Air Purification Cartridge & Water Filter Shelf Life

Core Issue:

  • What is the shelf life of the air purification cartridge?
  • What is the shelf life of the water filter?
  • Is there an expiration date for an air purification cartridge?
  • Is there an expiration date for a water filter?


Sub-Zero air purification cartridges & water filters do not have a shelf life.

As long as water is not run through a water filter and the air filter is not plugged into a unit, there is no expiration date or "use by" date.

Filters are available for purchase through Sub-Zero’s Accessory Store.
