PackFreshUSA Oxygen Absorber

Vacuum sealers remove air, but they leave behind a small amount of residual oxygen that can still degrade food over time. Oxygen absorbers chemically remove nearly all oxygen from the container, which is significantly more effective for long-term storage and can extend shelf life up to 25 years.

Yes, these are food-grade and non-toxic. They are designed to be placed directly into your storage containers with your food items without posing any safety risks.

The 1000cc capacity is generally intended for larger storage containers, such as 1-gallon Mylar bags or larger buckets. If you are storing smaller quantities, you may need to use multiple smaller packets or ensure your container size matches the absorber's capacity to be effective.

Once the main package is opened, the absorbers begin working immediately. It is best to use them quickly or seal the remaining packets in a small, airtight jar or vacuum-sealed bag to prevent them from activating before you are ready to use them.

No, oxygen absorbers are single-use items. Once they have absorbed the oxygen in a container, they are spent and cannot be recharged or reused.
