• 300cc OxyFree Absorbers – The go-to standard for 1-Quart, 2-Quart, and 1-Gallon Mylar bags.

• 2000cc OxyFree Absorbers – Heavy-duty protection specifically sized for 5-Gallon Mylar bags and 5-Gallon food storage buckets.

Why Choose OxyFree?

OxyFree absorbers are independently proven to outperform competitor brands (including Harvest Right, Packfresh, and Wallaby) by 35% to 45% in actual real-world capacity.

• High capacity gives you more time to prep: Because Oxyfree absorbers are overweighted, you have up to 90 minutes to prep your food.  Some oxygen absorbers that aren't so heavily weighted fall below their rated capacity after 15 minutes.

• Built-in Oxygen Indicator: Every sealed pack includes an OxyEye indicator so you can instantly confirm freshness before opening.

• Non-Toxic & Food-Safe: FDA-approved for direct contact with food. They emit no harmful gases, create no toxic residue, and leave smell and taste unaffected.

Sizing & Usage Recommendations

Pro Tip: Keep the acronym MOLT in mind for long-term food storage! Your main targets to control are Moisture, Oxygen, Light, and Temperature. Combining OxyFree absorbers with high-barrier Mylar bags provides maximum protection.
