Our standards are based on a rigorous quality control process that we exercise before any product ever leaves our facility. The final quality control procedure our filters undergo is the microbiological laboratory test.

Microbiological laboratory tests indicate that Terra ceramic water filters works perfectly by removing pathogens resulting in safe drinking water in accordance to regulation from Indonesian Ministry of Health and World Health Organisation.

Laboratory results from Udayana Medical Center and University of Udayana are periodically updated and accessible here
