A number of systems include the use of Far Infra Red Energy.

This is a completely natural form of energy that emanates from certain minerals, the most effective being the semi-precious gem, Tourmaline. Other minerals are used, often under proprietary brand exotic names, to enhance their perceived ability. Far Infra Red energy (FIR) has the ability to soften water, to negatively charge it, and to restructure and partially disinfect it into smaller molecular clusters which may assist in hydration of the body.

Most systems use FIR by including it in the replaceable filter.

Systems include Energizers, Jupiter Water Alkalizers, and some single pass magnetic systems.
