Oxygen absorbers typically last for about 30 minutes once opened and exposed to air before they lose their effectiveness.
Oxygen absorbers typically last about 1-2 years before they need to be replaced.
Once opened, oxygen absorbers begin working immediately and have a very short active lifespan if left exposed to air. Typically: Within 10–15 minutes: They start absorbing oxygen quickly. Within 30–60 minutes: Most of their capacity is already used. Within 1–2 hours: They may become fully spent, depending on size and humidity. To extend their usability after opening: Reseal the remaining absorbers in an airtight jar, zip bag, or mylar pouch with as much air removed as possible. Ideally store with a small silica gel pack to control moisture. Properly resealed, unused absorbers can last up to a few days, but for best performance, try to use them within the same day.
