Modern refrigerators are no longer simple cooling boxes products, turning into complex climate systems that preserve the freshness and taste of food. One of the key elements of this technological upgrade was the AirFreshFiltersystem, which can be found in many models in the mid-range and premium segment. Many owners of new equipment often wonder: what kind of device is this, is it really necessary, or is it just a marketing ploy designed to justify the high price of the gadget?
In fact, AirFreshFilter it is not just a plastic box with coal chips, but an important air circulation unit inside the chamber. It is responsible for neutralizing unpleasant odors that occur when storing foods with strong aroma, such as fish, spices or overripe fruits. Moreover, high-quality filtration helps reduce the concentration of ethylene, a gas that speeds up the ripening and spoilage of vegetables. If you notice that a strange smell has appeared in your refrigerator that does not disappear after washing, most likely the problem lies precisely in the condition of this filter or the need to replace it.
In this article we will analyze in detail the structure of the system, the principles of its operation and give practical advice on maintenance. Understanding how it works will allow you to extend the life of your equipment and keep your food fresh much longer. Ignoring the condition of the filter element can lead to bacteria beginning to actively multiply on the walls of the evaporator, which will require more serious intervention.

Ignoring the condition of the filter element can lead to bacteria starting to actively multiply on the walls of the evaporator, which will require more serious intervention.
The principle of operation of the air purification system
The basis of the work AirFreshFilter is the forced or natural circulation of air masses through a special filter material. Most modern models, such as Samsung or LG, use carbon filler, which has a high adsorbing capacity. Air from the main chamber of the refrigerator is sucked in by a fan or passes by gravity through the filter cells, where odor molecules get stuck in the pores of activated carbon.
The cleaning process occurs continuously while the refrigerator is plugged in. Activated carbon has a porous structure, the surface area of which can reach several hundred square meters per gram of substance. It is this feature that allows for effective capture of volatile organic compounds. However, it is worth understanding that the filter resource is not infinite: over time, the pores become clogged and the cleaning efficiency decreases.
⚠️ Attention: Some filter models require periodic “regeneration” in sunlight, while others are disposable. Always check the technical documentation for your specific refrigerator model so as not to damage consumables through improper maintenance.
It is important to note that the system AirFreshFilter often works in conjunction with the function No Frost. In such refrigerators, air circulates especially intensively, distributed over all shelves. If the filter is dirty or missing, the smell from one product will instantly spread throughout the entire volume of the chamber, permeating even hermetically sealed goods. Therefore, the integrity and cleanliness of the filter element are critical for hygienic storage.
There are also more advanced systems where, in addition to carbon, silver ions or special antibacterial coatings are used. They not only remove odors, but also destroy up to 99% of bacteria entering the air stream. This is especially true for families with small children, where the issue of sterility of products is especially acute.
Types of filters and their differences
There are several types of cleaning systems on the household appliances market, and it is important not to confuse them with each other. Carbon filters are the most common type. They are a cartridge filled with activated carbon granules. Their main task is the adsorption of odors. The service life of such elements is usually from 6 to 12 months, after which they must be replaced.
The second type is deodorizing filters based on mineral components or zeolite. They are often found in brand models Electrolux and Beko. Such elements can last longer, sometimes up to two years, and can often be restored by washing or drying. However, their effectiveness against strong odors may be lower than that of high-quality coal.
The third type is systems with ionization or using ultraviolet light. Here AirFreshFilter may not have a replaceable cartridge in the usual sense, but be an emitter or a plate that generates ions. Such systems require minimal maintenance; usually just wiping them from dust is enough. But refrigerators with such equipment are much more expensive.
Below is a table that helps compare the main characteristics of different types of filters:
| Filter type | Service life | Recovery | Efficiency |
|---|---|---|---|
| Coal (Carbon) | 6-12 months | Not subject to | High |
| Zeolite | 12-24 months | Washing/Drying | Medium |
| Silver thread (Silver Plus) | Up to 5 years | Not required | High (antibacterial) |
| Mineral (Deo Fresh) | 2-3 years | Sunlight | Medium/High |
The choice of the correct type of consumables depends on the intensity of use of the refrigerator. If you store a lot of products with a strong odor, it is better to focus on models with powerful carbon or combined systems. For standard use, the basic mineral filters that come with the kit are sufficient.
How to understand that a filter requires replacement
You can determine resource depletion AirFreshFilter by several indirect and direct signs. The most obvious of them is the appearance of a persistent unpleasant odor inside the chamber, which does not disappear after general cleaning and removal of spoiled products. If, after washing the refrigerator with soda, the smell returns after a couple of days, it means that the filter has stopped coping with its task.
The second sign is a change in the appearance of the filter element. If the design provides a transparent lid or the possibility of removal, inspect the filler. Darkening of granules, the appearance of mold or sticking of the material indicates that the pores are completely clogged. In some premium models, a special indicator lights up on the control panel, signaling the need for replacement.
It is also worth paying attention to the condition of the products. If vegetables and herbs begin to deteriorate faster than usual, and the milk acquires a strange taste, there may be an increased concentration of bacteria or ethylene in the air due to the ineffective operation of the cleaning system. AirFreshFilter in this case, an immediate inspection is required.
Ignoring these signals can lead to the smell becoming ingrained in the plastic parts of the interior of the refrigerator, and it will be extremely difficult to remove it. In advanced cases, even replacing the filter will not help immediately; long-term ventilation and treatment with special means will be required.
Instructions for cleaning and maintenance
Maintenance of the air purification system depends on its type, but there are general rules that apply to most models. Before starting any work, it is necessary unplug the refrigerator from the power supply. This is a safety requirement that cannot be ignored, since you will be working near electrical components and moisture.
First, find the location of the filter. In most cases, it is located on the back wall of the refrigerator compartment, sometimes hidden by a decorative panel or located in a niche next to the lampshade. Carefully remove the cartridge following the instructions for your model Samsung, LG or other manufacturer.
- 🧼 Wash the filter housing with warm water and mild detergent if the instructions allow washing.
- ☀️ If you have a mineral or zeolite filter, remove granules and dry them in direct sunlight for 3-4 hours.
- 🚫 Never wash disposable carbon filters with water - this will lead to their damage and loss of absorbent properties.
- 🔍 Inspect the seat in the refrigerator for dust and dirt, wipe it with a dry soft cloth.
After cleaning or replacing, you must install the element back until it clicks. Make sure it fits tightly and does not wobble. Only after this can you turn on the refrigerator. Full activation of the filter may take from several hours to a day, during which the cleaning efficiency will gradually increase.
☑️ AirFreshFilter maintenance checklist
Replacing the filter: step-by-step algorithm
When the resource of the filter element is exhausted, it must be replaced. There is no point in using an old, used filter, as it becomes a source of bacteria. You can buy the original AirFreshFilter in service centers or specialized stores of spare parts for household appliances.
The replacement process is quite simple, but requires care. First, remove the old cartridge. If it becomes dry or stuck, do not use excessive force to avoid breaking the plastic clips. It's better to gently rock it from side to side. Dispose of the old filter according to the regulations in your region, as it contains chemical sorbents.
The new filter usually comes in a sealed package. Remove the protective film immediately before installationotherwise the filter will not work as air will not be able to pass through the packaging material. This is a common mistake of users who forget to remove the factory protection.
⚠️ Attention: Do not use filters from other models or universal analogues of dubious quality. Incorrect dimensions or resistance to air flow can disrupt the operation of the system No Frost and lead to fan failure or compressor overheating.
Insert the new cartridge into the slots, observing the orientation (usually the arrow on the case indicates the direction of air flow or the installation side). After installation, check the tightness. If the model has a function for resetting the replacement indicator, perform this procedure through the settings menu so that the system keeps the correct time count.
What will happen if you do not change the filter?
If you do not change the filter for a long time, it becomes a breeding ground for mold and bacteria. The air passing through such a filter is not cleaned, but, on the contrary, becomes contaminated with fungal spores that settle on the products. This can cause food poisoning and allergic reactions. In addition, a clogged filter creates additional resistance for the fan, which increases the load on the motor and energy consumption.
Common operating errors
Users often make mistakes that negate the efficiency of operation AirFreshFilter. One of the most common is trying to wash a disposable carbon filter with water. Water washes away the active substances and destroys the structure of the granules, making the filter useless. Always check the instructions to see if your specific type can be washed.
Another mistake is installing the filter upside down or the wrong way around. The housing often has markings UP or arrows indicating the correct position. If you mix up the sides, the air will pass past the filter layer and cleaning will not occur. Carefully study the diagram on the case before installation.
Also, do not wait until the filter completely stops working. Preventative replacement or cleaning must be carried out strictly according to regulations, even if there are no visual odors. Accumulated harmful substances can begin to be released back into the chamber when temperature or humidity changes.
Some users try to “reanimate” carbon filters by calcining them in the oven. Doing this is strictly prohibited! Coal can ignite or release toxic substances when heated. Follow only the official recommendations of the manufacturer of your equipment.
Frequently asked questions (FAQ)
Is it possible to use a refrigerator without AirFreshFilter installed?
Technically, the refrigerator will work and cool products without filter. However, in chambers with a system No Frost the absence of a filter can lead to faster spread of odors and poorer air circulation if the design provides for a mandatory passage through the filter. It is recommended not to operate equipment without it for a long time.
How often should you change the filter in the refrigerator?
The average service life of carbon filters is 6 months. Mineral and deodorizing elements can last up to 2 years. The exact period depends on the intensity of use of the refrigerator and the amount of food with strong odors. Monitor the indicators on the control panel, if any.
Where can I buy an original filter for my model?
Original consumables are best purchased from the manufacturer’s authorized service centers or from official partners. The packaging must indicate the compatibility code for your refrigerator model. The use of cheap analogues can reduce the cleaning efficiency.
Why did the smell not disappear immediately after replacing the filter?
The new filter takes time to activate. The coal must pick up moisture from the air and begin to work fully. This process may take 12 to 24 hours. If the smell persists for longer than a day, check the correct installation and tightness of the packaging removed from the new element.
