The SLOW PHOS Salt-Free Water Conditioner is designed to protect your home appliances and plumbing from the adverse effects of scale buildup. Extend the life of your water heater, washing machine, dishwasher, and other appliances without adding excess salt waste or chemicals into the environment. Eliminate that filmy residue that causes staining and spotting on tableware, clothing, shower heads, and faucets.
Aquasana uses innovative SLOW PHOS salt-free water conditioning technology to naturally descale your water and protect your pipes from corrosion without the use of added sodium. As its name implies, SLOW PHOS uses food grade polyphosphate beads engineered to dissolve at a controlled (or "slow") concentration to effectively target scale producing hard mineral carbonate crystals including calcium, magnesium, and barium (Ca, Mg, and Ba).
SLOW PHOS technology works by altering the ionic charge of these carbonate crystals to reduce their attraction to one another in your water. By altering their ionic charge, hard minerals will no longer clump or pack together and create scale (Ca, Mg, and Ba buildup). In addition, SLOW PHOS phosphates act as a protective barrier in your plumbing to protect from pipe corrosion. Unlike salt-based water softeners, Aquasana SLOW PHOS technology will not demineralize your water.
Aquasana's SLOW PHOS Salt-Free Water Conditioner is low maintenance, and does not require electricity, drainage for wastewater, or heavy bags of salt to lug around.
