Review Summary:

Following a superbly practical 3-Stage Under Counter water filtration system, this product comes equipped with elements that make it better than a Watts RO system. A pre-filter works to extract sediments that might otherwise block the second and third filter stages. Places where tap water contains higher-than-average silt and sediment quantities will find this product a great fit for their clean water requirements. The flow rate is the same as that of Watts, though, and the equipment comes with a neat brushed-nickel faucet.

So you’re looking for a no-fuss water filtration system with decent performance that delivers clean, healthy water for your family’s needs day after day. Well, look no further than the Aquasana AQ-5300.55 3-Stage Under Counter Water Filter System. Enjoy the taste, purity and convenience of bottled water at much reduced costs right at home, without contributing to the carbon footprint with the endless disposal of water bottles.
