Fresh air in the cabin is not just comfort, but a guarantee of your health and safety while driving. Nissan Murano is famous for its spaciousness and quiet running, but the ventilation system requires regular attention. Many owners forget about the filter until a weak stream begins to blow from the deflectors or an unpleasant damp smell appears.
The replacement procedure does not require complex equipment or a visit to a service center. However, depending on the generation of your crossover, access to the item may vary. For models Z50, Z51 and new Z52 There are some installation subtleties. Ignoring routine maintenance leads to rapid contamination of the air conditioner evaporator and increased load on the climate control system fan.
Why change the filter and when is it necessary?
The cabin filter functions as a barrier that traps dust, pollen, mold spores and exhaust gases entering the cabin through the air intake system. In city conditions, where the concentration of pollution is high, the paper element becomes clogged within 10-15 thousand kilometers. Dirty filter stops passing air, which is why the air conditioner idles, not cooling the interior to the desired temperature.
The critical moment is the appearance of mold. If you smell a musty smell when you turn on the ventilation, it means moisture has accumulated in the pores of the old element. In such a situation, one replacement is not enough; you will also need air duct disinfection. Experts recommend changing consumables every 15,000 km or once a year if the car is used in rural areas with a lot of dust.
It is important to understand the difference between a regular and a carbon filter. Ordinary paper element traps only large particles. The carbon version contains a layer of activated carbon that adsorbs gases and odors. For Nissan Murano In the city, it is better to choose carbon filters, as they more effectively protect against the exhaust gases of other cars in traffic jams.
⚠️ Attention: Do not attempt to blow out or rinse the old filter with water. This is not helpful and may cause the material to rupture or mold to grow inside the element, making the situation worse.
This is especially true for owners of cars with the system Automatic Climate Control. Air quality sensors may not work correctly when there is heavy pollution, switching modes too often or, conversely, not responding to environmental pollution.
Selection of original and analog filters
There are many options on the market and choosing the right item can be difficult. Original filter from Nissan (part number 27277-4XA0A or 27277-JA00A depending on the year) guarantees perfect fit and filtration quality. However, its cost is often overpriced compared to high-quality analogues.
Among the popular replacement brands, it is worth highlighting Mahle, Cabfil, Denso and Pilenga. These manufacturers offer products that often surpass the original in dust retention quality. For example, a filter from MAHLE LA series has an improved fiber structure, which extends service life.
- 🏆 Denso — Japanese quality, excellent air throughput.
- 🛡️ Cabfil — affordable price, good carbon layer in versions with activated carbon.
- 💎 Sakura - a popular budget option, suitable for replacement once a year.
When purchasing, be sure to pay attention to the labeling. For Murano For the Z50 generation, the filter has one shape, but for the Z51 and Z52 it may differ. An error in selection will result in the element not falling into place or allowing air to pass through the filtration.
Comparative characteristics of popular analogues will help you navigate when choosing:
| Brand | Filter type | Service life (km) | Feature |
|---|---|---|---|
| Nissan (Original) | Coal | 15 000 | Ideal geometry |
| Denso | Coal | 20 000 | High efficiency |
| MAHLE | Paper | 15 000 | Maximum throughput |
| Sakura | Coal | 10 000 | Budget segment |
- Once a year
- Once every 15 thousand km
- Only when it smells
- I don't know when to change
Tools and preparation for work
Before starting work, you need to prepare a minimum set of tools. For most models Nissan Murano you don't need specialized wrenches or torque tools. The main task is to carefully remove the decorative panels and unscrew the filter cover fasteners.
You will need a flathead screwdriver with a thin blade to pry the fasteners. A PH2 Phillips screwdriver is also useful for removing screws. Some owners use a plastic card or putty knife to avoid scratching the plastic when removing the panels. Vacuum cleaning before replacement is an important step to prevent dirt from getting inside the system.
- 🔧 Phillips screwdriver — for the cover fastening screws.
- 🪄 Flat head screwdriver — for removing latches and decorative plugs.
- 🧹 Vacuum cleaner - to clean the niche before installing a new element.
It is better to carry out work in a clean room or garage. Outdoors is not suitable as dust and insects may get into the open ducts during the replacement process. Warming up the car It is not required before work, but if the interior is very dusty, it is better to wear a respirator.
☑️ Preparation for replacement
Replacement for Nissan Murano Z50 (2002-2007)
In the first generation of the crossover, access to the filter is through the glove compartment (side glove box). This is a classic design for many cars of the time. You don't have to remove the entire torpedo, just free up some space inside the box.
Open the glove compartment and lower it all the way down. On the sides you will see travel stops. They need to be carefully squeezed and the glove compartment lowered even lower until it hangs on its hinges. At the back of the box you will see a plastic lid secured with several latches.
To remove the cover, press the latches. They can be located around the perimeter or just on top. Be careful, plastic can be brittle due to aging. After removing the cover you will see the old filter. Remember the airflow directionindicated by the arrow on the body to install the new element correctly.
Remove the old element and thoroughly vacuum the niche. In old Murano Z50 Leaves and dust often accumulate there, which can get into the evaporator when installing a new filter. Check the condition of the air ducts for damage.
Installation Features in Z50
If the filter does not fit, check to see if the edges of the housing are bent. Sometimes debris gets into the niche and interferes with the installation. Gently wipe the niche with a damp cloth before installing the new element.
Procedure for Nissan Murano Z51 (2008-2014)
Second generation Nissan Murano received a more complex filter mounting system. Access is also through the glove compartment, but the locking mechanism has become more reliable. On some trims, the filter is located under the instrument panel on the passenger side, requiring removal of the lower panel.
To begin, lower the glove compartment, as in the previous case. However, in the Z51 it is often necessary to remove the lower trim panel under the glove compartment. It is held on by clips. Carefully pry it off with a flathead screwdriver. Be careful not to break the fasteners as they may be fragile.
After removing the cover you will see the filter cover. It is secured with screws or latches. Unscrew the fasteners and remove the cover. Remove the old filter. Please note that in Z51 a filter of increased area is often used, so its shape may differ from its predecessor.
Install the new element, observing the direction of air flow. The arrow should point down or towards the evaporator, depending on the design. Don't mix up the sides, otherwise the filtration efficiency will drop sharply and the resistance to air flow will increase.
Before removing the cover on the Z51, take a photo of the location of the old filter. This will help avoid installation errors if the markings are erased.
Replacement nuances in Nissan Murano Z52 (from 2015)
The third generation of the crossover features a modern interior design and more sophisticated ergonomics. Access to the filter in Murano Z52 also carried out through the glove compartment, but the design of the box has become more complex. The glove compartment has a double opening mechanism and may require additional manipulations for complete dismantling.
In some versions of the Z52, the filter is located not behind the glove compartment, but behind the instrument panel on the passenger side. This requires removing the bottom panel. To do this, you need to unscrew the fastening screws and carefully remove the panel by unfastening the clips. Be extremely careful with sensor wiring if there are any in the dismantling area.
The filter cover on the Z52 is often a complex shape and is secured with Torx or Phillips head screws. Unscrew them and remove the cover. Remove the old filter. Newer models often use filters with a denser structure, so do not use excessive force when installing.
Install the new filter, making sure it fits snugly into the housing. Tightness connections are critical. If there are gaps between the filter and the housing, unfiltered air will enter the cabin, negating the effectiveness of the replacement.
⚠️ Attention: On the Z52, be careful with the airbag wiring when removing the panel. Improper handling may result in an SRS error on the dashboard.
After installing all the parts, return the glove compartment and lower panel to their place. Make sure all latches click into place. Turn on the air conditioner and check the ventilation operation. If the air flow becomes stronger and the smell disappears, the job is done successfully.
On Z52 models, it is critical to check the tightness of the filter fit, since the housing design has complex bends.
Common mistakes and how to avoid them
Many owners make common mistakes when replacing the filter. The most common is incorrect element orientation. If you place the filter backwards, not only will it not clean the air, but it will also create additional resistance, forcing the fan to work at its limit.
Another mistake is using the wrong size filters. Cheap analogues often have inaccurate geometry. If the filter is “dangling” in its seat, some of the air will pass past it, taking dust and dirt with it. In this case, it is better to use the original element or a high-quality analogue with an accurate pattern.
- ❌ Ignoring airflow arrow — leads to rapid contamination of the evaporator.
- ❌ Poor niche cleaning - old dust and leaves enter the ventilation system.
- ❌ Saving on quality — cheap filters are destroyed by air pressure.
Also, don’t try to “fit” the filter with scissors if it doesn’t fit. This can compromise the integrity of the filter material and lead to leaks. If the filter does not fit, check to see if you forgot to remove the protective film or if you have the wrong model.
Another problem is damage to the filter housing during dismantling. Plastic becomes brittle over time, especially in hot climates. Act carefully, do not use brute force. If the latch is broken, it can be replaced or fixed with tape, but it is better to find a new housing.
Ventilation system maintenance
Replacing the filter is only part of maintaining the ventilation system. To maintain it in perfect condition, it is recommended to periodically evaporator disinfection. This is especially true for air-conditioned cars that sit idle in traffic jams.
You can use special aerosols to clean the air conditioner. They are sprayed through a drainage hole or through deflectors. The procedure allows you to destroy bacteria and mold, which can cause unpleasant odors even with a new filter. However, if the smell does not go away after replacing the filter, the problem may be deeper.
It is also worth checking the operation of air recirculation. If the damper is stuck in the “fresh air” position, more dust will enter the cabin. Regularly checking the operation of all ventilation modes will help avoid problems in the future. Climate control system requires attention just like the engine.
Don't forget that a clean filter improves the performance of your heating system in winter. If the filter is clogged, the evaporator coil will not warm up properly and the cabin will heat up more slowly. This is especially important in the cold season, when passenger comfort depends on the speed of warming up.
⚠️ Attention: If the smell does not disappear after replacing the filter, moisture may have accumulated in the ventilation system and mold has formed. The evaporator requires professional cleaning.
Results and recommendations
Replacing the cabin filter with Nissan Murano is a simple but important procedure that affects health and comfort. Regular replacement every 15,000 km will help avoid problems with the air conditioner and extend the life of the ventilation system. Don’t skimp on the quality of consumables, choose proven brands.
Remember that access to the filter differs in different generations of the crossover. Carefully study the features of your model before starting work. If you are not confident in your abilities, it is better to entrust the work to professionals, but in most cases this procedure can be performed independently.
Monitor the condition of the filter, especially during the flowering season or dust storms. Timely replacement will save you money on air conditioning system repairs and provide fresh air in the cabin. Your health depends on the quality of the air you breathe.
