Refrigerator - SmartWater, SmartWater Plus, and Water by Culligan Water Filters

GE Appliances offers ice & water filtration in many new and older refrigerators. The refrigerator water filters use carbon media to reduce chlorine, odor, lead, cysts, and improve taste.

The filters are easy to replace with no special tools required; there is no need to even turn off the water.

In the past, refrigerator water filters MWFA/MWF/GWF/HWF & GSWF/MSWF have been labeled under the following names:


MWFA/MWF/GWF/HWF SmartWater & SmartWater Plus Filtration Systems

  • Refrigerators with SmartWater Plus filtration systems use the SmartWater filter (MWF/GWF/HWF) and have a filter indicator to remind you when to replace the filter.
  • Refrigerators with SmartWater filtration systems use the SmartWater filter (MWF/GWF/HWF) but do not have a filter change reminder.
  • SmartWater filters have a Class 1 rating for taste, odor, chlorine and particulate reduction. The filters are manufactured in Minnesota.
  • The MWF filter has been replaced by the MWFP, which is the improved, replacement version of MWF. The label on the MWFP will read "MWF". 


Replacing the SmartWater Filter


GSWF/MSWF SmartWater Filtration Systems

Some model refrigerators (Top Freezers w/Internal Water Dispensers & Bottom Freezers) have a cylindrical style SmartWater filter, GSWF or MSWF. This filter is not interchangeable with the MWF/GWF filter. The GSWF & MSWF are not interchangeable.
