The Astra Agate dirt trapper mat absorbs fine dirt and moisture and is ideal for indoor use. Its backing is free of harmful phthalates, which makes it suitable for floors with underfloor heating. The coating makes the clean-off mat non-slip and the narrow running edge all around prevents tripping hazards. The mat is not only available in standard sizes, but also in rolls. Contamination on the doormat can be removed with a little water, brushed out or vacuumed.
