Abstract:
A method of purifying water using a water filtration assembly including a first housing having upper and lower end portions and defining a reservoir for water to be purified, and a filter housing having a treatment media with active sites disposed therewithin, an inlet port for receiving water from a lower end portion of the reservoir, and an outlet port for purified water, said method comprising:(a) flowing water to be purified into the reservoir through an opening defined in the upper end portion of the first housing, at least some of the water to be purified flowing from the lower end portion of the reservoir through the inlet port into the filter housing, the inlet port guiding the water to be purified to a back and bottom of the treatment media; (b) maintaining the water to be purified in the filter housing for at least about 30 seconds in contact with the treatment media disposed therewithin, to effect removal of contaminants therefrom, wherein the treatment media comprises a static treatment media bound to a substrate such that migration to the active sites is accomplished through diffusion; and (c) dispensing through the outlet port water that has been purified in and exited the filter housing.
