ICS-HK cartridge filter replacement kit

The ICS-HK cartridge filter replacement kit is designed specifically for the Cascadian ICS-H filter system and engineered to improve hydrogen sulfide (rotten egg) taste and odor problems from all the water for every use in your whole home or business. It is an excellent choice for well water. 

  • Reduces and often completely eliminates foul smelling H2S (rotten egg) odors
  • An excellent pretreatment for any of our other systems when H2S exists in well water

For the best treatment we recommend following the ICS-HK with the ICS-STPK.

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.
