An apparatus and methods for making drinks such as cappuccino, latte, espresso, coffee or filtered water which comprise a cold water filter system (11) for purifying water, a hot water filter assembly (16) located on the brew head for removing impurities originated from both water itself and the parts of the apparatus in contact with water, and/or an automatic milk frothier (14) for frothing the milk. The cold water filter system comprises a removable water container (21) having at its bottom a water flow passageway (23), a containing chamber (24) for receiving filtered water, and a valve (25) in the water flow passage. The hot water filter assembly comprises a filter cartridge (128) having a hot water inlet (129) and outlet (130), a water distribution chamber (132) formed between the brew head and cartridge inlet and encircled by an elastomer sealing ring (135), and a fixture for removably receiving the cartridge and retaining the cartridge in position to maintain the water distribution chamber intact during the operation of the apparatus. The milk frothier comprises nozzle means (80) for transforming the steam into a steam jet, a chamber (83) having an inlet port for receiving the steam jet, liquid passageway means (87) for drawing liquid into the chamber and an outlet port below the inlet port, liquid jet means (88) for transforming the liquid in the chamber into a liquid jet, an arrangement that allows the liquid jet to thrust into the liquid in a containing means and thereby producing fine air bubbles or foam, and foam level control means (90).
