I would suggest you to first know what type of water you get. This is a very simple step towards buying the right water purifier for home use. Get the tap water tested by the best water purifier company. I bought Livpure Water purifier and so I got the test done with Livpure water purifier company.
It tells you the level of TDS, the level of salts and minerals in water. Hence if you avoid testing your water than you will miss choosing the right and best water purifier. Livpure reverse osmosis purifier is the right water purifier. This purifier not only removes the insoluble soilds but also kills the bacteria and diseases spreading viruses and germs.
