Aquasana SimplySoft is better than just a softener. It won't demineralize your water by chemically removing minerals from your water nor will it put excess salt waste into our environment.

Gently and naturally conditions water using innovative salt-free water softening SLOW PHOS technology designed to prevent scale formation and protect from corrosion.

Easy replacement of water softener cartridges without the need for a plumber. Cartridges need to be replaced every six months or 50,000 gallons.

SLOW PHOS Salt-Free Water Softening Technology

More than just a softener, Aquasana SimplySoft uses innovative SLOW PHOS salt-free water softening technology to naturally condition 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 SimplySoft SLOW PHOS technology will not demineralize your water nor will it negatively affect the environment by adding excessive amounts of sodium into our communal water system.

Rated 3 out of 5 by from Not as good as salt-based system I was excited to find a system that I could install in an apartment. I had a salt based system in my home, so we were not used to hard water and needed to get one in ASAP.|A had to re-do the threaded connections at the filter since this tended to leak a bit. Use a LOT of TEFLON if you don't want to cut pipe again.|Have it in service almost a month now and still waiting for the softness. Wife just

Rated 4 out of 5 by from Saved our water! I purchased the Aquasana Simply Soft Water Filter to enhance the quality of our well water. The filter is effective in removing the minerals from the water output for several months. The filter, after use of several months, restricts water flow and pressure. However, the cost of the replacement filter is prohibitive to replacement as often as needed.

Rated 3 out of 5 by from Doesn't perform as I had hoped it would I like not having to haul salt bags down the steps, but this salt free softener doesn't seem to soften the water like water softener's that use salt do. I still get hard water stains on sinks and tubs. Maybe my water is too hard for this type of system. It's better than no conditioner, but it doesn't perform like I hoped it would.

Rated 5 out of 5 by from Great Salt-Free Water Softener This salt-free water softener provides a very effective solution to hard water provided by city or community well providers. The results are truly outstanding. The product is easily installed and negates the need for the addition of salt products on a regular basis. It works very well and lasts at least a year.

Rated 5 out of 5 by from Great products The effect on water mineral content, clarity, smell and taste is instantaneous and profound. No more bottled water and no more spots on the dishes coming out of the dishwasher.
