- The Alto 600GPD system passes the water through 5 stages of filtration using reverse osmosis technology, which filters down to a level of 0.0001 microns. - The 5-stage filtration reduces pollutants from the water such as sand, particles, rust, chlorine, heavy metal scale, pesticides and a wide variety of bacteria and germs. - The system includes an innovative internal pump and a high-volume membrane that allows a powerful flow of up to 1.5 liters/minute. -Possibility to hold a tank that allows a flow rate of up to 3 liters/minute. -Extremely low drainage ratio of up to 1.5:1 (about 80% savings compared to a normal water filtration system). - LED screen shows the remaining life of the filters. -Quick change filters, close the water supply, half a turn and the filter is outside, without the use of special tools. -Significant silence compared to other systems with a pump. - Dimensions: width x height x depth 41 x 42 x 21 cm.
