V FFP2 NR D disposable filtering half mask is a complete respiratory protective device used for protection against aerosols of solid and liquid particles. Particle filtering half masks are designed for respiratory protection against aerosols of solid particles or water-based aerosols (dust, smoke) and liquid aerosols (mist), provided that the dispersed-phase concentration of these aerosols in air does not exceed 10 x TLV. The facepiece of the half mask has a nose clip, exhalation valve and two non-adjustable head harnesses made from synthetic rubber bands. The half mask is easy to adjust to the shape of the face and remains comfortable throughout prolonged use. The exhalation valve reduces carbon dioxide concentration and moisture inside the facepiece and exhalation resistance.
