1. A system comprising:
a line set connected to a purified water outlet connector, wherein the line set includes at least one sterilizing filter; and
a water purifying apparatus fluidly connected with the line set, the water purifying apparatus including
(i) a pre-filter circuit connected to a water inlet for receiving water from a water source, wherein the pre-filter circuit includes a particle filter and an activated carbon filter, wherein each of the particle filter and the activated carbon filter are arranged to filter water received via the water inlet to produce pre-treated water,
(ii) a fluid circuit arranged to receive pre-treated water from the pre-filter circuit and to produce purified water, wherein the fluid circuit includes
a pump,
a reverse osmosis device, and
a heating device arranged to heat purified water output from the reverse osmosis device to a temperature above 65° C., and
(iii) the purified water outlet connector, wherein the water purifying apparatus is configured to
pump pre-treated water through the reverse osmosis device using the pump,
produce purified water using the reverse osmosis device,
disinfect the fluid circuit using the heated purified water output from the heating device, and
after heat disinfection is completed, output purified water through the purified water outlet connector,
wherein the at least one sterilizing filter of the line set is arranged to further filter the purified water.
