ABSTRACT:
A filtration apparatus for reducing contaminants in water used for household purposes and the like. The apparatus includes a water container with a receiving reservoir mounted in the container. The reservoir houses a filter and a first passage is formed at the top end of the reservoir for connecting the reservoir with the filter. A second passage permits the flow of water from the first passage into contact with a barrier wall spaced away from the first passage. A first chamber defined between the first passage and the barrier wall is connected by means of a third passage to a second chamber located on the other side of the barrier wall. The filter also includes a bottom wall defining openings communicating with the second chamber. Filtering material is located within the first and second chambers so that water introduced into the receiving reservoir passes downwardly through the first passage, transversely through the second passage into the first chamber, upwardly through the first chamber, and then transversely through the third passage to the second chamber. The water then travels downwardly through the second chamber and outwardly through the bottom wall openings for entering into the water container.
