Product Performance
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.

Exactly as Needed
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.
