Respiratory Mask Yato, Yato YT-74981

Product Type:

• A folding (flat‑fold) half‑mask respirator / protective mask

• Designed for respiratory protection against particulates, dust, aerosols

Protection Level / Standard:

• FFP2 class (filters up to ~94% of particles)

• Conforms to EN 149:2001 + A1:2009 standard (CE certified)

Structure & Materials:

• 4‑layer construction:
    • Inner working layers: filter media + special hot‑air layer (to reduce moisture inside mask) 
    • Outer layers: provide mechanical durability, comfort and structural support

• Made from materials such as PP (polypropylene), polyester etc.

Valve / Exhalation Feature:

• Equipped with an exhalation (breathing) valve to ease airflow outward during exhaling, which can help reduce internal heat / moisture buildup, especially during strenuous work.

Packaging & Quantity:

• Often sold in sets of 5 pieces per pack

• Also occasionally seen in other pack sizes (depending on supplier)

Intended Use / Application:

• Protection of the respiratory system from dust, smoke, mists / aerosols (solid particles and liquid aerosols)

• Not suitable for gases, vapors or environments that require chemical/organic gas protection.

• Commonly used in industrial, construction, woodworking, metalworking, or environments with airborne particulate exposure

Strengths & Limitations:

• Good balance of protection & breathability (via valve)

• 4 layers help with comfort, durability, and reducing moisture buildup

• Valve type masks do reduce exhalation resistance, but they do not protect others from the wearer’s exhaled air (so in infection control settings, some users prefer non-valved masks)

• As with all respirators, a proper fit (good seal) is crucial for effective protection
