I own an aqualife water filter that was very advertized and as a family with children our family decided to have that system for better health. in 8 month after we installed that system wich is not cheeap and was with warranty for 1 year. water from that filter started to taste like a grass. i called the company if they can come and check, they came changed the filters charged me another 140$ and after 2 weeks the water started to taste the same. it the worse company i ever deal with.they do not provide costumers with what they promise to you. the warranty does not mean anything. they will make you believe that its your falt that the water like that. not the filters they gave you. i recomend not to buy those filters from that company. it is a big scam.
