In this case is implied the temperature of the water for which the filter is designed. This parameter is directly related to the maximum operating temperature (see below). In general, modern filters fall into two main categories:
—
For cold water. Exactly this purpose that most models today have, regardless of type. This is due to two points: firstly, cold water has to be filtered more often than hot water, and secondly, filter elements for such a temperature are simpler and cheaper. The temperature limit of cold water is usually held at around 40 °C.
—
For hot water. Filters designed for connection to hot water systems.
When choosing a filter for its intended purpose, note that the use of “cold” filters with hot water should never be allowed. On the one hand, hot water usually has more impurities than cold water, which reduces cartridge life and cleaning efficiency. On the other hand, high temperature itself is an abnormal mode for filter materials, and instead of water purification, the opposite effect may even occur — the release of harmful substances from the cartridge. Therefore, for such cases, only filters designed for the corresponding temperatures should be selected.
On the other hand, the use of "hot" filters with cold water is quite acceptable — most of these models provide this possibility in case the hot water supply is turned off. However, fo
...r constant work with cold water, it does not make sense to purchase such a filter, if only because it will cost more than the “usual” one.The highest inlet water temperature at which the filter is able to operate normally. Modern filters are conditionally divided into models for cold and hot water: the operating temperature in the first case does not exceed 40 °C, and in the second it can reach 95 °C.
