When choosing a water purifier in India, you can consider things like: 1. Water quality: Understand the quality of your water, including its source, TDS levels, and the best TDS for drinking water. Water from lakes, rivers, and harvested rainwater has a lower concentration of TDS. 2. Purification technology: Reverse osmosis (RO) is recommended for hard water, while UV is recommended for soft water. 3. Capacity: Consider how much water your family drinks and how much output you need. Water purifiers generally have a storage capacity of 4–25 liters. 4. Maintenance costs: Consider the cost of filters and AMC plans. AMC plans are usually cheaper than buying filters and membranes separately. 5. Service quality: Make sure your area is covered by the brand's service coverage. 6. Electric or non-electric: Electric water purifiers need a power output to work, while non-electric ones do not. Non-electric purifiers generally have a lower capacity
