Let customers speak for us
My water filter replaced an old water softener that had been disconnected by the previous owner of my home. I live in eastern Idaho where the water is pulled from an aquifer and is mineralized needing filtration. This filter does its job and is easy to change the filter element annually.
I have a plumber replace the filters once a year. I have one set I keep on hand for the replacement and purchase a new one to have on hand. I live in an area with hard water and this filter cleans the water before it flows throughout the house. The water tastes clean.
I have been using these filters for 4 years. Being on well water isn't bad but when I change out the filter I am glad I have this product , no stains or water spots in the house. I recommend!
This year Cascadian have updated their subscription program. Because the timing of this update was precisely when our subscription was due to shipped, we wound up with two sets of filters arriving a day apart. The process to send one back was handled adroitly by Cascadian and could not have been easier. Thank you, Cascadian, for such a fine job.
I have not installed the most recent purchased filter. This would be the 2nd replacement. The original and 1st replacement did exactly what we had hoped for and that was provide us with soft water for showers that we have been used to for several years! It works great and lasts longer than advertised.
The filter works for a year without fail. The pre-filter removed during the exchange is always brown and we are grateful that the filtration system works so well. I couldn't imagine having no system.
We moved into our home in Gig Harbor six years ago. We had our water tested since we were on a private water system. We then installed a Cascadian Water Filter. The system made a difference in the color and taste of our water. Changing the filter annually is quick and easy.
Replaced old salt water treatment system with the Cascadian ICS-TP system in 2017, and we're extremely satisfied!
The complete system takes up less than a third of the space of the old system, it's much easier to replace the filters than making a mess with the rock salt, their video providing step by step directions of replacing filters is outstanding, the staff is experienced and helpful, and the water is cleaner and softer resulting in less hardwater buildup of our faucets.
With what we've experienced, we'd choose the Cascadian ICS-TP system 100 times out of 100 over ANY other system!
We no longer have to use a pitcher to filter our drinking water, our coffee tastes better, our showers are not soapy-feeling, our clothes are cleaner in the washer, and our dishwasher is doing a much better job!
Installation was fairly easy, and I did not have any issues.
The community well water at my get away house was safe but incredibly hard and tasted terrible. The filter system makes the water tasteful and refreshing. The annual filter change is easy and takes less than 30 minutes. Highly recommended.
Great water filter that filters out chlorine, makes water softer, and is changed once a year. Easy maintenance, reliable, long lasting, and inexpensive. Highly recommended!
