Crossover owners Nissan Murano second generation (Z51 body) are often faced with the need to maintain the interior ventilation system. Long-term operation in conditions of city dust or dusty country roads leads to rapid clogging of the filter element, which reduces the efficiency of the air conditioner and deteriorates the air quality inside the car.
Many car enthusiasts mistakenly believe that replacing this consumable is exclusively a task for the dealership, requiring sophisticated equipment. Actually the replacement procedure cabin filter on Nissan Murano Z51 It is highly accessible and can be performed independently in 15-20 minutes without the use of specialized tools.
Ignoring service intervals can lead to unpleasant odors, fogged windows and even increased wear and tear. heater fan due to increased resistance to air flow. Timely replacement not only improves the microclimate, but also protects the system HVAC from the accumulation of moisture and dirt.
Why do you need to regularly replace the filter and the consequences of ignoring it?
The main task of the filter element is to capture fine dust, plant pollen, fungal spores and other allergens, preventing them from entering the cabin. In dense city traffic Nissan Murano Z51 operates in constant filtration mode, which creates a high load on the system.
If you don't change cabin filter on time, the efficiency of the air conditioner drops by 30-40%. The fan is forced to operate at high speeds in order to pump air through the clogged medium, which leads to overheating of the stove motor and its premature failure.
In addition, bacteria and mold begin to multiply in a clogged filter, causing a specific musty odor that cannot be removed by simple washing. Dust and dirt that has passed through the worn element settles on the air conditioner evaporator, creating an ideal environment for the development of pathogenic microflora.
The condition of the filter is especially critical for people prone to allergic reactions. Clean carbon filter It is capable of trapping not only mechanical particles, but also harmful gases, which is especially important when driving behind trucks in traffic jams.

Choosing the optimal filter model for Nissan Murano Z51
The auto parts market offers a wide range of solutions for crossovers Nissan Murano generation Z51. The manufacturer recommends using original parts, however, there are high-quality analogues that often surpass stock parts in filtration efficiency.
Original filter from Nissan has catalog number 27277-ED00A (or its modifications). It is a regular paper element that copes well with coarse dust, but is less effective against odors and carbon monoxide.
For those who value comfort and health, the best choice will be carbon filter. Its design uses activated carbon, which adsorbs harmful gases and neutralizes unpleasant odors. Brands like Cabin Filter, Knecht or Purflux offer excellent alternatives.
Please note that some owners install filters with antibacterial coating. Such models often have a yellowish tint and contain special additives that inhibit the growth of bacteria inside the element itself.

| Mahle | Combined | Optimal balance of price and quality | 15,000 km |
⚠️ Attention: Avoid purchasing filters with an unknown brand and a suspiciously low price. Cheap materials can disintegrate inside the system, causing a clogged evaporator and costly repairs.
- Once a year (every maintenance)
- Once every six months
- Rarely, only when it smells
- Never changed
Preparatory activities and necessary tools
Replacement process Nissan Murano Z51 does not require dismantling the instrument panel or complex wiring manipulations. All work is performed in the glove box area on the passenger side.
You will need a minimum set of tools. The main tool will be a Phillips screwdriver, since the filter compartment cover is secured with screws. A flashlight is also useful to better illuminate the area behind the glove compartment.
Before starting work, make sure that the vehicle is turned off and the ignition key is in the OFF. This is necessary for safety and to prevent accidental activation of the ventilation system during dismantling.
If you plan to clean the filter housing, prepare a vacuum cleaner and a damp cloth. This will remove accumulated dust and leaves, which often accumulate in the niche behind the old element.
- ✅ Phillips screwdriver (medium or small)
- ✅ New filter element
- ✅ Flashlight to illuminate the work area
- ✅ Vacuum cleaner for cleaning the niche (optional)
☑️ Preparation for replacement
Step-by-step instructions for dismantling and replacing the element
To access cabin filter You must first vacate your place of work. Open the glove box and locate the opening stops on the sides. Press on them so that the box drops as far as possible, taking a horizontal position.
You will see several screws on the inside of the filter compartment cover, located behind the glove box. Unscrew them with a screwdriver and carefully remove the plastic cover. It may be held in place by clips, so be gentle to avoid breaking the plastic.
Remove the old filter. Pay attention to the direction of the air flow arrows drawn on its body. This is critical: the new filter must be installed exactly the same, otherwise its effectiveness will be reduced to zero.
Insert the new element into the grooves, making sure that it fits snugly against the edges of the housing. Make sure that the rubber sealing frame of the filter is not twisted or pulled out of the seat.
Направление стрелки: ВНИЗ или ВПЕРЕД (в зависимости от маркировки)Replace the plastic cover and tighten the screws. Lift the glove box until the latches click. Check the operation of the ventilation system by turning on the fan at maximum speed.
⚠️ Attention: If you install the filter backwards, the air will stop passing through the filter layer, and dust will settle directly on the air conditioner evaporator.
What should I do if the lid does not close? If the lid does not close completely, the filter may be too thick or not installed correctly. Check to see if the sealing rubber is sticking out of the body.-->
The nuances of working with carbon and multilayer filters
When choosing carbon filter for Nissan Murano Z51 it is worth considering its design features. These filters often have a denser structure, which can slightly reduce airflow compared to their paper counterparts.
Multilayer models consisting of synthetic fiber and carbon require more careful handling during installation. Their edges can be fragile, so when inserting them into the case, avoid pressing the ends too hard.
Some owners prefer to combine filter types
install carbon filter for the winter to protect against exhaust gases, and for the summer - regular paper for better air circulation. However, this is not a requirement.
If you feel that the odor protection has weakened, the filter must be replaced, even if it appears visually clean.
Common errors when servicing the system
One of the most common mistakes is installing a filter without taking into account the direction of air flow. There is always an arrow on the body indicating where the air should blow. If you put the element in reverse, it will cease to perform its functions.
Another mistake is ignoring niche cleaning. After removing the old element, leaves, dust and small branches often accumulate in the compartment. If they are not removed, they will enter the ventilation system, causing extraneous noise and odors.
Some car owners try to extend the life of the filter by trying to wash it or vacuum it. For disposable filters this is unacceptable: the fiber structure is destroyed and the cleaning efficiency drops to zero.
You should also avoid installing filters that are not the right size. Even a slight deviation in width will cause some of the air to bypass the filter, bypassing cleaning.
- ❌ Installation without taking into account the direction of the flow arrow
- ❌ Attempting to rinse or clean a disposable filter
- ❌ Ignoring cleaning the footprint from debris
Correct orientation of the filter along the air flow arrow is a key factor in the efficiency of the air conditioning system.
Replacement frequency and operating conditions
Official regulatory replacement Nissan recommends maintenance cabin filter every 15,000 - 20,000 kilometers or once a year, whichever comes first.
However, actual operating conditions often dictate their own rules. If you drive mainly in a city with heavy traffic or on dirt roads, the interval should be reduced to 10,000 kilometers.
During the flowering period of plants or if there are allergy sufferers in the family, replacement should be carried out more often - every 6 months. This will ensure maximum air purity and comfort for passengers.
Pay attention to the smell in the cabin. If a smell of dampness or dust appears when you turn on the ventilation, this is a sure sign that the filter requires immediate replacement, regardless of mileage.
⚠️ Attention: In conditions of high humidity and frequent rain, the filter may become saturated with moisture, which will lead to mold. In this case, replacement is required immediately.
Frequently asked questions from Nissan Murano Z51 owners
Is it possible to install a filter without a carbon layer if it was with carbon?
