OVP-10 Combination Filter (A2P3) | TinBreather Gas Mask Replacement Filter

OVP-10 A2P3 Combination Filter — Replacement Gas Mask Filter for TinBreather

The OVP-10 is an A2P3 combination gas mask filter designed for use with the TinBreather Full Face Gas Mask. Rated for organic vapor protection (A2) and the highest class of particulate filtration (P3), the OVP-10 provides reliable respiratory protection against chemical vapors, toxic gases, wildfire smoke, biological aerosols, and radioactive particulates.

PROTECTION RATINGS EXPLAINED

• A2 — Organic Vapors: Protects against organic solvents, hydrocarbons, and chemical vapors up to 1000ppm. Class 2 capacity for extended use in chemical environments.
• P3 — Particulates: Highest EN 143 filtration class. Filters ≥99.95% of airborne particulates including fine dust, smoke, biological aerosols, mold spores, and radioactive particles.

WHAT THE OVP-10 PROTECTS AGAINST

• Organic chemical vapors (VOCs, solvents, hydrocarbons)
• Wildfire smoke and toxic combustion particulates
• Biological aerosols and airborne pathogens
• Radioactive dust and nuclear fallout particulates
• Industrial solvent and chemical fumes
• Fine particulate matter (PM2.5 and below)

OVP-10 vs OVP-11 — WHICH FILTER DO YOU NEED?

The OVP-10 (A2P3) is the right choice for organic vapor and particulate protection — covering wildfire smoke, biological aerosols, radioactive dust, and general chemical vapor threats. If you also need protection against inorganic gases (chlorine, hydrogen cyanide), acid gases, and ammonia, upgrade to the OVP-11 (A2B2E2K2P3) for maximum NBC/CBRN coverage.

FREQUENTLY ASKED QUESTIONS

What does A2P3 mean on a gas mask filter? A2 indicates Class 2 organic vapor protection (up to 1000ppm). P3 is the highest European particulate filtration class at ≥99.95% efficiency. Together, A2P3 provides strong defense against both chemical vapors and airborne particles.

How long does the OVP-10 filter last? Sealed shelf life is typically 5 years. During use, replace when you detect odor breakthrough, after any significant exposure event, or per manufacturer guidelines. Always keep sealed until use.

Will the OVP-10 fit other gas masks? The OVP-10 uses a standard 40mm NATO thread (EN 148-1) and is compatible with most full face masks using this thread standard. It is designed and tested for the TinBreather.

Does the OVP-10 protect against nuclear fallout? The P3 rating filters radioactive dust particles and fallout particulates at ≥99.95% efficiency. Combined with a proper face seal, it significantly reduces inhalation of radioactive particles. It does not protect against gamma radiation.

Is the OVP-10 good for wildfire smoke? Yes. The P3 rating makes it highly effective against wildfire smoke, fine particulates, and combustion byproducts. It is one of the most effective options for smoke inhalation protection.
