Backwashing Whole House Carbon Water Filter

Click Here if you are looking for Cartridge-Based whole house carbon filters.

Our automatic backwashing carbon water filters give your entire household cleaner, better tasting water with less chlorine, taste, odors, and contaminants. They also give you a healthier shower experience if your shower water contains Byproducts of Chlorination such as Trihalomethanes and Haloacetic Acids at unhealthy levels.

Backwashing Carbon Filters save you money on carbon filtration. These premium whole house carbon filters feature the famous Fleck 5600 Mechanical Timer (3/4” Inlet/Outlet) and Fleck 7000 Digital Timer (1” Inlet/Outlet) control valves for great performance and reliability, and premium (made in USA) activated carbons by Calgon Carbon. We use several types of high quality carbon, listed here. Also, properly sizing your whole house carbon filter is important, so we've created a must-read guide that helps you do this.

Important: Click here for installation instructions if you have a water softener OR a Chlorine Injection System.

For specific contaminant problems, working with catalytic carbon, or if you need higher-capacity systems, call us at 210-568-3628 for technical assistance.
