ABSTRACT:
A low cost, pressure insensitive, highly accurate portable house dust wipe template sampler having a dust pick-up element and a corresponding template having an aperture which exposes a testing surface of predetermined area. The dust pick-up element is comprised of a porous polyethylene "draindisc" filter removably mounted on an inert non-porous plastic body having a gripping handle. The polyethylene filter is sized to snugly fit across the sampling template of predetermined area. Three wipes within the template area by successive polyethylene filters provide a dust mass recovery efficiency/per given area of the template, in excess of 95%.
