Many owners of modern household appliances do not even suspect that an important cleaning element is hidden inside their unit, which requires regular attention. The question of where the filter is located in the refrigerator becomes relevant when an unpleasant odor appears or the system ceases to effectively fight bacteria. Unlike washing machines, where filters are often located at the front, in refrigerators their location depends on the specific model and cooling system.
Most often, such elements are installed in models with a system No Frost, where air circulation plays a key role. The presence of a charcoal or antibacterial module helps keep food fresh longer, but over time its resource is exhausted. Understanding the design of your device is the first step to proper care and extending the service life of your equipment.
In this article we will look at the main locations of filter elements, methods for replacing them, and the nuances of servicing different brands. You will learn how to distinguish a replaceable cartridge from a simple deodorizer and why ignoring its condition can lead to damage to the evaporator.
Main types of filter systems in refrigerators
Before looking for a specific installation location, you need to figure out which filters can be used by the manufacturer in your model. The most common ones are carbon filtersthat adsorb odors, and antibacterial modulescontaining silver ions or other active substances. Some premium models are equipped with complex systems with UV radiation, which also require periodic replacement of components.
The location of the element directly depends on its functional purpose. If it is an air filter, it will be located in an area of active flow circulation. If we are talking about a water filter (in models with a dispenser), then you need to look for it in the lower part of the case or in the niche for vegetables. It is important not to confuse the removable cartridge with a non-removable mesh at the refrigerant inlet, which is serviced only by a technician.
- 🔹 Carbon cartridges - absorb ethylene and odors, extending the shelf life of vegetables.
- 🔹 Air ionizers - disinfect the flow passing through evaporator.
- 🔹 Water filters - purify water for the ice maker and drinking tap.
It is worth noting that in budget models the role of a filter can be performed by a simple sponge with activated carbon, attached to Velcro. In more expensive series, such as Samsung or LG, cassettes with a resource indicator are used, which are changed by turning or pressing a button. Understanding the type of your device will help you quickly navigate the space of the refrigeration chamber.
Where to look for a filter in the refrigerator compartment
If your refrigerator is equipped with an air purification system, the most likely place for its location is the inner wall of the refrigerator compartment. Manufacturers try to place the element so that it does not interfere with the installation of shelves, but is located in the active air exchange zone. Most often, the container or grille is located on the back wall, closer to the top, or on the side, in the area where the shelves are attached.
In models with the system Multi Air Flow the filter is often integrated into the air supply panel itself. This can be a horizontal slot or a vertical groove covered with a plastic cover. To gain access to the contents, sometimes it is enough to simply pull the cover towards you, in other cases you will need to unscrew one or two screws hidden under decorative plugs. Be careful when opening the plastic latches as the plastic becomes brittle in the cold.
⚠️ Attention: Before removing any panel inside the refrigerator compartment, be sure to unplug the unit from the electrical outlet. This will eliminate the risk of short circuits and protect electronic sensors from power surges.
Another common place is the ceiling of the chamber or the area above the upper shelves. Compact cassettes are often hidden here and can be easily removed by hand. If you see the "Air Filter" marking or a picture of drops/leaves on the plastic element, then this is exactly what you are looking for. In some cases, the filter may be located directly above the vegetable drawer to purify the air circulating in the lower, most humid zone.
Filter locations in the freezer and No Frost zone
B In the freezer, filters are less common, since low temperatures themselves preserve odors. However, in systems Total No Frost air flows from the freezer and refrigerator compartment are often mixed. In such cases, the filter may be located behind the back panel of the freezer, where the ventilation duct leads. It can be difficult to get to it without defrosting and removing the casing, so manufacturers often display a replacement indication on the display.
If we are talking about a water filter for an ice maker, then only the supply tube is located in the freezer, and the cartridge itself is usually hidden in the base of the refrigerator (bottom, behind the grille) or in the door. The plinth filter is accessible through a removable panel at the bottom of the housing. This is done for convenience: you do not need to climb inside the freezer to replace the cartridge.
When searching for an element in the freezer compartment, pay attention to the following areas:
- ❄️ The back wall behind the plastic evaporator box (requires removing the panel).
- ❄️ Ceiling freezer compartment (rarely, in premium models).
- ❄️ Door (only for water ice-making systems).
It is important to understand that if the filter is located deep inside the No Frost system (behind the evaporator), replacing it may require defrosting skills and working with fasteners. The instructions for such models often indicate that replacement must be carried out by an authorized service center so as not to disrupt the tightness of the circuit.
What will happen if you do not change the filter in the No Frost system?
If the filter becomes clogged with dust and ice chips, air circulation will be disrupted. This will lead to the formation of a “snow coat” on the evaporator, increased energy consumption and eventual breakdown of the fan.
Instructions for replacing and maintaining filters
The replacement process depends on the type of mount, but the general algorithm of actions is similar for most models. First, you need to find the label or instructions to determine the compatible part number of the consumable. Using non-original or unsuitable cartridges may result in a loose fit and leakage of untreated air past the filter.
For air filters that are simply inserted into the slots, the procedure takes a couple of minutes. The old element is removed and the new one is installed in the same position. If the filter is washable (for example, mesh with carbon coating), it can be washed with warm water and dried thoroughly at room temperature for 24 hours. Never do not put a wet filter back into a working refrigerator - this will lead to freezing of the channel.
☑️ Replacement algorithm filter
Water filters require more careful preparation. After installing a new cartridge, you must drain the first 2-3 liters of water to remove carbon dust from the system. It is also important to reset the resource counter on the control panel, if such a function is provided. Usually, to do this, you need to hold down the "Filter" button or key combination for 3-5 seconds until a beep sounds.
| Filter type | Service life | Signs of replacement | Can it be washed |
|---|---|---|---|
| Coal (air) | 6-12 months | Odd odors | No (drying only) |
| Antibacterial | 1-2 year | Mold appearance | No |
| Water (cartridge) | 6 months | Slow water flow | No |
| Mesh (rough) | Indefinite | Visible contamination | Yes |
Brand specifics: Samsung, LG, Bosch, Indesit
Different manufacturers use unique design solutions. For example, in refrigerators Samsung with technology Twin Cooling System two independent circuits are often used, and there can be one filter for each compartment or one common large volume. In models of this brand, the filter is often located on the right side wall of the refrigerator compartment and is closed with a rotating lid.
In technology LG a system is popular Hygiene Fresh+, where the filter is a multilayer structure located in the upper part of the rear wall. It is easily removable, but requires the purchase of original replacement units. In refrigerators Bosch and Siemens there is often a system AirFreshwhere the carbon module is built into a plastic case that can be changed entirely.
Budget models such as Indesit or Atlantmay not have factory filters included, but have seats for universal models. Owners of such devices are recommended to purchase universal carbon filter plates and place them in the air intake area, securing them with standard fasteners or Velcro.
⚠️ Attention: Technical characteristics and location of components may vary depending on the year of manufacture and the specific modification of the model. Always check the technical documentation (data sheet) of your device before starting work.
Common mistakes when searching and operating
One of the most common mistakes is trying to find a filter where it is not. In simple drip systems (“crying backdrop”), air filters are extremely rare. Owners of such models often disassemble the back wall in search of a non-existent element, risking damage to the freon tubes. If the instructions do not indicate the presence of a cleaning system, most likely it is not there.
Another mistake is ignoring replacement dates. Even if the filter looks clean, its adsorption capacity decreases over time. Coal saturated with odors may begin to release them back into the chamber when the temperature or humidity changes. Regular replacement is not marketing, but a necessity to maintain hygiene.
Also, users often forget to reset the indicator after replacement. The refrigerator electronics continue to “think” that there is an old filter and may not work correctly in energy saving or intensive cooling modes. Always check the status of the indicator on the display after servicing.
Is it possible to use a refrigerator without a filter?
In the short term - yes, the equipment will not break. But the food will spoil faster, and odors (for example, herring or onions) will spread throughout the chamber and be absorbed into the plastic.
FAQ: Frequently Asked Questions
How often should you change the filter in the refrigerator?
The standard service life of a carbon filter is from 6 to 12 months. It is recommended to change water filters every 6 months or after filtering 300-500 liters of water, depending on the hardness of the tap water.
Can the carbon filter be washed and reused?
No, carbon filters cannot be washed with water. Water washes away the activated carbon and blocks the pores, after which the filter stops working. You can wash only coarse metal meshes or special washable sponges, if indicated in the instructions.
What to do if the new filter does not fit into place?
Make sure that you have removed all protective films from the new cartridge. Check the orientation (airflow arrows must match). If the filter still does not fit, you may have purchased a model for another series of refrigerators.
Where to buy an original filter?
It is better to purchase original consumables from the brand’s official service centers or authorized partners. The packaging must indicate an article compatible with your refrigerator model.
