Have bought pure it advanced 23 litre 2 days back, I m extremely disappointed from the performance, you can not fill the filter completely, wait till lower most compartment of filtered water is empty which contains only 9 litre.the why you people claim a 23 litre water filter.i have used usha filter earlier there was no such issues with that.if u’ll fill it then as soon as lower most compartment get filled it start leakage and whole kitchen becomes wet.extremely disappointing
