What the GVS Elipse OV/AG/P100 Replacement Filters Protect Against

These filters combine three protections in one low-profile housing: OV (organic vapor — many paint and solvent vapors), AG (acid gas — chlorine, hydrogen chloride, sulfur dioxide, and similar), and P100 particulate at 99.97% efficiency for both oil and non-oil aerosols. That makes them a genuine, NIOSH-approved combination filter for work where solvent vapor, acid gas, and dust or mist appear together — and a step up from a particulate-only or odor-relief filter. They attach to the GVS Elipse mask as a tool-free twin-filter pair.

Two boundaries define where they belong. First, this is full protection, not the nuisance-level odor relief you get from a P100 nuisance filter — so it is the right choice when you have real organic-vapor or acid-gas exposure within its limits. Second, "combination" is not "universal": OV/AG/P100 does not cover ammonia, formaldehyde, or every gas. If your hazard is broader, GVS offers Elipse multi-gas filters that add those classes. And if you only face solvent vapor and dust — no acid gas — the lighter OV/P100 filter is a better match. Our acid gas cartridge guide helps you decide.

Where the OV/AG/P100 Fits in the GVS Elipse Line

GVS builds several Elipse filters that differ by what they cover. A P100 filter is particulate only; the P100 nuisance-odor filter adds odor relief but no rated gas protection; the OV/P100 adds real organic-vapor protection; and this OV/AG/P100 adds acid gas on top of organic vapor and particulate. Above that sit the multi-gas filters for the widest coverage. All of them fit the same compact GVS Elipse half mask or the Integra respirator with integrated goggles, so you can match the filter to the hazard without changing masks.

Frequently Asked Questions

What does OV/AG/P100 protect against?

Three things in one filter: OV is organic vapor (many paint and solvent vapors), AG is acid gas (such as chlorine, hydrogen chloride, and sulfur dioxide), and P100 is particulate at 99.97% efficiency for oil and non-oil aerosols. It is a combination filter, so it handles solvent vapor, acid gas, and dust or mist together on a GVS Elipse mask.

Is this full NIOSH protection or nuisance-level relief?

It is full, NIOSH-approved OV/AG/P100 protection — real respiratory protection against organic vapor and acid gas, not just odor relief. That is the difference from GVS's P100 nuisance-odor filters, which only reduce odor below the exposure limit. Use these OV/AG/P100 filters when you have actual organic-vapor or acid-gas exposure within their limits.

Which GVS Elipse masks do these filters fit?

They fit the GVS Elipse half-mask respirator in both S/M and M/L sizes, and share the Elipse/Integra bayonet, so they attach tool-free as a twin pair. Confirm you are running a GVS Elipse (or Integra) facepiece — the filter is the same across the size range; it is the mask body that comes in S/M and M/L.

Do these fit 3M, Honeywell, MSA, or Moldex masks?

No. The GVS Elipse bayonet is unique to GVS Elipse and Integra respirators and is not interchangeable with 3M, Honeywell/North, MSA, or Moldex facepieces. Keep the filter and mask the same brand so the NIOSH approval and the seal both remain valid.

What is the difference between OV/AG/P100 and the OV/P100 filter?

The OV/P100 filter covers organic vapor and particulate but not acid gas. The OV/AG/P100 adds acid gas protection — chlorine, hydrogen chloride, sulfur dioxide, and similar. Choose OV/AG/P100 when acid gases are part of your hazard; if you only face solvent vapor and dust, the OV/P100 is a lighter, lower-cost match.

What if I need protection against ammonia or formaldehyde?

OV/AG/P100 does not cover ammonia, methylamine, or formaldehyde — those fall outside the organic-vapor and acid-gas classes. For a broader mix, GVS offers Elipse multi-gas filters that add those gases. Match the filter's rating to a measured contaminant rather than assuming a combination filter covers everything.

Is this a pair, and do I replace both together?

Yes — it ships as one pair (two filters), because the Elipse is a twin-filter, dual-cartridge mask. Always replace both filters at the same time so each side has equal service life and balanced breathing resistance; never run one new and one used filter.

How often should I replace the filters?

Follow a written change schedule based on your exposure, not odor — some organic vapors and acid gases have poor warning properties, so you cannot rely on smell. Replace the filters sooner if you notice odor or taste breakthrough, irritation, or rising breathing resistance, and always replace a filter that is damaged or wet.

What makes the GVS Elipse different from a standard half mask?

The Elipse is known for its very low-profile, compact design — the filters sit close to the face, which improves the field of view and works well under a face shield or welding helmet. These OV/AG/P100 filters keep that slim profile while adding combination gas-and-particulate protection.

Do I need a fit test with the Elipse?

Yes. The Elipse is a tight-fitting respirator, so any workplace use requires an OSHA fit test and a user seal check each time you don it, and it will not seal over facial hair on the sealing surface. The filters only protect you behind a properly sealed mask.

Can I use these in an oxygen-deficient or confined space?

No. These are air-purifying filters — they clean existing breathable air but cannot add oxygen or protect in an unknown atmosphere. A confined space or a low-oxygen atmosphere requires a supplied-air respirator, and any exposure at immediately dangerous levels requires supplied air regardless of the filter.

Do I need the mask separately, or does this include it?

These are replacement filters only — the pair does not include the Elipse mask body. If you do not already own a GVS Elipse half mask, buy the mask (in your S/M or M/L size) plus a pair of filters. After that, you only reorder filters as they reach the end of their service life.

What is the SKU, and how do I reorder the right filter?

The store SKU is OVAG-P100 and the UPC is 5060233805051. Because GVS sells several Elipse filter types — P100 only, OV/P100, OV/AG/P100, and multi-gas — match the OV/AG/P100 rating (and the pair count) when reordering, not just the words "Elipse filter," so you get acid-gas coverage rather than a particulate-only pad.
