Water filters with tank

Water tank

— presence of a tank in the reverse osmosis system. It provides a convenient and necessary supply of clean water (since the filtration process itself is slow) and is installed after the membrane, before the final purification stage (post-filter). Inside the tank, there is a compartment with pressurized air, which enables water to be expelled when the tap is opened. This is why the usable volume of the tank is less than the total volume.
