the 7581P100L (OV + P100) adds OV protection to the same P100 efficiency.
• Acid gases accompany the particulate hazard → the 7582P100L (acid gas + P100).
• Both OV and acid gas are co-hazards → the 7583P100L (OV + acid gas + P100).
• Ammonia or methylamine is a co-hazard → the 7584P100L (ammonia/methylamine + P100).
• You run a 3M, Moldex, or any non-North respirator → the 75FFP100 uses the North bayonet connection and will not seat on any other brand's facepiece.
• Only particulate protection is needed and a lower efficiency class is acceptable → consider the 7506N95 prefilter or 7506R95 prefilter for lower-hazard applications.

What Does the 75FFP100 Protect Against?

What the 75FFP100 Does NOT Protect Against

• Organic vapors
• Acid gases
• Ammonia / methylamine
• Formaldehyde
• Mercury vapor
• Chlorine gas
• Carbon monoxide
• Hydrogen sulfide
• Oxygen deficiency
• IDLH atmospheres
• Unknown atmospheres
• Any gas or vapor hazard

Safety: The 75FFP100 is a P100 particulate filter only and provides zero protection against gases or vapors of any kind. It fits only North bayonet respirators — it cannot be forced onto 3M, Moldex, or any other brand's facepiece. Oxygen-deficient, unknown, and IDLH atmospheres require supplied air, SCBA, or another solution specified by a qualified safety professional. When gas or vapor co-hazards are also present, use the appropriate combination cartridge such as the 7581P100L (OV + P100) or another hazard-matched cartridge from the Honeywell North filters and cartridges collection.

Best Applications for the Honeywell North 75FFP100

Silica Dust Exposure (Construction, Masonry, Mining)

The 75FFP100's P100 rating — capturing ≥99.97% of oil and non-oil aerosols — is the appropriate particulate class for respirable crystalline silica, which OSHA's silica standard (29 CFR 1926.1153) requires to be controlled to 50 μg/m³ PEL. On a properly fitted North 5500 or 7700 half-face respirator, this filter delivers the assigned protection factor needed for most silica-generating construction tasks. Review the best respirator for silica dust 2026 guide for a full fit-factor and program discussion, and see all options in the Honeywell North respirator filters and cartridges collection.

Welding and Metal Fume Operations

Welding generates metal particulate fume — iron oxide, manganese oxide, and others — within the P100's capture range. The 75FFP100 handles the particulate component of welding fume on a North platform respirator; where welding gases (ozone, NOx) are also a concern in confined spaces or poorly ventilated areas, consult a qualified industrial hygienist before relying on a particulate-only filter. The best respirator for welding fumes guide covers the full selection decision.

Lead Abatement and Asbestos Work

OSHA lead (29 CFR 1910.1025) and asbestos (29 CFR 1910.1001) standards specify minimum APF requirements that a half-face respirator with a P100 filter can meet for many exposure scenarios — confirm your specific APF requirement with a safety professional. The 75FFP100 provides the highest-efficiency NIOSH particulate class on the North bayonet platform for these regulated abatement applications.

General Dusty Environments (Woodworking, Mining, Agriculture)

Wood dust, grain dust, coal dust, and other non-oil-aerosol environments where no chemical vapor hazard exists are within the 75FFP100's intended use. For the best Honeywell North filter or cartridge for your specific application, use the buying guide to confirm the right protection class before ordering.

Honeywell North 75FFP100 Pros & Cons

Compatible Honeywell North Respirators

The 75FFP100 uses the universal North bayonet connection and fits all North series respirators in the 5500, 7700, 5400, and 7600 families. It is incompatible with 3M bayonet respirators, Moldex bayonet respirators, 3M Secure Click respirators, or any other non-North platform — the connections are not interchangeable.

75FFP100 vs Other Honeywell North Particulate Filters and Cartridges

75FFP100 vs 7580P100

Both the 75FFP100 and the 7580P100 deliver NIOSH P100 particulate protection on North bayonet respirators with no gas or vapor protection. The key differences are pack configuration and body style: the 75FFP100 is sold as a single filter unit, while the 7580P100 is a hard-body cartridge sold as a 2-pack. If you need to outfit both sides of a dual-cartridge North mask and prefer the hard-body cartridge form factor, the 7580P100 is the practical choice. The 75FFP100 makes more sense when buying individual replacements or when one filter needs replacement independently.

75FFP100 vs 7581P100L

This is the most important purchase decision for North-platform users working in environments where both particulate and organic vapor are present. The 75FFP100 covers particulate only; the 7581P100L adds an activated carbon OV layer to the same P100 particulate efficiency — making it the correct choice for spray painting, solvent cleaning, coating application, or any task where solvent vapors accompany airborne particles. If your hazard assessment confirms particulate with no vapor component, the 75FFP100 is the simpler and lower-cost option. Consult the organic vapor vs P100 guide for the decision framework.

75FFP100 vs 7506N95 Prefilter

The 7506N95 is a prefilter pad rated N95 (≥95% non-oil aerosols), designed to sit over a North gas cartridge as a combination filter layer — it is not a standalone particulate filter body in the same sense as the 75FFP100. The 75FFP100 provides P100 efficiency (≥99.97%) and is oil-proof (P-class), making it the stronger choice for oil-aerosol environments and regulated hazards (silica, lead, asbestos) that require the higher efficiency class. Use the 7506N95 when mounting a prefilter on a cartridge for light-duty non-oil particulate, and the 75FFP100 when P100 efficiency is required by your hazard assessment or regulatory standard. See all prefilter options including the 7506R95 and 7506N99 in the Honeywell North filters and cartridges collection.

What is the Honeywell North 75FFP100?

The Honeywell North 75FFP100 is a NIOSH-approved P100 particulate filter that captures ≥99.97% of oil and non-oil airborne aerosols — including dust, mist, and fume — on North bayonet respirators. It is a particulate-only filter with no gas or vapor protection, sold as a single filter unit. It uses the universal North bayonet connection compatible with North 5500, 7700, 5400, and 7600 series respirators.

What respirators does the 75FFP100 fit?

The 75FFP100 fits all Honeywell North respirators that use the universal North bayonet connection: the North 5500 Series half-face, North 7700 Series half-face, North 5400 Series full-face, and North 7600 Series full-face. It does not fit 3M bayonet respirators, 3M Secure Click respirators, Moldex respirators, or any other non-North platform.

Does the 75FFP100 protect against organic vapors or gases?

No. The 75FFP100 is a P100 particulate filter only and contains no activated carbon or chemical sorbent. It provides zero protection against organic vapors, acid gases, ammonia, mercury vapor, or any other gas or vapor hazard. When vapors are also present, the 7581P100L (OV + P100) or another combination cartridge is required.

How many filters come in a 75FFP100 package?

The 75FFP100 is sold as a single individual filter — one unit. A full-face or half-face dual-cartridge North respirator requires two filters (one per side), so order accordingly. The 7580P100 is available as a 2-pack if you prefer to buy both filters in one order.

Is the 75FFP100 approved for silica dust?

Yes. The NIOSH P100 class (≥99.97% efficiency for oil and non-oil aerosols) is the appropriate protection class for respirable crystalline silica on an air-purifying respirator. The 75FFP100 meets the particulate efficiency requirement for silica applications when used on a properly fitted North platform respirator within a written respiratory protection program per OSHA 1910.134.

Can the 75FFP100 be used for welding fumes?

Yes for the metal particulate fume component of welding — the P100 class captures metal oxide fumes at ≥99.97% efficiency. For welding in confined or poorly ventilated spaces where gaseous co-hazards (ozone, NOx) may also be present, consult a qualified industrial hygienist to determine whether a combination cartridge is also required.

Is the 75FFP100 oil-proof?

Yes. The P-class designation (P100) means this filter is tested with oil aerosols and is rated for use in environments containing oil mist or oil aerosols, in addition to non-oil particulate. This distinguishes it from N-class filters (such as N95 or N99), which are not rated for oil aerosol environments.

Honeywell North 75FFP100 Frequently Asked Questions

What does the Honeywell North 75FFP100 filter protect against?

The 75FFP100 protects against airborne particulate — dust, mist, fume, and oil and non-oil aerosols — at ≥99.97% efficiency under the NIOSH P100 rating. It provides no protection against gases, vapors, or chemical hazards of any kind. It is the correct filter when particulate is the sole inhalation hazard and your respirator is a North bayonet platform mask.

What North respirators is the 75FFP100 compatible with?

The 75FFP100 is compatible with all Honeywell North respirators using the universal North bayonet connection: the North 5500 Series half-face, North 7700 Series half-face, North 5400 Series full-face, and North 7600 Series full-face. It does not fit 3M, Moldex, GVS, or any other brand's respirator.

Will the 75FFP100 fit a 3M respirator?

No. The 75FFP100 uses the North bayonet connection, which is a different system from 3M's standard bayonet and 3M's Secure Click half-turn bayonet. North filters and 3M cartridges are not cross-compatible. Do not attempt to force-fit them — use filters and cartridges matched to your respirator's brand and connection system.

How many 75FFP100 filters do I need for my respirator?

A half-face or full-face dual-cartridge North respirator requires one filter per side — two total. The 75FFP100 is sold as a single individual filter, so order two for a complete set. Alternatively, the 7580P100 is available as a 2-pack if you prefer to order both at once.

Is the 75FFP100 good for silica dust and OSHA-regulated applications?

Yes. The P100 efficiency class (≥99.97% for oil and non-oil aerosols) is the appropriate NIOSH particulate rating for respirable crystalline silica work under OSHA 29 CFR 1926.1153. Use it on a properly fitted North respirator within a written respiratory protection program. Confirm assigned protection factor requirements with your safety professional for your specific exposure scenario.

Does the 75FFP100 have an end-of-service-life indicator?

P100 particulate filters do not have a chemical sorbent to saturate, so there is no ESLI for gas/vapor breakthrough. Replace the filter when breathing resistance increases significantly (indicating filter loading), when it is physically damaged, torn, or contaminated, or per your employer's written change-out schedule under OSHA 1910.134.

Can I use the 75FFP100 for spray painting?

Only if the hazard is paint mist or aerosol particulate with no solvent vapor present — which is rarely the case in real spray painting. Most spray painting operations produce both atomized particulate and organic vapor, requiring a combination cartridge. For spray painting, the 7581P100L (OV + P100) is the correct selection for most North-platform users.

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

Both are NIOSH P100 particulate-only filters for North bayonet respirators with no gas or vapor protection. The 75FFP100 is sold as a single individual filter; the 7580P100 is a hard-body cartridge sold as a 2-pack. The choice comes down to pack quantity preference and form factor — the function is the same P100 particulate filtration.

What is the difference between the 75FFP100 and the 7581P100L?

The 75FFP100 is particulate (P100) only. The 7581P100L adds an organic vapor layer — making it a combination OV/P100 cartridge for environments where both solvents and particulate are present. If organic vapors are part of your hazard profile, the 7581P100L is the correct upgrade from the 75FFP100.

Is the 75FFP100 rated for oil-mist environments?

Yes. The P (oil-proof) designation in P100 means this filter is tested and rated for use with oil-based aerosols and mist, in addition to non-oil particulate. This makes it suitable for metalworking, machining, and other industrial environments involving cutting fluids or oil mist, where N-class filters would not be appropriate.

Can I use the 75FFP100 for lead dust or asbestos abatement?

Yes, the P100 efficiency class is specified for lead and asbestos applications in OSHA's respective standards (29 CFR 1910.1025 for lead, 29 CFR 1910.1001 for asbestos) when used on an appropriately rated APF respirator within a compliant respiratory protection program. Confirm your specific APF requirement and fit-testing status with a qualified safety professional.

How do I know when to replace the 75FFP100?

Replace the 75FFP100 when breathing resistance increases noticeably during use (indicating particle loading), when the filter is physically damaged, torn, or heavily soiled, or when it has been contaminated by hazardous material. Since it is a particulate-only filter with no chemical sorbent, there is no odor or taste breakthrough indicator — replacement is condition-based or per a written schedule.

Does the 75FFP100 work with the Honeywell North 7700 half-face respirator?

Yes. The North 7700 Series half-face respirator uses the universal North bayonet connection, and the 75FFP100 is fully compatible with it. Ensure the filter is seated correctly and that the facepiece achieves a proper seal per your respiratory protection program's user seal check procedure.
