Know Your Fridge Filter: GWFA |

For a powerful filtration tool that eliminates harsh impurities from your tap water, look no further than the GWFA refrigerator water filter.  Designed as an aftermarket replacement for the GE MWF filter, this filter can fit into many popular brands and models including refrigerators by GE, Amana, Hotpoint, Kenmore, and others. Unfiltered tap water that enters your home is susceptible to contamination from a variety of sources. Never worry about drinking dirty water again when you install a new GWFA fridge filter in your home to produce better-tasting, clear water for beverage making and healthy ice.

How to Install the GWFA Filter

The installation process for the GWFA filter is fairly simple and can be done in minutes. First, locate the filter cartridge typically found in the upper right corner in the back of the refrigerator compartment. The filter cartridge should be replaced once the replacement indicator light turns red or if the flow of water to the dispenser or icemaker decreases.  For refrigerators without an indicator light, a good measure to go by is every 6 months.

  1. Remove old filter cartridge by grasping and turning to the left about 1/2 turn
  2. Fill the replacement filter with water from the tap to allow for better flow immediately after installation
  3. Place the top of the new cartridge up inside the cartridge holder
  4. Slowly turn the filter until the filter cartridge stops. Do not over tighten. As you turn the cartridge it will automatically raise itself into position. The cartridge will move about 1/2 turn
  5. Run water from the dispenser for 3 minutes (about 1-1/2 gallons) to clear the system and prevent sputtering
  6. Press and hold reset water filter button if your fridge has one

How Does the GWFA Work?mwf filtered fridge water

Inside an inner chamber of the GWFA replacement filter, there is a chamber filled with an extremely porous form of carbon called “activated carbon.” This substance has an increased amount of surface area that makes it an effective filtration tool at capturing and holding onto undesirable particulate.  This is what gives the GWFA water filter its filtration power.

As soon as water enters the filter, the activated carbon begins to work its magic.  Once water comes into contact with the filter block, the carbon begins finding impurities in the water and holding onto them as water is allowed to pass through.  The now clean water is then pushed back up out of the filter free from contaminants.  After this seconds-long process, crystal clear drinking water is then ready for consumption.  Now you can enjoy better-tasting, healthy water at all times.

Why Your Filter Needs to Be Changed

Although the GWFA filter is an excellent filtration tool that can safely provide your home with crystal clear tap water, the sad fact is that it won’t last forever.  After continual use, water passing through the filter can cause the inner carbon in the filter to degrade.  This makes the activated carbon lose its efficacy and can lead to a drop in water quality and even potential health issues.  You can prevent this from occurring by changing your filter cartridge when the indicator light on your fridge goes off.  If you do not have an indicator light, your filter should be changed at least once every six months so that your home is always provided with clean, safe drinking water.
