Review on 500Cc Oxygen Absorber Packs - 50 Pack (5 X 10) By PackFreshUSA: Non-Toxic Food Grade For Long-Term Food Storage & Preservation With Guide Included by Josh Hamler

Revainrating 5 out of 5

These work great for my opinion

I have used several different kinds of oxygen absorbers. Most of them have fallen short and after a few months air is allowed back in the mylar bag. I have purchased several of these for my freezedryed food. I have not had a single bag let air in with these. They work really well. I'm so glad I found them.

Pros
  • Work exactly as expected. Small quantity per pack is perfect for routine use.
Cons
  • May not be effective for preserving foods with high sugar content
