The air in a car is not just about comfort, but a matter of safety and health for the driver and passengers. For crossover owners Nissan Murano this topic becomes especially relevant given the dimensions of the body and frequent trips both around the city and outside it. A dirty cleaning element can turn even the most modern climate control into a source of unpleasant odors and allergies.
Many car owners ignore routine maintenance of the ventilation system until they feel obvious discomfort. However, timely replacement cabin filter is a simple procedure that requires a minimum of time and tools. A properly selected consumable will ensure clean air, protect the air conditioner evaporator from mold and extend the service life of the entire ventilation system.
Types of air purifiers for crossovers
There are several types of filter elements on the auto parts market that are suitable for different generations of the model. Nissan Murano. The choice depends on your priorities: maximum savings, basic protection or advanced cleaning from odors and allergens. Manufacturers offer both simple paper products and complex multilayer structures with activated carbon.
Standard paper filter made from special corrugated paper impregnated with resins. Its main task is to trap large dust, fluff and insects, preventing them from getting into the air ducts. This option copes well with mechanical particles, but is completely powerless against toxic exhaust gases or pungent odors, which are often found in city traffic.
Carbon modification is an improved solution where a layer of activated carbon is placed between layers of paper. This material has a porous structure that effectively adsorbs molecules of gases and unpleasant odors. For Nissan Murano with its spacious interior use carbon filter is the most rational choice for year-round use.
There are also combined options equipped with an electrostatic charge or ionization additives. They are able to attract the smallest particles of dust that usually pass through ordinary paper. When purchasing, it is important to pay attention to the density of the material and the thickness of the product, since an element that is too thin will quickly clog, and an element that is too dense can restrict the air flow.
- 🌫️ Paper type - basic protection against dust and dirt, low cost.
- 🛡️ Coal type - protection against gases, odors and allergens, high efficiency.
- 💨 Electrostatic type - retention of the smallest suspended particles.
When is it necessary to replace
Manufacturer Nissan recommends replacing the air purification element every 15,000 kilometers or once a year, whichever comes first. However, actual operating conditions often dictate their own rules. If you live in a metropolis with high gas pollution or often drive on dirt roads, the interval is reduced to 7-10 thousand kilometers.
There are clear signs indicating that the filter has reached the end of its life and requires immediate replacement. Ignoring these symptoms may result in reduced fan performance and condensation on the windshield. Regular diagnostics of the condition of the ventilation system should become part of your usual car care.
The first alarm bell is the appearance of foreign odors, especially when the heating or air conditioning system is turned on. If you feel mustiness or a burning smell, this is a sure sign that moisture has accumulated in the pores of the element and bacteria have begun to multiply. In such cases, replacement cabin filter must be carried out without delay.
Also pay attention to the intensity of the airflow. If the air flow from the deflectors has become noticeably weaker, even at maximum fan speed, the flow sections are most likely clogged with dirt. This creates an extra load on the stove motor, which can fail due to overheating.
⚠️ Warning: A dirty filter can cause mold to form inside the air conditioner evaporator, which will lead to costly repairs to the climate control system.
Another indicator is frequent fogging of windows in wet weather. A clogged element does not allow moisture to be effectively removed from the interior, causing the glass to become covered with condensation, impairing visibility. This creates a direct threat to traffic safety, especially at night.
Installation location and access to the element
Construction Nissan Murano provides for the installation of an air purifier in a niche under the glove compartment on the front passenger side. Access to this unit is quite simple and does not require disassembling the center console or using complex diagnostic equipment. All you need is a small Phillips screwdriver and maybe a plastic spatula.
The process begins with opening the glove compartment. To gain access to the filter cover fasteners, you need to empty the glove compartment of unnecessary items and press the opening limiters. In some modifications of the crossover, it is necessary to dismantle the shelf itself by unclipping the latches on the sides.
After removing the cover, you will see the filter housing, which can be closed with a plastic plug or immediately have a removable cover. It is important to remember or photograph the position of the airflow arrow, indicating the direction of air flow, so that when installing a new product you will not make mistakes. Incorrect orientation can compromise aerodynamics and reduce cleaning efficiency.
Some owners are faced with the fact that the filter housing fits tightly to the body elements, which makes it difficult to remove the old product. In such cases, you should not use excessive force to avoid breaking the plastic latches. By gently rocking the filter, you can release it from the clamps.
- Every maintenance
- Once a year
- Only when it stinks
- I forgot when was the last time I changed it
Step-by-step replacement instructions
To complete the replacement procedure, you do not need to contact a service center, since the process takes no more than 15 minutes. Prepare a new one filter element, corresponding to your model, and a set of simple tools. Make sure you work in a well-lit area to avoid losing small details.
Start by disconnecting the battery terminals, although this is not strictly necessary, it is recommended to prevent accidental operation of the electronics. Open the glove compartment lid and press the side stops to lower the shelf all the way down. If there are latches on the filter cover, carefully press them out with a screwdriver.
Remove the old element and carefully inspect it for any accumulation of large debris, leaves or branches that may be stuck in the housing. Wipe the interior with a dry cloth or use a vacuum cleaner to remove dust. This is an important step that is often missed, resulting in rapid contamination of the new product.
Install the new filter, following the direction of the airflow arrow. The arrow should point down or to the side corresponding to the direction of air movement in the system. Close the filter cover until the latches click and return the glove compartment to its original position.
☑️ Replacement tools
After installation is complete, check the operation of the ventilation system. Turn on the air conditioner and make sure that the air flow has become stronger and the foreign odors have disappeared. If you did everything correctly, the system will work silently and efficiently.
What should I do if the filter doesn't fit?
If the new filter does not fit into the housing, check its model. Sometimes manufacturers change dimensions, and the standard element may not fit. Try to squeeze the filter housing slightly, but do not use brute force to avoid damaging the plastic.
Comparison of popular brands and items
Choosing a filter manufacturer is a balance between cost and filtration quality. Original Nissan always guarantees a perfect fit and the stated characteristics, but is often more expensive than its analogues. However, many third-party brands offer products that are as effective as factory parts.
Among the popular manufacturers are Mann-Filter, Mahle and Blue Print. These companies use high-quality materials and strictly adhere to production technology. Their products often surpass the original in filtration density and durability, especially in Russian road conditions.
Budget options from Chinese manufacturers may be attractive due to their low prices, but their quality often leaves much to be desired. The paper may be too loose, allowing dust to pass through, or the charcoal layer may not be applied evenly. Saving on such an element may result in repairs to the ventilation system in the future.
The table below shows the main articles for different generations Nissan Murano, which will help you find the right product in the spare parts store. Always check your vehicle's VIN when purchasing, as design changes may affect the filter type.
| Generation | Years of manufacture | Original article | Analogue (Coal) | Analogue (Paper) |
|---|---|---|---|---|
| Z50 | 2003–2007 | 27891-ED000 | Mann CU 21004 | Mann C 21004 |

When purchasing, pay attention to the packaging: a high-quality product has clear printing, protective holograms and detailed instructions in Russian. Avoid products with damaged packaging or signs of tampering, as the integrity of the filter may have been damaged during transportation.
⚠️ Attention: Do not buy filters without markings or at a suspiciously low price - they may be fakes that do not adequately protect your health.
Features of care and operation
To extend the life of the filter, it is important to follow the operating rules of the vehicle. Do not turn on air recirculation for a long time in conditions of heavy gas pollution, as this can lead to the accumulation of harmful substances in the cabin. Alternate the modes of air intake from the street and recirculation for ventilation.
If you often drive on dusty roads, it is recommended to inspect the filter more often than scheduled. A simple visual check through a gap in the body or with the glove compartment open will help identify the need for replacement in time. Do not wait for odors to appear, as by this time the filter may already be completely clogged.
In winter, make sure that no moisture gets into the filter housing. Condensation buildup can cause moisture inside the filter to freeze and block airflow. Make sure that the drainage system under the vehicle is not clogged to prevent water from entering the air intake area.
The use of stick-on or spray-on fragrances is not a substitute for high-quality air purification. On the contrary, they can mask unpleasant odors, hiding the problem of a dirty filter. It is better to take the time to replace the element rather than rely on artificial scents.
Before installing a new filter, lightly wipe its surface with a damp cloth to remove any possible factory dust, but do not wet the carbon layer!
Regular replacement is the key to not only clean air, but also the longevity of the entire climate control system. A clean filter reduces the load on the heater motor and air conditioner evaporator, preventing their premature wear. This is a simple investment in comfort and safety that pays off handsomely.
Using a high-quality carbon filter and timely replacement is the best way to protect the health of passengers and extend the life of the Nissan Murano ventilation system.
Ignoring the condition of the filter can lead to serious consequences, including the breakdown of expensive components. Therefore, treat this element with due attention and do not put off replacing it until later. Your car will thank you with clean air and reliable operation.
Frequently asked questions from owners
Can the cabin filter be washed and reused?
No, you absolutely cannot wash or reuse the filter. Paper fibers are destroyed by water, and the carbon layer loses its adsorbing properties after getting wet. Repeated use of such an element may result in dirt and bacteria entering the interior, as well as damage to the fan.
What should I do if there is a smell after replacing the filter?
If the smell appears immediately after replacement, you may have installed a low-quality filter or did not clean the housing of old dust and debris. Also check if the airflow arrow is installed correctly. In some cases, the odor may be due to a dirty air conditioner evaporator, which requires professional cleaning.
Is it possible to install a larger filter for better filtration?
Installing a larger filter is impossible without structural changes to the housing. The filter must fit snugly against the walls of the niche, otherwise air will bypass the filter element, making it useless. Use only parts that match factory dimensions.
How long does it take to replace a filter?
The replacement process takes from 10 to 20 minutes. This is one of the simplest car maintenance procedures that does not require special skills or complex tools. Most owners can do this work themselves in a garage or parking lot.
Does the filter affect fuel consumption?
The filter does not have a direct effect on fuel consumption, since it purifies the air only for the cabin. However, a severely clogged filter can put a strain on the blower motor, which increases the generator's power consumption slightly, but the effect is negligible for overall fuel consumption.
