The exact product
These are PackFreshUSA 300cc iron-based, food-grade oxygen absorbers, 100 to a pack, from a long-standing US supplier. They carry an oxygen indicator to confirm the packets are active and ship with a printed storage guide, aimed at buyers who want a trusted source over the lowest unit price.
Best for
- Long-term storage of dry staples in 1 to 2 gallon mylar bags and jars
- Buyers who want a made-in-USA supplier and an indicator dot
- Anyone new to long-term storage who wants the included guidance
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
- Made in the USA with a storage guide in the box
- Individually sealed so packets arrive fresh, not pre-activated
Independently verifiable
- Iron-based absorbers protect only genuinely dry foods
- 300cc suits roughly a 1 to 2 gallon container
Owners consistently report
- Well rated, with a smaller review history than the category leaders
Our reading of the evidence
- You pay a little more for a trusted US source and the indicator; reasonable if provenance matters to you
What it costs to own
Cost per absorber is above the value multipacks, but you are paying for a known supplier and the indicator. Use about 300 to 500cc per gallon, so one 100-pack covers a large pantry project.
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 the indicator reliable?
The indicator dot changes colour once a packet is spent, which is a useful at-a-glance check, but treat it as a guide and reseal unused packets promptly.

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.
