Is the CleanSpace WORK HEPA Particulate Filter (3-Pack) the right replacement HE filter for your CleanSpace WORK Kit powered respirator?

Short answer: If you run the CleanSpace WORK Kit powered half-mask respirator, yes — this is the genuine CS3022WORK HEPA particulate filter, and buying OEM is the only way to keep the unit's NIOSH approval and 99.97% efficiency intact. It is a particulate-only filter (dust, mists, fumes), so if your hazard includes solvent vapors or acid gas you need a different platform entirely — see our PAPR cartridges and how to choose a respirator cartridge.

CleanSpace WORK HEPA Particulate Filter (3-Pack) Review (2026)

This is a consumable, not a respirator: the CleanSpace WORK HEPA Particulate Filter (3-pack, part CS3022WORK) is the genuine OEM particulate media that screws into the CleanSpace WORK Kit — CleanSpace's compact, hose-free powered respirator where the blower sits directly on the half mask. Filtration is HEPA-class at 99.97% efficiency, which puts it in the same particulate league as a P100; for the distinction see our explainer on N95 vs P100 respirators and the primer on what a PAPR is. Crucially, compatibility is platform-specific: this filter fits the CleanSpace WORK Kit (all mask sizes) and nothing else — it does not fit 3M Versaflo, Adflo, RPB PX5, Optrel e3000X, or any other system. It is also particulate-only, so it captures dust, mists and fumes but does nothing for gas or vapor hazards.

Editorial verdict — 4.4/5
At roughly $31 per filter in the 3-pack, the genuine CS3022WORK is fairly priced for an OEM HEPA media and the only correct consumable for the WORK Kit — buy it, but never let the platform's particulate-only limit catch you out on a gas or vapor job.VIEW ON WC SAFETY →CHECK PRICE ON AMAZON →

What the CleanSpace WORK HEPA Filter (3-Pk) does well

Protection performance

At 99.97% efficiency the CS3022WORK sits in HEPA/P100 territory for particulates — dust, mists and fumes are captured at the level you'd expect from a top-tier negative-pressure P100 cartridge, but with the comfort of powered airflow.

Genuine-OEM assurance

Because it is the manufacturer's own filter, the CS3022WORK preserves the CleanSpace WORK Kit's NIOSH approval — third-party media voids the approval and is a finding waiting to happen under OSHA 1910.134.

Easy change-out

Replacement is a tool-free drop-in onto the WORK power unit, and the unit's end-of-life indicator tells you when to swap rather than relying on a guessed change-out schedule.

Spares-friendly packaging

Selling in a 3-pack matches how PAPR programs actually run — you keep charged batteries and fresh filters on hand so a powered respirator is never sidelined for a missing consumable.

Compatibility clarity

There is no ambiguity here: this filter fits the CleanSpace WORK Kit in all mask sizes and only that platform, which removes the cross-series mix-up risk you see when shopping PAPR filters across brands.

Where the CleanSpace WORK HEPA Filter (3-Pk) falls short

No gas or vapor capability

This is a particulate filter, full stop. If your exposure includes organic vapor, acid gas, ammonia or formaldehyde, the CS3022WORK does nothing for it — you would need a cartridge platform like the PAPR cartridges collection, and the WORK Kit isn't built for that. See why you can smell chemicals through a respirator.

Single-platform lock-in

Proprietary fitment means you're committed to CleanSpace consumables for the life of the unit — there's no swapping in a cheaper or differently-rated filter the way some open ecosystems allow.

No bundled prefilter

Heavy dust loading can clog HEPA media quickly, and unlike some 3M Versaflo setups there's no prefilter in this pack to extend life — budget for shorter intervals in abrasive work and track it in your change-out schedule.

OEM price premium

Per-filter cost runs above commodity P100 discs because it's a single-source part; the trade-off is approval integrity, but it does push your cost of ownership up versus open-platform systems.

When to step up from the CleanSpace WORK HEPA Filter (3-Pk)

There is no higher filtration tier for this platform — HEPA 99.97% is the ceiling and the only particulate option for the WORK Kit, so the real "step up" is a platform decision, not a filter upgrade. If you find you regularly need gas or vapor protection alongside particulates, the step is to a cartridge-capable system: 3M's TR-600 series accepts OV/HE, acid gas/HE and multi-gas/HE cartridges, and the RPB PX5 offers both HEPA and gas/vapor media. Compare full systems in the best PAPR systems guide before assuming a filter swap will solve a vapor problem.

Category context

The choice between an HE/particulate filter like this and a gas/vapor cartridge is the single most important decision in PAPR consumable selection, and it is governed entirely by your hazard — not your preference. The CS3022WORK is an HE (HEPA, ≈P100-class) particulate filter: it removes dust, mists and fumes but is transparent to solvent vapors, acid gases, ammonia and formaldehyde, which only a matching PAPR cartridge can address. Use a respirator cartridge label and your air-monitoring data to confirm you have a particulate-only exposure before relying on this filter; the N95 vs P100 explainer and how to choose a respirator cartridge walk through that logic. Series compatibility is the second hard rule: PAPR filters are not interchangeable across brands or even within a brand's series (3M's TR-300 filters differ from TR-600 filters), so the CleanSpace WORK filter belongs to the CleanSpace WORK Kit alone — confirm the platform line in your written respiratory protection program.

Total cost of ownership

At $92.93 for three filters, the CS3022WORK works out to roughly $31 per filter, and your real cost of ownership is driven by how fast you load the HEPA media. Clean, low-dust environments stretch each filter toward its end-of-life indicator, while grinding, sanding or remediation work clogs media faster and pulls your change-out interval in — and because this pack ships without a prefilter, there's no sacrificial layer to protect the HEPA element the way a 3M Versaflo prefilter does on those platforms. Track replacements against a documented cartridge change-out schedule and watch shelf life on stocked spares so a 3-pack bought ahead doesn't age out before use. Buying genuine is the cost that protects every other dollar in the program: off-brand media voids the NIOSH approval and turns a compliant respirator into an OSHA 1910.134 liability.

Final verdict

If you own the CleanSpace WORK Kit and your hazard is particulate — dust, mists or fumes from grinding, sanding, remediation or general fabrication — this genuine CS3022WORK 3-pack is the correct, buy-it consumable, and the 3-pack is the right quantity for a spares-ready program. If your work ever puts you in front of solvent vapors, acid gas or other gas/vapor hazards, do not try to make this filter stretch; move to a cartridge-capable platform such as the 3M Versaflo TR-600 with the matching gas/vapor cartridge, or the RPB PX5. For owners of other systems, match the filter to your blower series via the PAPR filters collection and the best PAPR systems guide rather than cross-shopping by price.

CleanSpace WORK HEPA Filter (3-Pk) FAQ

Does the CleanSpace WORK HEPA filter fit any other PAPR brand or system?

No. The CS3022WORK fits only the CleanSpace WORK Kit powered respirator, across all of its mask sizes. PAPR filters are platform-specific and are not interchangeable with 3M Versaflo, Adflo, RPB PX5, Optrel e3000X or any other system — always match the filter to your exact blower, as explained in how to choose a respirator cartridge.

Is this a HEPA or a P100 filter, and what's the difference?

It is a HEPA-class particulate filter rated at 99.97% efficiency, which is essentially equivalent to a P100 for particulate capture. The labeling differs by standard, but both describe the highest particulate-filtration tier. Our N95 vs P100 explainer covers the distinctions and where each is appropriate.

Will this filter protect me from solvent vapors or chemical gases?

No — it is a particulate-only filter. It captures dust, mists and fumes but provides zero protection against organic vapor, acid gas, ammonia or formaldehyde. For those hazards you need a matching cartridge platform; see the PAPR cartridges collection and why you can smell chemicals through your respirator.

How many filters come in the pack and what's the per-filter cost?

The CS3022WORK ships as a 3-pack, which works out to roughly $31 per filter. The 3-pack quantity supports a spares-ready program so a powered respirator is never down for a missing consumable. Browse alternatives in the PAPR filters collection.

When should I replace the CleanSpace WORK HEPA filter?

Replace it when the CleanSpace unit indicates end of life, or per your facility's documented schedule — whichever comes first. Heavy dust loading shortens filter life, so abrasive work may require more frequent swaps. Follow a respirator cartridge change-out schedule and log replacements in your program.

Do I need to use genuine CleanSpace filters, or will a third-party filter work?

Use genuine OEM filters only. The CleanSpace WORK Kit's NIOSH approval is granted as a complete certified assembly, and substituting non-approved media voids that approval. That makes an off-brand filter both a protection risk and an OSHA 1910.134 compliance problem — see NIOSH 42 CFR Part 84 certification.

Does this filter come with a prefilter?

No, the CS3022WORK 3-pack contains HEPA filters only and no prefilter. In dusty or abrasive work that means the HEPA media takes the full dust load and can clog faster, so plan your change-out cadence accordingly. Some other platforms, like 3M Versaflo, offer a disposable prefilter to extend HEPA life.

What hazards is this filter appropriate for?

It is appropriate for particulate hazards — dust, mists and fumes from tasks like grinding, sanding, remediation and general fabrication. Confirm via air monitoring that your exposure is particulate-only before relying on it, and use a respirator cartridge label to verify what each consumable is rated for.

How does this compare to a 3M Versaflo HE filter?

Both are HE/HEPA-class particulate filters, but they fit entirely different systems. The CS3022WORK fits the CleanSpace WORK Kit, while 3M's TR-3712N fits the TR-300 series and the TR-6710N fits the TR-600/800 series. They are not cross-compatible — choose the filter that matches the blower you already own.

Can I use this filter for asbestos, lead or mold abatement?

As a 99.97% HEPA-class particulate filter it captures the particulate fraction of those hazards, but abatement work is heavily regulated and must follow your written program and the applicable OSHA standards. Verify the assigned protection factor of your CleanSpace WORK assembly against the exposure, and consult when OSHA requires a respirator and your written respiratory protection program.

Does using a PAPR filter mean I still need a fit test?

It depends on the headtop, not the filter. The CleanSpace WORK Kit uses a half mask that seals to the face, so it requires a fit test like other tight-fitting respirators — unlike loose-fitting PAPR hoods. The filter itself doesn't change that requirement; see what happens if a respirator doesn't fit.

How long do CleanSpace WORK filters last on the shelf?

Particulate filters have a defined shelf life and should be rotated stock-first so a 3-pack bought ahead doesn't age out before use. Store them sealed, cool and dry per the manufacturer's guidance and your maintenance, inspection and storage procedures. Our cartridge shelf life reference explains why this matters.

Is the CleanSpace WORK a PAPR, and how does the filter relate to that?

Yes — the CleanSpace WORK Kit is a NIOSH-approved powered air-purifying respirator where a blower pushes air through this filter so you aren't relying on lung power. The filter is the air-cleaning element of that system; without it there is no respiratory protection. Read what a PAPR is for the full picture.

What's the difference between this filter and a PAPR cartridge?

A filter like the CS3022WORK removes particulates only, while a cartridge contains sorbent media to capture specific gases or vapors (often combined with a particulate layer). They are not interchangeable, and the right choice is dictated by your hazard. Compare options in the PAPR cartridges collection and read how to choose a respirator cartridge.

Where does this filter fit in choosing a complete PAPR program?

The filter is a downstream consumable decision — first choose the system and headtop that match your hazard and tasks, then standardize on the matching genuine media. If you're still selecting a system, start with the best PAPR systems guide and the powered respirators collection, then lock in the consumable, in this case the CleanSpace WORK HEPA filter.

Can I stretch filter life by cleaning or reusing it?

No — HEPA particulate filters are not cleanable and must not be washed, blown out or reused past their service limit; doing so degrades media and can compromise protection. Replace at the unit's end-of-life indication or your scheduled interval, and document it per your respirator maintenance and inspection procedures.

Does this filter affect the respirator's assigned protection factor (APF)?

The APF is a property of the certified respirator assembly and its headtop, not the particulate filter alone — provided you use the genuine CS3022WORK that keeps the NIOSH approval intact. Substituting non-approved media invalidates the approval and therefore the APF basis. Confirm the APF for your specific CleanSpace WORK configuration against your hazard exposure.
