Hey there! As a supplier of oxygen absorbers, I've seen firsthand the importance of these little heroes in keeping all sorts of products fresh. Oxygen absorbers are used in a wide range of industries, from food to electronics, to prevent oxidation and extend the shelf life of products. But not all oxygen absorbers are created equal. In this blog, I'll break down the differences between different types of oxygen absorbers and how to choose the right one for your needs.
Types of Oxygen Absorbers
Iron-based Oxygen Absorbers
Iron-based oxygen absorbers are the most common type on the market. They work by oxidizing iron powder inside the packet. When the iron reacts with oxygen, it forms iron oxide, effectively removing oxygen from the surrounding environment. These absorbers are great for a variety of applications, especially in the food industry.
One of the big advantages of iron-based oxygen absorbers is their high oxygen absorption capacity. They can absorb a large amount of oxygen relative to their size, which makes them ideal for large packages or products that require a low-oxygen environment. They're also relatively inexpensive, which is a plus for businesses looking to keep costs down.
However, iron-based oxygen absorbers do have some limitations. They require a certain level of humidity to work effectively. If the environment is too dry, the oxidation process slows down, and the absorber may not work as well. Also, once they've absorbed oxygen, they can't be reused.

Activated Carbon Oxygen Absorbers
Activated carbon oxygen absorbers work a bit differently. Instead of relying on oxidation, they use the porous structure of activated carbon to adsorb oxygen molecules. Activated carbon has a large surface area, which allows it to trap oxygen and other gases.
These absorbers are often used in applications where odor control is important. They can not only absorb oxygen but also other volatile organic compounds (VOCs) and unpleasant odors. This makes them a popular choice for products like electronics, where preventing oxidation and keeping the product free of odors is crucial.
One of the benefits of activated carbon oxygen absorbers is that they can work in a wide range of humidity levels. They're not as dependent on moisture as iron-based absorbers. They're also more environmentally friendly because they can be regenerated and reused.
On the downside, activated carbon oxygen absorbers generally have a lower oxygen absorption capacity compared to iron-based ones. They may not be the best choice for products that require a very low-oxygen environment.
Double Absorption Type Oxygen Absorbers
The Yome-B Double Absorption Type is a unique type of oxygen absorber that combines the benefits of both iron-based and activated carbon absorbers. It has a dual-action mechanism that allows it to absorb oxygen through oxidation and adsorption simultaneously.
This type of absorber offers a high oxygen absorption capacity, similar to iron-based absorbers, while also providing odor control like activated carbon absorbers. It's a great all-around solution for products that need both oxygen removal and odor prevention.
The double absorption type is also more versatile in terms of humidity. It can work effectively in a wider range of moisture levels compared to traditional iron-based absorbers.
Choosing the Right Oxygen Absorber
When it comes to choosing the right oxygen absorber for your product, there are a few key factors to consider.
Product Type
The type of product you're packaging is one of the most important considerations. For food products like nuts, rice, and coffee beans, iron-based oxygen absorbers are often a good choice because they can effectively remove oxygen and prevent spoilage.

For electronics or products that are sensitive to odors, activated carbon or double absorption type oxygen absorbers may be more suitable. They can not only protect the product from oxidation but also keep it free of unpleasant smells.
Packaging Size
The size of your package also matters. If you have a large package, you'll need an oxygen absorber with a high absorption capacity. Iron-based absorbers are usually a good option in this case because they can absorb a large amount of oxygen. For smaller packages, you may be able to get away with a smaller, less powerful absorber.
Humidity Level
As mentioned earlier, different oxygen absorbers have different requirements when it comes to humidity. If your product will be stored in a dry environment, an activated carbon or double absorption type absorber may be a better choice because they're less dependent on moisture. If the environment is humid, iron-based absorbers can work well.
Conclusion
In conclusion, there are several types of oxygen absorbers available, each with its own unique advantages and limitations. Iron-based absorbers are great for high-capacity oxygen removal, especially in the food industry. Activated carbon absorbers are ideal for odor control and work well in a wide range of humidity levels. Double absorption type absorbers offer the best of both worlds, combining high absorption capacity with odor control.
If you're in the market for oxygen absorbers and need help choosing the right one for your product, don't hesitate to reach out. We're here to assist you in finding the perfect solution for your business. Whether you're looking to keep your nuts and rice fresh, your coffee beans flavorful, or your electronics free of oxidation and odors, we've got you covered.
