Honeywell North 75SCP100L Overview

The Honeywell North 75SCP100L is a NIOSH-approved combination cartridge that snaps onto North bayonet half- and full-face respirators to protect against multi-gas AND airborne particulate in one unit. The built-in P100 filter captures at least 99.97% of particles, so the 75SCP100L covers gas plus dust, mist and fume without a separate prefilter. Start with our guide to choosing a respirator cartridge and the Honeywell North cartridge guide, then confirm the markings on the respirator cartridge color chart.

The 75SCP100L cartridge belongs to the Honeywell North respirator filters and cartridges family. Read our hands-on Honeywell North 75SCP100L review for field-tested detail. Buy it when you face multi-gas together with dust; choose the gas-only 75SCL if there is no particulate.

Where the 75SCP100L Fits in Cartridge Selection

Confirm the hazards before the cartridge. The 75SCP100L handles multi-gas and airborne particulate. If you are weighing gas-only versus combination cartridges, our organic vapor vs P100 guide and respirator filter types explained walk through when the integrated P100 is worth it.

Who Should Buy the 75SCP100L?

Buy it if your work mixes multi-gas with dust or mist. Choose another cartridge if your hazard is different: pick the gas-only 75SCL when there is no dust, or 7581P100L for organic vapor + P100 or 7583P100L for OV/AG + P100.

What Does the 75SCP100L Protect Against?

What the 75SCP100L Does NOT Protect Against

The 75SCP100L does not stop gases outside its NIOSH-approved list; for particulate alone the 7580P100 filter is enough.

No air-purifying cartridge makes a dangerous atmosphere safe. Never use the 75SCP100L in an oxygen-deficient or IDLH (immediately dangerous to life or health) atmosphere, in unknown concentrations, or against gases with no warning properties — those conditions require a supplied-air or SCBA system, not a cartridge respirator.

Best Applications

Maintenance & emergency response

Where the gas hazard is mixed or unknown and dust is present, the 75SCP100L is the safe default; see our best respirator for chemical workers guide.

Labs with particulate

Labs moving between solvents, acids, ammonia and formaldehyde plus dust use one cartridge. Compare gas-only in our 75SCL vs 75SCP100L guide.

Pros & Cons

75SCP100L vs Other North Cartridges

75SCP100L vs the Alternatives

How it stacks up against the closest North options:

• 75SCP100L vs 75SCL: same broad gas coverage, but the 75SCP100L adds a P100 filter for dust. Full comparison →
• 75SCP100L vs 7583P100L: the 75SCP100L adds ammonia and formaldehyde over the 7583P100L. Full comparison →
• 75SCP100L vs 7580P100: the 7580P100 is particulate only; the 75SCP100L adds the full gas mix.

75SCP100L Quick Answers

Does the 75SCP100L need a separate filter?

No — the P100 filter is built in, so there is no prefilter or retainer to add.

Does the 75SCP100L fit North 5500 and 7700 respirators?

Yes. The North bayonet connection fits the 5500 and 7700 series half masks and the 5400 and 7600 series full-face respirators.

Is the 75SCP100L cartridge reusable?

The cartridge is reusable until its gas or filter service life is reached; the respirator itself is reusable across many cartridge changes.

75SCP100L Specifications

Compatible North Respirators

The 75SCP100L uses the North bayonet connection, so it mounts on the North half-mask respirators (5500 and 7700 series) and North full-face respirators (5400 and 7600 series). It does not fit 3M or MSA facepieces.

75SCP100L Frequently Asked Questions

What does the Honeywell North 75SCP100L protect against?

The 75SCP100L is a multi-gas / P100 combination cartridge. It captures organic vapor, acid gas, ammonia, methylamine and formaldehyde and filters at least 99.97% of airborne particulate, covering gas plus dust, mist and fume. It does not protect against gases outside its NIOSH-approved list.

Does the Honeywell North 75SCP100L filter dust?

Yes. The 75SCP100L has a built-in P100 filter that captures at least 99.97% of airborne particles, including oil-based mists, so no separate prefilter is needed.

Which respirators does the Honeywell North 75SCP100L fit?

The 75SCP100L uses the North bayonet connection, so it fits North 5500 and 7700 series half-mask respirators and North 5400 and 7600 series full-face respirators. It does not fit 3M or MSA facepieces.

What does P100 mean on the 75SCP100L?

P100 is the highest NIOSH particulate rating: oil-proof and at least 99.97% efficient. The 75SCP100L carries a magenta P100 marking alongside its gas-class marking.

Is the Honeywell North 75SCP100L NIOSH-approved?

Yes. The 75SCP100L is NIOSH-approved under 42 CFR Part 84 for its listed gases and P100 particulate. You can verify any cartridge against the NIOSH Certified Equipment List.

How often should I replace the Honeywell North 75SCP100L?

Replace the gas portion on a documented change-out schedule or when you detect gas, and replace when breathing through the P100 filter becomes noticeably harder as particulate loads it.

Does the 75SCP100L need a separate filter?

No. The P100 particulate filter is built in, so there is no prefilter or retainer to add. The 75SCP100L cartridge is ready for both gas and particulate.

What is the difference between the 75SCP100L and the 75SCL?

Both cover the same gas, but the 75SCP100L adds a P100 particulate filter. Choose the 75SCL if there is no dust; the 75SCP100L when gas and particulate are both present.

What do the colors on the 75SCP100L mean?

The markings are olive (multi-gas) + magenta (p100); confirm both your gas class and the P100 on the cartridge color chart before use.

Is this the genuine Honeywell North 75SCP100L cartridge?

Yes. WC Safety sells authentic, NIOSH-approved Honeywell North 75SCP100L cartridges through legitimate supply channels, so you avoid the counterfeits common on open marketplaces.

Can I buy the 75SCP100L in bulk or by the case?

Yes. Use the Request a Quote option for case and pallet pricing on volume orders for crews, facilities and distributors.

How should I store the Honeywell North 75SCP100L?

Store it sealed in its original packaging, away from gases and dust, so neither the gas nor filter service life is used up before you wear it.
