What the Product Page Documents

Published July 16, 2026 · Last updated July 27, 2026

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. Everything below measures the product against that role: its honest limits, its true alternatives, and where the linked guides rank it.

Honest Limits

Honest limits: this is negative-pressure, air-purifying protection — it needs a fit-tested seal, the right cartridge or filter for the named hazard, and a change schedule built on service-life data per OSHA 1910.134. Escape, IDLH, and unknown atmospheres are outside its lane entirely.

Why trust WC Safety

WC Safety is an independent, affiliate-supported review site. It is not a retailer: it holds no inventory, takes no orders, and earns only from qualifying purchases through clearly marked links — which never changes what a product is rated to do. Standards language is taken from the regulation text directly, and ratings are reported as the manufacturer publishes them. We run no laboratory and perform no testing of our own. Where published sources disagree, we say so and plan on the conservative figure rather than the flattering one.

Our methodology

Figures come from the regulation and the published specification, in that order. Derated numbers are calculated, not estimated. Nothing here is presented as a measured result, because we measure nothing.
