FreshUS 300cc Oxygen Absorbers (100 Pack)
$11.99
A high-volume, cheap-per-unit absorber that ships in ten sealed strips of ten, so you open only what a session needs. No indicator dot, but a huge, consistent owner base.
Pros
- Very low cost per absorber for large storage projects
- Individually packed in 10 sealed strips of 10 so unopened strips stay fresh
- Food grade with a large, consistent owner base
- 300cc suits the common 1 to 2 gallon mylar bags
Cons
- No oxygen indicator dot, so you can't confirm activity at a glance
- Once a strip is opened the remaining packets must be used quickly
The exact product
These are FreshUS 300cc iron-based, food-grade oxygen absorbers, 100 to a pack in ten sealed strips of ten, so you open only what a session needs. There is no indicator dot, but the owner base is large and consistent, and the cost per absorber is among the lowest here.
Best for
- Large storage projects where cost per absorber matters
- People who seal in planned sessions and open one strip at a time
- Buyers who do not need an indicator dot
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, 100 count in 10 sealed strips of 10
- No oxygen indicator dot
- Iron-based and food grade
Independently verifiable
- The strip packaging keeps unopened strips fresh
- 300cc suits roughly a 1 to 2 gallon container
Owners consistently report
- A large, consistent owner base; the lack of an indicator is the main trade-off noted
Our reading of the evidence
- The strip format is the smart part: it limits how many absorbers you expose at once, which is the usual way people waste them
What it costs to own
Among the cheapest per absorber for bulk projects. Because there is no indicator, plan your sealing so you use a whole strip at once and reseal or discard any leftovers from an opened strip quickly.
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.
No indicator dot: is that a problem?
It just means you cannot confirm a packet is active at a glance. Work from freshly opened strips and it is a non-issue; the trade-off buys a lower price.

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.
