Water Purifier Buying Suggestions

Namaskara, I am thinking of getting a water purifier at our house. This would be the first water purifier we would buy in our family (we have been boiling water and drinking it) On YouTube, I can see that people are recommending Urban Company Native M1. But not sure if we can get this here. Need your suggestions on which would be a good water purifier to buy along with the maintenance cost.
