Reverse Osmosis Preparation Filter (PP)
Reverse Osmosis Preparation Filter ( Polypropylene ( PP )) removes the last impurities after carbon filtration and prepares the water for the Reverse Osmosis ( RO ) membrane.
This filter is, among other, special advantages of the Wetality water system.
Most water filtration systems rely on Carbon filter to do all the dirty work and place RO filter directly after it.
Because carbon filters have been found to leave small amounts of filtration contaminants (particles caused by filtration itself, not originally present in water) in the filtered water, we have placed this RO preparation filter between them.
