The GVS Elipse SPR321 P100 Replacement Filters – NIOSH Dust Filter Pair for Elipse & Integra Half Masks is a respirator filter from GVS, stocked at $15.28. This review restates what the product page documents, places it in its respiratory protection lane, and points to the ranked guides for the head-to-head field.

What the Product Page Documents

The GVS Elipse SPR321 P100 Replacement Filter is the standard-replacement particulate filter for GVS Elipse and Integra half mask respirators in environments with dust, stone dust, metal fumes, and non-oil aerosol hazards. NIOSH-certified under 42 CFR Part 84, Approval Number TC-84A-6949, the SPR321 filters provide a minimum 99.95% filtration efficiency at the P100 classification — the highest NIOSH particulate filtration rating. Sold as a matched pair (one filter per side), the SPR321 replaces the factory-installed filters on the Elipse SPR451, SPR457, SPR449, and SPR456 half masks, as well as the Integra SPR549, SPR550, SPR551, and SPR552 platforms.

The filter assembly uses GVS's HESPA (High Efficiency Synthetic Particulate Airfilter) media, a layered synthetic filter substrate that delivers P100 efficiency at reduced breathing resistance relative to conventional fiber-based P100 filters. The bayonet-mount attachment design — common across GVS's Elipse and Integra product families — allows tool-free filter replacement in under ten seconds without disturbing the facepiece seal or head strap adjustment. GVS rates the SPR321 for up to five years from the date of manufacture when stored sealed in original packaging.

The SPR321 holds active NIOSH certification under 42 CFR Part 84, Approval Number TC-84A-6949. NIOSH certification requires independent third-party laboratory testing of filtration efficiency, inhalation resistance, exhalation resistance, and filter integrity — it is not a manufacturer self-declaration. The P100 classification covers oil and non-oil based aerosols, distinguishing it from N-class and R-class filters, which are rated only for non-oil and limited-oil-resistance applications, respectively. Current approval status is verifiable on the NIOSH Certified Equipment List maintained at cdc.gov/niosh/npptl.

Where It Earns Its Slot

Where it earns its slot: The GVS Elipse SPR321 P100 Replacement Filter is the standard-replacement particulate filter for GVS Elipse and Integra half mask respirators in environments with dust, stone dust, metal fumes, and non-oil aerosol hazard… The product page carries the full documented configuration; this review deliberately restates rather than embellishes it — claims beyond the listing don't appear here.

Honest Limits

Its honest limits: like every respiratory protection product, it protects within its stated ratings and use lane only — the family FAQ below draws those boundaries, and the guides linked underneath rank it against its true alternatives. Where the listing is silent on a spec, so are we; verify markings and instructions on arrival.

Pros and Cons

Frequently Asked Questions

How much does the GVS Elipse SPR321 P100 Replacement Filters – NIOSH Dust Filt cost?

$15.28 at the linked listing — prices track the live page, and configuration choices there can shift the number.

What does the GVS Elipse SPR321 P100 Replacement Filters – NIOSH Dust Filt listing actually document?

The GVS Elipse SPR321 P100 Replacement Filter is the standard-replacement particulate filter for GVS Elipse and Integra half mask respirators in environments with dust, stone dust, metal fumes, and non-oil aerosol hazards. NIOSH-certified under 42 CFR Part 84, Approval Number TC-84A-6949, the SPR321…

What are the alternatives to the GVS Elipse SPR321 P100 Replacement Filters – NIOSH Dust Filt?

The sibling respirator filter options linked in this review, ranked head-to-head in the respiratory protection guides below — start with the buyer's guides for the field view.

What do N95, P100, and the letter/number classes mean?

The letter is oil resistance (N=not, R=resistant, P=oil-proof); the number is filtration efficiency (95/99/100 ≈ 95%/99%/99.97%). The class on the listing is the class — higher isn't always better if breathing resistance parks the mask on the chin.

When does OSHA require fit testing for this equipment?

Any employer-required tight-fitting respirator — N95s included — needs fit testing before use and annually per 1910.134, plus user seal checks every wearing. Loose-fitting PAPRs are the exception.

How long do cartridges and filters last?

Chemical cartridges follow a change schedule (or end-of-service indicators) — odor breakthrough is a failure, not a signal. Particulate filters last until breathing resistance rises or damage/loading shows. The employer's change schedule is a 1910.134 requirement.

Can I pair any cartridge with any facepiece?

No — attachment systems are proprietary (bayonet counts and geometries differ by brand and series). Reviews here restate the compatibility each listing claims; the manufacturer's matrix governs.

What does a respirator NOT protect against?

Air-purifying respirators don't supply oxygen — oxygen-deficient atmospheres and IDLH conditions require supplied air. And a cartridge only stops what its class covers; the SDS names the contaminant to match.

Why does facial hair matter?

Anything between skin and seal defeats tight-fitting respirators — it fails fit tests and the standard. The options are shaving policy or loose-fitting PAPRs; there is no third answer.

How should respirators be cleaned and stored?

Per 1910.134 Appendix B-2: cleaned and sanitized (alcohol-free wipes between uses, periodic washing), stored away from contamination, sunlight, and distortion. Filters stay sealed until service.

What's the difference between a half mask and full face for the same cartridge?

Assigned protection factor (10 vs 50 for full face) and eye protection — the same cartridge protects longer lungs-wise on a full face because leakage is lower. Exposure levels pick the facepiece.

Are exhalation valves allowed?

For most industrial use, yes — valves ease breathing without lowering protection for the wearer. Sterile fields and source-control settings restrict them; that's a policy question, not a NIOSH one.

What is an assigned protection factor (APF)?

The exposure multiplier a respirator class is credited with under 1910.134 — half masks 10, full face 50, PAPR hoods 25-1000 by type. Exposure over PEL×APF means stepping up the class.

PAPR vs negative-pressure — when to step up?

Comfort over long shifts, beards, high exposures, and heat all point to PAPRs — blown air instead of pulled. The cost gap narrows once cartridge consumption and compliance are priced in.

Do respirators expire?

Filters and cartridges carry shelf lives sealed; facepiece elastomers age with use and cleaning chemistry. Date-check stock, rotate it, and let the fit test catch what inspection misses.

The Bottom Line

Rated 4.5/5 on documented spec, configuration, and value. The GVS Elipse SPR321 P100 Replacement Filters – NIOSH Dust Filter Pair fo does the job its listing describes — the guides above tell you whether it's the right pick against the field.

How We Review

Respiratory reviews restate NIOSH approvals, filter classes, and compatibility exactly as listed — cartridge pairings follow the manufacturer's attachment rules (retainers where required, direct-attach where designed), and every tight-fitting respirator assumes the annual fit test our kits collection now sells. Ratings reflect documented spec, configuration, and value — the basis is stated, not invented testing.
