1-Gallon Mylar Bag 1 x 300cc (or 1 x 500cc for extra protection)

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.

Key Benefits

  • Preserves Quality: Keeps the original freshness, taste, aroma, and vibrant color of your stored food items.

  • Prevents Spoilage: Stops food from becoming stale, rancid, or moldy. Eliminates the growth of aerobic pathogens, spoilage organisms, mildew, and anaerobic microorganisms.

  • Eliminates Preservatives: Removes the need for unhealthy chemical preservatives like sorbates, benzoates, BHA, BHT, PFAS, and sulfur dioxides.

  • Protects Nutrients: Prevents the oxidation of valuable vitamins (especially A, C, and E) and polyunsaturated oils/fats.

  • Versatile Storage Applications: Perfect for grains, rice, beans, flour, sugar, salt, spices, oats, pasta, powdered milk, freeze-dried foods, dehydrated meats/jerky, pet foods, and even non-food items like tools, collectibles, and artwork.

 

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-Sealdidn'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.

    I love that the oxygen indicator in these is so clear! Some you have to squint for, but this one is bright and large.

    I know that oxygen absorbers do not necessarily create a vacuum in the bag but these always do, it reassures me that they are working like they're supposed to! I love these!

    They work great. I especially like them for small bags because they easily fit in. They also work well for all the different sizes I used

    Oxygen Absorber

    Posted by Jeremy Penney on 30th May 2024

    I order 20 packs of 10 500CC oxygen absorbers and only received 19 of them. Luckily I caught the mistake before I had filled the bags with food.
