1. A dispenser for a nutritional composition comprising: a water reservoir,a water heater that heats water to a temperature between 25 and 45° C.,a water pump,a water discharge device that receives a sealed disposable capsule containing a unit dose of infant formula in a form of powder or a concentrated liquid,a bacterial filter between the water heater and the water discharge device so that the heated water passes through the filter prior to discharge from the dispenser, the water pump passes the heated water through the bacterial filter for mixing the filtered water with the infant formula to form a reconstituted infant formula and dispensing the reconstituted infant formula,means to heat surfaces of the dispenser which, in use, will come into contact with filtered water, the means to heat the surfaces provided separately from the water heater and comprising a steam generator that delivers steam to, at least, the internal surfaces downstream of the bacterial filter to clean the bacterial filter and reduce adhesion and proliferation of bacteria and formation of biofilm in the water discharge device downstream of the bacterial filter, andcontrol means that operate steam delivery from the steam generator for cleaning and reducing the adhesion and the proliferation of bacteria and the formation of biofilm, operate water heating by the water heater, and operate the water pump for dispensing the liquid infant formula. 2. The dispenser of claim 1, wherein the filter is a flat membrane filter. 3. The dispenser of claim 1, wherein the filter is located adjacent to the water discharge device so that the heated water passes though the filter prior to the discharge device. 4. The dispenser of claim 1, wherein the bacterial filter has a nominal pore size of 0.45 microns or less. 5. The dispenser of claim 1, wherein the bacterial filter has a nominal pore size between 0.1 and 0.2 microns. 6.
