FREQUENTLY ASKED QUESTIONS
Q. How long does it take until the bottle has absorbed 100% of the oxygen?
A. Depending on the amount of wine remaining in the bottle the times vary, but in most cases oxygen is removed in less than 30 minutes.
Q. What are the ZOS Cartridges made of?
A. ZOS cartridges are contain a patented, non-toxic, USDA food grade material that absorbs all of the oxygen from an open bottle of wine.
Q. How long do ZOS Cartridges last?
A. Because the cartridges work by absorbing oxygen, it is important to limit the cartridges’ exposure to oxygen between uses, or cartridge life is significantly shortened. When not in use, ZOS Halo should always be stored in the Testing Holder to preserve the cartridge. With typical use, a cartridge should last between 5-15 bottles for about 2 months per bottle.
Q. How do I replace a cartridge?
A. Simply unscrew the old cartridge and replace it with a new one. When removing replacement cartridges from their container, but sure to limit exposure to oxygen. Immediately test the new cartridge and then either leave it in it’s protective holder until the next use (screw on cap), or immediately insert into an open bottle of wine. See Using Your ZOS Halo video for more information.
Q. How do I know when a cartridge needs to be replaced?
