Hi frnds, I want to share my experience for pureit compact water purifier, the main thing is there is no use of electricity. every one know that water should be clean is very essential for everyone life, In this the purifier has a signal, if you see the signal is green that water is purifying and if this convert in to red then we have to Chang the this very easily. I am using this product since four year, so we can say that the durable quality is good. we can clean it at regular basis and very easily done with less time so it's time consuming also and very easy to use. this also stylish product and service is good. if we want to that change the red signal to green, so service is best. I appreciate this product.
