Half masks

Half masks have a very wide range of applications. They are a simple and inexpensive way to protect you against aerosols, vapours, gases, microorganisms, viruses and and similar hazards. The respirators are available with replaceable or integrated filters, as disposable or reusable products. Most of the FFP2 or FFP3 type fine dust masks for single-use by Dräger, 3M, Ekastu and other brands follow EN 149:2001.
