Answer:

To determine which filter is needed, enter the unit serial number into the Sub-Zero Water Filter Finder.

• The serial number of the unit is required to look up the appropriate filter.
• Refer to Sub-Zero Serial Tag Locations for help with finding the serial number on the unit.
• Refer to Sub-Zero Does Not Have a Water Filtration System for a list of units that have a water filter and units that do not.
  • See also, Water Filter Information.
• For units between serial number 4116297 and 4134313, see the part number on the current filter installed. It will be one of the following part numbers: 7005017*, 7009931*, 4204490, or 7023811.
• Some models have one-prong water filters. Some models have two-prong water filters.
  • If the current filter has two prongs, the original replacement part was 7005017 or 7009931. These part numbers will no longer work.*
• To order new water filters:
  • Order replacement water filters from the Sub-Zero Accessory Store or from a Factory Certified Parts Distributor.
