Honeywell North N75002L Acid Gas Cartridge Overview

The Honeywell North N75002L acid gas cartridge is a NIOSH-approved, white-band cartridge that snaps onto North bayonet half- and full-face respirators to protect against acid gases such as chlorine, hydrogen chloride and sulfur dioxide. It is the dedicated acid gas cartridge in the North N-series for water treatment, plating, etching and chemical handling. 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 acid gas cartridge, the N75002L belongs to the Honeywell North respirator filters and cartridges family. Buy it when your hazard is acid gas; choose a different cartridge if you face organic vapor, ammonia or dust.

Where the N75002L Fits in Cartridge Selection

Confirm the hazard before the cartridge. The N75002L handles acid gas — chlorine, HCl, SO2 — but not organic solvent vapor 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 acid gas and dust are both present, add a prefilter or move to a combination cartridge.

Who Should Buy the N75002L?

Buy it if your exposure is acid gas only — chlorine rooms, water and wastewater treatment, plating and etching lines. Choose another cartridge if your job adds a second hazard: pick the N75001L for organic vapor, the N75003L for organic vapor plus acid gas, the 75SCL Defender for multi-gas, or add particulate with the 7582P100L AG/P100 combination.

What Does the N75002L Protect Against?

What the N75002L Does NOT Protect Against

The N75002L does not stop organic vapor (choose the N75001L), ammonia (N75004L), a broad mix of gases (75SCL Defender), or particulate, which needs a 7580P100 filter.

No air-purifying cartridge makes a dangerous atmosphere safe. Never use the N75002L 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

Water & wastewater treatment

Chlorine and chlorine-dioxide handling in water and wastewater plants is the N75002L's core use. See the broader options in our best respirator for chemical workers guide.

Plating, etching & chemical handling

Acid baths and etching lines release HCl and SO2 the N75002L captures. If solvent vapor is also present, compare the combination options in our N75001L vs N75002L guide.

Pros & Cons

Compatible North Respirators

The N75002L 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.

N75002L vs Other North Cartridges

N75002L vs the Alternatives

If you are weighing the N75002L against another North cartridge, the decision comes down to how many hazards you face:

• N75002L vs N75001L: the N75002L is acid gas only; the N75001L is organic vapor only. Full comparison →
• N75002L vs 7582P100L: the N75002L is gas only; the 7582P100L builds in a P100 filter for acid gas + dust. Full comparison →
• N75002L vs N75003L: the N75002L covers acid gas; the N75003L adds organic vapor for combined exposures.

N75002L Quick Answers

Is the Honeywell North N75002L reusable?

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

What color band is the N75002L?

White — the NIOSH code for acid gas. Match the band to the hazard with the cartridge color chart.

Does the N75002L 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 N75002L good for chlorine?

Yes — chlorine is an acid gas the N75002L is built for, with HCl and SO2; add a prefilter or use the 7582P100L if dust is present.

Honeywell North N75002L Frequently Asked Questions

What does the Honeywell North N75002L protect against?

The N75002L is an acid gas cartridge. It adsorbs chlorine, hydrogen chloride, sulfur dioxide and hydrogen fluoride, but not organic vapor, ammonia, dust, fume or oil mist.

Which respirators does the N75002L 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 N75002L filter dust or particulates?

No. The N75002L is a gas-and-vapor cartridge with no particulate filter. Fit a North 7506-series prefilter over it, or step up to the 7582P100L AG/P100 combination.

What color band is the N75002L?

White — the NIOSH color code for acid gas. Every NIOSH-approved acid gas cartridge carries a white band.

Is the N75002L NIOSH-approved?

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

How often should I replace the N75002L?

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

What is the difference between the N75002L and the N75001L?

The N75002L is acid gas only; the N75001L is organic vapor only. Choose the N75003L if you need both.

Can I use the N75002L for chlorine?

Yes — chlorine is an acid gas the N75002L is designed for. For acid gas with dust, use the 7582P100L combination.

Is the N75002L 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 7582P100L combo.

Is this the genuine Honeywell North N75002L cartridge?

Yes. WC Safety sells authentic, NIOSH-approved Honeywell North acid gas cartridges through legitimate supply channels.

Can I buy the N75002L 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 N75002L?

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