Wallaby 300cc Oxygen Absorbers (100 Count)
$27.99
The consensus pick for long-term dry storage: a reliable iron-based absorber with an oxygen indicator dot and resealable bulk packaging, so the packets you don't use don't spoil in the drawer.
Pros
- Oxygen indicator dot shows at a glance whether a packet is still good
- Ships in a resealable, individually vacuum sealed pouch so unused packets stay fresh
- Food grade, iron-based; big following in the freeze-dry and mylar community
- 300cc suits the most common 1 to 2 gallon mylar bags
Cons
- Costs more per absorber than the bare-bones value multipacks
- A few owners report a faint chemical smell on some runs
The exact product
These are Wallaby 300cc iron-based, food-grade oxygen absorbers, sold 100 to a pouch with a colour-change oxygen indicator dot. They ship in a resealable, vacuum-sealed pouch so the packets you do not use in one session do not spoil. At 300cc each they suit the most common 1 to 2 gallon mylar bags.
Best for
- Long-term storage of genuinely dry, shelf-stable staples: rice, beans, oats, flour, pasta, powdered milk
- 1 to 2 gallon mylar bags, jars and sealed containers of dry goods
- People who open a pouch across several projects, since it reseals to keep unused packets fresh
Not for
- Moist, oily or high-moisture foods, where low oxygen can favour botulism and the absorber does not make the food safe
- Sugar or salt, which oxygen absorbers fuse into a solid brick
- Use as a substitute for refrigeration or freezing of perishable food
What we can and can't verify
We separate what the maker claims from what independent sources confirm, what owners report, and where we are drawing an inference. We do not bench-test products.
The manufacturer states
- 300cc absorbing capacity per packet
- Colour-change oxygen indicator dot
- Resealable, individually vacuum-sealed pouch
- Iron-based and food grade
Independently verifiable
- Iron-based absorbers protect only genuinely dry, shelf-stable foods
- 300cc is sized for roughly a 1 to 2 gallon container
- The indicator dot changes colour once a packet is spent
Owners consistently report
- A large following in the mylar and freeze-dry community praises reliability
- A few owners report a faint chemical smell on some runs
Our reading of the evidence
- The indicator dot and resealable pouch justify the small premium over bare multipacks, because a spoiled bag of loose, exhausted absorbers is the common failure
What it costs to own
Cost per absorber is a little above bulk multipacks, but you waste fewer because the pouch reseals. As a rule use about 300 to 500cc per gallon of dry food, so a single 300cc packet suits a 1 to 2 gallon bag and one 100-count pouch covers a large pantry project. There is no ongoing cost beyond the absorbers themselves.
How it fails, and what to watch
- Absorbers left exposed to air (an open or torn pouch) are exhausted within roughly 15 to 30 minutes and become useless
- Using them on moist food fails the purpose and is a safety risk, not just a waste
- Using them with sugar or salt cements the contents into a brick
- Too little capacity for the container leaves residual oxygen and shortens storage life
Limits of this review
We do not lab-measure residual oxygen. Sizing guidance is the community and manufacturer standard, not a bench result. What is safe to store long term is a food-safety question: follow USDA and the National Center for Home Food Preservation, not a packet count.
Common questions
How many do I need per gallon?
Roughly 300 to 500cc per gallon of dry food. A single 300cc packet suits a 1 to 2 gallon mylar bag; step up the count or capacity for larger buckets.
Can I use them for sugar or salt?
No. Oxygen absorbers fuse sugar and salt into a solid brick. Store those dry, in an airtight container, with no absorber.
Do they work for moist foods?
No. They protect only dry, shelf-stable foods, and low oxygen around moist food can favour botulism. Route perishables to refrigeration or freezing and follow USDA and NCHFP guidance.
How do I keep the unused ones fresh?
Press the air out and reseal the pouch immediately, or clip and vacuum it. Once exposed to air, loose absorbers are spent within about half an hour.
