Non-Sub-Zero Water Filters

Core Issue:

  • Can Sub-Zero water filters be replaced by non-Sub-Zero filters?
  • Use a different brand's water filter
  • Will use of a third party filter cause performance issues?


If non-Sub-Zero water filters are used in units with built-in water filters, water filtration may be poor or other product problems may arise from the use of filters not specifically designed for our products.

Contact a Factory Certified Parts Distributor to order water filters.
