GVS Elipse SPR474 OV/AG/P100 Replacement Filters – Organic Vapor, Acid Gas & P100 Dust Filter Pair

NIOSH Tri-Class Protection — Organic Vapor, Acid Gas, and P100 Particulate in a Single Bayonet Filter

The GVS Elipse SPR474 OV/AG/P100 Replacement Filter delivers simultaneous protection against organic vapors, acid gases, and airborne particulates at the P100 filtration level — all in a single low-profile bayonet-mount filter pair. NIOSH-certified under 42 CFR Part 84, Approval Number 84A-8078, the SPR474 is designed for workers in multi-hazard environments where particulate exposure coexists with organic solvent vapors and acid gas hazards. It is the replacement filter for GVS Elipse half masks SPR472 (S/M) and SPR473 (M/L), and the Integra SPR555 (S/M) and SPR556 (M/L) platforms. The SPR474 replaces the pre-installed cartridges included with GVS Elipse OV/AG/P100 respirator kits.

The filter cartridge integrates three protection layers in sequence: an outer HESPA P100 particulate filter that captures aerosolized particles before they reach the adsorbent bed, an acid gas adsorbent layer for chlorine, hydrogen chloride, sulfur dioxide, and hydrogen fluoride, and an optimized activated carbon bed for organic vapor capture. GVS engineers the activated carbon with specific pore size, grain size, activity level, and density parameters that together balance organic vapor adsorption capacity — rated up to 5,000 ppm total organic vapor capacity — against breathing resistance. The P100 filter component is rated at 99.95% minimum efficiency at 0.3 microns for both oil and non-oil aerosols.

Compliance and Certification

The SPR474 holds active NIOSH certification under 42 CFR Part 84, Approval Number 84A-8078. The certification covers the combined filter assembly: OV/AG/P100 combination protection tested to NIOSH standards. This is the same approval number as the GVS Elipse OV/AG/P100 half mask kits (SPR472/SPR473), confirming the replacement filter delivers identical certified performance to the factory-installed cartridges. OSHA 29 CFR 1910.134 requires that air-purifying respirator cartridges be NIOSH-approved for the specific hazard present — the SPR474 satisfies this requirement for environments with simultaneous OV, acid gas, and particulate hazards.

Performance Assessment

The SPR474 performs well as a combination filter in applications with moderate to high particulate loads accompanied by organic vapor or acid gas exposure. The outer P100 pre-filter protects the adsorbent bed from particulate clogging, extending adsorbent service life in dusty environments compared to cartridges without an integrated pre-filter. Breathing resistance is higher than a particulate-only filter due to the combined bed depth; this is characteristic of all OV/AG/P100 combination cartridges and is not unique to the GVS design.

Organic vapor breakthrough will eventually occur before the P100 filter is exhausted — organic vapor cartridges do not include an end-of-service indicator, and a NIOSH-compliant change schedule or real-time monitoring is required. The P100 filter element continues to protect against particulates after OV breakthrough; however, a combined cartridge where the adsorbent has reached breakthrough should be replaced entirely.

Strengths

• NIOSH OV/AG/P100 certification under 84A-8078 — tri-class protection in a single cartridge assembly without multiple filter stages
• Integrated P100 outer filter protects the adsorbent bed from particulate loading, extending OV capacity in dusty environments
• Low-profile bayonet design maintains the compact geometry of the GVS Elipse and Integra platform
• Up to 5,000 ppm rated organic vapor capacity with optimized activated carbon parameters
• Up to 5-year shelf life in sealed original packaging

Limitations

• No end-of-service indicator — organic vapor breakthrough requires a documented change schedule per OSHA 29 CFR 1910.134 App B or real-time vapor monitoring; do not rely on odor detection alone
• Not rated for IDLH-level atmospheres, mercury vapor, formaldehyde, or ammonia — check the NIOSH approval for the specific vapor hazards present before selection
• Higher breathing resistance than particulate-only filters; workers with respiratory conditions should confirm medical clearance for tight-fitting respirators under 29 CFR 1910.134 requirements

Recommended Use Cases

The SPR474 is appropriate for automotive refinishing and spray painting with solvent-based coatings, solvent-based epoxy and polyurethane application with simultaneous overspray particulate, chemical laboratory work with acid gas and organic vapor co-exposure, industrial cleaning with acid and solvent products in dusty environments, and painting and coating operations under OSHA's spray finishing standard (29 CFR 1910.94). Confirm acid gas coverage — the SPR474 is rated for chlorine, hydrogen chloride, and sulfur dioxide at concentrations below IDLH; for specific acid gas hazards, verify against the NIOSH approval documentation.

Verdict and Alternatives

The SPR474 is the correct replacement filter for GVS Elipse OV/AG/P100 respirator kits and delivers full certified tri-class protection consistent with the original factory cartridges. Workers needing OV/P100 without acid gas coverage (lower cost, lower breathing resistance) can use the SPR658. Workers on non-GVS platforms should consider 3M 60923 (OV/AG/P100) for 3M 6000-series respirators or Honeywell North 75SCP100L for North half masks.

Frequently Asked Questions

What is the NIOSH certification for the SPR474?

The SPR474 holds NIOSH approval under 42 CFR Part 84, Approval Number 84A-8078, for OV/AG/P100 combination protection. This is the same approval number as the GVS Elipse OV/AG/P100 half mask respirator kits — the replacement filter delivers identical certified performance to the factory-installed cartridges.

Which GVS masks use the SPR474 filters?

The SPR474 is the replacement filter for GVS Elipse OV/AG/P100 masks (SPR472 S/M and SPR473 M/L) and GVS Integra OV/AG/P100 masks (SPR555 S/M and SPR556 M/L). Any GVS half mask with the standard GVS bayonet interface that was originally equipped with OV/AG/P100 combination cartridges should use the SPR474 for replacement.

How do I establish a cartridge change schedule for the SPR474?

OSHA requires a documented change schedule per 29 CFR 1910.134 App B for all organic vapor cartridges without end-of-service indicators. The change schedule may be based on cartridge manufacturer service life data, OSHA's Safety and Health Topics calculation method, industrial hygiene sampling results, or a real-time vapor monitoring program. Do not rely on odor detection — by the time vapor is detectable, breakthrough has already occurred for many hazardous substances.

Does the SPR474 protect against formaldehyde or ammonia?

No. The SPR474 OV/AG rating covers organic vapors and specific acid gases (chlorine, hydrogen chloride, sulfur dioxide, hydrogen fluoride). Formaldehyde, ammonia, and mercury vapor require specialty adsorbent media not present in the SPR474. Consult GVS's filter selection guide or a Certified Industrial Hygienist to identify the correct filter for formaldehyde or ammonia applications.

Can the SPR474 be used for lead paint renovation or abatement work?

Yes, for the particulate component. The P100 filtration rating meets EPA RRP and OSHA lead standard (29 CFR 1910.1025) requirements for respiratory protection during lead paint disturbance. If the renovation also involves solvent-based strippers or coating products with OV and/or acid gas hazards, the SPR474's combination protection is appropriate. For pure lead particulate applications without solvent hazards, the lower-cost SPR321 P100 particulate-only filter is the more economical selection.
