The RO filters out heavy metals, bacteria, viruses, scales, organic matter, and other impurities with precision up to 0.0001 microns. The PAC absorbs odor and organic substances from the water and furthermore improves the taste. Lastly, the tank kills bacteria with UV sterilization every 4 hours for 25 minutes.
