Consumers are increasingly shifting away from expensive bottled products and switching to water from their kitchen tap.This is according to the Tahlequah Daily Press, which says that almost half of its readers indicate they favour their water supply through a filtration system, rather than straight from the mains or from a bottled source.According to the article, local distributors of home water filtration systems have been receiving more and more calls about the products, indicating a change in thinking as consumers become more environmentally aware and conscious of the economic downturn.The paper cites experts from leading kitchen hardware firm In-Sink-Erator who say that a filter which can be used in conjunction with a refrigerator and ice-maker, for example, is the best option.In-Sink-Erator manufactures a range of kitchen tap products with in-built filtration systems. The Hot Water Filter tap features not only an effective filter but will deliver steaming hot 98-degree water on demand.
