NIOSH-certified under Standard 84A-8078, the Elipse is the appropriate choice for painters, auto body technicians, chemical handlers, and industrial workers who operate in environments where multiple airborne hazards are present concurrently. The mask ships with one pair of pre-installed OV\/AG\/P100 combination cartridges, enabling immediate use without a separate cartridge purchase.\u003c\/p\u003e\n\n\u003cp\u003eGVS designed the Elipse around a tri-fold silicone face seal that compresses flat for storage and tool-belt carry, then expands to a fully contoured seal during use. The silicone construction — rather than thermoplastic rubber — conforms to a wider range of facial geometries, reducing pressure points during extended wear. At approximately 100 grams, the Elipse is among the lightest half masks in its protection class, a measurable advantage for workers performing overhead tasks or wearing the mask for consecutive hours.\u003c\/p\u003e\n\n\u003ch2\u003eCompliance and Certification\u003c\/h2\u003e\n\n\u003cp\u003eThe Elipse OV\/AG\/P100 holds active NIOSH certification under 42 CFR Part 84, Approval Number 84A-8078. This certification covers the combined cartridge assembly: organic vapor adsorbent, acid gas adsorbent, and P100 particulate filter rated at 99.97% minimum efficiency against oil and non-oil aerosols. NIOSH certification is not manufacturer self-declaration — it requires independent third-party laboratory testing of breakthrough capacity, filtration efficiency, inhalation and exhalation resistance, and facepiece integrity.\u003c\/p\u003e\n\n\u003cp\u003eThe P100 designation satisfies OSHA respiratory protection requirements (29 CFR 1910.134) for operations involving hazardous particulates that also carry vapor or gas hazards, including certain paint spraying applications under 29 CFR 1910.94 and chemical handling tasks defined in individual OSHA substance-specific standards.

The silicone face seal maintains a reliable perimeter seal across mid-range facial widths and accepts standard GVS bayonet cartridges without tools. The adjustable three-point head strap distributes weight evenly and reduces downward pull during overhead work. The included cartridges are rated for organic vapors and acid gases at standard industrial concentrations below the IDLH threshold — the mask is not rated for emergency response or IDLH-level exposures, which require supplied-air or SCBA equipment.\u003c\/p\u003e\n\n\u003cp\u003eBreathing resistance at rest is lower than most elastomeric half masks in its class, attributed in part to the low-profile cartridge geometry that reduces dead space.

Workers requiring eye protection integration should evaluate the GVS Elipse P3 with full-face shield accessory or 3M 6000 Series with Secure-Click filter technology.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3\u003eWhat does OV\/AG\/P100 protection cover?\u003c\/h3\u003e\n\u003cp\u003eOV designates organic vapor adsorbent protection — the cartridge contains activated carbon that captures solvent vapors including toluene, xylene, and acetone. AG designates acid gas protection, covering chlorine, hydrogen chloride, hydrogen fluoride, and sulfur dioxide at concentrations below the IDLH threshold. P100 designates the highest NIOSH particulate filtration class: 99.97% minimum efficiency against both oil and non-oil aerosols. The combination cartridge provides simultaneous protection against all three hazard categories in a single assembly.\u003c\/p\u003e\n\n\u003ch3\u003eIs the GVS Elipse NIOSH certified?\u003c\/h3\u003e\n\u003cp\u003eYes. The Elipse OV\/AG\/P100 holds active NIOSH certification under 42 CFR Part 84, Approval Number 84A-8078. NIOSH certification requires independent laboratory testing — it is not a manufacturer self-declaration. Current approval status is verifiable on the NIOSH Certified Equipment List maintained at cdc.gov\/niosh\/npptl.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I choose between S\/M and M\/L sizes?\u003c\/h3\u003e\n\u003cp\u003eGVS publishes a fit guide at gvs.com based on facial measurements. As a general reference, S\/M fits most female facial dimensions and smaller male users with narrower or shorter facial width; M\/L fits the majority of average to large male users. For OSHA-compliant respirator programs, quantitative or qualitative fit testing is required regardless of size selection — self-assessment of fit is not an acceptable substitute under 29 CFR 1910.134.\u003c\/p\u003e\n\n\u003ch3\u003eWhat replacement cartridges does the Elipse use?\u003c\/h3\u003e\n\u003cp\u003eThe Elipse OV\/AG\/P100 uses GVS SPR503 combination cartridges (organic vapor, acid gas, P100). The cartridges attach via the GVS standard bayonet mount. Replace cartridges when organic vapor breakthrough odor is detected, at the end of the service life determined by your respiratory protection program, or when breathing resistance increases significantly due to P100 filter loading. GVS recommends cartridge replacement at least every 6 months regardless of use frequency.\u003c\/p\u003e\n\n\u003ch3\u003eCan the GVS Elipse be used for spray painting?\u003c\/h3\u003e\n\u003cp\u003eYes. The OV\/AG\/P100 protection class is appropriate for spray painting applications involving solvent-based paints, lacquers, and enamels in environments where both organic vapors and particulate overspray are present. OSHA 29 CFR 1910.94 regulates spray finishing operations — a written respiratory protection program, fit testing, and medical evaluation are required before an employee uses any tight-fitting respirator, including the Elipse, in covered spray painting applications.\u003c\/p\u003e\n\n\u003ch3\u003eIs the Elipse compatible with safety eyewear or face shields?\u003c\/h3\u003e\n\u003cp\u003eThe Elipse half mask is compatible with most standard safety eyewear and face shields when the head strap is adjusted to avoid interference. GVS also offers an Elipse full-face shield accessory (SPR490) that attaches to the mask body, providing integrated eye and face protection.

NIOSH-certified under 42 CFR Part 84, this respirator suits workers in paint spraying, solvent handling, chemical processing, and industrial environments where simultaneous vapor and particulate hazards require a single integrated solution. The SPR113J (S\/M) and SPR123J (M\/L) models ship with GVS's low-profile bayonet cartridges and a soft silicone face seal designed for extended wear.\u003c\/p\u003e\n\n\u003cp\u003eGVS engineered the Elipse series around the proposition that a half mask respirator can be light enough to be worn without fatiguing the user over a full shift. The silicone facepiece folds flat for pocket or tool-belt storage, and the three-point head strap reduces the mask's tendency to slide during overhead or dynamic work tasks. The result is a respirator that workers are more likely to keep on rather than remove during brief interruptions — a behavioral factor that directly affects real-world protection outcomes.\u003c\/p\u003e\n\n\u003ch2\u003eCompliance and Certification\u003c\/h2\u003e\n\n\u003cp\u003eThe GVS Elipse OVAG P100 holds active NIOSH approval under 42 CFR Part 84.

Size selection should be based on GVS's published fit guide and confirmed via OSHA-required fit testing. S\/M generally suits smaller facial geometries including most female users; M\/L suits average to larger male users. Both sizes use the same OVAG P100 cartridges and provide identical NIOSH-certified protection.\u003c\/p\u003e\n\n\u003ch3\u003eHow often must the cartridges be replaced?\u003c\/h3\u003e\n\u003cp\u003eOrganic vapor cartridges do not include a visual end-of-service indicator. Replacement is required when organic vapor breakthrough odor is detected, at the end of a calculated service life per OSHA 29 CFR 1910.134 App B, or on a documented fixed change schedule. The P100 filter layer requires replacement when breathing resistance increases noticeably or the filter is physically damaged. In high-dust environments, more frequent replacement of the P100 element is standard.\u003c\/p\u003e\n\n\u003ch3\u003eIs the GVS Elipse appropriate for spray painting with isocyanate-based paints?\u003c\/h3\u003e\n\u003cp\u003eIsocyanate-based paints (polyurethane, two-component coatings) present both particulate and reactive isocyanate vapor hazards. OSHA and NIOSH guidance indicates that supplied-air respirators may be required at higher exposure concentrations for isocyanate applications. A Certified Industrial Hygienist (CIH) or Certified Safety Professional (CSP) should assess isocyanate exposure levels before selecting an air-purifying respirator. The Elipse OVAG P100 may be appropriate for low-concentration isocyanate applications below defined thresholds, but this determination requires professional industrial hygiene evaluation.\u003c\/p\u003e\n\n\u003ch3\u003eCan the Elipse mask be used with a beard or significant facial hair?\u003c\/h3\u003e\n\u003cp\u003eNo tight-fitting half mask — including the GVS Elipse — can achieve the face seal required for OSHA compliance when the user has beard growth along the face seal contact path.

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.\u003c\/p\u003e\n\n\u003ch2\u003eStrengths\u003c\/h2\u003e\n\n\u003cul\u003e\n  \u003cli\u003eNIOSH OV\/P100 certification under TC-84A-3538 — documented dual-class protection for regulatory compliance in OV\/particulate environments\u003c\/li\u003e\n  \u003cli\u003eIntegrated P100 pre-filter shields the carbon bed from particulate loading, extending OV adsorption capacity in dusty environments\u003c\/li\u003e\n  \u003cli\u003eUp to 5,000 ppm organic vapor capacity with optimized carbon parameters\u003c\/li\u003e\n  \u003cli\u003eMaintains GVS Elipse\/Integra bayonet compatibility — tool-free replacement with any compatible GVS half mask\u003c\/li\u003e\n  \u003cli\u003eLower cost than OV\/AG\/P100 (SPR474) where acid gas protection is not required\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eLimitations\u003c\/h2\u003e\n\n\u003cul\u003e\n  \u003cli\u003eNo acid gas protection — the SPR658 does not adsorb chlorine, hydrogen chloride, sulfur dioxide, or other acid gases.

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.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003ch3\u003eWhat is the NIOSH approval number for the SPR658?\u003c\/h3\u003e\n\u003cp\u003eThe SPR658 holds NIOSH certification under 42 CFR Part 84, Approval Number TC-84A-3538, for OV\/P100 combination protection.

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.\u003c\/p\u003e\n\n\u003ch3\u003eWhich GVS half masks use the SPR658 replacement filter?\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I know when to change the SPR658 cartridges?\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch3\u003eIs the SPR658 appropriate for spray painting with two-component urethane paints?\u003c\/h3\u003e\n\u003cp\u003eTwo-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.\u003c\/p\u003e\n","brand":"GVS","offers":[{"title":"Default Title","offer_id":44064839204952,"sku":"SPR658","price":23.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0594\/1900\/0920\/files\/OV-P100-Filters.jpg?v=1777877034"}],"url":"https:\/\/wcsafety.com\/collections\/gvs-respirators.oembed","provider":"WC Safety","version":"1.0","type":"link"}
