MSA SparkFoe P100 Particulate Filter Overview

The MSA SparkFoe P100 Filter is a NIOSH-approved SparkFoe P100 particulate filter for MSA Comfo respirators. It captures at least 99.97% of airborne particles and is oil-proof. Its spark-resistant, static-dissipating SparkFoe construction is built for welding and grinding. Start with our filter types explained and organic vapor vs P100 guides, then confirm fit in Comfo vs Advantage.

As an MSA Comfo P100 filter it belongs to the MSA respirator filters and cartridges range. Use it for particulate-only work, or pair it with an MSA gas cartridge when vapors are present.

Where the MSA SparkFoe P100 Filter Fits

The MSA SparkFoe P100 Filter handles airborne particulate only. For gases you need an MSA cartridge such as the GMA organic vapor or GMB acid gas, or a combination cartridge like the GMA/P100.

What Does the MSA SparkFoe P100 Filter Protect Against?

What the MSA SparkFoe P100 Filter Does NOT Protect Against

The MSA SparkFoe P100 Filter does not capture gases or vapors. Add the GMA for organic vapor, the GMB for acid gas, or use the all-in-one GMA/P100.

No air-purifying cartridge makes a dangerous atmosphere safe. Never use the MSA SparkFoe P100 Filter 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

Welding & grinding

The SparkFoe design resists sparks and dissipates static while the P100 captures weld fume.

Hot work

Tasks with airborne sparks where a standard filter could be damaged.

Pros & Cons

MSA SparkFoe P100 Filter vs Other MSA Filters & Cartridges

MSA SparkFoe P100 Filter vs the Alternatives

How it compares to the closest MSA options:

• MSA SparkFoe P100 Filter vs GMA/P100: this filter is particulate only; the GMA/P100 builds the same P100 into an organic-vapor cartridge.
• MSA SparkFoe P100 Filter vs standard Low Profile P100: the SparkFoe adds spark and static resistance for welding; the standard filter is for general particulate.
• MSA SparkFoe P100 Filter vs an MSA gas cartridge: a gas cartridge stops vapors; this filter stops particulate — many jobs need both.

MSA SparkFoe P100 Filter Quick Answers

Does the MSA SparkFoe P100 Filter stop gases?

No — pair it with an MSA gas cartridge such as the GMA for vapors.

Does the MSA SparkFoe P100 Filter fit my MSA respirator?

It fits the MSA Comfo family; check the half-mask and full-face ranges.

Is the MSA SparkFoe P100 Filter oil-proof?

Yes — P100 is the oil-proof particulate class.

MSA SparkFoe P100 Filter Specifications

Compatible MSA Respirators

The MSA SparkFoe P100 Filter uses the MSA Comfo threaded-bayonet connection, so it mounts on the Comfo Classic half-mask and Ultra-Elite full-face respirators (and the Comfo II and Ultra-Twin). It is not interchangeable with the MSA Advantage series, and does not fit 3M, Honeywell North or other brands.

MSA SparkFoe P100 Filter Frequently Asked Questions

What does the MSA SparkFoe P100 Filter protect against?

It is a P100 particulate filter: it captures at least 99.97% of airborne particles — dust, mist, fume, lead — and is oil-proof. It does not filter gases on its own.

Does the MSA SparkFoe P100 Filter protect against gases?

No. For gases or vapors, pair it with an MSA gas cartridge such as the GMA (organic vapor), or use a combination cartridge like the GMA/P100.

Which respirators does the MSA SparkFoe P100 Filter fit?

It fits MSA Comfo-series respirators (Comfo Classic, Comfo II, Ultra-Twin, Ultra-Elite).

What does P100 mean?

P100 is the highest NIOSH particulate rating: oil-proof and at least 99.97% efficient. The filter carries a magenta marking.

Is the MSA SparkFoe P100 Filter oil-proof?

Yes. P100 filters are oil-proof, so it can be used against oil-based mists as well as solid particulate.

Can I use the MSA SparkFoe P100 Filter for welding?

Yes — the SparkFoe design resists sparks and dissipates static, so it suits welding and grinding while the P100 captures weld fume.

Is the MSA SparkFoe P100 Filter NIOSH-approved?

Yes, as a P100 filter under 42 CFR Part 84. Verify against the NIOSH Certified Equipment List.

How is the MSA SparkFoe P100 Filter sold?

This listing is the 2-pack. Use Request a Quote for larger case quantities.

How often should I replace the MSA SparkFoe P100 Filter?

Replace it when breathing resistance rises as particulate loads it, or when it is damaged or soiled.

Is the MSA SparkFoe P100 Filter reusable?

The filter is used until its particulate service life is reached; the respirator is reusable across many filter changes.

Is this the genuine MSA SparkFoe P100 Filter?

Yes. WC Safety sells authentic, NIOSH-approved MSA Comfo filters through legitimate supply channels.

How should I store the MSA SparkFoe P100 Filter?

Store it sealed in its original packaging, away from dust and moisture.
