1) Figure out the type of water purifier you want
Water quality and the contaminants present are important determinants when figuring out the type of water purifier. For water with high levels of Total Dissolved Solids (TDS), an RO-based purifier is a smart choice. You can opt for a UV/UF-based water purifier in case the water has lower levels of TDS. However, there are water purifiers with RO+UV+UF technologies that eliminate all the impurities and ensure healthy water supply.
2) Check the storage capacity
Depending on the size and water consumption pattern of your family, go for a purifier that stores sufficient water. This ensures that there is ample drinking water even in case of a power outage.
3) Determine its cost efficiency
The water filters of a purifier need to be replaced on a regular basis. The cost of replacement is subject to the type and model of the purifier. Opting for annual maintenance will definitely be a smart move to ensure that you get the most of your investment.
