Product review

Each purchase ships as multiple sealed ten-packs of oxygen absorber sachets. Every group is heat-sealed immediately after production and kept closed to limit exposure to air; packets are not repackaged once opened, which helps preserve their shelf life and activity prior to use.

Each packet is rated at 400cc capacity. That volume is intended to be used with one-gallon Mylar bags and other airtight containers to prolong the shelf life of non-perishable dry goods — examples include flours and baking mixes, spices, grains, beans, pasta, cereal, dehydrated produce, and commercially freeze-dried meals.

The packet envelope is made from food-grade materials and the product is manufactured to meet common safety standards for food storage. The absorber contents are meant for both short- and long-term storage of edible items when used according to instructions; batches are tested to ensure consistent material quality.

Outer packaging includes a reusable zipper-seal pouch so unopened ten-packs can be kept together and retrieved as needed. Keep in mind these packets remove oxygen (roughly 21% of air) rather than the total air volume, so bags will not always look like vacuum-shrink bags — about four-fifths of the original air volume remains even after oxygen removal. For best results follow recommended packet counts for your container size.

Pros

Sold in sealed ten-packs to preserve potency
High 400cc capacity suited for 1-gallon Mylar bags
Food-grade materials and quality testing

Cons

No visual freshness indicator on some packs
Not every user reports consistent performance
Removes oxygen only; bags may not appear vacuumed

VerdictThese 400cc absorber packets are a practical, affordably sized option for preserving dry goods in 1-gallon Mylar bags and similar containers. Packaging is sealed at production to protect effectiveness, and the zipper pouch helps keep unused packs organized. Performance is generally strong at removing oxygen, though some buyers report occasional inconsistent results and the units won’t remove the n

Manufactured overseas

Since these are made overseas I won’t use them inside food I prepare, but they seem well made and will be used for other storage tasks.
Jeanine cerello 5/5

Removes oxygen reliably

I use these in cans and Mylar. They consistently remove oxygen and I include them as a backup in case seals fail. Would recommend.
Macandme 5/5

Good value and packaging

Kept our dry goods fresh; the 10-pack grouping is handy so you don’t have to open a large bulk of packets at once.
Gem Gem 5/5

Convenient small packs

They work well. Ten-packs are ideal for smaller jobs and avoid wasting unused packets. I doubled them in some freeze-dried bags for extra assurance.
Viva Cristo Rey 1/5

Didn’t work for my bags

I used the recommended count for my bags and none of them sealed — I had no success with those batches.
B Anderson 5/5

Sealed jars on their own

I placed packets in mason jars and several sealed themselves within hours. They pulled a tight seal where none existed before. I’ll buy more.
T. Hayes 5/5

Exceeded my previous packs

I hesitated at first because there was no pink freshness dot, but after testing them they tightened bags far better than the other brand I used. Very effective; I’ll reorder.
