Answer:

Water Filter Part Numbers

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.

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.*

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.
