This filter works great and lasts a year for us. We have good well water but it has a small amount of fine brown sediment that stains everything from white clothes to toilets. This filter pays for itself by saving our stuff from staining. I'm glad our contractor recommended it.

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.

WITH OUR NEW OFFICE SHOP COMPLEX WE WERE HAVING SCALING ISSUES FROM THE INCOMING WATER COMPANY WATER DELIVERY. IT WAS CAUSING SCALING AND BUILDUP OF ALKALYN RESIDUAL CAUSING A DECREASE IN LINE PRESSURE AND SHUT DOWN OF SUCH THINGS AS OUR ICE MACHINE. SINCE THE INSTALLATION WE HAVE SEEN VERY LITTLE RESIDUAL BUILDUP OF SCALE. ALSO WITH THE ICE MACHINE, THE ICE SEEMS TO BE CLEARER PRODUCT THAN BEFORE. AT THIS POINT I RECOMMEND INSTALLTION OF THESE UNITS.

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!

Our water has two problems. It is hard and leaves a white residue and it is also high in iron which, if not delt with, begins leaving a red stain. The ICS-SIPK combination of filters take care of both nicely. The iron filter showed improvement almost immediately. The PolyHalt filter took a bit longer to show results but that is because it takes longer for the deposits in the water lines to clear. After a few weeks the results became evident. Our water tastes great and the white build-up and the red iron residue are not a problem. Changing the filters annually is an easy procedure and after the first time to learn the ropes is a matter of only about 20 minutes to accomplish. We are very pleased with the results.

A few years ago I switched from a water softening system to NUVO, but found that the NUVO did very little because I live in an area where I have a well. The company that services my well suggested I purchase Cascadian. The difference is amazing. The mineral buildup with which I was dealing on my faucets and shower heads has almost completely disappeared, and the water tastes just fine. So, no 50 pound bags of potassium or sodium, and no NUVO filters that were a waste of money. I'm obviously a fan of Cascadian.

I live on an island where the water is hard and tastes awful. I was wanting to put in a water softener but my plumber convinced me to use the Cascadian Water system with the ICS-STPK filter. I couldn't be happier. First of all the water tastes great, my fixtures are not sporting hard water stains, and taking a shower or bath is a soft water delight. I am awed by the gunk on the filters when I change them once a year. (Terrifying, actually!). I'm so please with this system, I added it to my rental house for my tenants. All is excellent!

Taste like pure mountain water. No weird hint of manmade additives. Pure as nature intended.

I love my water. It is clear, tastes great and doesn't stain anymore. I used to have a little bit of sediment that would plug the shower head and that problem is gone. My iron problems are gone too.

Once we installed the ICS-STPK, the mineral buildup in our plumbing has decreased very significantly. While cleaning all sinks, shower, etc is easier, it is the reduction in buildup in the toilet that is most noticeable, about 90% better. This has saved me tons of scrubbing, etc and I'm very happy about this. While the annual filter cost is substantial, I think it is definitely worth it.
