Please let me know the points to be consider before buying water purifier for homes.
Secondly, I cam across Elkin make water purifier manufactured in Gaziabad under brand name bio pure, will you please let me know whether this is a good water filter to buy?
Thirdly, whether the rain water if purified with water filter can be used for drinking purpose ?
Can we have common tank with the help of rain water harvesting system ?
