4D Purification™

This innovative approach involves the application of spatially-placed Dual UV-C LEDs that offer a vital time-dependent treatment to the water before it undergoes the conventional 3- Dimensional filtration. As a result, the water you sip through the spout is subjected to an additional layer of filtration, hence the term 4D Purification™.

Yes, tilting is required as water has to pass through the filter using gravity and a little bit of suction force. Because of the floating design of the filter. Which was intentionally created to avoid reverse contamination (RC). RC is a major drawback of all the filters in the market. They sit inside the water, and over time they reserve contaminate the water.
