Frequently Asked Questions

Where does the ICS system go in my home?

Where it can fit, and where it can easily get access to your home's water source. This is typically a garage, crawlspace, or even a closet. If you have questions a plumber would be able to help you find the best spot. During maintenance you'll need to fit a bucket and have enough space to turn the sump wrench which comes with your system

How often do I replace the filters?

Most people replace their filters once per year, or sooner if they start seeing issues with their water again. Learn about water issues here

Great filter that takes the iron out of our water

My unfiltered water rusted my washing machine and stained the toilet and tub.
The process has been corrected.

Always Clear

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.

Thanks for the awesome review, John! We're thrilled the ICS-SIK filter keeps your water clear for a year. The brown pre-filter is proof it's working hard! We're always here if you need anything.
