• an upper chamber having a lower portion removably received within the open upper end of the lower chamber;
• a filter medium located at least partly within one of the upper chamber and the lower chamber, the filter medium being positioned to filter water by gravity as it passes from the upper chamber to the lower chamber;
• and
• a seal coupled between the upper chamber and the lower chamber, the seal comprising a cavity receiving the upper rim of the lower chamber;
• wherein the seal comprises a gap extending to the cavity, the gap comprising a width smaller than the rim of the lower chamber when the seal is in a non-compressed and non-tensile state, the gap receiving a portion of the sidewall of the lower chamber;
• wherein the seal comprises at least two arced flaps contacting the upper chamber, a tip of each arced flap defining a circular inner opening of the seal;
• wherein the seal comprises at least two first barbs contacting the upper chamber, each first barb forming a circle;
