First Stage
Purification Filter At the suction opening of the pump, it removes
algae and large floating matter by means of a resin fiber
suction filter and coarse unwove cloth.
Second Stage
Purification Filter A chemical fiber spool-type filter that
removes floating matter larger than 5 microns including
Algae, Rust, and Grains of sand, and protects the membrane.
Third Stage
Purification Filter A Pleat-type membrane filter, same grade
as used in generation pure water in the semiconductor industry,
effectively filters and removes microbes and bacteria through
its microscopic openings of 0.05 microns. Furthermore,
fibrous activated carbons are employed to absorb ionized
toxic substances, and copper fiber filters and used for
sterilication. All these arrangement combine to produce
safe drinking water that meets most strict standards.
