Maintaining the interior ventilation system is a critical aspect of vehicle operation, especially in city traffic and high humidity conditions. For owners Nissan Murano second generation (Z51 body), this procedure has its own characteristics, which are often overlooked during scheduled maintenance. A clogged filtration element not only impairs airflow, but also becomes a breeding ground for bacteria, causing unpleasant odors and allergic reactions in passengers.
Many car owners believe that replacing a filter is a simple operation that only requires removing the old element and inserting a new one. However, the design Nissan Murano Z51 is such that access to the filter module is hidden behind a plastic decorative panel, which easily breaks if handled carelessly. Understanding the structure of the case and the correct procedure will save you time and money repairing broken fasteners.
Why replacing the filter on your Murano Z51 is a must
The air entering the crossover interior passes through several stages of purification, and it is cabin filter is the last line of defense against dust, pollen and exhaust fumes. On the model Nissan Murano Z51 The manufacturer installs a filter that effectively traps large particles, but over time its pores become clogged. When you notice that the fan is running at full power and the air flow from the baffles is weak, the problem almost certainly lies in contamination of this element.
Ignoring replacement deadlines leads to increased stress on heater motor. The engine has to work harder to push air through the clogged structure, which can cause it to overheat and fail in the long run. Repairing or replacing the heater motor is an expensive procedure that requires dismantling part of the dashboard, which can be easily avoided by promptly servicing the filter.
In addition to functional problems, a dirty filter becomes a source of unpleasant odors. Moisture accumulating in the pores of the element creates an ideal environment for the growth of mold and fungi. The smell of dampness that appears when you turn on the air conditioner or stove is a sure sign that the element is high time to change. This is especially true for owners who live in regions with rainy climates or often operate the car in urban dust conditions.
Choosing the right consumables for your crossover
Before you get started, you need to decide on the type of filter you will install. For Nissan Murano Z51 There are three main options: paper, charcoal and antibacterial. A paper filter is the cheapest option, which traps dust well, but is not able to neutralize odors. The carbon filter contains activated carbon, which adsorbs harmful gases and odors, making the air in the cabin cleaner and fresher.
The antibacterial option often has a special impregnation that prevents the growth of microorganisms. When choosing, pay attention to original article and high-quality analogues. The original filter from Nissan usually has code 27277-CA000, but there are also proven substitutes from manufacturers like Mann-Filter, Mahle or Corteco, which sometimes surpass the original in filtration area.
- 🔍 Check the packaging for protective holograms and clarity of logo printing.
- ⚡ Consider seasonality: it is better to install carbon filters in the spring before the start of the flowering season.
- 🛠️ If your glasses often sweat, choose filters with increased throughput.
⚠️ Attention: Do not buy cheap filters without markings! They may be the wrong size, causing air to bypass the filtration, or the clamps will not hold, resulting in vibrations and extraneous noise.
Tools and workplace preparation
You don't need complicated special tools or a lift to do this job. The entire process can be done in a garage or even a parking lot with a minimal set of tools. The main condition is access to the glove compartment and illumination of the working area. You will need a PH2 Phillips head screwdriver, a plastic clip remover (to avoid scratching the plastic) and possibly a flashlight as the alcove may be dark.
It is important to prepare a place for the removed parts. The plastic cover and fasteners tend to get lost if you just throw them on the floor. It is best to use a small container or magnetic mat. It is also recommended to wear gloves, as the old filter may be covered with a layer of dust and dirt, which will irritate the skin of your hands.
☑️ Preparing to replace the filter
Step-by-step instructions for dismantling and replacement
The replacement process begins with opening the glove compartment. IN Nissan Murano Z51 The glove compartment opens as usual, but to access the filter it must be lowered as far as possible. You will see stoppers on the sides. Gently press them inward or downward (depending on the modification of the hook) to release the side fastenings and allow the glove compartment to drop below the opening level.
Once the glove box is completely lowered, you will see a plastic filtration cover positioned horizontally. It is secured with several latches and possibly screws. If there are screws, remove them with a screwdriver. If the latches are only latched, use a plastic spatula to carefully pry up the edges of the cover. Be extremely careful: the plastic on older cars becomes brittle.
What to do if the lid does not budge?
If the lid does not budge, do not use brute force. Check for hidden screws under the trim caps or if the glove compartment is not fully lowered. Sometimes the clamps stick over time, and you need to slightly pry them around the perimeter with a spatula, rocking the lid up and down.
When you remove the cover, you will see the old filter. Pay attention to the direction of air flow indicated by the arrows on the body or frame of the old filter. This is critical: the new element must be installed in the same direction. Typically the arrow should point down or towards the heater motor. Pull out the old filter, being careful not to spill any accumulated dirt into the ductwork.
Insert the new filter, observing the airflow direction. Make sure it fits snugly into the grooves and has no gaps around the perimeter. If the filter is difficult to stand up, do not press on it, but check that the orientation is correct. Close the lid by snapping the latches until you hear a characteristic click. Return the glove compartment to its original position by lifting it up and engaging the side stops.
Before installing a new filter, wipe the seat with a damp cloth to remove dust and small debris that may have gotten inside when dismantling the old element.
Common mistakes and how to avoid them
One of the most common mistakes is incorrectly setting the air flow direction. If you place the filter backwards, its efficiency will decrease significantly and the resistance to air flow will increase. In some cases, this leads to the fact that the filter begins to pass dirt directly into the cabin, since the air flow does not pass through a dense layer of material, but flows around it.
Another common problem is damage to the cover latches during dismantling. If you use a metal screwdriver instead of a plastic spatula, the risk of breaking fragile latches increases exponentially. A broken clip causes the lid to rattle while moving or even fall off, which requires the purchase of a new part or complex plastic repairs.
⚠️ Warning: Never attempt to install a filter that does not fit, even if it seems to fit! Incorrect geometry can lead to damage to the heater motor impeller if filter pieces get into the operating unit.

Service times and expert recommendations
Manufacturer Nissan recommends changing the cabin filter every 15,000 - 20,000 kilometers or once a year, whichever comes first. However, in actual use, especially when driving on dusty roads or in a large metropolis with a high concentration of exhaust gases, it is better to reduce the interval to 10,000 - 12,000 kilometers.
Regular replacement is key to the health of your ventilation system. If you notice that the windows begin to fog up faster, or there is a strange noise when the fan is running, do not wait for scheduled maintenance. Carry out a visual inspection of the filter. A clean filter should be light gray or white, without dark spots or damp odors.
Regularly replacing your cabin air filter not only improves indoor air quality, but also extends the life of expensive climate control system components by preventing overheating and contamination of the air conditioning evaporator.
FAQ: Answers to frequently asked questions from owners
How long does it take to replace the filter on a Murano Z51?
The process takes from 10 to 20 minutes for an experienced master and about 30-40 minutes for a beginner who carefully studies the instructions. Most of the time is spent on carefully dismantling the glove compartment and searching for fasteners.
Do I need to change the filter if I can't smell it?
Yes, definitely. Lack of odor does not mean the filter is clean. It can become clogged with dust, which reduces the efficiency of the airflow and increases the load on the stove motor, even if odors are not yet noticeable.
Can I use a filter from another Nissan model?
No, the dimensions and shape of the filter housing are for Nissan Murano Z51 unique. Filters from X-Trail or Qashqai may not be suitable in size or mounting system, which will lead to a loose fit and leakage of unpurified air.
What should I do if I broke the lid lock?
If the latch is broken, the cover may become loose. You can temporarily fix it with plastic clamps or electrical tape, but for a reliable solution it is better to replace the filter cover itself or use universal clips of a suitable size.
