For domestic filters for hot water, cleaning is handled by backwashing. This eliminates the need to replace the cartridge, and you simply release the water with trapped impurities through a tap at the bottom of the water filter from time to time. Some domestic filters for hot water can be upgraded with an automatic backwash unit, which will clean the filter at a preset interval for you.
Additionally, a domestic hot water filter can be easily supplemented with a pressure reducer. A hot water filter is suitable for the supply pipe of every family house or apartment.
