How it works

Our salt-free water softener works by preventing hard water minerals from bonding together to form scale. It uses a special media to transform these minerals into tiny crystals that can't stick to pipes or appliances. This process protects your plumbing, extends the life of your water-using appliances, and improves the taste and quality of your water without the need for salt or chemicals. Our salt free TAC media is tested and certified for performance.

For three decades, our tanks have set the standard with a seamless high-density polyethylene liner for lasting strength and a leak-free engineered polymer inlet, all wrapped in a protective neoprene cover to ensure a lifetime of worry-free performance.

Our Salt Free Water Softener Prevents…

Scale buildup in pipes, appliances, and fixtures

Reduced water flow caused by clogged pipes

Reduced efficiency of water heaters and appliances

Damage to water-using appliances due to hard water deposits

Spotting on dishes and glassware

Dry, itchy skin and hair caused by hard water minerals

Jordana - Scottsdale, AZ
Not only has it helped eliminate some of those mineral deposits around my showers and sinks, but it hardly takes up any space in my garage and it has been so easy to maintain.
Sarah M - Scottsdale, AZ
"The Whole house water filter for the house is great. It is very convenient to use super easy to maintain. The water quality is just like bottled water now at every tap. I like it a lot!"
Ron M. - Ventura, CA
"The pre filter after about three months you can see how black it is.
I highly recommend especially if you have really hard water like i do.
You need this system."

A three-year investigation by the EWG of the country’s drinking water found that water flowing to about 85% of the population contains 316 contaminants – over 60 percent of these have no safety standards and are not regulated by the EPA.

Easy Installation

Our Two Stage Process

Stage 1

A sediment pre-filter with a 5-micron rating efficiently captures rust and debris from water sources. Its design prevents these larger particles from causing clogs or damage to plumbing and appliances. Replace the pre filter inside the blue housing every 8-10 months.

Stage 2 & 3

2. Mineral Transformation As water flows through the Filtersmart system, it passes over the TAC media. This media is embedded with tiny, specialized "templates" that attract hardness minerals, specifically calcium and magnesium, which are the primary causes of scale buildup. When calcium and magnesium ions come into contact with the TAC media, they are converted into microscopic crystals. These crystals are formed directly on the media surface. Importantly, this process doesn't remove the minerals from the water but changes their structure.

3. Formation of Stable Crystals

The microscopic crystals that form are stable and remain suspended in the water. Because of their new shape and structure, these crystals can no longer bond to surfaces like pipes, water heaters, or faucets, which is how limescale typically forms.

As the water continues to flow through your plumbing system, the suspended crystals travel along with it. Since they are unable to adhere to surfaces, they effectively prevent scale from forming in your pipes and on your appliances.

FAQs

How Large Are The Tanks?

Our 1-3 Bath 12 GPM systems uses 9 x 48” tanks and sits about 52 inches
tall, including the valve head. The 4-6 Bath 15 GPM system uses 10x54”
tanks and sits about 58 inches tall. For single tanks, we recommend
20x10” space. For our combos, we recommend a 30x10” space.

What Are The Tanks Made Out Of?

For over 30 years, our industry-leading tanks have set the standard for durability and performance. They feature a one-piece, seamless high-density polyethylene liner for strength and longevity. 

Includes an encapsulated, leak-free engineered polymer inlet, ensuring consistent, reliable operation. Unmatched strength and durability wrapped in protective neoprene cover, our system is designed to provide you with a lifetime of worry-free performance.

Does The System Work For Well Water?

Yes. However it does not remove iron, hydrogen sulfide or manganese. It should be pre treated prior to our salt free systems if you have this in your well water.

How Often Do I Change Out The Pre-filter?

The sediment pre-filters (inside the blue housing) need to be replaced every 8-10 months. This can be done by any homeowner.

Who Installs The System?

Anyone with basic plumbing skills can easily install our systems. If you don’t know someone with basic plumbing skills, any local plumber will have no problem with the installation. If you need help finding a plumber, you can contact us to see if we have local plumbers in your area.

Where Is The System Installed?

Our systems are typically installed at the point where the main water line enters your home. This ensures that all water distributed throughout the house, including taps, showers, and appliances, is filtered. The filter is usually placed in a basement, utility room, or garage, or outside where the main water supply enters the home.
