Water purifiers
Purifiers
— the name of this type of device very clearly reflects their main difference from coolers: purifiers are equipped with built-in filters and can not only heat/cool water but purify it from various impurities. At the same time, the possibility of such filtration can be very extensive; many models support capillary cleaning, reverse osmosis, UV radiation disinfection, etc. (see "More features"). Thanks to this, purifiers can use water not only from bottles but even from an ordinary water supply.Most devices of this type are intended specifically for connection to the water supply. For more information about this connection, see "Water supply".
