GVS Elipse SPR321 P100 Replacement Filters – NIOSH Dust Filter Pair for Elipse & Integra Half Masks

NIOSH P100 Particulate Filtration for GVS Elipse and Integra Half Mask Respirators

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.

Compliance and Certification

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.

Performance Assessment

The SPR321 performs to P100 specification across the range of conditions for which it is designed: dry and wet particulate environments, metal fume, mineral dust, combustion particles, and biological aerosols. Breathing resistance is measured below the NIOSH inhalation resistance threshold for P100 filters — users in sedentary to moderate-exertion jobs typically report acceptable airflow. Filter loading in high-dust environments (active grinding, sandblasting, demolition) will increase resistance over time; replacement is indicated when inhalation effort increases noticeably during use.

The bayonet attachment interface is consistent across all current GVS Elipse and Integra half masks, meaning the SPR321 does not require compatibility verification by mask model — any Elipse or Integra half mask that accepts GVS bayonet cartridges will accept the SPR321. This standardization simplifies procurement for facilities managing multiple mask sizes.

Strengths

• NIOSH P100 certification under TC-84A-6949 — independently tested, not self-declared
• Compatible across the full GVS Elipse (SPR451, SPR457, SPR449, SPR456) and Integra (SPR549–SPR552) half mask range
• HESPA filter media achieves P100 efficiency at reduced breathing resistance versus conventional fiber media
• Tool-free bayonet replacement in under ten seconds — no facepiece disassembly required
• Up to 5-year shelf life in sealed packaging — supports bulk procurement programs

Limitations

• Particulate-only protection — provides zero protection against organic vapors, acid gases, ammonia, or any gaseous hazard. Environments with simultaneous vapor and dust exposure require a combination filter (SPR474 OV/AG/P100 or SPR658 OV/P100)
• Filter loading rate varies significantly with dust concentration — high-production environments may require daily filter replacement; replacement frequency planning should be based on site-specific exposure assessment
• Not compatible with GVS full-facepiece or PAPR platforms that use separate filter mounting systems

Recommended Use Cases

The SPR321 is appropriate for operations involving silica-generating tasks (concrete cutting, masonry tuck-pointing, stone fabrication), metal fume exposure during welding and grinding, mineral dust in mining and quarrying environments, wood dust in furniture manufacturing and cabinetry, and particulate exposure during construction demolition and renovation. OSHA's silica standard (29 CFR 1910.1053 / 1926.1153) and lead standard (29 CFR 1910.1025) identify P100 as the required protection class for high-exposure operations — the SPR321 meets those requirements when used with a properly fitted GVS Elipse or Integra half mask.

Verdict and Alternatives

The GVS SPR321 is a reliable, cost-effective P100 replacement filter for facilities already equipped with GVS Elipse or Integra respirators. For multi-hazard environments requiring both particulate and vapor protection, the SPR474 (OV/AG/P100) or SPR658 (OV/P100) are the appropriate upgrades within the same bayonet system. Users seeking P100 filtration on non-GVS platforms should consider 3M 2091 filters for 3M 6000-series respirators or Honeywell North 75SCP100L for North half masks.

Frequently Asked Questions

Which GVS half masks are compatible with the SPR321 filters?

The SPR321 is compatible with all GVS Elipse half mask models (SPR451 S/M, SPR457 M/L, SPR449 S/M, SPR456 M/L) and all GVS Integra half mask models (SPR549 S/M, SPR550 M/L, SPR551 S/M, SPR552 M/L). Any GVS Elipse or Integra half mask using the standard GVS bayonet cartridge interface accepts the SPR321.

Does the SPR321 filter protect against organic vapors or gases?

No. The SPR321 is a pure particulate filter — it contains no activated carbon or chemical adsorbent media and provides no protection against organic vapors, acid gases, ammonia, or other gaseous hazards. For environments requiring both particulate and vapor protection, use the GVS SPR658 (OV/P100) or SPR474 (OV/AG/P100) combination filters.

What is the NIOSH approval number for the SPR321?

The SPR321 holds NIOSH approval under TC-84A-6949, certified to 42 CFR Part 84 for P100 particulate filtration. Current certification status is publicly verifiable on the NIOSH Certified Equipment List at cdc.gov/niosh/npptl.

How often should the SPR321 filters be replaced?

GVS rates the SPR321 for up to five years from the manufacture date when stored sealed. In service, replace when breathing resistance increases noticeably during use, when the filter sustains physical damage, or when contaminated with liquids. In heavy-dust environments such as concrete grinding or sandblasting, daily replacement is standard practice under typical respiratory protection programs.

Can the SPR321 be used for silica exposure under OSHA's silica standard?

Yes. OSHA's silica rule (29 CFR 1910.1053 for general industry, 29 CFR 1926.1153 for construction) requires P100 respiratory protection for high-exposure silica tasks. The SPR321, when used with a properly fitted GVS Elipse or Integra half mask that has passed quantitative or qualitative fit testing, meets the P100 requirement of the silica standard.
