Dust/hygienic masks are designed to protect the respiratory tract from medium and large dispersion non-toxic dusts. Yuta JSC produces two types of masks according to the standard BDS 7749-69:
Type 2 masks ‘Ozone II’, with a weight of up to 15 g and dust retention above 96%. Size of the fractions of the airborne particles they are capable of retaining is 5-10 microns.
Type 3 masks ‘Ozone III’, with a weight of up to 10 g and dust retention above 90%. Size of the fractions of the airborne particles they are capable of retaining is above 10 microns.
The ‘Ozone’ dust masks can be used without any risk of adverse side effects to the skin. The raw materials used have favourable derma-toxicological characteristics, they do not irritate the skin, and they exhibit no percutaneous toxicity or photoallergic activity.
Areas of application include all locations where coarse-grained dust is formed – gardening, logging, agriculture, milling, in the tobacco industry, etc.
