Honeywell North N75003L Organic Vapor & Acid Gas Cartridge Overview

The Honeywell North N75003L is a NIOSH-approved, yellow-band cartridge that snaps onto North bayonet half- and full-face respirators to protect against both organic solvent vapors and acid gases such as chlorine, hydrogen chloride and sulfur dioxide. It is the two-in-one OV/AG cartridge in the North N-series for chemical handling, lab work and treatment tasks. If you are deciding which gas class you need, start with our guide to choosing a respirator cartridge and the Honeywell North cartridge guide, then confirm the color code on the respirator cartridge color chart.

As a Honeywell North organic vapor acid gas cartridge, the N75003L belongs to the Honeywell North respirator filters and cartridges family. Buy the N75003L cartridge when you face both solvent vapor and acid gas; choose a single-class cartridge if you face only one, or a different cartridge for ammonia or dust.

Where the N75003L Fits in Cartridge Selection

Confirm the hazards before the cartridge. The N75003L handles organic vapor and acid gas together — solvent fumes plus chlorine, HCl and SO2 — but not ammonia and not airborne particles. If you are weighing gas classes or adding dust protection, our organic vapor vs P100 guide and respirator filter types explained walk through the difference. When dust is also present, add a prefilter or move to a combination cartridge.

Who Should Buy the N75003L?

Buy it if your exposure is both organic vapor and acid gas — chemical plants, labs, and treatment work where solvents and chlorine-type gases mix. Choose another cartridge if your hazard is single-class or different: pick the N75001L for organic vapor only, the N75002L for acid gas only, the N75004L for ammonia, the 75SCL Defender for multi-gas, or add particulate with the 7583P100L OV/AG/P100 combination.

What Does the N75003L Protect Against?

What the N75003L Does NOT Protect Against

The N75003L does not stop ammonia (choose the N75004L), the broadest mix of gases (75SCL Defender), or particulate, which needs a 7580P100 filter.

No air-purifying cartridge makes a dangerous atmosphere safe. Never use the N75003L 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

Chemical handling & lab work

Tasks that mix solvents with chlorine-type acid gases are the N75003L's core use. See the broader options in our best respirator for chemical workers guide.

Treatment & maintenance

Where both vapor and acid gas appear, one OV/AG cartridge replaces carrying two. Compare the single-class options in our N75001L vs N75002L guide.

Pros & Cons

Compatible North Respirators

The N75003L 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). For dust as well, fit a North 7506-series prefilter over the cartridge. It does not fit 3M or MSA facepieces.

N75003L vs Other North Cartridges

N75003L vs the Alternatives

If you are weighing the N75003L against another North cartridge, the decision comes down to which hazards you face:

• N75003L vs N75001L: the N75003L adds acid gas; the N75001L is organic vapor only. See the class breakdown →
• N75003L vs 7583P100L: the N75003L is gas only; the 7583P100L builds in a P100 filter for OV/AG + dust. Full comparison →
• N75003L vs 75SCL Defender: the N75003L covers OV + acid gas; the 75SCL adds ammonia and more for the broadest gas mix.

N75003L Quick Answers

Is the Honeywell North N75003L reusable?

The cartridge is reusable until its service life is reached; replace it on schedule or when you detect vapor or gas. The respirator itself is reusable across many cartridge changes.

What color band is the N75003L?

Yellow — the NIOSH code for organic vapor plus acid gas. Match the band to the hazard with the cartridge color chart.

Does the N75003L 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 N75003L an organic vapor acid gas cartridge?

Yes — the N75003L organic vapor acid gas cartridge combines OV and AG protection in one yellow-band cartridge; add a prefilter or use the 7583P100L if dust is present.

Honeywell North N75003L Frequently Asked Questions

What does the Honeywell North N75003L protect against?

The N75003L is an OV/AG cartridge. It adsorbs organic solvent vapors plus acid gases such as chlorine, hydrogen chloride and sulfur dioxide, but not ammonia, dust, fume or oil mist.

Which respirators does the N75003L fit?

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

Does the N75003L filter dust or particulates?

No. The N75003L is a gas-and-vapor cartridge with no particulate filter. Fit a North 7506-series prefilter over it, or step up to the 7583P100L OV/AG/P100 combination.

What color band is the N75003L?

Yellow — the NIOSH color code for combined organic vapor and acid gas.

Is the N75003L NIOSH-approved?

Yes, for organic vapor and acid gas under 42 CFR Part 84. You can verify any cartridge against the NIOSH Certified Equipment List.

How often should I replace the N75003L?

Replace it on a documented change-out schedule, or sooner if you detect vapor or gas, get irritation, or breathing becomes harder. It has no end-of-service-life indicator.

What is the difference between the N75003L and the N75001L?

The N75003L covers organic vapor and acid gas; the N75001L is organic vapor only.

Can I use the N75003L for paint and chlorine together?

Yes — the OV/AG combination is built for both. For dust as well, add a North 7506-series prefilter or use the 7583P100L combination.

Is the N75003L the same as a particulate filter?

No. It is a gas cartridge, not a particulate filter. For dust and mist use a P100 such as the 7580P100, or the 7583P100L combo.

Is this the genuine Honeywell North N75003L cartridge?

Yes. WC Safety sells authentic, NIOSH-approved Honeywell North OV/AG cartridges through legitimate supply channels.

Can I buy the N75003L in bulk or by the case?

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

How should I store the N75003L?

Store it sealed in its original packaging, away from vapors and gases, so its service life is not used up before you wear it.
