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 Great tasting water PH dropped to normal range, chlorine is gone & Hard-water significantly reduced. Installation was fine we made a easy bypass and drain to help with future filter changes. Water is delicious and best part is we can take it from any tap in the house. Didn’t take long to see the difference on the test strips. After a week everything seemed to be settled and great. Only recommended change would be the black bushings that come with the system had a hard time to keep them from leaking. Had to purchase another set to finally get the leaking to stop.

Rated 5 out of 5 by from OptimH2O® Whole House Filter with Descaler & UV Performing as it should. We kept tropical fish and they died before we could transition from old filter system to Aquasana. Based on water testing kits since installation, our water is completely matching the best results on the test strips. The units sent to us by Aquasana were very well packed and protected. After units installed, everything works as per instructions and brochures. As advice, these units need 5 to 6 linear feet of space per photo by Aquasana. Our plumbers had 33 inches of space to work with and they did it and they were paid extremely well to do it. We have had whole house water filtration since moving into this house 38 years ago. Whole house is the only way to go and many benefits to the house beyond excellent tasting coffee.

Rated 5 out of 5 by from I absolutely love clean, pure water! The plumber did a fantastic job, and installed bypass valves as extra security. We purged the hot water heater, emptied the ice makers, power cleaned the washing machine and dishwasher. I told the plumber I wanted the "pretty" water everywhere. I can't even describe the multiple benefits-the coffee maker doesn't cloud up, the dishes are cleaner than ever, the soft water is silky (I forgot how lovely it would be.) Overall three thumbs up. I've bragged on the system to anyone who will listen.

Rated 5 out of 5 by from So far so good! Purchased this set up with the water conditioning system, UV protection and RO system under the sink about 2 weeks ago. Aquasana recommended a good plumber in my area that has installed about 100 of these which was very helpful. Installation took our plumber about half the day, and another couple hours for the RO system under the sink. Overall I am very happy with this system, water pressure decreased very very slightly but nothing even worth complaining about. The RO system under our sink has led us to not buy anymore bottled water which is nice as well. This system does not give that slippery/oily water feel like a salt water conditioner would which is fine because there is no backflushing and regeneration with this system (save money on your water bill). NO MORE TOILET RINGS! We have 4 toilets in our home so not having to scrub the toilets every week to get rid of the toilet rings was just icing on the cake!

Rated 5 out of 5 by from Overall Impression on the OptimH2O Whole House. Very impressed with the system and the quality of water. We not only have chlorine, but have chloramine in our water which is more difficult to remove. This system has also eliminated the sulfur smell. Since the plumbing was under the concrete slab, we had to route the piping through the attic.

Rated 5 out of 5 by from Water never tasted as good,or smelled better! The system was easy to install. Our shower, washing machine, and dishwasher use a lot less soap. The dish washer stays clean like brand new. We now have peace of mind that all contaminants are being removed and the UV system is killing any bacteria in the water. The water tastes delicious. Thank you.

User Q & A

Can a home owner install the system? Or, does a plumber need to do the install? If yes, what is the average cost to have a plumber do the install?

Asked by: Tom3
Thank you for reaching out to us! Yes, the system needs to be installed by a licensed plumber. We are the manufacturer and distributor but we do not have installation technicians in the field. We do work with a network of plumbers across the US who are familiar with and/or certified to install our systems. If you would like to know if there is anyone in your area, please email us at info@aquasana.com with your city, state, and zip code. We look forward to hearing from you.

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

We live on 5 acres and have a well. We have seen a white scale develop on faucets and in the dishwasher and fridge water tray. Probably hardness in the water. Will your system fix this problem.
