The XERO Pure ATOM features a thorough three-stage purification process. First, water is filtered through the carbon filter to remove large particles. Next, it goes through an RO membranes to significantly reduce contaminants. Finally, the water is purified in a DI housing, achieving a TDS level below 10 ppm. Although the DI tank is smaller, it performs the same function, though you may need to replace the resin slightly more frequently.
Filter changes for the XERO Pure ATOM are straightforward and non-proprietary, allowing you to order your filters from a local supply store. Regular filter maintenance ensures optimal performance and keeps your ATOM running at its best.
