Does Water Need to Be Tested Prior to Choosing Treatment?
Does Water Need to Be Tested Prior to Choosing Treatment?
Everyones water source is unique, getting your water tested can give you a blueprint for your treatment
Why Should I get My Water Tested?
Why Should I get My Water Tested?
If your water comes from a private unregulated well it is very important you have your water tested to determine what problems need to be fixed and some of the major treatment enemies. If you get your water from a private well please purchase a WSK and allow us to test your water. We want to test your water even if you've had your water tested by a laboratory because we test for things typically not tested for by labs because we're looking for enemies. If you have lab test results please include the results along with your water sample.

PolyHalt® Tech
After 30 years in the water filtration industry, we arrived at PolyHalt® because it was the simplest, most natural softening mechanism we’d ever come across, particularly compared to the highly complicated salt-softeners we’d manufactured before.

Let customers speak for us
A+++++
Very helpful and responsive folks! Thank you!
Only the best
This is our 3rd year for filter replacement. This time we purchased the yearly replacement. Our filter system makes all the difference in the water quality!
Much better
Our water tastes so much better with our new system online!!! Highly recommend
Feel better using the Cascade water and deionizing filter system
cascadian water sent us the new filter and arrived in 2 days so very fast service. We wish we started to deionize and filter our water sooner. We feel better that the filter helps to protect our body and appliances from getting clogged up with mineral deposits.
Attentive and friendly
We recently moved into a house with a Cascadian Water filtration system, and their team has been super helpful in identifying the system and getting a new filter ordered for us with a quick turnaround. They're attentive and friendly and send the product in a super timely manner!
Very happy with this product
This is some of the best money I've ever spent. Our harder, high in iron H2O tastes great now, right out of the tap. Excellent customer service at Cascadian as well. I'm beyond pleased that we went with this product. Myself and my family sincerely thank all of you at Cascadian.
Great water filter for hard California water
My daughter recommended the Cascadian water filter and after reviewing the other systems on the market and available around San Diego I concluded the Cascadian water filter was the best for me. Our water is extremely hard down here and now the water in my home is perfect and soft!! We can easily tell the difference, in the taste, after washing our hair, etc. The system was easy to install (I did have help from a friend/plumber) and once it's turned on you just walk away and forget about it until next year when the filter needs to be replaced. No noise, no electricity needed, easy to maintain and service. This is a great system for my home. Highly recommended.
Best decision ever!
We recently built a house here in Chelan WA and decided to put a Cascadian Water filtration system in our home. Best decision ever! It has helped make our well water the clearest, best taking water I have ever had! Their customer service folks are responsive and helpful as well!
I highly recommend their products!
Simply The Best, Better Than All The Rest
I'm not given to writing reviews since every time we purchase anything the nagging to do so begins. But this review I want to write. Since moving to New Mexico 15 years ago I have purchased various water softening systems: salt, potassium, citrus and a few electromagnetic devices that attach to the pipes. None of them were to my liking. And then I discovered Cascadian Water. I was able to keep the housings from my last system, the NUVO, which was useless, and just replace the cartridges with Cascadians. What followed was more than surprising. There was a definite change in the quality, the feel, the taste of the water, as well as the minimalizing of deposits on everything that comes in contact with water. I replace the cartridges once a year which takes a very short time and little effort. And an important factor is Cascadian is eco-friendly. I recommend Cascasdian Water without any reservations.

No Slime, Just Happy Skin!
No more slime! My skin feels wonderful. We live in the desert with salt systems in almost every house. I'm so glad we are fortunate enough to have our polyhalt system.
Easy Ordering and Replacement
I've had my cascadian filter for 3 yrs now, replacing the cartridge yearly. I no longer get my faucet strainers plugged with sludge. All water appliances have no water issues. Drinking the water right from tap with no issues. Excellent Product and replacing filter is fairly easy. Totally recommend cascadian and customer service is top notch.
Seeing is Believing: Proof of Powerful Filtration
When we change our filters, there's a thick layer of reddish-brown muck around the filter so we know the filtration system is doing it's job extraordinarily well. I wouldn't want to drink or use the water without it!
5-Star Service: Fast, Reliable, Exactly What I Needed!
Excellent, super fast service and delivery. I believe it came overnight! Way faster than I expected. The filters are large, fairly expensive, but it is what I needed. 5 stars!
Orange Stains Gone! This Filter Saved Our Fixtures
The water filtration system works extremely well. Our Well has heavy minerals which caused our sinks, tubs and toilets to turn orange. After installing the filters, problem is fixed. Filter replacement is simple.
Seven Years of Crystal-Clear Water
We’ve been using cascadian whole house filters for seven years and couldn’t be happier with the results. Changing the filter cartridge is simple and straightforward and I’ve never had a problem. We’re still amazed at the before and after results as evidenced by the photo!
