Unshaped filtering half mask protects from solid and liquid aerosols (dust, smoke and fog) and allows you to work and operate in conditions of low air pollution, low and high temperatures (from –30 ° С to + 70 ° С) or at high humidity. The respirator has a comfortable, crush-resistant cup shape. It fits comfortably to a face because of its wide edge, flexible aluminum nose clip and high elasticity ear loops. Special electrostatic filter with the enhanced electret properties traps even the tiniest particles. One more key feature is low breathing resistance, it is easy to breathe even during the very long periods of usage. The respirator can be used for six to eight hours.
