GVS Elipse SPR658 OV/P100 Replacement Filters – Organic Vapor & P100 Dust Filter Pair

NIOSH OV/P100 Combination Filter — Organic Vapor and P100 Particulate Protection for GVS Integra & Elipse Half Masks

The GVS Elipse SPR658 OV/P100 Replacement Filter provides dual-class NIOSH-certified protection against organic vapors and P100-rated particulates in a single low-profile bayonet cartridge pair. Certified under 42 CFR Part 84, Approval Number TC-84A-3538, the SPR658 serves workers in environments with both airborne dust and organic vapor hazards where acid gas protection is not required — including spray painting, solvent-based coating application, and woodworking with finishing products. The SPR658 is the replacement filter for GVS Elipse half masks SPR656 (S/M) and SPR657 (M/L), and GVS Integra masks SPR659 (S/M) and SPR660 (M/L).

GVS engineered the SPR658 around the same HESPA particulate filter media used in the SPR321 P100-only filter, integrating an organic vapor activated carbon adsorbent bed with a rated capacity of up to 5,000 ppm total organic vapor concentration. The P100 outer filter acts as a pre-filter that prevents dust from entering the carbon bed, extending the adsorbent's service life in particulate-laden environments. The combined filter achieves 99.95% or higher efficiency at 0.3 microns for the P100 particulate component across both oil and non-oil aerosols.

Compliance and Certification

The SPR658 holds active NIOSH certification under 42 CFR Part 84, Approval Number TC-84A-3538, for OV/P100 combination protection. This certification covers the assembled filter — the particulate and vapor protection components are tested as a unit under NIOSH's 42 CFR Part 84 testing protocol. Under OSHA 29 CFR 1910.134, the SPR658 satisfies the requirement for NIOSH-approved air-purifying respirator protection in environments with simultaneous organic vapor and particulate hazards, provided concentrations remain below IDLH levels and the respirator is used within a written respiratory protection program.

Performance Assessment

The SPR658 performs effectively in the OV/P100 application range: environments with measured organic vapor concentrations below occupational exposure limits where a full acid gas component is not warranted. The filter maintains the low-profile geometry characteristic of the GVS Elipse cartridge family, imposing less face and jaw weight than larger combination cartridges from competing platforms. Breathing resistance is moderate — higher than a P100-only filter but acceptable for sustained work at moderate exertion levels.

Workers should note that the SPR658 does not include an end-of-service indicator for the organic vapor component. Odor breakthrough may occur at some hazardous concentrations before the wearer detects it — a documented cartridge change schedule per OSHA 29 CFR 1910.134 App B is required. The P100 filter element will typically outlast the carbon adsorbent in moderate-OV environments; when the carbon is saturated, the entire cartridge pair should be replaced even if particulate resistance has not increased significantly.

Strengths

• NIOSH OV/P100 certification under TC-84A-3538 — documented dual-class protection for regulatory compliance in OV/particulate environments
• Integrated P100 pre-filter shields the carbon bed from particulate loading, extending OV adsorption capacity in dusty environments
• Up to 5,000 ppm organic vapor capacity with optimized carbon parameters
• Maintains GVS Elipse/Integra bayonet compatibility — tool-free replacement with any compatible GVS half mask
• Lower cost than OV/AG/P100 (SPR474) where acid gas protection is not required

Limitations

• No acid gas protection — the SPR658 does not adsorb chlorine, hydrogen chloride, sulfur dioxide, or other acid gases. Environments with acid gas co-exposure require the SPR474 (OV/AG/P100)
• No end-of-service indicator — organic vapor change schedule must be documented per 29 CFR 1910.134 App B or industrial hygiene monitoring
• Not compatible with GVS Elipse or Integra masks originally equipped with SPR474 OV/AG/P100 cartridges — confirm replacement filter matches the mask model's original certification

Recommended Use Cases

The SPR658 is appropriate for automotive refinishing and spray painting with lacquer and enamel products not containing acid catalysts, woodworking finishing operations with solvent-based stains and varnishes, solvent cleaning operations in dusty environments, painting contractor work with oil-based paints and primers, and industrial assembly with adhesive products containing organic solvents. Verify that acid gases are not present before selecting the SPR658 over the SPR474 — paint products containing isocyanate hardeners or acid-catalyst clearcoats require acid gas coverage.

Verdict and Alternatives

The GVS SPR658 is the appropriate OV/P100 replacement filter for GVS Elipse and Integra half masks specified for organic vapor and particulate environments without acid gas hazards. Workers in environments with additional acid gas exposures should upgrade to the SPR474 OV/AG/P100. The 3M 60921 (OV/P100) provides comparable protection on 3M 6000-series respirators; the Honeywell North 75SCP100L is the equivalent for North half mask platforms.

Frequently Asked Questions

What is the NIOSH approval number for the SPR658?

The SPR658 holds NIOSH certification under 42 CFR Part 84, Approval Number TC-84A-3538, for OV/P100 combination protection. Current approval status is verifiable on the NIOSH Certified Equipment List at cdc.gov/niosh/npptl.

What is the difference between the SPR658 and SPR474?

Both are NIOSH-certified combination filters for GVS Elipse/Integra half masks, but they cover different hazard classes. The SPR658 (OV/P100, TC-84A-3538) protects against organic vapors and P100 particulates. The SPR474 (OV/AG/P100, 84A-8078) adds acid gas protection (chlorine, hydrogen chloride, sulfur dioxide, hydrogen fluoride). Select SPR474 when acid gases are present alongside organic vapor and particulate hazards; use SPR658 when only organic vapors and particulates are present.

Which GVS half masks use the SPR658 replacement filter?

The SPR658 is the replacement filter for GVS Elipse OV/P100 half masks (SPR656 S/M, SPR657 M/L) and GVS Integra OV/P100 half masks (SPR659 S/M, SPR660 M/L). Do not substitute SPR658 for SPR474 on masks originally certified with OV/AG/P100 protection without reviewing the site's hazard assessment for acid gas exposure.

How do I know when to change the SPR658 cartridges?

The SPR658 does not include an end-of-service indicator. Cartridge change scheduling must be based on a documented method per OSHA 29 CFR 1910.134 App B — either using GVS service life data and measured vapor concentrations, a conservative fixed change schedule, or real-time vapor monitoring. Replace when odor breakthrough is detected, but do not rely on odor as the primary change-schedule method since breakthrough may occur before odor is perceptible for some hazardous substances.

Is the SPR658 appropriate for spray painting with two-component urethane paints?

Two-component urethane systems contain isocyanate hardeners — one of the most sensitizing respiratory hazards in occupational settings. NIOSH and OSHA guidance on isocyanate exposure recommends supplied-air respiratory protection at higher concentrations. At lower, well-controlled concentrations below the isocyanate ceiling limit, an OV/P100 cartridge may be used following a written respiratory protection program and industrial hygiene assessment. Consult a Certified Industrial Hygienist (CIH) before selecting air-purifying protection for two-component urethane applications.
