Posted By Kevin West Try sundstrom RPE. You can find their products on: http://www.sea.com.au/prods/pnc_sund.htm They provide an extensive range of RPE from orinasal (half)face masks to full face masks with or without positive power. I dont think they supply disposable respiratory devices but then again I would prefer not to use them when dealing with asbestos. The organisation I work for carry out work with asbestos regularly (surveys and air sampling including clearance testing) and we use these products. Hope this is useful, Kev
