Abstract

An apparatus for making drinks such as filtered water, coffee, espresso or tea which comprise a cold water filter system for purifying water for either direct consumption or use in extracting flavor-containing materials like coffee and a hot water filter assembly located on the brew head for removing impurities originated from both water itself and the parts of the apparatus in contact with water. The cold water filter system comprises a removable water container having at its bottom a water passageway, a filter cartridge removably mounted in the water passageway, a containing chamber for receiving the filtered water, and a valve in the water passageway for closing the passageway when the container is removed from and opening the passageway when placed onto the containing chamber. The hot water filter assembly comprises a filter cartridge having a hot water inlet and an outlet, a water-tight seal formed between the brew head and cartridge inlet and encircled by an elastic sealing ring, and a fixture for removably receiving the cartridge and retaining the cartridge in position to maintain the water-tight seal during the operation of the apparatus.
