A 100% natural technology which combines our Zeoadsorbe®, our patented blend of natural zeolites, which provide triple-action filtration while preserving the water’s natural mineral content, ION-EXCHANGE capacity and a water structuring vortices. This unique design gives Zest filters their exceptional ability to remove harmful substances from water.

Is installing the filter difficult?

Soon, we will list installers on our website who join our partnership program to provide professional installation with a warranty. However, if you are handling a DIY installation, full downloadable instructions are available for the initial setup. If you’d like to install the set yourself, you can watch our installation video at the following link
