Dust Control Mats, once placed at strategic entrances to buildings, lifts, and washrooms, these mats trap dust and moisture, and therefore reduce the subsequent soiling of carpets and floor surfaces. From studies carried out on the transfer of foreign material indoors into buildings, it has been shown that 70% of the dust is brought in by visitors to the buildings. With the Dust Control Mat, 94% of the dirt is trapped before it goes any further than the threshold.
