What it Takes From Your WaterEFF-6007A_33op

The way that the refrigerator water filters work to remove contaminants is by activated carbon.  This is a type of carbon that is incredibly porous.  Because of this, it has a surface area that is increased and this allows for it to be extremely adsorbent. The difference between adsorbent and absorbent, is that instead of the dissolved solid, liquid or gas being drawn into the carbon, it will instead stick to the surface of the carbon.

The process of filtration starts when the water comes into the chamber of the filter from the line that goes into your fridge.  As the filter fills up with the water, that water then goes through a chamber where the activated carbon is located.  The carbon will then act as if it were a magnet and attract any of the undesirable contaminants that might be in the water.  This includes mold, bacteria, asbestos and more.  It does this while leaving the beneficial fluoride alone.  All of the materials that are unclean and unwanted are then held on the carbon while the clean water comes out to you.  The overall result is crystal clear, clean, great tasting water that your whole family can enjoy.

The P4RFWB filter is incredibly easy to install.  If it has a push tab you will:

  • Push the tab to release the latch and open the housing
  • Turn the filter counterclockwise to release and remove it

If it has a pull tab you will:
