Honeywell North 75SCP100L P100 respirator cartridges, pair
The Honeywell North 75SCP100L Defender combines a multi-contaminant gas and vapor cartridge with a P100 particulate filter. Sold by ASA as a pair under SKU S75SCP100L, it is a replacement cartridge set for compatible North reusable respirators. The facepiece is purchased separately. Each pair supplies the two cartridges for one compatible respirator.
Choose this combination when your respiratory protection program calls for its listed gas and vapor coverage alongside particulate filtration. The specific model number matters: North offers several cartridges with different protection types, even when their housings look similar.
What this model provides
- Combined gas, vapor, and particulate filtration.
- P100 filtration for oil and non-oil particles.
- Low-profile housing with a curved upper edge.
- Threaded attachment to compatible North facepieces.
Before ordering
- Match the complete 75SCP100L model number.
- Confirm the approved facepiece and cartridge combination.
- Check identified contaminants and exposure concentrations.
- Order by pairs for scheduled replacement.
Multi-contaminant coverage with P100 filtration
The manufacturer's selection chart lists organic vapors, ammonia, methylamine, formaldehyde, chlorine, hydrogen chloride, sulfur dioxide, hydrogen sulfide, chlorine dioxide, and hydrogen fluoride for the Defender combination. Hydrogen sulfide use is limited to escape; it is not permission to enter an exposure area. Always follow the complete assembly's approval and use restrictions.
The P100 component provides at least 99.97% particulate filtration efficiency under the applicable test conditions. That percentage describes the filter, not the percentage of every workplace contaminant removed from a wearer's breathing zone. Gas and vapor suitability comes from the cartridge's specific approvals, while fit and exposure conditions determine whether the respirator assembly is appropriate.
Fits compatible North reusable respirators
Honeywell documents threaded compatibility with North 5500 and 7700 half masks and 5400 and 7600 full facepieces. Confirm your exact assembly against the supplied approval label and instructions before installation. These are North N-Series connections, not universal fittings for other respirator brands.
The low-profile shape helps keep the cartridges out of the immediate work zone. A curved upper edge reduces opportunities to catch against nearby objects, and the inlet arrangement supports user seal checks. Those design details can matter when comparing replacement cartridges for an existing approved North respirator.
Combination cartridges versus particulate-only filters
A particulate-only P100 filter does not provide the Defender's listed gas and vapor protection. Conversely, a gas and vapor cartridge without a particulate filter does not become P100 simply because it fits the same mask. The 75SCP100L combines both functions in one cartridge assembly.
For purchasing teams, recording the model number beside the issued facepiece helps prevent substitutions based only on appearance or the word P100. Select coverage for the actual exposure assessment; a broader contaminant list does not make a cartridge suitable for every chemical or task.
Replacement planning and storage
Use the cartridge change schedule established by your respiratory protection program from objective service-life information. Do not wait for odor or taste to decide when to replace gas and vapor cartridges. Exposure concentration, humidity, work rate, and other conditions affect service life, so there is no universal number of shifts for this pair.
Keep unused cartridges protected from contamination and follow the storage conditions and expiration information on their packaging. Inspect components before installation. Leave the exposure area and follow your program's response procedure if the respirator is damaged, breathing becomes difficult, or breakthrough is suspected.
Review the manufacturer cartridge selection guide alongside your respirator instructions.
North 75SCP100L cartridge FAQ
Is a respirator mask included?
No. This listing supplies two replacement cartridges. A compatible facepiece is required separately.
Does P100 mean protection against every gas?
No. P100 identifies particulate filtration. Gas and vapor coverage depends on the specific cartridge model.
Will these fit my North 7700?
The 7700 is among the North facepiece series listed for this threaded cartridge family. Verify the complete approved configuration and your workplace selection before use.
How should I identify replacement stock?
Use manufacturer model 75SCP100L and ASA SKU S75SCP100L on your purchasing record. The olive and magenta identification indicates the combination category, but color alone is not a sufficient ordering reference. Check the printed model number on each package when receiving stock, and retain the packaging information with your inventory records so the next order matches the cartridge selected for your workers.
