Many different filters can work together to provide you with the cleanest and freshest tasting water. Sediment filters remove dirt, rust and other sediments. Carbon filters filter chlorine and other harsh chemicals. A RO membrane can handle much tougher contaminants.
Depending on your chosen RO system, these multi-stage filters can work together to provide for your every water needs.
