I have been using this purifier from 2008 and I can say it is very useful for our family. It is cheap and requires no electricity for water purification. It gives very clean water. This purifier is easy to use and it is hassle free to install. Only you have to change the battery when it is completely used. The battery lasts for 2-3 month depending on how much it is used for purification of water. It is worthy product to buy. It looks very stylish.This filter is also very easy to clean. I am using brown color which I think is very cool looking. It takes very less time for water filtering. Pureit customer service is also good. If you want a good water purifier with low budget then you can go for this product and I am sure you will not regret.
