Take your water purification to the next level with the Phoenix Gravity POSTreat™ Steel Fluoride & Arsenic Reduction Filters. Designed as an essential specialised add-on, these elements attach directly to your primary carbon filters to remove over 95% of fluoride and arsenic from your drinking water—all while retaining the beneficial essential minerals your body needs.
Crafted with premium, non-leaching AISI 304 stainless steel housings, these filters eliminate the risk of microplastics or polyurethane leaching into your water. With a sustainable, eco-friendly refill system, you simply replace the internal FluoRid™ media every 4 months rather than throwing away the whole housing, making it both cost-effective and environmentally conscious.
