Comparison Aquafilter RXRO675P vs Aquafilter RXRO675

The lowest inlet water pressure at which the filter is able to fully perform its functions. Indicated for models with a connection to the water supply — directly or through a tap (see "Connection").

The design of some filters requires a certain level of inlet pressure for normal operation; if the pressure is insufficient, both throughput and overall filter efficiency suffer, and some functions are not available at all. The latter is especially true for reverse osmosis (see above). Therefore, if the minimum operating pressure is directly indicated in the filter characteristics, you should make sure that your water supply system complies with this parameter before purchasing.

Note that for filters with a booster pump, this column indicates the lowest pressure at which the filter still does not require the use of a pump; see "Pump" for details.

The filter has its own pump. This feature is found mainly in two types of filters. The first is reverse osmosis systems (see above): the operation of such filtration requires high pressure, but it is not always achieved at the inlet, and a pump, usually electric, is provided to increase the pressure. The second option is tourist filters (see "Type"), where the pump is designed to draw water from natural reservoirs; they have to be pumped manually.
