    Abstract: A water pitcher filter is provided. The filer includes a filter body formed from a bottom case and a top cap. The bottom case is adapted to retain filtration medium therein. The top cap includes an upper surface having an air outlet, a lower surface to engage the bottom case, a sidewall extending between the upper and lower surface and around a perimeter of the top cap, a nonwoven or net portion disposed on the sidewall and/or lower surface to allow unfiltered water to pass therethrough. The top case also includes a vent tube extending between the upper and lower surface and having a vent opening into the bottom case at the lower surface. In operation water passes through the nonwoven portion and into the bottom case where the filtration medium filters the unfiltered water and disposes filtered water into a filtered water chamber of a water pitcher.
