OxySorb 300cc Oxygen Absorbers (100 Pack)
$9.99
The lowest-cost way to fill a lot of bags: a plain, food-grade 100-pack with no indicator or frills. Fine when you're sealing in one session and don't need to store leftovers.
Pros
- Lowest cost per absorber in the group
- Food grade, iron-based; a long-standing basic
- 300cc size covers most 1 to 2 gallon bags
Cons
- No oxygen indicator dot
- Basic packaging is not resealable, so open the pack only when ready to use
- Shorter track record than the category leaders
The exact product
These are OxySorb 300cc iron-based, food-grade oxygen absorbers, 100 to a plain sealed pack with no indicator and no resealable pouch. They are the lowest-cost way to fill a lot of bags, best when you are sealing everything in one session and do not need to store leftovers.
Best for
- One-session bulk projects where you use the whole pack at once
- The lowest possible cost per absorber
- Filling many bags at the same time
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
- Any use as a substitute for refrigeration or freezing
- Anyone who needs to store leftover packets, since the pack is not resealable
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 capacity, 100 count
- No indicator dot; standard non-resealable pack
- Iron-based and food grade
Independently verifiable
- 300cc suits roughly a 1 to 2 gallon container
- Once opened, the pack should be used promptly
Owners consistently report
- A long-standing basic with a shorter track record than the leaders
Our reading of the evidence
- Buy it only if you will use the whole pack in one go; otherwise a resealable or strip pack wastes fewer absorbers
What it costs to own
Cheapest per absorber, but the non-resealable pack is the catch: open it only when you are ready to seal everything, because exposed leftovers are spent within about half an hour.
How it fails, and what to watch
- Left exposed to air, an absorber is spent within roughly 15 to 30 minutes
- Used on moist food it fails the purpose and is a safety risk, not just a waste
- Too little capacity for the container leaves residual oxygen
Limits of this review
We do not lab-measure residual oxygen; sizing follows the community and manufacturer standard. What is safe to store long term is a food-safety question: follow USDA and the National Center for Home Food Preservation.
Common questions
How many do I need per gallon?
Roughly 300 to 500cc per gallon of dry food, so a 300cc packet suits a 1 to 2 gallon container.
Can I use them for sugar or salt?
No. Oxygen absorbers fuse sugar and salt into a solid brick. Store those dry 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.
Can I save leftovers?
Not easily; the pack does not reseal. Plan to use the whole pack in one session, or repackage leftovers into a vacuum-sealed bag immediately.

Alternatives
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.
The bucket-size absorber: one 2000cc packet is sized for a 5-gallon bag or pail, from the same trusted Wallaby line as our top pick. Individually sealed so the ones you don’t use stay fresh.
The value pick that still includes an oxygen indicator: a popular mid-count pack that seals well for oily foods like jerky and nuts without the premium price.
