All Water purifiers are same, just the point of concern is After-sale-service. Which distinguishes HUL from others. AquaGuard starts with a price range of 8500/- and the guy who came to show me demo was very rude and a very-bad marketeer.
Also, Ive heard After-sale-service of AquaGuard is very pathetic!! However, Pure It stands apart from others. After-sale-service as promised over call (within 48 hours) is a commitment. Very focussed on customer satisfaction.
Products are cheap and affordable to any middle class family. Also, easy to use. Go for it.
