Clean and natural Soft Water System

A Natural Eco-friendly and Better Way to Soft Water

We get it

Salt-based ion exchange water softeners have been around for ages, but now there’s something better…

For the longest time salt-based ion exchange water softeners were the best available technology. They do a nice job of eliminating the common qualities of hard water (we know salt-based softeners, we’ve designed and built some of the best since 1994).

What we all didn’t know is till relatively recently is this; salt-based water softening is changing our environment, it is polluting our fresh water supplies. And there is no practical way to reverse the damage.

Did you know you are advised against watering plants with salt softened water because many plants can’t survive the increased levels of salt in the water?

The salty waste water problem is so bad that many governmental jurisdictions have banned salt-based softeners.

Besides the constant upkeep that is required for the salt-based softener system to work they don’t remove chlorine, sediment, or silicaNor do they protect against low pH or aggressive water.

We knew there had to be a better way.

And that’s why we created a whole new water softening technology:


Not only do PolyHalt systems soften water without the use of salt, they also filter out sediment and chlorine taste and odors.

What our customers
are saying

Before Cascadian, when my fixtures where clean of residue it would take about 3 days to cloud up and I could not remove the residue unless using some type of cleaning / polishing products.

With the Cascadian filter installed it takes about 2 weeks for any residue to appear and any residue wipes right off.  My clear glass shower doors clean up much easier.  I am very happy with this.

I called Cascadian Water and spoke to Jodi. She asked me a series of questions. Realizing that the set up I had was not standard, she shipped me a new casing and fitting, and then helped me to find a plumbing service that was responsive and had experience working with Cascadian Water systems.

Jodi and the team were all about ensuring that I had what I needed, and she went beyond the call of duty in finding a local expert to assess my situation.  Service and caring beyond the call of duty.
