WaterCode have improved hollow fiber membrane technology with lower gravity working pressure and fine poresize.  the poresize @ 0.1 & 0.02um 100% ensure no bacteria would get through membrane wall. Moreover,a stronger membrane structure can withstand backwash pressure which allows the filter to be cleaning and reused.

Graviy working

Our patented membrane is only required a lowest trans-membrane-pressure, even can work even at water height 2mm gravity, it is permanentyly hydrophilic allow largest flow at the lowest pressuur, so that no any electricity consumption, suitable for rural remote area and outdoor

Simply operation & maintenance

a simple replacment or maintenance ensure your longterm usage of cleaning water.  you can backwash the filter with water or sodium hypechloride etc.
