- Sediment Filter:-This tap is the first stage of water purification that provides water without coarse impurities or sediments.
- Pre-Activated Carbon Filter cum Adsorber:-Envy plus RO water purifiers Nepal is a benchmark among water purifier manufacturers.
- Carbon Block Filter cum Adsorber:-This stage more decontaminates water by adsorbing leftover chronic and organic impurities like pesticides. Another function of carbon block filters is to rid the resulting water of any odor-causing organic matter. The block advertises bad taste-causing contaminants.
- Reverse Osmosis (RO) Membrane:-The RO membrane is the heart and soul of this water purification system. Water from the previous filtration stage is processed to get rid of germs like bacteria, viruses, and protozoa, and dangerous chemicals like pesticides and herbicides.
- Carbon Filter:-Any residual impurity that will be loose from the abovementioned processes gets sublimated during this stage. This can be the last stage of purification that gives pure, odorous water.
