RO systems are the best way to remove most contaminants from drinking water, including Fluoride.
4 stage RO systems are the most common systems used with the 5 stage containing an extra sedment filter for known dirty water supplies. Unless asked, all our membranes are TFC ( thin film composite) as these are superior to the other membranes in several ways.
We do vary the carbon cartridge depending on whether the location to be used is rural or urban, with a higher chlorine removal capacity cartridge being used in urban supplies.
All urban systems also include a 600 kpa pressure limiting valve to protect the system from overly high water pressure and water hammer.
