WECO is proud to present the PureT branded EZ Slim 5 stage reverse osmosis filtration system. EZ Slim is the ideal water purification filter for home, office, health clubs, juice bars, coffee shops or anywhere safe, fresh-tasting water is needed. The PureT reverse osmosis system uses separate individual stages of water filtration to create pure, refreshing drinking water. The process starts by pre-filtering the water through a sediment particulate filter. Prefiltration removes tiny particles that can get into the water supply. These include iron oxide (rust), silt, sand grains and insect parts. This filtering stage protects your family from drinking sediment and prevents the filtration system from clogging. At the 2nd stage, a granilar activated carbon filter cartridge filters chlorine taste and odor. Next, water flows through an activated carbon block cartridge. This compressed activated carbon block filter removes taste and odor-causing chemicals like chlorine, chloramine and rotten-egg (hydrogen sulfide) and musty odors. TThe carbon cartridge also removes organic contaminants like herbicides, insecticides and industrial chemicals that seep into groundwater. But that’s not all. The next filtration stage involves the reverse osmosis (RO) process. Tap water is “squeezed” through a special Thin Film Composite (TFC) semi-permeable membrane. Heavy metals, like lead, cadmium and mercury, are removed while purified water passes through. The RO process also removes salts, nitrate, fluoride, radon and benzene. The reverse osmosis membrane is NSF-certified and features outstanding efficiency. Other reverse osmosis filters can waste up to 10 gallons of water for every gallon of pure water made. Just like our own WECO RO systems, the PureT EZ Slim high-performance RO membrane produces only four gallons of waste water for each gallon of purified water. This saves you money, reduces waste water, conserves resources and helps the environment.
