We are excited to offer a system that utilizes a unique filtration combination that performs like a Reverse Osmosis system but still retains essential minerals in the water. Most filtration systems that are able to reduce contaminants to the level of micro filtration also remove the minerals from your system. Minerals in the water, such as magnesium and calcium, are essential to the body's well being and health. Studies have shown that when minerals are removed from the water you must remineralize your system and drinking demineralized water will actually cause the body to lose these essential minerals. The water from the CeraGuard ultra filtration system retains the minerals essential for your health as well as reducing contaminants. The mixed carbon bedded filter and multi-media bedded filter reduces unwanted contaminants such as bacteria, lead, VOC's, chlorine taste and odor, pesticides and much more. Overall, we found the CeraGuard system of exceptional quality and is fully designed to provide great tasting and healthy water.
