Effective Eco-Friendly Water Treatment Made Simple

You've got serious water quality problems, we've got simple and effective solutions. Our ICS (Integrated Cartridge Solutions) line of water treatment systems take water treatment to a new level. ICS water treatment systems provide high quality water without salt, harsh chemicals, waste water or power in a small package with easy annual maintenance. Most waters can be treated with our ICS products. If you've got really big problems or need very high flow rates our more traditional automatic Cascadian Solutions will be the right treatment for you.

ICS Solution Benefits Include:

  • For municipal, community or well water
  • No salt or chemicals to buy and use
  • Easy Maintenance – simply change the cartridges in a few minutes. Filters typically last a full year before needing to be changed.
  • Systems are fully assembled and ready install and beginning in 2015 all filter housings will have a built in drain valve to make service even easier.
  • Easily install just about anywhere - no power or drain required
  • Compact space saving size - mount to wall or under counter
  • Large filters result in fewer filter cartridge changes and less maintenance

  • Mineral / Hardness Deposits
  • Orange, Red, Brown, Black and Blue Stains
  • Etching and Pitting
