Frequently asked questions about this product

Answered by specialists

What hazards does this respirator protect against?: It protects against organic gases and vapours with a boiling point above 65 °C (such as solvent-based paints and adhesives) and medium levels of fine dust and mists via the P2 filter.
Can the filters on this half mask be replaced?: No, this is a maintenance-free mask with integrated filters. You replace the complete respirator once the filters become saturated, clogged, or breathing resistance increases.
How should this mask be stored between uses?: Store the mask in the supplied resealable bag in a clean, dry place. This prevents the bonded activated carbon filters from absorbing ambient air moisture and contaminants.
