North N75001L vs 7581P100L: OV vs OV/P100 (2026 Guide)
One Filters Vapor. The Other Filters Vapor and Dust.
Reviewed by the WC Safety Editorial Team — Last updated: June 2026.
Short answer: The difference between the North N75001L and 7581P100L is particulate protection. The Honeywell North N75001L (vendor: Honeywell North, SKU N75001L) is an organic vapor (OV) cartridge only — it stops solvent vapors but nothing solid. The North 7581P100L (vendor: Honeywell North, SKU 7581P100L) is an OV/P100 combination — the same organic vapor protection plus a P100 filter for dust, mist and fumes. So whether you search "North N75001L vs 7581P100L" or "7581P100L vs N75001L," the real question is: does your job also create particulate? If you spray paint or sand, the answer is yes — and you want the 7581P100L. If your only hazard is vapor, the N75001L is lighter and cheaper.
| Feature | N75001L | 7581P100L |
|---|---|---|
| Type | Organic vapor | OV + P100 |
| Organic vapor | Yes | Yes |
| Particulate (P100) | No | Yes |
| Spray paint | No | Yes |
| Cost | Lower | Higher |
Safety-critical point: a bare N75001L is not appropriate for spray painting. Sprayed paint is an aerosol — a particulate mist — and the N75001L has no particulate filter. Either add a North particulate prefilter over it, or far more simply use the 7581P100L OV/P100. Browse the full lineup in Honeywell North respirator cartridges.

What Is the Difference Between the North N75001L and 7581P100L?
Both cartridges deliver the same NIOSH-approved organic vapor protection and both clip onto a North facepiece with the same North bayonet connection. The 7581P100L adds one thing: a P100 particulate filter, capturing at least 99.97% of oil and non-oil particulates. That single addition separates an organic vapor cartridge from an OV/P100 combination — and it is the entire N75001L vs 7581P100L decision.
Think in terms of what is in the air. Pure solvent work — wiping with a degreaser, handling adhesives with ventilation — releases vapor, and the N75001L (read the N75001L review) handles vapor. The moment a process throws off something solid or liquid you can inhale — paint mist, sanding dust, pesticide dust — you also need particulate protection, and that is the 7581P100L (see the 7581P100L review). For the full North range, see all North respirator filters and cartridges.
North N75001L vs 7581P100L: Protection by Hazard
The fastest way to read the N75001L vs 7581P100L decision is to map it to the hazard you face. A check means the cartridge protects against that hazard as supplied; a cross means it does not on its own:
| Hazard | N75001L | 7581P100L |
|---|---|---|
| Solvent / paint fumes (vapor) | ✓ | ✓ |
| Spray paint mist | ✗ | ✓ |
| Sanding / general dust | ✗ | ✓ |
| Pesticide dust + vapor | Vapor only | ✓ |
| Mixed vapor + particulate | ✗ | ✓ |
| Particulate (P100) | ✗ | ✓ |
The pattern is consistent: anything that is purely vapor, both cover; anything that adds a particulate (mist, dust or fume), only the 7581P100L covers.
Which North Cartridge Is Better for Painting?
The 7581P100L, without question. Spray painting releases solvent vapor and atomized paint — and that paint mist is particulate. You need organic vapor and particulate protection at the same time, which is exactly what an OV/P100 cartridge provides. A bare N75001L filters the vapor but lets the mist through, so it is not suitable for spraying on its own. Run the 7581P100L on a comfortable North half mask from the 5500 series or 7700 series, or a North 54001 full facepiece for overhead spraying.
Where the N75001L and 7581P100L Sit in the North Lineup
Honeywell North cartridges step up by hazard. Knowing the family makes the choice — and the alternatives — obvious:
| Cartridge | Protects against |
|---|---|
| N75001L | Organic vapor only |
| N75002L | Acid gas only |
| N75003L | Organic vapor + acid gas |
| 7581P100L | Organic vapor + P100 particulate |
| 7583P100L | OV + acid gas + P100 |
| 75SCP100L | Multi-contaminant + P100 |
| 7580P100 / 75FFP100 | P100 particulate only |
For a particulate-only job, a standalone 7580P100 filter is the cheaper route; if you face acid gases alongside organic vapor, look at the 7583P100L or the multi-contaminant 75SCP100L.
Compatible Respirators & Service Life
Both cartridges use the Honeywell North bayonet connection and are interchangeable on North hardware: North half masks (5500 and 7700 series) and North full facepieces (5400, 7600 and the 54001). They are not compatible with 3M respirators, which use a different connection. Deciding between North half-mask platforms? See North 5500 vs 7700 series.
On service life: organic vapor cartridges do not last indefinitely. They must be swapped on a documented change schedule before vapor breakthrough — by the time you smell solvent, the cartridge is already spent. OSHA requires a change schedule for gas and vapor cartridges, since basic OV cartridges have no end-of-service-life indicator. The 7581P100L's P100 element is additionally replaced when breathing gets harder.
North N75001L or 7581P100L: Which Should You Buy?
Because the 7581P100L includes everything the N75001L does plus P100, the decision is simply "is there particulate in my air?"
Buy the North N75001L if…
- Your hazard is organic vapor only (no mist/dust)
- Degreasing, solvent wiping, adhesives with ventilation
- You want the lightest, lowest-cost OV cartridge
- You add a prefilter when particulate appears
Buy the North 7581P100L if…
- You spray paint or apply coatings
- You sand, or face pesticide dust
- Your job mixes solvents with dust or mist
- You want one cartridge for vapor + particulate
| If you are… | Better choice |
|---|---|
| Spray painting / coatings | North 7581P100L |
| Sanding + solvent work | North 7581P100L |
| Solvent wiping / degreasing (vapor only) | North N75001L |
| Lowest cost, vapor-only tasks | North N75001L |
| Particulate only (no vapor) | Use a 7580P100 filter |
Verdict: When in doubt and any particulate is involved, the 7581P100L is the safe default; reserve the N75001L for genuinely vapor-only work where its lower cost and weight win.

Frequently Asked Questions
What is the difference between the North N75001L and 7581P100L?
The Honeywell North N75001L is an organic vapor (OV) cartridge only — it stops solvent vapors but has no particulate filter. The 7581P100L is an OV/P100 combination cartridge: the same organic vapor protection plus a P100 filter that captures at least 99.97% of dusts, mists and fumes. If your work produces both vapor and particulate (such as spray paint), the 7581P100L is the complete solution.
Is the North 7581P100L better than the N75001L?
It is more capable, not simply better. The 7581P100L does everything the N75001L does plus P100 particulate filtration. If you face vapor only, the N75001L is lighter and cheaper and is the right tool. If you face vapor and particulate, the 7581P100L is the correct choice because the N75001L would leave you unprotected from the mist or dust.
Can the North 7581P100L replace the N75001L?
Yes. The 7581P100L provides the same organic vapor protection as the N75001L plus P100, so it covers every N75001L use case and more. Many shops standardize on the 7581P100L for versatility; others keep N75001L cartridges for pure-vapor tasks to save cost.
Should I buy the North N75001L or 7581P100L?
Choose the N75001L if your hazard is organic vapor only — solvents, adhesives, coatings with good ventilation. Choose the 7581P100L if there is also particulate, such as spray-paint mist, sanding dust or pesticide dust, because it combines vapor and P100 protection in one cartridge.
What does the North N75001L protect against?
The N75001L is NIOSH-approved for organic vapors — solvent vapors from paints, adhesives, coatings and cleaners. It has no particulate filter, so it does not protect against dust, mist or fume on its own.
What does the North 7581P100L protect against?
The 7581P100L protects against organic vapors plus particulates at the P100 level (at least 99.97% of oil and non-oil particles). That makes it suitable for jobs that combine solvent vapor with mist or dust, such as spray painting.
Does the North N75001L filter particles or dust?
No. The N75001L is organic vapor only with no particulate rating. To protect against dust or mist with an N75001L you must add a North particulate prefilter, or use the 7581P100L, which has P100 built in.
Does the North 7581P100L filter dust?
Yes. The 7581P100L includes a P100 filter, so it captures at least 99.97% of dusts, mists and fumes in addition to organic vapor protection.
Do I need a P100 filter with organic vapor protection?
Only if your task also produces particulate. Spraying creates mist, and sanding creates dust — both are particulate, so you need P100 (the 7581P100L). If the hazard is purely vapor with no mist or dust, an organic vapor cartridge like the N75001L is sufficient.
Which North cartridge is better for spray painting?
The 7581P100L. Spray paint releases solvent vapor and paint mist, and that mist is particulate. The OV/P100 7581P100L handles both in one cartridge. A bare N75001L filters the vapor but not the mist, so it is not appropriate for spray painting unless you add a particulate prefilter.
Which North cartridge is better for solvents?
For solvent vapor with no mist or dust — wiping, degreasing, adhesives in a ventilated area — the N75001L is the right, economical choice. The 7581P100L also works but adds P100 capability you may not need for pure-vapor solvent work.
Can the North N75001L be used for spray mist?
Not on its own — spray mist is particulate and the N75001L has no particulate filter. Either add a North particulate prefilter over it, or use the 7581P100L OV/P100 cartridge, which builds the particulate protection in.
Is the North 7581P100L worth the extra cost?
If there is any particulate in your work, yes — it combines two filters in one and removes the need for a separate prefilter. If your exposure is vapor only, the N75001L is the better value.
Are the North N75001L and 7581P100L NIOSH approved and interchangeable?
Both are NIOSH-approved Honeywell North bayonet cartridges and mount on the same North respirators, so they are physically interchangeable. They are not equivalent in protection — only the 7581P100L adds P100, so do not substitute an N75001L where particulate protection is required.
What respirators are the N75001L and 7581P100L compatible with?
Both use the Honeywell North bayonet connection and fit North half masks (5500 and 7700 series) and North full facepieces (5400, 7600 and 54001 series). They are not compatible with 3M respirators, which use a different connection.
How long do the North N75001L and 7581P100L last?
Organic vapor cartridges have a limited service life and must be replaced on a documented change schedule before vapor breakthrough — relying on smell or taste is unsafe. The 7581P100L's P100 element is additionally replaced when breathing becomes difficult. OSHA requires a change schedule for gas and vapor cartridges; follow your facility's respiratory protection program.
