BWT-A40 Child lock feature to ensure safety（40Liters/Day）

First of all, every day we breathe the air normally, and there is no filtration and purification protection during the whole day. The surface water sources on the earth are derived from precipitation which is formed by the air. Compared with the surface water sources, the air sources are not contaminated by the surface (such as industrial pollution, agricultural residues, etc.).

Our air water machine need to go through the process of air filtration system before the water is produced. The suspended matter and particulate matter in the air above 0.3 microns have been blocked outside the system. Specifically, the raw water after air filtration has at least reached the municipal water quality standard , and after the multi-stage purification, the clean drinking water is fully up to the national standard and can be safely consumed.
