Configuration: super filter + coconut shell activated carbon filter + heavy metal free filter
 0.01microns aperture ultrafiltration membrane can filter sediment, rust, suspended solids, red insects, algae, bacteria and viruses, with the bacteria filter rate being up to 99.99%.
Imported from Sri Lanka, coconut shell activated carbon has high adsorption ability for iodine and organics, thus removing the color and nasty smell to offer better taste. 
SUBM carbon technology ensures a filter rate of more than 90% in riding heavy metals such as lead, cadmium, mercury.
