The Seccua Filtration removes turbidity and pathogens (viruses, bacteria like legionella, parasites and protozoans like amoebas, crypto and giardia) from water supplied from spring or well water. The UrSpring consists of a control unit and a replaceable filter. The Seccua filtration uses certified membranes with pore sizes down to 20 nanometers to filter the water. The filter is cost efficient and uses no chemicals or radiation.
