Ion Exchange Water Filter - Automatic Coffee Maker

Possible Solutions

What does it do?

The Ion Exchange Water Filter removes many contaminants from your water. If you have filtered water the Coffee Maker can be used without it. If you choose to use one, it is important to change it regularly to prevent impaired taste. The filter will process 25 gallons of water or about 60 full carafes.

The Ion Exchange Water Filter has carbon, to reduce chlorine and also softening resins, to reduce the hardness of the water. The ion exchange process works just like a water softener in your home.

How to replace the filter?

  1. Soak in cool water for 10 minutes, before the initial installation.  This only needs to be done before first use. Initially, soaking the filter removes the extra charcoal particles/flakes and removes the grayish color.
  2. Install the filter
  3. Brew one full carafe of water (without coffee) to remove carbon filter particles that could impart an off taste to your coffee.
