Modern household appliances are becoming smarter and more complex, acquiring additional functions that are designed to make life easier for the owner. One such option is an air or water purification system, the operation of which requires regular replacement of consumables. Many users encounter difficulties already at the first stage of maintenance, not knowing exactly where the refrigerator filter is located in their specific model.
The location of this element directly depends on the manufacturer, year of manufacture of the device and its design features. In some cases, access to it is open and obvious, in others it requires dismantling decorative panels or removing back covers. Understanding the structure of your unit will help you quickly find the right unit and avoid accidental damage during maintenance.
In this article we will analyze all possible options for placing filter elements, consider the differences between water and air purification systems, and also give practical advice on replacing them. Regardless of whether you own an old Soviet model with a simple system or the latest Smart refrigerator, you will find useful information here.
Main types of filters in refrigeration equipment
Before you start your search, you need to clearly understand which element you are interested in, since their functions and installation locations are radically different. Modern refrigerators can use two main types of filtration systems, each of which solves its own unique problems in maintaining the microclimate and food quality.
The first and most common type is carbon filterdesigned to clean the air inside the chambers. Its main task is to absorb unpleasant odors emitted by products and prevent them from mixing. For example, the aroma of fish should not penetrate into the milk compartment, and the smell of onions into the fruit compartment.
The second type is a water filtration system, which is installed in models with a dispenser or an ice maker. Here we are talking about more complex cartridges that remove chlorine, heavy metals and mechanical impurities. Important: carbon filters for air and cartridges for water are not interchangeable elements and have different designs.
It is also worth noting the existence of antibacterial coatings, which are often confused with replaceable filters. They can be applied to the internal walls or be static plates with silver ions, which do not require frequent replacement, unlike bulk carbon cassettes.
Localization of a carbon deodorizer in various models
If your goal is to find an air purification element, then in most cases the search will take no more than a minute. Manufacturers try to make these elements as accessible as possible, since they are consumables that require regular replacement every 6–12 months.
Most often deodorizer located on the back wall of the refrigerator compartment. This is a classic solution for models Liebherr, Bosch, Siemens and many other European brands. Usually it is closed with a decorative plastic cover with perforations, which needs to be turned counterclockwise or simply pulled towards you.
In some models, especially in refrigerators with a system No Frost, the filter can be built directly into the ventilation unit. In such cases, it is accessed through the top of the refrigerator compartment, where the air ducts are located. Sometimes this requires removing the plastic ceiling panel.
⚠️ Attention: In older models or budget series, the carbon filter can be presented in the form of a small plastic container with granules, which is simply inserted into a special groove on the rear wall without additional fasteners.
Refrigerators with a double air circulation system deserve special attention. They can have two filter elements installed: one in the refrigerator compartment, the other in the freezer. This provides better cleaning and prevents the transfer of odors between compartments even when the doors are opened.
Where to look for a water filter: dispensers and ice makers
Finding a water filter is a more difficult task, since manufacturers hide it in different places so as not to violate the aesthetics of the design and save internal space. The installation location depends on whether the filter is built-in or remote, as well as on the brand of the device.
In American-type refrigerators with a dispenser on the door, the cartridge is most often located in the lower right corner of the refrigerator compartment. It is hidden behind a removable decorative grille in the basement. To access, simply pull the handle or press the lock button, after which the cartridge is removed by turning.
Another popular placement option is the upper right corner of the refrigerator compartment. This is typical for many models Samsung, LG, Whirlpool. In this case, the filter looks like a horizontally or vertically mounted cylinder, which is unscrewed or removed by moving towards itself after unlocking.
There is also an option for location in the technical compartment. In some built-in models or refrigerators with thin walls, the filter may be located in a niche above the refrigerator compartment (the top cover must be removed) or even in the plinth at the front, behind a decorative strip near the floor.
| Brand | Typical location | Removal mechanism | Resource (liters) |
|---|---|---|---|
| Samsung | Upper right corner inside | Press the button and turn | up to 3000 |
| LG | Upper right corner inside | Rotate counterclockwise arrows | up to 2500 |
| Whirlpool | Bottom base or corner inside | Unscrewing | up to 4000 |
| Bosch/Siemens | Bottom right (behind the grille) | Rotate and remove | up to 5000 |
If you do not find a filter inside the chambers, check the space behind the refrigerator. In some cases, especially in older models with a water supply connection, a remote cleaning system is used, installed on the water supply pipe immediately before entering the unit.
Specific location in refrigerators of different brands
Each manufacturer strives to implement its own engineering solutions, which leads to diversity in design. Knowing the characteristics of a particular brand can significantly reduce search time. Let's look at the nuances of popular brands.
In technology Indesit i Hotpoint-Ariston the deodorizer filter is often located in a special recess on the back wall, closed with a lid with the "Anti-Bacteria" or "Fresh" logo. No tools are needed for access, just turn the lid.
Refrigerators Electrolux and Zanussi can be equipped with a Twin Tech system, where the air filter is integrated into the multi-flow cooling system. In such cases, it may be located in the air supply duct, which can be accessed after removing the shelf or drawer.
What to do if the filter is not found?
If a visual inspection does not produce results, it is possible that your model uses a static adsorbent that does not require replacement, or there is no filtration system. Check the user manual to clarify the configuration.
In premium models LG InstaView or Samsung Family Hub combined systems are often used. The water filter may have a resource indicator on the display, and the cartridge itself may be located in a hard-to-reach place, requiring removal of the side panel or bottom of the freezer.
It is worth remembering that in two-compressor models, each circuit may have its own characteristics. A freezer with a system No Frost is often equipped with its own independent deodorizer, which is located next to the evaporator.
Signs of contamination and the need for replacement
Understanding where the filter is is useless if you don't know when it needs to be changed. Ignoring the timing of replacement can lead not only to the appearance of unpleasant odors, but also to increased energy consumption or breakdown of the compressor due to impaired air circulation.
The main sign of resource depletion charcoal filter is the appearance of persistent foreign odors inside the chambers, even if the products are fresh. If you feel the aroma of missing vegetables a day after they were removed, it means that the sorbent is oversaturated and has stopped working.
For water filters, the signal is a change in the taste of the water or a decrease in the speed of filling the glass from the dispenser. Also, on the display of modern models, the indicator often lights up Filter Reset or the corresponding icon blinks, indicating the end of the cartridge's service life.
- 👃 The appearance of mixed odors (fish smells like lemon, meat smells like herbs).
- 💧 The water from the dispenser has become cloudy or acquired the taste of chlorine.
- ❄️ Formation of excessive amounts of ice in the freezer (due to circulation problems).
- 🔊 Increased fan noise (a clogged filter creates air resistance).
The average service life of a carbon filter is from 6 to 12 months, depending on how often the refrigerator is used and the amount of strong-smelling food stored. Water cartridges are designed to hold a certain volume of liquid, usually from 2000 to 5000 liters.
⚠️ Attention: If the indicator on the control panel does not go off after replacing the filter, you must perform a reset procedure. This is usually done by long pressing (3-5 seconds) on the "Filter" button or through the settings menu in the section
Service.
Instructions for replacement and maintenance
The filter replacement process usually does not require special skills or tools, but requires compliance with a certain sequence of actions. Violation of the technology can lead to leaks (in the case of water systems) or loose fitting of the cover.
Before starting work, be sure disconnect the refrigerator from the power supplyif the instructions require removing the panels behind which the electrical components are located. To replace the air filter, this is often not required, but for a water filter it is highly desirable to avoid a short circuit in case of accidental ingress of water.
☑️ Algorithm for replacing the filter
When installing a water cartridge, it is important to remove the protective caps from the seals immediately before insertion. Do not touch the rubber gaskets with dirty hands, as this may damage the seal of the connection. After installation, run 2-3 liters of water through the system to remove air pockets and coal dust.
If you are replacing a carbon deodorizer, make sure that the protective film (if there is one on the new element) is removed. Install the filter strictly in the same position as the old one was installed, observing the orientation of the airflow arrows, if they are indicated on the housing.
After completing the procedure, close all panels and turn on the refrigerator. Give the system 2-3 hours to return to operating mode and stabilize the temperature before loading the food back in full.
Frequently asked questions (FAQ)
Can the carbon filter be washed and reused?
No, this is strictly not recommended. When washed with water, the carbon structure loses its adsorbing properties, and when dry, it can begin to crumble, getting into the ventilation system. In addition, wet coal becomes an ideal environment for the growth of bacteria.
What will happen if you do not change the water filter for a long time?
After time, it will stop purifying the water, and the accumulated contaminants will begin to be washed back, deteriorating the quality of drinking water. The flow resistance will also increase, which will create an extra load on the dispenser pump and can lead to its breakdown.
Where to buy an original filter if it is not available in stores?
Original consumables are often sold only in authorized service centers or on the official websites of manufacturers. However, there are high-quality compatible analogues from third-party manufacturers that are suitable in size and characteristics.
How often do you need to change the filter in a refrigerator with No Frost?
For No Frost systems, it is recommended to change the carbon deodorizer every 6 months, since active air circulation saturates the coal with odors faster. In conventional drip systems, the resource may last for a year.
Can a refrigerator work without a filter at all?
Yes, technically a refrigerator will work without a filter. However, with water systems, this can cause scale to clog the thin ice maker tubes. Without an air filter, odors will simply be absorbed into food faster.
