Pureit Marvella RO+UV+MF is the fastest home-use water purifier in Bangladesh, purifying 20 liters of water per hour. Pureit Marvella RO+UV+MF has a 7-stage purification system which ensures you get water that is ‘Safer than boiled ” and removes excess total dissolved solids (TDS) to make your water tastier. In the first stage, the water passes through the Pre-Sediment Filter which removes fine and coarse particulate impurities/dirt. The second stage is the Pre-RO Carbon Filter that removes chlorine and organic impurities like harmful pesticides. It also adsorbs bad taste and odor-causing organic compounds from water. The third stage is the Post-Carbon Filter which removes the remaining dirt. Then the water passes through the RO Membrane at high pressure, with the help of an inbuilt pump. The RO removes dissolved salts, hardness, pesticides and heavy metals like arsenic, lead and mercury. It also removes microbial contaminants like bacteria, virus, protozoa and parasites. The fifth stage is UV filtration system, which provides an additional layer of purification for the water. The sixth stage is the Micro Filtration (MF) Membrane which acts as an additional assurance of safety towards microbial contaminants. The last stage is the Post-RO Carbon Filter, which removes bad odor and enhances the taste of purified water.
