The general concept with installation of your Aqua Energizer™ is to put your structuring device as close to the point of you as possible.
This usually means filters and any mineral treatments come first and the device last.*
However, if convenience or other reason dictate putting the structuring device first go ahead and do that as there is no hard science that proves the device needs to come last. The most important part is having structured water, not whether the device is one direction or another by a few feet.
*Water filters use chemistry to remove particulates from water. Structuring uses vortex spin, natural materials and sacred geometry to revitalize water. They function harmoniously with each other. There are no detrimental effects from using a filter and a structuring device together.
