  • Filter system and leak detection

    Easy to install, we do ours every 2 years; with an exception if the city works on the pipes and causes debris in the water lines. I put a plastic rectangle container (like you buy to put pantry items in) under mine with a water sensor in case of a leak in any of the filters or lines.

    We have been very happy with the 14-Stage Radiant Life under the sink water filter. We use it not only for cold drinking and cooking water, but also have it hooked up to an Insta Hot which works great for hot drinks (coffee etc). The quality and taste of the water is unmatched.

    This kit contains the exact set of filters needed and the online video is always a good reminder how to perform the replacement. My family frequents the filter spigot several times a day to fill their personal water bottles. Clean filtered water is very important around our household.
