The water that comes from the municipal corporation is not thoroughly treated and cleaned. It is loaded with chemicals to treat the pathogens. During transportation, water is bound to get mixed with various contaminants before they reach our taps. To eliminate these contaminants and to make it fit for consumption, purification is essential.
Here’s how you can pick the right water purifier
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 a healthy glass of water. Some other kind of purifiers you can check out.
- Non-electric purifier
They filter water that has low levels of TDS with the help of gravity and multi-stage filtering levels.
- Electric Purifier
An electric purifier uses electricity for RO to pressurise water to filter through the membrane and for UV radiations to kill microbes. They work wonders on water with high levels of TDS.
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. The non-electric purifiers can store up to 25 litres of filtered water at one time whereas the electric ones can come with a storage tank up to 12 litres. Also, keep in mind that RO purifiers produce 3 litres of waste water for every 1 litre of purified water.
3) Where and how to buy
It is important to be informed about your options when it comes to water purifiers. Considering the health and TDS of water in your living area and other necessities, set up a budget. A non-electric purifier can be bought at around ₹5,000 and electric ones range from ₹6,000 - 20,000, where you can pick from RO, UV or UF.
4) Drinking water specification
A water purifier has to commit to certain standards set by NSF (National Science Foundation). They are regulated by US EPA (US Environmental Protection Agency). They have derived standards for the purifiers and its extent of purification.
