Most wine stoppers just create a seal. The Pulltex AntiOx goes further, using a patented active carbon filter to interrupt oxidation the moment you close the bottle: it neutralises the volatile compounds that drive oxidation, so the oxygen left in the bottle can't react with the wine. The result is that an opened bottle stored upright stays close to its original character for over seven days, without the vinegary off-notes that develop when wine is simply recorked. "Recommended by the Spanish and Italian Sommelier Associations." How the Active Carbon Filter Works When you close the bottle, the filter inside the AntiOx absorbs the volatile compounds responsible for accelerating oxidation. Oxygen is still present in the bottle, but without those compounds it can no longer react with the wine or produce acetic acid. The stopper doesn't need charging, replacing, or pumping. You just close the bottle. Patented active carbon filter technology Neutralises oxidation-driving volatile compounds No pumping or vacuum mechanism required Keep the bottle upright for best results Lifespan and Durability The filter is rated for 1,000 uses or five years of operation, whichever comes first. For most home wine drinkers that covers years of regular use. The filter is not replaceable, but the stopper itself is designed to last rather than be a consumable. 1,000 uses or 5 years rated lifespan Active carbon filter built in, not replaceable Fits standard wine bottle necks Wine Preservation in Practice The AntiOx keeps wine fresh for over a week when the bottle is stored upright. That covers the typical gap between opening a bottle mid-week and finishing it at the weekend, without any noticeable deterioration in flavour or aroma. Preserves wine for 7 days or more Prevents acetic acid production (vinegar taste and smell) Store bottle in vertical position for optimal performance Why Choose the Pulltex AntiOx Vacuum pump systems remove some oxygen but leave the rest to work on the wine. The AntiOx doesn't remove oxygen; it prevents it from reacting with the wine at all, which is a more complete approach to preservation.
