How it works

Our Salt-Free Water Softener utilizes Template Assisted Crystallization (TAC) technology to reduce scale. This process safely and effectively hinders scale buildup by reducing hard minerals into inactive microscopic crystal particles that can no longer harm you and your family.

1 Stage One

Sediment Pre-Filter

A sediment pre-filter is used to catch rust, sediment and silt before it passes through your pipes.

2 Stage Two

Salt-Free Water Softening and Descaling

Once water has passed through the sediment pre-filter it is softened and conditioned using TAC technology. This process alters the structure of the hard minerals that bind and form scale within your pipes and in your water. TAC technology reduces scale by and negates the need to add salt or chemicals to your water.

Get the Best Water for the Ones You Love

We take pride in our Salt-Free Water Softener and are happy to provide eco-friendly, salt-free softening technology for the benefit of the ones you love. You will never need to put salt or chemicals in your water to prevent scale buildup.

Less effective salt based water softeners demineralize water through the insertion of sodium ions. The replacement of these natural, healthy minerals can mean you are getting water that is stripped of beneficial nutrients. Our system benefits from TAC salt-free technology negating the need for added chemicals and salt.

Eco-friendly technology means that no harmful water discharge is flowed into the environment. Other competing salt-based softeners use a process of ion exchange that replaces the natural minerals in the water with sodium (salt). Because these systems are reliant on salt, multiple municipalities have banned the use of these types of softeners.

Salt Free Softening with TAC Technology

In addition to removing scale, stains and spots that form from hard minerals flowing through your water, Filter Butler Salt-Free Softeners also contain a technology that conditions your water naturally. Template Assisted Crystallization (TAC) softening technology physically alters the structure of hard minerals into a crystal structure. This structure prevents minerals from binding and building up scale deposits and is proven to reduce scale. 

The Filter Butler Salt-Free Water Softener comes with a
30-day satisfaction guarantee and a 6-year warranty.

The Filter Butler Water Softener system is easily installed with the help of a licensed plumber. Install the system where your water line enters your home – this is usually located where your hot water heater is located. System does not require electricity or back-flushing. The system comes with all the necessary instructions and installation components. We recommended installing it in an area that is free from extreme temperatures or direct sunlight and with access to proper drainage.

Maintenance: Your system will require minimal maintenance every 6-years. Just replace the two main filter tanks and you’re good to go! To replace the tanks just shut off your water supply with the provided valve, detach the two main tanks (top and bottom tanks), and replace them with the new Filter Butler softener tanks. The entire process takes just a few minutes.
