O2frepak 300cc Oxygen Absorbers (50 Pack)
$13.99
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.
Pros
- Includes an oxygen indicator at a value price
- Food grade; owners rate it well for oily foods such as jerky and nuts
- Packed individually in a resealable vacuum bag so packets stay fresh
- 300cc size covers most 1 to 2 gallon bags
Cons
- 50-count pack means a higher per-run cost for big storage projects
- Indicator colour can be harder to read than the premium brands
The exact product
These are O2frepak 300cc iron-based, food-grade oxygen absorbers, 50 to a resealable vacuum bag, with an oxygen indicator. They are a popular value pick that owners rate well for oily foods such as jerky and nuts, without the premium price of the category leaders.
Best for
- Value-minded long-term storage of dry staples
- Oily dry foods such as jerky and nuts, where owners report good results
- People who want an indicator dot at a lower price
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
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 with an oxygen indicator
- Packed in a resealable vacuum bag
- Iron-based and food grade
Independently verifiable
- 50-count size suits smaller or occasional projects
- 300cc suits roughly a 1 to 2 gallon container
Owners consistently report
- Popular and well rated, especially for oily foods; a few find the indicator colour harder to read
Our reading of the evidence
- The best balance of price and features for a small to mid project, since it keeps the indicator the bare-bones packs drop
What it costs to own
The 50-count pack means a higher per-run cost than a 100-pack for big projects, but the resealable bag keeps leftovers fresh. Use about 300 to 500cc per gallon.
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.
Is 50 enough?
For a handful of 1 to 2 gallon bags, yes. For a large pantry build, a 100-count pack is more economical per absorber.
