Once you open a bottle, the wine is exposed to oxygen. Over time, the oxygen will damage the wine’s flavor. Only ZOS Halo removes all of the oxygen. Other systems remove some, but even a little oxygen will damage your wine.
The ZOS Halo is made of an oxygen barrier stopper attached to a replace-able cartridge. You simply insert the ZOS Halo Stopper into an open bottle of wine and within minutes, our patented, non-toxic cartridge absorbs all of the oxygen in the bottle. Each cartridge lasts 5-15 bottles and is easily replace. The system comes with a tester to know when you need to replace your cartridge.
Included with each ZOS Halo is a testing holder. This holder performs two functions. First, by inserting the ZOS Halo Stopper into the tester, it will perform a test to tell you if the cartridge is still good, or if it needs to be replaced by displaying a green (good) or red (change) light. The holder is also a sealed container that will preserve the life of the cartridge between uses.
Because the cartridge is such a powerful oxygen absorber, exposure to oxygen will significantly reduce cartridge life. When not in use, the ZOS Halo should always be store in this protective holder.
