Innovative Technology

SCM salt-free technology naturally and safely reduces scale buildup on internal pipes and plumbing without the use of harsh salt or chemicals. Learn more about SCM technology » Water Conditioners vs. Traditional Water Softeners

Scale and corrosion without SCM protection can build up in your plumbing and appliances.

Protect your home and appliances with an Aquasana Salt-Free Water Conditioner.

Innovative Salt-Free Technology

Scale Control Media uses water flow to naturally alter the structure of hard mineral ions into a crystal structure that prevents the minerals from binding and forming scale buildup. SCM salt-free technology is proven to reduce scale on internal pipes and plumbing. Unlike salt based softeners, Aquasana's Salt-Free Water Conditioner will not demineralize your water, harm your pipes with harsh salt, or put excessive amounts of sodium waste into our communal water supply.

Rated 5 out of 5 by from At last one unit to do all. Thanks for introducing one Whole House unit that removes PFOA/PFOS. I have installed many Rhino whole house filters plus Undercounter RO units for cooking and drinking water. Now you offer one unit that does it all. Others companies had whole house RO systems that were prohibitily expensive. This is perfect and affordable for my Handyman Business customers.

Rated 5 out of 5 by from Excellent system, no salt! We are enjoying the system. It pays to shop around for a plumber, the quotes ranged from $4,300 to $600. The plumber I choose had experience in installing Aquasana systems.

Rated 5 out of 5 by from happy safer water drinker from the time we were able to start using it, the chlorine water smell was gone from everything in the house! Install was horrible as aquasana rep said it should take 2-3 hours for our system and RO to be installed, but it too a plumber over 5 hours to do which was WAY more $ than desired and expected and stressful. Also nervous about having to change the filters due to placement in crawlspace so hoping to figure it out ourselves versus calling that plumber back. But, the water from all the faucets has no odor now and we feel like it is cleaner contaminent wise than it was prior!

Rated 4 out of 5 by from Not as great as touted The filter was easy to install in about 2 hours. The quality of the water does not seem improved based on the amount of scale and cloudy residue left on dishes and inside sinks/showers/dish washer/washing machine.

Rated 4 out of 5 by from Great Filter The filter system works very well. I pull from a well in central Washington state in farm country so the water from the source is not desirable unless filtered. the charcoal filter, pre filter, post filter and UV light made my water completely drinkable and odor free. The install was basic and simple. if you have ever plumbed a water softener you can do this. however, I am not entirely convinced the descaler works as advertised. I think I will be adding a salt based water softener to this system due to the scale still depositing on everything.

Rated 3 out of 5 by from Better. but did not solve problem Product arrived on time and installation was start forward. I had a mild to medium hydrogen sulfide problem (egg odor) before and after installation. I’m not sure if treating for things I don’t have in my water and not treating effectively what I have in water. My water was not that bad based on laboratory testing but still have some odor. I’m working with technical staff to resolve so will do follow up review.

Rated 1 out of 5 by from This system has NEVER worked in my home After spending $3k for the filter, salt-free descaler, and uv-light plus and additional $900 to have it installed by a plumber - this system has never worked. Aquasana sent a new filter - water still will not move through the large optum H20 filter. The PSI in my home is high enough and my pump works great! But, the aquasana system has been on bypass the entire time it has been installed in my home. My water is brown, I'm $4k down and I have to buy drinking water. The assistance I received in November was less than helpful and the emails I have sent requesting assistance have gone unanswered. The install instructions don't have enough detail - what should the PSI be set at?  Is it okay to have a variable jet pump or is a different pump required?

Rated 1 out of 5 by from Worked great for around a month Had filter professionally installed. There was an initial slight drop in water pressure which was expected. Within 2 months the water pressure was so low due to the filter that we could only run one shower and nothing else, not even a dishwasher or washing machine. Even the one shower had extremely low pressure. Replaced the filter and same thing. Filter is very expensive to replace monthly. Have had to bypass the filter and no longer use it.

Do these systems remove flouride?

Asked by: kmcd
Hello,   Thank your for your interest in Aquasana. The Whole Home system does not remove fluoride or arsenic. Both require Reverse Osmosis to be removed/reduced from water. We do offer a Point of Use Reverse Osmosis for your drinking water, and many of our Whole Home customers purchase it in combination.   You may read more about our Reverse Osmosis system at: https://www.aquasana.com/drinking-water-filter-systems/reverse-osmosis-claryum If you are interested in a system, please call 866.662.6885 or e-mail sales@aquasana.com and a representative will be happy to discuss your needs and options.   Thank you,   Aquasana Support
