Honeywell North 75Ffp100 Review
WC Safety Editorial Verdict: 4.4/5
The Honeywell North 75FFP100 earns a strong editorial score as the most flexible way to keep North bayonet respirators in service: it delivers the identical NIOSH 99.97% P100 efficiency of the paired 7580P100, but in single-unit form so you can swap one damaged or clogged filter without scrapping a working partner. Because the protection is particulate-only, the decision between this filter and a combination cartridge comes down to your hazard — confirm yours with our how to choose a respirator cartridge guide before buying.
We score it editorially on spec compliance, fit-to-purpose, and program logistics rather than on customer ratings, which were not available for this SKU at the time of review.
Is the Honeywell North 75FFP100 the Right P100 Particulate Filter for Single-Side Replacement?
Published · Last updated
The Honeywell North 75FFP100 is a NIOSH-approved P100 particulate filter sold as an individual unit, giving safety managers the ability to replace a single damaged or clogged filter without discarding an entire pair. It provides identical 99.97% filtration efficiency to the paired 7580P100 — the choice is purely an inventory and logistics decision.
Editorial Verdict — 75FFP100: 4.4/5
The go-to single-unit P100 filter for North bayonet respirators. Same NIOSH 99.97% protection as the 7580P100 pair — choose this when you need to replace one filter independently or manage replacement inventory at the individual unit level.

P100 Filter Performance: What 99.97% Means in Practice
Under NIOSH 42 CFR Part 84, P100-rated filters must block at least 99.97% of airborne particles at 0.3 microns — the most penetrating particle size for electrostatic fiber filters. This efficiency rating applies to the hardest-to-capture particle size, meaning the 75FFP100 is even more efficient at capturing larger particles (asbestos fibers, lead dust, silica, mold spores) that are more readily intercepted by mechanical filtration.
The P-series designation also means the 75FFP100 is oil-proof — safe for use in oil aerosol environments (mist coolants, hydraulic fluid mist, metalworking fluids) without degradation of filter efficiency over time. This distinguishes it from N-series (not oil-resistant) and R-series (oil-resistant for one shift only) filters.
75FFP100 vs. 7580P100: Single vs. Pair
| Attribute | 75FFP100 vs. 7580P100 |
|---|---|
| Units per package | Single filter vs. Pair (2 filters) |
| NIOSH approval | Identical — same P100 rating |
| Filter efficiency | Identical — 99.97% |
| Best for | Single-unit replacement, spare inventory |
| 7580P100 best for | New installations, initial outfitting, bulk buying |
The 75FFP100 makes the most sense when: one filter in a pair is damaged but the other is still functional; your respiratory protection program tracks filters individually; or your stockroom prefers single-unit inventory over pairs.
Compatible Honeywell North Respirators
Compatible with all Honeywell North bayonet respirators including the North 5500 Series half-face, North 7600 and 5400 Series full-face respirators. Not compatible with 3M bayonet respirators — Honeywell North and 3M use different mounting systems.
Applications
- Asbestos abatement: P100 efficiency meets OSHA 1926.1101 HEPA-equivalent requirement
- Lead paint removal: NIOSH P100 required for RRP work per EPA 40 CFR Part 745
- Crystalline silica: P100 recommended for high-concentration silica operations per OSHA 1910.1053
- Metalworking / machining: protects against metal fumes and mist
- Mold remediation: P100 efficiency more than sufficient for mold spores (3-100 microns)
Filter Maintenance and Replacement
- Inspect before each use — look for holes, tears, cracks, or contamination of filter media
- Do not wash or attempt to clean filter media — electrostatic charge is compromised by moisture
- Replace when: visibly damaged, breathing resistance increases significantly, or filter is contaminated with oil or liquid
- P100 filters do not have a fixed time-based change schedule — replace on condition, not calendar
- Store unmounted, in original packaging or sealed bag, away from heat, UV, and chemical vapors

Frequently Asked Questions
Q: What does P100 mean on a respirator filter?
A: P100 is a NIOSH filter class under 42 CFR Part 84. It means the filter achieves at least 99.97% efficiency for airborne particles at 0.3 microns. The P designation means the filter is oil-proof — safe for use with oil aerosols without filter efficiency degradation. The 100 indicates the 99.97% efficiency level (compared to 95 for N95 or 99 for N99).
Q: Is the 75FFP100 the same as the 7580P100?
A: Yes in terms of filtration performance — both are NIOSH P100 filters rated at 99.97% efficiency. The difference is packaging: 75FFP100 is sold individually (one filter) while 7580P100 is sold in pairs. Both fit the same Honeywell North bayonet respirators.
Q: What respirators is the 75FFP100 compatible with?
A: The 75FFP100 fits all Honeywell North bayonet-mount respirators including the 5500 Series half-face respirators, 7600 Series full-face respirators, and 5400 Series full-face respirators. It is not compatible with 3M bayonet respirators.
Q: Can the 75FFP100 be used for asbestos work?
A: Yes — the P100 efficiency (99.97%) meets and exceeds the HEPA-equivalent requirement for asbestos abatement under OSHA 29 CFR 1926.1101. For Class I and II work above 1 f/cc, pair with a full-face North respirator for APF 50 protection.
Q: Does P100 filter organic vapors?
A: No — P100 is a particulate-only filter. It does not adsorb gases or vapors. For applications with both particulate and vapor hazards (spray painting, chemical spraying), use a combination OV/P100 cartridge such as the Honeywell North 7581P100L.
Q: How do I know when to replace a P100 filter?
A: Replace a P100 filter when: it is visibly damaged or contaminated, breathing resistance increases noticeably (may indicate filter loading), it has been wetted (moisture destroys the electrostatic charge), or your written change schedule requires replacement. There is no fixed number of hours or shifts for P100 filter replacement.
Q: Can I clean and reuse a P100 filter?
A: No — do not attempt to clean, wash, or blow out a P100 filter. Doing so destroys the electrostatic charge that enables high-efficiency particle capture and voids NIOSH approval. Replace contaminated or clogged filters.
Q: What is the difference between N100, R100, and P100 filters?
A: All three achieve 99.97% particle efficiency at 0.3 microns. The difference is oil resistance: N100 = not resistant to oil aerosols; R100 = oil-resistant for one work shift (8 hours); P100 = oil-proof, suitable for multi-shift use in oil aerosol environments. The 75FFP100 is P100, meaning it is safe for oil mist environments without time restriction per manufacturer guidelines.
Q: Does the 75FFP100 protect against wildfire smoke?
A: Yes — the P100 filter captures PM2.5 particles (including wildfire smoke particulate) at 99.97% efficiency, exceeding N95 (95%) protection. For outdoor wildfire smoke work, a P100 filter on a fitted Honeywell North half-face respirator provides superior protection compared to disposable N95 masks.
Q: What is the OSHA APF for a respirator using P100 filters?
A: The OSHA APF is determined by the respirator type, not the filter. A half-face respirator with P100 filters has APF 10; a full-face respirator with P100 filters has APF 50. The P100 efficiency means the filter is not the limiting factor — the facepiece seal determines the protection level.
Q: Are Honeywell North filters compatible with 3M respirators?
A: No. Honeywell North uses the North bayonet mount; 3M uses the 3M bayonet mount. These are different and incompatible. Using a North filter on a 3M respirator (or vice versa) is dangerous — it will not mount properly, creating an uncontrolled air bypass. Always match filter brand to respirator brand.
Q: Can the 75FFP100 be used with the Honeywell 5500 half-face series?
A: Yes — the 75FFP100 fits the Honeywell North 5500 Series half-face respirators. Pair with the appropriate cartridge adapter if using with combination protection, or mount directly to the bayonet for particulate-only protection.
Q: What is the shelf life of unused P100 filters?
A: Typically 5 years from manufacture date when stored in original sealed packaging. Store away from UV light, ozone, heat sources, and chemical vapors. Check the expiration date printed on the packaging before use.
Q: How does P100 compare to N95 for protection?
A: P100 at 99.97% efficiency is dramatically better than N95 at 95% — more than 166× fewer particles pass through. Additionally, P100 is oil-proof while N95 is not oil-resistant. For high-concentration particle hazards, P100 on a properly fitted reusable respirator provides substantially greater protection than a disposable N95.
Q: Where can I buy the Honeywell North 75FFP100?
A: The 75FFP100 is reviewed at WC Safety. Browse all Honeywell North cartridges and filters including P100 filters, OV cartridges, and combination cartridges.
OSHA Assigned Protection Factors: Respirator Type Determines Protection Level
A critical and frequently misunderstood principle: the protection factor (APF) is determined by the respirator type, not the cartridge. The cartridge determines which chemicals are protected against; the facepiece type determines how much protection is provided relative to the permissible exposure limit (PEL).
| Respirator Type | OSHA APF (29 CFR 1910.134 App A) |
|---|---|
| Half-face air-purifying (e.g., North 5500 Series) | APF 10 — protects up to 10× the PEL |
| Full-face air-purifying (e.g., North 7600/5400 Series) | APF 50 — protects up to 50× the PEL |
| Powered air-purifying (PAPR), half-face | APF 50 |
| Powered air-purifying (PAPR), full-face/hood | APF 1000 |
Example: if the OSHA PEL for a solvent is 100 ppm, a half-face respirator (APF 10) with the appropriate cartridge protects up to 1,000 ppm; a full-face (APF 50) protects up to 5,000 ppm. If your measured air concentration exceeds the APF × PEL product, you need a higher APF respirator or must implement engineering controls to reduce concentration.
Fit Testing: Why It Matters More Than Cartridge Choice
Even the most appropriate cartridge selection cannot compensate for a poorly fitting respirator. OSHA 1910.134 requires fit testing for all tight-fitting respirators (half-face and full-face) — annually at minimum, and whenever the worker changes respirator model, size, or if physical changes (weight loss/gain >10%, dental work, scarring) may affect facial fit.
- Qualitative fit test (QLFT): uses a challenge agent (isoamyl acetate, Bitrex, or saccharin) — pass/fail based on taste/smell detection; limited to APF 10 respirators
- Quantitative fit test (QNFT): uses an instrument to measure actual face seal leakage; required for APF 50+ respirators and more rigorous for half-face programs
- Honeywell North 5500 half-face respirators are available in S/M/L sizes — workers must be fit-tested to the correct size
- Full-face North 7600/5400 respirators must be sized for proper temple and chin seal contact
- Beards, sideburns, or facial hair that passes through the sealing surface will always fail fit testing — these workers require a PAPR or supplied-air option
Additional Frequently Asked Questions
Q: Can the 75FFP100 be used for lead abatement in residential renovation?
A: Yes — the NIOSH P100 efficiency meets and exceeds the requirement for lead work under OSHA 1926.62 (construction) and EPA RRP regulations (40 CFR Part 745). For lead paint work generating dust and debris, P100 is the appropriate filter class.
Q: Does the 75FFP100 require HEPA certification in addition to NIOSH P100?
A: No — NIOSH P100 at 99.97% efficiency is accepted as equivalent to HEPA (also 99.97%) for regulatory purposes in respiratory protection. HEPA is a designation used for vacuum filtration equipment; P100 is the NIOSH term for the same 99.97% efficiency in respirator filters.
Q: What is the difference between the 75FFP100 and the 75FFP100NL?
A: Some North P100 filters are sold in slightly different variants. The standard 75FFP100 is the NIOSH P100 individual filter. Verify the exact model number on packaging and cross-reference with NIOSH CEL for your specific compliance requirement. Always use filters within their labeled NIOSH TC approval.
Q: Is the 75FFP100 approved for use in asbestos operations above 1 f/cc?
A: NIOSH P100 provides 99.97% efficiency. However, OSHA 1926.1101 for Class I and II asbestos work at exposures above 1 f/cc requires full-face respirators (APF 50) or PAPRs. A P100 filter on a half-face respirator provides APF 10 protection — appropriate for exposures up to 1 f/cc. Above that, a full-face respirator with P100 is required.
Q: How do I dispose of used P100 filters contaminated with hazardous materials?
A: Disposal requirements depend on the contaminant. Filters used for lead, asbestos, or hazardous particulates may require disposal as hazardous waste under EPA and state regulations. Consult your industrial hygienist and local waste disposal requirements before discarding used filters from hazardous operations.

Pros & Cons
Pros
- Single-unit packaging lets you replace one filter independently instead of discarding a still-good pair, cutting waste in active respiratory programs
- Full NIOSH P100 99.97% efficiency at 0.3 microns under 42 CFR Part 84 - identical protection to the paired 7580P100
- P-series oil-proof rating makes it safe for oil-mist and metalworking-fluid environments where N-series filters are not permitted
- Mounts directly to all Honeywell North bayonet respirators (5500 half-face, 7600/5400 full-face) with no adapter for particulate-only work
- Condition-based replacement (not a fixed calendar) keeps cost-per-shift low for intermittent or dust-only tasks
Cons
- Particulate-only - provides no protection against organic vapor, acid gas, or ammonia, so it cannot stand in for a combination cartridge
- Buying singles can cost more per filter than the 7580P100 pair when you are outfitting a crew from scratch
- North bayonet mount is brand-locked - it will not fit 3M or Moldex facepieces, limiting cross-brand stockrooms
- No ESLI end-of-service indicator (none exists for particulate filters), so loading judgement rests on breathing resistance and inspection
Who It's For
Buy it if:
- Safety managers running an established Honeywell North program who need to replace a single filter without breaking a pair
- Crews working dust-only particulate hazards - silica, lead, asbestos, mold, metal fume - that need P100 but no vapor protection
- Stockrooms that track and issue respirator filters at the individual-unit level rather than by the pair
- Oil-mist and metalworking-fluid environments that specifically require a P-series oil-proof filter
Look elsewhere if:
- Workers facing organic vapor or acid gas hazards - they need a combination cartridge such as the 7581P100L (OV + P100) or 7583P100L (OV + acid gas + P100) instead; ammonia or methylamine work needs the 7584P100L, which neither of those two covers
- Anyone outfitting a new crew from scratch, where the 7580P100 paired pack is usually the lower cost-per-filter buy
- Owners of 3M or Moldex respirators - the North bayonet mount is not cross-compatible with those facepieces

Common questions
Does the rating on the box equal the protection I get?
No. Published ratings come from laboratory conditions. Regulators apply derating precisely because real fit is worse, and the derated figure is the one to plan from.
Which figure should a written program use?
The derated one, and the conservative derate where more than one applies. Planning on the label is how a worker ends up with less protection than the paperwork claims.
Who is responsible for providing this equipment?
Where a standard requires PPE for a hazard, the employer provides it at no cost to the employee, along with training in its use, care and limitations.
Does equipment expire?
Most of it does. Elastomers harden, foams stop rebounding, and coatings craze. A component past its service life can look perfectly serviceable and no longer perform.
Is a higher rating always better?
No. Over-protection carries its own hazards, from isolation from alarms to heat stress and reduced dexterity. Match the rating to the measured or assessed exposure.
What if two published sources disagree?
Treat it as unresolved and plan on the lower figure until the manufacturer or the marking on the item settles it. We flag these disagreements on the page rather than picking one.
Does a foreign approval count in the United States?
Generally no. US workplaces require the US approval - NIOSH for respirators, and the relevant ANSI standard for most other PPE. A CE, EN or AS/NZS mark describes a different test.
Is training required as well as equipment?
Where a standard requires PPE it almost always requires training with it: what the hazard is, how to fit and inspect the item, its limitations, and when to replace it.
Does PPE replace engineering controls?
No. PPE sits at the bottom of the hierarchy of controls. Where engineering or administrative controls can reduce the exposure, they are required first and PPE is not a substitute.
How do I know an item actually meets the standard it claims?
Look for the marking on the item itself, not the listing copy. Standards specify what must be stamped on the product, and a claim that appears only in a description is not a marking.
Do I need to keep records?
For most PPE-triggering standards, yes - hazard assessments, training, and where applicable monitoring or medical surveillance. The record is what demonstrates the program exists.
What should I check when equipment arrives?
That the markings match what was ordered, that nothing is damaged or past a stated shelf life, and that the size range actually covers the people who will wear it.
How often should this be reviewed?
Whenever the work changes, the equipment changes, or the standard is revised - and on a stated interval regardless, so the review happens even when nothing appears to have changed.
Where does the authoritative wording live?
In the regulation or consensus standard itself, not in a summary. Anything on this page is a reading of that text and the citation is given so it can be checked.
Does a higher price indicate better protection?
No. Protection is defined by the rating and the fit achieved, not the price. A correctly fitted inexpensive item outperforms a poorly fitted expensive one every time.
