WECO Aqua-Titan light commercial reverse osmosis filter uses four stages of water filtration to create pure drinking water, ideal for residential use, medical offices, laboratories, schools, aquariums and hydroponic growing operations. The process starts by removing tiny particles like rust, silt and insect parts. This protects your family and prevents the filtration systems from clogging. Next, the water flows through activated carbon block cartridges. These compressed carbon block filters remove taste and odor-causing chemicals like chlorine, chloramine and rotten-egg odors. Chlorine disinfection process can create cancer-causing byproducts in the water. These carcinogens, called THMs, are removed by the carbon filters. The carbon cartridges also remove organic contaminants like herbicides, insecticides and industrial chemicals that seep into groundwater. The next step involves the reverse osmosis (RO) process. Here water is “squeezed” through a special membrane. Heavy metals, like lead and mercury, are removed while purified water passes through. The RO process also removes salts, fluoride, radon and benzene. The Aqua-Titan makes refreshing water the whole family will enjoy. Aqua-Titan filtration system is pre-assembled can be installed with simple hand tools. We recommend installation by a licensed plumber to insure adherence to all local codes. Routine replacement of the filter cartridges is recommended to maintain filter performance.


  • Commercial/Industrial drinking water purification
  • Hydroponic plant growing operations, Greenhouses
  • Large Aquariums
  • Breweries
  • Nursing homes, Health facilities
  • Laboratories (Aqua-Titan DI Models)
  • Ideal for anyone health-conscious and concerned about drinking water quality
