If you doesnt have any budget constrain. I suggest you take Icon model (Link to my website Click here to see Icon model) It have auto sterilization to make sure your water purifier more clean and free from any bacteria.

If you have limited budget and have a small family. I suggest you take a look at King top model. Flexible plan. You can choose plan according to your budget ( Click here to see King Top Model )
