Oxygen absorbers are small packets that remove most of the oxygen from a sealed container, which helps slow spoilage in dry foods such as rice, beans and flour. They are usually paired with Mylar bags or glass jars with tight lids.
The six products below are packs sold for home food storage. We have not used these products ourselves, so confirm the packet size, count and the intended use on the current listing before buying. Absorbers are not right for every food, so read the maker’s guidance carefully. Plan the whole job before you open a pack, because absorbers start working as soon as they meet air.

Oxygen Absorber FAQ
How many absorbers do I need per container?

Are oxygen absorbers safe to handle?
They are sealed for storage use and are not meant to be eaten, so keep them away from children and pets.
Do they work in any container?
They need a truly airtight seal, so Mylar bags and good jars work best.
