Wikipedia talk:Articles for deletion/Hega

There is no citation for the claim that the carbon cloth is more efficient than the granular activated carbon filters. If this is the case, why is granular carbon still in such widespread use and the carbon cloth only used in cases where the odour levels are likely to be minimal? This claim should be removed from the article and I would question this article's right to exist at all. It sound suspiciously like a version of a discredited product called Ultracarb, which promised much and delivered very little some years ago.Jscb (talk) 07:44, 19 October 2011 (UTC)
