The market is flooded with water purifiers based on different technologies, each with its own set of benefits.
Here’s how you can pick the right water purifier.
1) Figure out the Type of Water Purifier You Want
It’s important to take into consideration the contaminants which are present in the washer before buying a water purifier. If the water has high levels of Total Dissolved Solids (TDS), we would suggest investing in an RO (Reverse Osmosis) based purifier. If the water purifier has low levels of TDS, then an UV (Ultraviolet) or UF (Ultrafiltration) based water purifier is your best bet. However, there are water purifiers with all three- RO+UV+UF technologies that eliminate all impurities and give you a healthy glass of water. So it’s important to ask or check if the one you’re buying has these features.
There are some other types of purifiers— such as a non-electric purifier— which filters water that has low levels of TDS with the help of gravity and multi-stage filtering levels. An electric purifier uses electricity for RO to pressurise water to filter through the membrane and for UV radiations to kill microbes.
These purifiers are most suited for water with high levels of TDS.
2) Check the Storage Capacity
Depending on the size and water consumption pattern of your family, choose a purifier that stores sufficient water. This ensures that there’s ample drinking water even in case of a power outage. Non-electric purifiers can store up to 25 litres of filtered water at one time, whereas electric ones can come with a storage tank of up to 12 litres of capacity. Also, keep in mind that RO purifiers produce 3 litres of waste water for every 1 litre of purified water.
3) Set a Budget
Consider the TDS level of water in your water supply and set up a budget. A non-electric purifier can be bought for around ₹5,000 and electric ones range from ₹6,000 - ₹20,000, depending on whether you pick RO, UV or UF.
It’s important to be informed about your options when it comes to water purifiers.
