GVS SPR474 Elipse OV/AG-P100 Replacement Filters

These are replacement filter cartridges for GVS Elipse OV/AG half-mask respirators, sold as a pair covering both S/M and M/L mask bodies. Each cartridge combines activated carbon with a selected pore structure for organic vapor and acid gas adsorption, plus pleated P100 media for 99.97% oil-proof particulate filtration. Installation follows the individual mask body's user manual and involves pulling the strap tab and seating the housing. Community reviewers report easy breathing and satisfactory comfort during extended use. The cartridges are NOT compatible with the SPR457 P100-only mask body despite superficial similarity — the SPR457 uses an integral strap and glued inhalation valves that conflict with the OV cartridge's built-in valve design. At $39/pair the price is competitive against the 3M 60926 multi-gas + P100 cartridge ($45–55/pair), though the 3M includes verified TC-84A documentation the GVS listing does not provide.

Owners who already run a compatible GVS Elipse OV/AG mask body (SPR466, SPR467, SPR472, or SPR473) and need replacement cartridges. The filter class covers the realistic span of car-care exposures — paint-prep solvents, rust converters, and sanding particulate — in a single cartridge. Skip if starting fresh with a new respirator system: the 3M 60926 on a 6500 or 7502 body provides documented TC-84A verification and published service-life data that GVS does not currently provide for this listing. Also skip if you only own the SPR457 P100-only mask — these cartridges will not seat correctly without voiding NIOSH compliance.

No chemical or particulate hazard from handling the sealed cartridge in normal use — the filter media is enclosed in the housing. Spent cartridges carry adsorbed organic vapor, acid gas, and particulate chemistry from whatever was being filtered. Spent cartridges should be sealed in a plastic bag and disposed of according to local hazardous-waste guidance — they carry adsorbed chemistry from whatever was being filtered. Once removed from sealed packaging, the manufacturer-published shelf-life shrinks to roughly 6 months for OV cartridges — humidity degrades activated carbon between uses. Relying on taste or smell to detect breakthrough means the user has already had unprotected exposure. Track usage hours against the manufacturer's service-life spec, and change cartridges on a schedule. The plastic housing and bonded filter media are landfill-bound — no consumer take-back program is documented.
