Honeywell North 7506N95 N95 Prefilter Overview

The Honeywell North 7506N95 is a NIOSH-approved N95 prefilter disc that snaps onto North bayonet gas cartridges. It captures at least 95% of non-oil airborne particles and is not oil-resistant, adding particulate protection in front of the cartridge and extending its service life. Start with our respirator filter types explained and the organic vapor vs P100 guide to confirm the N95 class fits, then see the respirator cartridge color chart.

As a North prefilter, the 7506N95 prefilter belongs to the Honeywell North respirator filters and cartridges family. Read our hands-on Honeywell North 7506N95 review for field-tested detail. Use the 7506N95 over a North gas cartridge — it is not a standalone respirator.

Where the 7506N95 Fits

The 7506N95 adds particulate prefiltering to a North gas cartridge such as the N75001L or N75002L. For a higher particulate class, the 7580P100 is a full P100 filter, and the 7581P100L builds P100 into the cartridge itself.

What Does the 7506N95 Protect Against?

What the 7506N95 Does NOT Protect Against

The 7506N95 does not stop gases or vapors on its own, and it is not a respirator by itself. It must be used over a North gas cartridge; for a full P100 use the 7580P100.

No air-purifying cartridge makes a dangerous atmosphere safe. Never use the 7506N95 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

Extending cartridge life in dusty work

Where dust would quickly clog a gas cartridge, the 7506N95 prefilter takes the particulate load so you change the cheap disc, not the cartridge.

Adding particulate to a gas task

Snap the 7506N95 onto a North gas cartridge to add N95 particulate protection; compare classes in our filter types guide.

• 7506N95 vs 7580P100: the 7580P100 is a full P100 filter (99.97%, oil-proof); the 7506N95 is a N95 prefilter that extends a cartridge. Full comparison →
• 7506N95 vs 7581P100L: the 7581P100L builds P100 into an OV cartridge; the 7506N95 is a separate prefilter for a gas cartridge.

7506N95 Quick Answers

Does the 7506N95 need a retainer?

No — it snaps directly onto a North cartridge such as the N75001L with its own cover.

Is the 7506N95 a respirator by itself?

No — it is a prefilter used over a North gas cartridge like the N75002L; browse the full North cartridge range.

Does the 7506N95 fit North 5500 and 7700 respirators?

Yes — it fits North bayonet cartridges such as the 75SCL and N75003L.

When should I step up to a P100?

When you need at least 99.97% or oil-proof particulate, move to the 7580P100 filter or a 7581P100L combination cartridge.

7506N95 Specifications

Compatible North Respirators

The 7506N95 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.

7506N95 Frequently Asked Questions

What does the Honeywell North 7506N95 do?

The 7506N95 is a N95 prefilter disc that snaps onto a North gas cartridge. It captures at least 95% of non-oil airborne particles, adding particulate protection and extending the gas cartridge's life.

Does the 7506N95 replace a cartridge?

No. The 7506N95 prefilter is used over a North gas cartridge, not on its own. It adds particulate filtering in front of the cartridge.

How does the 7506N95 attach?

It snaps directly onto the front of a North bayonet cartridge with its built-in cover — no separate retainer is needed.

Which cartridges does the 7506N95 fit?

The 7506N95 fits North bayonet gas cartridges such as the N75001L, N75002L and 75SCL, on North 5500/7700 and 5400/7600 respirators.

What does N95 mean on the 7506N95?

N95 is a NIOSH particulate rating: at least 95% of non-oil airborne particles. Is not oil-resistant.

Is the Honeywell North 7506N95 NIOSH-approved?

Yes. The 7506N95 is a NIOSH-approved N95 prefilter under 42 CFR Part 84. You can verify it against the NIOSH Certified Equipment List.

How often should I replace the 7506N95?

Replace the prefilter when it is loaded, soiled or damaged, or when breathing resistance rises — changing it protects and extends the gas cartridge behind it.

Does the 7506N95 stop gases?

No. It is a particulate prefilter; the gas cartridge it snaps onto provides the vapor protection.

Why use a prefilter at all?

A prefilter captures dust before it reaches the gas cartridge, so the cartridge lasts longer and you change the cheaper disc more often than the cartridge.

Is this the genuine Honeywell North 7506N95 prefilter?

Yes. WC Safety sells authentic, NIOSH-approved Honeywell North 7506N95 prefilters through legitimate supply channels.

Can I buy the 7506N95 in bulk or by the case?

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

How should I store the 7506N95?

Store it sealed in its original packaging, away from dust and moisture, so its service life is not used up before use.
