    Where does ICS 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

    It works flawlessly

    We installed our first ICS H2s filter. We put it behind a Nitro System that was randomly allowing H2s by. It works flawlessly. Thanks for the new ICS systems. We bought all 4 for our inventory.

    The sulphur smell and taste was completely neutralized by the filter

    We have had wonderful feed back from our customers. We installed one where the sulphur smell and taste was completely neutralized by the filter. It was so bad the odor could be detected all over the home when the water was ran. Right after I installed the filter I tried the water from the hose and could not taste the sulphur at all.
