Frequently asked questions:

How to choose the best water purifier for my home?

The first step you need to do is to check the TDS level of the water supply in your home. Based on the TDS level, you need to choose the ideal RO water purifier for your home. If the water's TDS level is less than 500mg/liter, you can go for a UV water purifier for your home. If the TDS is more than 500 mg/liter, you must go for an RO water purifier with a TDS adjuster.

Which one is best - boiled water or RO water?

Boiling the water helps you get rid of harmful bacteria and other germs, but it does not help get rid of TDS.  In that case, the RO water purifier works best.

Why RO is banned in some places?

In the places where TDS is less than 500mg/liter, then RO is not required. As RO excessively purifies water, in that case, the areas where the TDS level is already less than 500mg/liter, RO makes water level has very low TDS, which makes the water acidic and that is harmful to health.

Which type of water purifier is best in India?

Experts say that water purifier having UV is best in India, as it retains the essential minerals and is ideal for our health.

A quick chart for ideal water purifier based on the level of TDS value present in water at your location:

TDS Value Impurities Present Ideal Purifier
Over 300 ppm Turbid/Muddy water+ Bacteria RO+UV+UF purifier + TDS controller
Over 300 ppm No impurities as such RO water Purifier + TDS controller
Over 300 ppm Turbid/Muddy water+ Bacteria UV+UF water purifier
