Cabin filter <em>Nissan Murano Z52</em>: when to change, which one to choose and how to replace it yourself

Nissan Murano Z52 is a crossover that is valued for its comfort and reliability, but even in such a car there are parts that require regular attention. One of them is cabin filter, on which the cleanliness of the air in the cabin, the operation of the climate control system and even the health of the driver and passengers depend. Many owners Murano second generation (2015–2022) underestimate the importance of this detail until they encounter foggy windows, unpleasant odors or allergies.

In this article we will look at everything you need to know about the cabin filter for Nissan Murano Z52: how to determine that it is clogged, which filters are best suited (including analogues), how to change it yourself in 15 minutes, and why saving on this procedure can result in expensive repairs to the ventilation system. We will also reveal the myths about “eternal” filters and explain why even original parts from Nissan They don't always justify their price.

Signs of a clogged cabin air filter Murano Z52: when is it time to change

Cabin filter in Nissan Murano Z52 designed for 15–20 thousand kilometers or 1 year of operation (whichever comes first). However, in Russian realities - with dusty roads, smog in cities and frequent temperature changes - this period is often reduced to 10–12 thousand km. How do you know if the filter can no longer cope?

Main symptoms:

• 🚗 Weak air flow from the deflectors even at maximum fan speed. This is the first sign that the filter is clogged with dust and debris.
• 🌫️ Unpleasant smell when you turn on the stove or air conditioner, this is the result of the growth of bacteria and fungus on the wet filter.
• 💨 Constant fogging of windows, especially in rainy weather. A clogged filter impairs air circulation, increasing humidity in the cabin.
• 🤧 Allergic reactions in passengers (sneezing, itchy nose) - the filter stops retaining pollen, spores and small particles.

If you notice at least two of these signs, the filter needs to be replaced immediately. Postponing the procedure is fraught not only with discomfort, but also heater fan failure due to increased load — replacing it will cost 15–20 thousand rubles.

⚠️ Attention: B Murano Z52 with the system Climate Control A clogged filter can cause temperature sensors to fail. The automation will not properly regulate the air flow, which is why the interior will not warm up in winter or cool in summer.

Which cabin filter is suitable for Nissan Murano Z52: original vs analogues

Original cabin filter for Murano Z52 has an article number 27277-JK00A (coal) or 27277-JK00B (regular dust). Cost - from 1,800 to 2,500 rubles, depending on the dealer. But does it make sense to overpay for a brand?

Let's compare the original with popular analogues:

Manufacturer	Article	Type	Price, ₽	Features
Nissan (original)	27277-JK00A	Coal	2 200–2 500	Guaranteed compatibility, high quality materials
Mann Filter	CU 29003	Coal	1 200–1 500	German quality, good filtration of small particles
Bosch	1 987 429 655	Coal	1 100–1 400	Universal option, suitable for most crossovers
Filtron	K 1354A	Coal	900–1 200	Budget option with good reviews
TSN	9.7.861	Dusty	600–800	Minimal protection, suitable only for clean regions

For most owners Murano Z52 the best choice is carbon filters Mann Filter or Bosch. They are 30–40% cheaper than the original, but are not inferior in filtration quality. If you drive on very dusty roads (for example, in rural areas), it is better to give preference multilayer filters with additional protection against pollen (for example, Mann Filter FP 29003).

Step-by-step instructions: how to replace the cabin filter with Nissan Murano Z52 on your own

Replacing the cabin filter in Murano Z52 - one of the simplest procedures that even a beginner can handle. You don't need tools, just your hands and 15 minutes of free time. The filter is located behind the glove compartment, so access to it is open without disassembling the panel.

Algorithm of actions:

1. Open the glove compartment and empty it of its contents.
2. Press the latches on the sides of the glove compartment (they are located inside, closer to the cabin) and lower it down. It will not come off completely, but will simply lower on its hinges.
3. Remove the filter cover — it is secured with two latches. Gently pull it towards you.
4. Remove the old filter. Pay attention to the direction of the arrow on it - the new filter should be installed in the same way.
5. Clean the seat remove dust and debris with a vacuum cleaner or damp cloth.
6. Install a new filter, observing the direction of air flow (indicated by the arrow on the housing).
7. Reassemble everything in reverse order: lid, glove compartment, contents.

If you install a carbon filter, for the first 1-2 days there may be a slight chemical smell in the cabin - this is normal. It will disappear after airing.

⚠️ Attention: Do not attempt to flush or clean the old filter. Even after drying, it loses up to 70% of its filtering properties and becomes a breeding ground for bacteria. Savings of 1,000 rubles can result in a repair of the ventilation system costing 10,000+ rubles.

Top 5 mistakes when replacing the cabin filter with Murano Z52

It would seem, what could go wrong with such a simple procedure? However, even here the owners Murano Z52 manage to make mistakes that ruin all efforts. Let's look at the most common ones:

1. Incorrect installation in the direction of air flow

Each filter has an arrow indicating the direction of air. If you put it “back to front”, the filtration efficiency will drop by 2-3 times, and dust will penetrate into the cabin. B Murano Z52 the arrow should point down (towards the floor).

2. Ignoring footprint cleaning

If you do not remove the accumulated dirt before installing a new filter, it will immediately clog its pores. Use a vacuum cleaner or damp cloth to remove debris from the box.

3. Buying a filter that is the wrong size

B Murano Z52 used filter size 230×200×30 mm. Some analogues (for example, for Nissan X-Trail T32) are similar in appearance, but may not fit tightly, allowing unfiltered air to pass through.

4. Replacing only one filter (if there are two)

In some trim levels Murano Z52 (for example, with a system Plasma Cluster) two filters are installed: main and additional. Skipping the second one will lead to an imbalance of air flows.

5. Use of used filters

Some car owners buy used filters “on occasion”. This is dangerous: mold spores, bacteria and even insects can remain in the pores of such a filter.

What will happen if you do not change the cabin filter: consequences for Murano Z52

Many drivers put off replacing the filter, considering it a “trifle”. However, the consequences can be serious:

1. Heater fan failure

A clogged filter creates additional resistance to air flow, causing the fan to operate at maximum power. B Murano Z52 this often leads to fuse blown (F30, 30A) or motor failure. Average repair cost - 8,000–15,000 rubles.

2. Contamination of the air conditioner evaporator

If the filter does not retain dust, it settles on the evaporator, mixes with condensate and forms slime and mold. This leads to:

• 🦠 The appearance of a persistent smell of rot when the air conditioner is turned on.
• 💧 Deterioration of interior cooling (clogged evaporator cells).
• 🚑 Risk of respiratory diseases among passengers.

Cleaning the evaporator will cost 3,000–5,000 rubles, and in advanced cases it will need to be replaced (up to 30,000 rubles).

3. Malfunctions of climate control sensors

B Murano Z52 with the system Auto A/C A clogged filter can cause false alarms from air quality sensors. The system will randomly switch recirculation modes or refuse to turn on the air conditioner.

How to check the evaporator for mold?

Open the hood and locate the A/C drain tube (the thin rubber tube under the evaporator, usually on the right side). If black or green liquid drips from it, this is a sign of mold. You can also look into the air intake on the passenger side: if plaque is visible on the evaporator honeycombs, cleaning is required.

Myths about cabin filters: what's true and what's not

There are many myths surrounding cabin filters. Let's look at the most popular:

Myth 1: “The carbon filter does not need to be changed, it cleans itself”

❌ Not true. Over time, the coal layer becomes saturated with harmful substances and ceases to absorb them. Moreover, saturated coal begins to highlight back accumulated gases, deteriorating air quality.

Myth 2: “If the filter looks clean, you don’t need to change it.”

❌ Not true. Small particles (pollen, bacteria, soot) are not always visible to the naked eye, but they penetrate the lungs and cause allergies. Even a “clean” filter loses efficiency after 1–1.5 years.

Myth 3: “You can drive without a filter and the air will be cleaner this way”

❌ Danger! Without a filter, not only dust will enter the cabin, but also insects, leaves, and in winter - snow and ice. This will cause the fan to freeze or short circuit.

Myth 4: "Original filters last longer than analogues"

✅ Partially true, but not always. Original filters Nissan Indeed, they have denser material, but their service life depends on operating conditions. In some cases, high-quality analogues (for example, Mann) last longer due to better impregnation.

Myth 5: “The filter should only be changed in the spring, before pollen season.”

❌ Not true. The filter is clogged all year round: in winter - with salt and reagents, in summer - with dust and insects, in autumn - with leaves. It's best to change it every 10–15 thousand km or once a year.

FAQ: Frequently asked questions about the cabin filter Nissan Murano Z52

Is it possible to install a filter from Nissan X-Trail T32 on Murano Z52?

No, despite the external similarity, the filters have different sizes. B X-Trail T32 filter is used 27277-4M00A (240×200×30 mm), whereas in Murano Z52 — 27277-JK00A (230×200×30 mm). Installing the wrong filter will result in gaps and unfiltered air entering.

How often should the filter be changed if the car is parked in a garage?

Even with minimal mileage, the filter ages: the carbon loses its adsorption properties, and the material dries out. It is recommended to replace it once every 1.5–2 years, even if the mileage is less than 10 thousand km.

What is the difference between a carbon filter and a regular one?

The carbon filter, in addition to mechanical dust removal, absorbs harmful gases (exhausts, ozone, benzene) and neutralizes unpleasant odors. A conventional filter only filters large particles. For urban use, the coal option is preferable.

Is it possible to install a HEPA filter instead of a standard one?

Theoretically yes, but in practice it is impractical. HEPA filters have too high resistance to air flow, causing the fan to Murano Z52 will work with overload. In addition, they require frequent replacement (every 5–7 thousand km).

Why did the air in the cabin become weaker after replacing the filter?

Probable reasons:

• The filter is installed incorrectly (the side is reversed).
• The filter cover is not tightly closed, there is a gap.
• The air intake is clogged (for example, with leaves).
• The heater fan is faulty (diagnostics required).

Check the filter installation and contact service if necessary.
