Claim 11:
12. A method comprising:
placing a drip tray onto a cooler reservoir, wherein the drip tray includes a rim which is operable to be received by the cooler reservoir to maintain the position of the drip tray over a reservoir receiving portion, wherein the drip tray includes a recess operable in a filtering configuration to receive a filter bucket on top of the drip tray;
placing the filter bucket onto the drip tray, wherein the filter bucket includes a filter installed therein;
pouring water to be filtered into the filter bucket from a transfer bucket;
filtering the water from the filter bucket through the filter, and into the reservoir receiving portion of the cooler reservoir, wherein the recess of the drip tray and the rim coupled with the cooler reservoir prevent leaked water or unfiltered water from gaining access to the reservoir receiving portion; and
nesting, in a storage configuration, the drip tray and the filter bucket such that the drip tray and the filter bucket fit within the reservoir receiving portion of the cooler reservoir when a lid is closed over the cooler reservoir, wherein in the storage configuration, the drip tray is configured to be inverted from its position in the filtering configuration to be nested in the filter bucket,
wherein the drip tray and the filter bucket are operable to be nested, in the storage configuration, within the transfer bucket such that the drip tray, filter bucket, and transfer bucket fit within the reservoir receiving portion of the cooler reservoir when the lid is closed over the cooler reservoir,
wherein the lid is operable to form a seal with the cooler reservoir when the lid is closed to completely cover the reservoir receiving portion.
