and harmful substances, multiple water purifications, retaining minerals and and trace elements, with nice water quality. 5 layers design, different layer made of different material, layer by layer filtration make the water more pure.Two types optional, you can choose water filter system or filter only according to your demands.Filter:5 layers design, different layer made of different material, layer by layer filtration make the water more pure.The first layer and the third layer are propathenecotton, effective filtration of 5μm sediments and rust in water, large filtration area and dirt absorption.The second layer is compressed activated carbon layer, effective adsorption of water color and odor, residual chlorine, organic substances and other harmful substances, compressed activated carbon and a high dirt-absorbing mesh structure makes it has double filtration performance.The fourth layer is ultrafiltration membrane layer, which has ultrafiltration micropores of 0.01μm, which effectively hold suspended solids greater than 0.01μm in water, colloids, particles and other impurities.The fifth layer is post loading silver activated carbon filter layer, deeply remove bad smell, cleaning residual chlorine, effectively prevents secondary pollution of purified water, makes drinking water more hygienic.Specifications:Name: Water FilterMaterial: ABSType: machine, filter (optional)Applicable water pressure: 0.1-0.3MpaWater flowrate: 3L/minWorking temperature: 5-45Item size:Filter length: 7inchMachine size: 255* 135* 310mm/ 10.04* 5.31* 12.20inPackage size: 330* 280* 150mm/ 12.99* 11.02* 5.91inPackage weight: 1800g/ 3.97lbPacking List(machine):1* Water Filter MachineORPacking List(filter):1* Water Filter
