    摘要： In accordance with the invention there is provided a water filtering device for attachment to a faucet comprising a generally tubular passage with an inlet for water from the faucet at its upper end and an outlet for water at the lower end, an annular water filtering chamber surrounding the passage, openings between the lower axial end of said chamber and the lower portion of said passage, openings between the upper axial end of said chamber and the upper portion of said passage, and a valve in said passage movable for blocking the flow of water directly from the upper portion of said passage to the lower portion of said passage whereby when said valve is closed water from the faucet is caused to flow from said passage into and through said filtering chamber and then back into said passage and out of the water outlet. Further in accordance with the invention there is provided a filter for the filter chamber, the filter having an arrangement of filtering layers which provides highly pure water while at the same time providing extended useful filter life.
