Is the 3M Powerflow 6800PF HE SP3 Particulate Filter the right replacement HE filter for your 6800PF face-mounted PAPR?

Short answer: If you run the 3M Powerflow 6800PF face-mounted PAPR, this SP3 filter (OEM 450-01-01) is the only genuine particulate filter that fits it, so the buying decision is mostly "yes, this one." Just be clear it is a high-efficiency particulate filter — P100-class for dusts, mists and fumes — with no gas or vapor protection, and it is sold as a case of 20, which is volume-priced for programs rather than a single-pair grab. Cross-shoppers comparing PAPR systems should note the 6800PF uses this proprietary filter, not the TR-series or Adflo cartridges.

3M Powerflow 6800PF HE SP3 Particulate Filter Review (2026)

This is a consumable, not a respirator: the 3M Powerflow 6800PF HE SP3 Particulate Filter (OEM 450-01-01, ordered as case-of-20 part 450-01-01R20) is the replacement filtration media for the 3M Powerflow 6800PF face-mounted PAPR — the compact, belt-free powered respirator that integrates a motor-blower and HE filter onto a 3M 6800 full facepiece. By itself the filter carries no assigned protection factor; it is the media the 6800PF's blower pulls air through, and the system's OSHA APF 1000 (when used per 3M's instructions with a fit-tested full facepiece) depends on this genuine HE element being installed and changed on schedule. Compatibility is platform-specific and narrow: the SP3 fits the Powerflow 6800PF only — it is not a TR-300/TR-300N filter, not a TR-600/TR-800 filter, and not an Adflo welding filter. It is HE/P100-class for particulates (dusts, mists, fumes, lead, asbestos, mold, radionuclides) and provides zero gas or vapor protection — for that you would need a different platform, since the 6800PF is approved for HE filters only. For background on powered respirators and how their filters work, see what is a PAPR and N95 vs P100."

Editorial verdict — 4.3/5
As the sole OEM filter for the 6800PF, it is essentially mandatory rather than optional — the cost question is pack economics (case of 20 at roughly $400) and change-out cadence, not whether to buy it.VIEW ON WC SAFETY →CHECK PRICE ON AMAZON →

Who it is for

• Facilities running the 3M Powerflow 6800PF face-mounted PAPR that need genuine replacement HE filters
• Lead-abatement, asbestos and mold-remediation crews whose hazard is purely particulate and who own 6800PF units
• Foundry, grinding and metal-fume operations standardized on the 6800PF platform
• Safety managers stocking a case of 20 to cover a fleet of 6800PF respirators
• Programs needing a fixed, NIOSH-recognized PAPR filter line item for their respiratory protection program
• Buyers who do NOT need gas/vapor protection — those who do should pick a different PAPR system

What the 3M Powerflow 6800PF SP3 HE Filter does well

Exact, unambiguous compatibility

There is no guesswork: the SP3 (450-01-01) is the genuine particulate filter for the 3M Powerflow 6800PF and nothing else. Because the 6800PF is a self-contained face-mounted system, you avoid the cross-series mistakes that plague TR-series buyers who confuse TR-300 and TR-600 filters.

True high-efficiency particulate capture

This is HE media (P100-class, ~99.97% efficient) targeting dusts, mists, fumes and the named hazards on the 6800PF listing — lead, asbestos, mold and radionuclides. For how HE/P100 compares to lower particulate ratings, see N95 vs P100.

Protects the system's high APF

The 6800PF's OSHA APF 1000 (tight-fitting full facepiece, fit-tested, used per 3M instructions) only holds when a genuine HE filter is installed. Using OEM media is part of keeping the NIOSH 42 CFR 84 approval intact rather than voiding it.

Program-friendly case packaging

At a case of 20 (~$400.35, roughly $20 per filter), it is priced for fleets and stocking, not impulse single buys. That makes it easy to drop into a written respiratory protection program and a recurring purchase cadence.

Simple to install

As a face-mounted system component the SP3 seats directly on the 6800PF blower — there is no separate retainer or adapter to source. Pair good filter hygiene with the broader habits in respirator maintenance, inspection and storage.

Where the 3M Powerflow 6800PF SP3 HE Filter falls short

No chemical protection whatsoever

This is a particulate-only HE filter. If your exposure includes solvents, acid gas, formaldehyde or ammonia, the 6800PF/SP3 combination is the wrong tool — you would need a different PAPR system with the matching gas/vapor cartridge. See why can I smell chemicals through my respirator and how to choose a respirator cartridge.

Platform lock-in

The SP3 fits the Powerflow 6800PF and only the 6800PF. It is not interchangeable with TR-300/TR-300N HE filters, TR-600/TR-800 HE filters, or Adflo — so this filter is only useful if you are committed to the 6800PF.

Case-of-20 minimum

There is no documented single-filter retail pack here; the listing is a case of 20 at ~$400. An individual owner of one 6800PF who wants a single spare is over-buying, and a small shop should weigh that outlay against the full PAPR systems it could otherwise fund.

No published hours rating

3M frames replacement around its change schedule rather than a fixed service-life number, so you cannot read a guaranteed run-time off the box. You must set cadence yourself — see respirator cartridge change-out schedule.

When to step up from the 3M Powerflow 6800PF SP3 HE Filter

If your work ever extends beyond particulates, the SP3 is not a "step up" path — the 6800PF is approved for HE filters only, so the real step up is a different platform. The closest comparable industrial route is the Versaflo TR-600 or TR-800 systems, which accept the TR-6710N HE filter for particulates and a range of gas/vapor cartridges such as the TR-6510N organic vapor/HE or TR-6530N OV/acid gas/HE. For welding, the step-across is the Speedglas G5-01 with Adflo and its Adflo media. Within the 6800PF world itself, the only "upgrade" is disciplined stocking and change-out — buy the case of 20, keep charged spares, and follow your change-out schedule.

Category context

Two distinctions decide whether this filter is right for you. First, HE/particulate vs gas/vapor: the SP3 is a high-efficiency particulate filter (P100-class) and stops solid and liquid aerosols — dusts, mists, fumes, lead, asbestos, mold — but does nothing against chemical gases or vapors. If you can smell solvents through a particulate filter, that is expected, not a defect; see why can I smell chemicals through my respirator and how to read a respirator cartridge label. Second, series compatibility: 3M's PAPR filters are platform-specific by design. The SP3 (450-01-01) belongs to the Powerflow 6800PF; the TR-3712N belongs to TR-300/TR-300N; the TR-6710N belongs to TR-600/TR-800. They are not interchangeable, and mixing them voids the NIOSH approval. Because the 6800PF is a tight-fitting full facepiece, it also carries fit-test and seal-check obligations loose-fitting hoods do not — review respirator fit testing and how to seal check a respirator, and confirm your duties under OSHA 29 CFR 1910.134."

Total cost of ownership

Filter economics here are straightforward but program-scale. The SP3 ships as a case of 20 at roughly $400.35 — about $20 per filter — so total cost of ownership is driven by how fast you go through filters, which is set by your loading conditions and your change-out schedule, not by a printed hours number. In heavy, dusty work (foundry, abrasive blasting-adjacent grinding, abatement) particulate filters load and restrict airflow faster, so cost-per-shift climbs; in lighter exposures a case lasts much longer. To protect that spend, treat the SP3 as the last line and let cheaper prefilters take the brunt where your platform supports them, keep filters sealed and dry per maintenance, inspection and storage, and watch shelf life so stocked cases do not expire before use. For a fleet, a case of 20 is usually the right buy; for a single 6800PF you should size purchasing to realistic annual usage rather than over-stocking. Compare this against the running cost of a TR-series system before committing a program to the 6800PF long-term.

Final verdict

Buy the 3M Powerflow 6800PF SP3 HE filter if — and only if — you run the 3M Powerflow 6800PF face-mounted PAPR and your hazard is particulate (lead, asbestos, mold, metal fume, general dust). For those owners it is the genuine, NIOSH-recognized replacement media and an easy, near-mandatory reorder; a case of 20 is the sensible stocking quantity for a fleet, with single owners sizing to real usage. Skip it if you need any gas or vapor protection — move to a TR-600/TR-800 system with the matching cartridge instead — or if you are on a different platform entirely, in which case use the TR-300/TR-300N, TR-600/TR-800 or Adflo media that fits your blower.

3M Powerflow 6800PF SP3 HE Filter FAQ

What PAPR does the 3M Powerflow SP3 filter fit?

It fits the 3M Powerflow 6800PF face-mounted PAPR and nothing else. The SP3 (OEM 450-01-01) is a system-specific component for that platform, so it will not work on the TR-300/TR-300N, TR-600/TR-800, or Adflo systems. Always match the filter to your exact PAPR system.

Is the SP3 a HEPA or P100 filter?

It is a high-efficiency (HE) particulate filter, the PAPR equivalent of P100-class media, capturing roughly 99.97% of particulates. It is rated for dusts, mists, fumes, lead, asbestos, mold and radionuclides. For how HE/P100 compares to lower particulate ratings, see N95 vs P100.

Does the SP3 filter protect against gases or vapors?

No. It is a particulate-only filter with no organic vapor, acid gas or other chemical protection. If your work involves solvents or other chemicals, you need a gas/vapor cartridge on a compatible platform — the 6800PF is approved for HE filters only. See how to choose a respirator cartridge.

Why is it sold as a case of 20?

The listed pack is a case of 20 system components (part 450-01-01R20) at about $400.35, which is volume packaging aimed at programs and fleets. That works out to roughly $20 per filter. A single 6800PF owner can still buy it but should size purchasing to realistic usage rather than over-stocking.

Can I use a generic or third-party filter instead?

Not without consequences. Only the genuine 3M SP3 (450-01-01) preserves the 6800PF's NIOSH 42 CFR 84 approval; substituting a non-OEM filter voids that approval and your assigned protection factor. Stick to the OEM component for any compliant respiratory protection program.

How often should I change the SP3 filter?

3M points to its change schedule rather than a fixed hours number, so cadence depends on your loading conditions and written program. Particulate filters are typically changed when breathing or airflow resistance rises, when damaged, or on your set schedule — see respirator cartridge change-out schedule.

What APF does the SP3 filter provide?

The filter itself carries no assigned protection factor — APF is a property of the complete respirator. On the 6800PF, a tight-fitting full facepiece used per 3M instructions and fit-tested carries an OSHA APF of 1000, and a genuine HE filter is required to keep that figure valid. Background: what is a PAPR.

Will the SP3 fit a 3M Versaflo TR-600?

No. The TR-600 (and TR-800) use the TR-6710N HE filter and related cartridges, not the Powerflow SP3. 3M PAPR media is series-specific; never cross a 6800PF filter onto a Versaflo blower.

Will the SP3 fit a 3M Versaflo TR-300 or TR-300N?

No. The TR-300 and TR-300N use the TR-3712N HE filter. The SP3 is exclusive to the Powerflow 6800PF, so the platforms are not interchangeable.

Does the 6800PF need a fit test with this filter?

Yes — but that is a property of the respirator, not the filter. The 6800PF is a tight-fitting full facepiece, so it requires fit testing and seal checks regardless of which HE filter is installed. Review respirator fit testing and how to seal check a respirator.

Is the Powerflow 6800PF a loose-fitting or tight-fitting respirator?

It is tight-fitting — it is built on the 3M 6800 full facepiece, so it seals to the face and needs fit testing, unlike loose-fitting hood PAPRs. That tight seal is what enables its high APF. If you cannot pass a fit test (for example due to facial hair), consider a loose-fitting hood system from the PAPR collection instead.

Do I need a prefilter with the SP3?

Using prefilters where your platform supports them can extend the life of the more expensive HE filter by catching coarse debris first. It is a cost-management habit rather than a substitute for the HE filter. Pair it with disciplined change-out scheduling and good storage.

What is the OEM part number for this filter?

The filter is OEM 450-01-01, ordered as case-of-20 part number 450-01-01R20. Always specify the OEM number when reordering for your 6800PF to avoid receiving the wrong PAPR filter.

Does the SP3 expire on the shelf?

Filters have storage limits, so a stocked case should be used in date order and kept sealed, cool and dry. Don't let a large case of 20 sit past its usable window — see respirator cartridge shelf life and maintenance, inspection and storage.

Is the SP3 the right filter for asbestos or lead abatement?

For the particulate hazard, yes — the 6800PF listing names lead, asbestos, mold and radionuclides, and the SP3 is its HE particulate media. Confirm your overall program meets OSHA 29 CFR 1910.134 and any substance-specific standards, and document everything in your written respiratory protection program.

Can the 6800PF be used for welding fume with this filter?

It is a particulate HE filter, so it addresses particulate fume, but dedicated welding PAPRs offer integrated arc-flash protection the 6800PF does not. Welders are usually better served by a PAPR welding helmet such as the Speedglas G5-01 with Adflo.

How does the SP3 compare to a TR-series HE filter?

They are functionally the same class of media — high-efficiency particulate — but built for different blowers and not interchangeable. The SP3 is for the 6800PF; the TR-3712N is for TR-300/TR-300N and the TR-6710N is for TR-600/TR-800. Pick the one matching your PAPR system.
