Why Choose Freshus Oxygen Absorbers?
There are many oxygen absorbers on the market, but independent testing proves our premium brands consistently outclass the competition (including Harvest Right, Packfresh, and Wallaby) by up to 35% to 45% in actual, real-world capacity.
-
More Time to Work: Lower-quality absorbers require you to rush and seal immediately. Our high-capacity absorbers give you up to 90 minutes to safely package and seal your food without a significant loss to their actual capacity.
-
Maximum Oxygen Depletion: Lowers oxygen levels inside your sealed Mylar bag to less than 0.1%. In comparison, standard vacuum sealing only reduces oxygen levels to about 2.0%.
-
Completely Safe & Non-Toxic: Made of a chemical compound where the active ingredient is powdered iron oxide. While they are not edible, they are entirely non-toxic, emit no harmful gases, and do not alter the fresh smell, taste, or nutritional value of your food.

There are numerous options available for purchasing mylar bags and oxygen absorbers. So, why do we say "just better bags?" What sets us apart? It's quite simple, really...our products stand out. And it isn't just a catchy slogan; our bags truly excel, as confirmed by testing. Among all of our retail competitors, we earned the highest rankings for both bags and oxygen absorbers. And it's not just a slight edge. Our OxyFree absorbers rated 35-45% better than Harvest Right, Packfresh and Top Mylar, and almost 400% their rated capacity (our 300cc absorbers rated a whopping 1106cc actual). Two brands tested (Wallaby & Amazon Full-Seal) didn't even meet their rating and one (Home Sense) had very little excess capacity (barely enough to allow time to open the bag and move the absorbers to mylar bags.)
The benefits of stronger absorbers are two-fold. First, it means your food will be oxygen free longer, giving you peace of mind. Second, it gives you more time to work. Using our competitors' oxygen absorbers, you’ll have to rush to package your food. With ours, you have up to 90 minutes to package your food, without significant loss to actual capacity. Dollar for dollar, based on their ACTUAL, independently tested capacity, our absorbers end up costing well less than our competitors' products.
