Filtration Capabilities: The system uses two stages of filtration to provide you with pure and clean drinking water. At the first stage, the multi-grade sediment filter with 4 layers of filtration stops rust, dirt, sand, and other particles from going to the next filter. It can successfully filter 95 per cent of sediments with a size of 25 to 1 microns.

The second stage is the activated carbon filtration stage; the filter uses KDF 85 to remove heavy metals like lead, mercury, copper. It also removes chlorine, chloramines, bacteria, viruses, insecticides, herbicides, and pharmaceuticals. The system does not remove TDS from your water source, thus retaining the healthy minerals in your water supply. The system uses large filters with a size of 28 x 18 x 9 inches. Such a large size increases the flow rate and makes the filters last longer than the usual recommended time. Filters have a life span of 1-year.
