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 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.

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!

Hi there, I am interested in a unit that reduces both chlorine and fluoride. Ive seen the Data Sheet for the under sink model OptimH2O and it states it removes chlorine and fluoride. The Whole Home model does not mention fluoride.
