When it comes to the best water purifier in Bangladesh, RO water purifier is unrivaled in practically every way. They are more powerful than UV water purifiers since they often include many filtering stages. They are also less tough to maintain and are ideal for large families. UV treatment with reverse osmosis is necessary if the water source contains a high microbiological concentration. By running the water through a UV disinfection technology, bacteria, viruses, and algae can be destroyed. However, some people choose to use water purifier tablet, which does not filter sediment or chemical impurities. It is preferable to filter the water before applying purification tablets. Some compounds are less efficient or useless against specific bacteria, notably protozoans.
