The Purr Advanced Faucet was an amazing investment.Taking my not so great tasting water and making it clean,healthy to drink,and great tasting.I finally can stop spending hundreds of dollars a year buying cases of water and now get the same great quality right out of my very own faucet.Love how easy it is to use,just by flipping a switch I take my regular water over to the Purr filtration system and by pushing the switch up go right back to washing my dishes.The cool part is the added light up switch feature that lets you know when its time to change out the filter.The filtration lasts about 3 months,give or take.The only downside is it's slow pouring,but all the benefits outweigh that disadvantage.Love knowing I'm giving my family the best quality.
