All MXL systems can be installed either on the countertop near your sink or underneath your counter with a faucet attachment. Which one should you get? Both provide the same high-quality water. The under-counter Life Ionizer comes with a beautiful faucet that is available in a variety of finishes so that you are able to match it with your kitchen’s aesthetics perfectly. Under-counter Life Ionizers free up counter space and you can control the unit under the sink with the electronic faucet. We always recommend purchasing your system with an undercounter attachment if your kitchen space permits, which it should as the unit and filters feature such a small footprint. Select under-counter and your desired finish to get an under counter unit, or simply select overcounter for the standard MXL countertop setup.
