The membrane keeps all impurities, such as dissolved solids, chemical residues, bacteria and viruses, on the other side.

The unit is easy to use. It has been tested and is ready to use when delivered from the factory. The filters are already installed. The end user only has to attach the inflow, outflow and production tubes to the unit using the clamps that come with the package. The pre-filter also has to be attached to the end of the tube and submersed in the source of untreated water. Once the unit has been plugged in, the unit is ready to be turned on with the on/off switch.

How long can the SolarRO unit and filters be used safely?

Our unit has been designed for continuous use. It’s a good idea to select the size of the unit based on household water consumption, in which case the interval for changing the pre-filters is planned according to assumed flow volumes.
The SolarRO unit is manufactured from quality components in Finland, and it has a one-year guarantee. The interval for changing the filters varies according to the quality of the untreated water and hours of operation. On average, the filters should be changed 1-2 times per summer.

How long does a reverse osmosis membrane last?

The membrane has a service life of 2-3 years when properly used. The reverse osmosis membranes function better when they are used continuously rather than occasionally. Never allow the reverse osmosis membranes to dry out. Do not let the unit freeze during the winter. During the winter, antifreeze fluid must be added to the unit or it must be stored in a warm place.
