Replacing the cabin filter on a Nissan Murano Z51: instructions with photos and videos

Cabin filter in Nissan Murano Z51 is not just a consumable, but a key element that affects the comfort and health of the driver. Over time, it becomes clogged with dust, pollen, bacteria and even exhaust fumes, turning into a breeding ground for allergens. If you notice that there is an unpleasant odor in the cabin and the air conditioner is working less efficiently, it’s time to act.

In this article we will look at how to replace the cabin filter with Murano Z51 with your own hands, without resorting to services. You will learn what tools you will need, how to choose a quality filter, and avoid common mistakes. And also - unique life hacks, which will save your time and nerves.

When should you change the cabin air filter on your Murano Z51?

The manufacturer recommends replacement every 15,000–20,000 km or once a year. But in real conditions this interval can be halved. For example, if you often drive on dusty roads, in traffic jams, or in regions with high humidity, the filter will wear out faster.

Here are clear signs that it's time to act:

• 🚗 Weak air flow from the deflectors even at maximum fan speed.
• 🤧 Constant dustiness in the cabin, even after cleaning.
• 🌫️ Fogging of windows for no apparent reason (especially in the rain).
• 👃 Unpleasant smell when you turn on the air conditioner or heater.

If you ignore these symptoms, the consequences may be more serious than you think. A clogged filter increases the load on the ventilation system, which leads to stove motor overheating and even a breakdown of the climate system. And the accumulation of moisture in the filter is an ideal environment for mold, which then spreads through the air ducts.

⚠️ Attention: If in your Murano Z51 installed carbon filter, its resource is even less - about 10,000 km. Charcoal loses its adsorbing properties faster than a regular paper filter.

Which cabin filter to choose for Nissan Murano Z51?

There are three types of filters on the market:

• 📄 Paper (dust) - the cheapest, but only retain large particles.
• 🖤 Coal - absorb harmful gases and odors, but are more expensive and require frequent replacement.
• 🔬 Electrostatic - attract fine dust and allergens, often reusable (can be washed).

For Murano Z51 Filters with catalog numbers are suitable:

Filter type	Original number	Analogues (brands)	Average price, ₽
Paper	27277-4M00A	Mann CU2939, Bosch 1987432464, Framm CF10134	800–1 200
Coal	27277-4M01A	Mann CUK2939, TSN 9.7.820, Sakura CA-1839	1 500–2 500
Electrostatic	—	Knecht LA939, Mahle LAK939	2 000–3 500

If you suffer from allergies or often drive in traffic jams, it is better to choose carbon or electrostatic filter. They more effectively purify the air from harmful impurities. For normal operating conditions, a high-quality paper filter from a trusted brand is sufficient.

⚠️ Attention: Do not buy filters without packaging or of dubious origin. Counterfeits often have wrong sizes (for example, 200x180x30 mm instead of the original 205x185x32 mm), which leads to a loose fit and debris getting into the cabin.

Preparing for replacement: tools and work location

To replace the cabin filter with Murano Z51 No special skills are required, but a minimum set of tools is required:

• 🔧 Flat head screwdriver (for removing plastic clips).
• 🧲 Magnet or tweezers (so as not to lose the mounting screws).
• 🕯️ Flashlight (lighting under the glove compartment).
• 🧴 Antibacterial spray (optional, for processing air ducts).

It is better to do the work in a garage or on a level area. If you are replacing outdoors, choose a calm day to prevent dust and debris from getting into open air ducts. Also prepare vacuum cleaner with narrow nozzleto clear the installation area of accumulated dirt.

   • Gently press the latches with a flathead screwdriver and remove the cover.

3. Remove the old filter:

   • Pull the filter towards you and it should come out without effort.
   • If the filter fell apart, remove the residue with a vacuum cleaner.

Typical replacement mistakes and how to avoid them

Even experienced car owners sometimes make mistakes. Here are the most common:

• 🔄 Filter orientation is incorrect. If you mix up the top/bottom, the filtration efficiency will decrease by 30-40%. Always refer to the arrows on the body.
• 🧹 Ignoring air duct cleaning. Dust and debris accumulated behind the filter will negate the benefits of the new part. Use a vacuum cleaner or compressed air.
• 🔧 Assembly force. Do not press too hard on the glove compartment as this will cause the latches to break. It should snap into place with light pressure.
• 📏 Buying the wrong size filter. Even if visually it fits, gaps of 1-2 mm will lead to unfiltered air entering the cabin.

Another common problem is forget to check the drainage hole under the filter. It is located at the bottom of the housing and can become clogged with leaves or dirt. If the drainage is not working, moisture will accumulate in the filter, leading to mold. Clean the hole with wire or compressed air.

What should I do if there is still a smell after replacement?

If even after installing a new filter, an unpleasant odor remains in the cabin, the problem lies deeper. Here are possible causes and solutions:

• 🍄 Mold in air ducts. Treat the system with a special antibacterial spray (for example, Liqui Moly Klima-Anlagen-Reiniger). Spray it into the vents with the air conditioner on.
• 🚗 Dirty air conditioner evaporator. Professional cleaning with removal of the panel is required (it is better to contact the service).
• 🔥 Problems with the stove. If there is a burning smell, check the fuses and the heater motor (F27 in the fuse box).

If the smell appears immediately after replacing the filter, you may have installed poor quality carbon filter. Cheap analogues sometimes have an unpleasant chemical odor that disappears after 1–2 weeks. In this case, it is enough to ventilate the interior well.

How much does a replacement cost at the service center and when should I go there?

At an official dealership, replace the cabin filter with Murano Z51 will cost 1 500–2 500 ₽ (excluding filter cost). In independent services the price is lower - approx. 800–1 200 ₽. However, there are cases when it is better to trust the professionals:

• 🔧 If you glove box latches broken and you can't install it correctly.
• 🌡️ If after replacement The furnace or air conditioner stopped working (the sensor or wiring may have been damaged).
• 🦠 If in the salon strong musty smell, and self-processing did not help.

In other cases, replacing the filter is a simple operation that even a beginner can handle. The main thing is to take your time and follow the instructions.

FAQ: Frequently asked questions about replacing the cabin air filter on a Murano Z51

Is it possible to wash the cabin filter instead of replacing it?

Wash paper filters it's impossible - they delaminate and lose their shape. Carbon filters also cannot be restored. Only electrostatic filters (for example, from Knecht) can be washed with soapy water and dried with a hairdryer. However, their effectiveness after washing is reduced by 20–30%.

What happens if you drive without a cabin filter?

The absence of a filter will lead to:

• Fast contaminated air conditioner evaporator (will require expensive cleaning).
• Hit dust and insects into the cabin through the deflectors.
• Increased load on stove motor, which reduces its resource.

As a last resort, you can temporarily drive without a filter (for example, if it has broken down), but not longer than 1–2 weeks.

How often should the filter be changed if the machine is rarely used?

Even if the mileage is low, the filter ages over time. Maximum service life - 2 years, after which the material begins to deteriorate. If the car is parked in a garage, replacement once every 1.5–2 years is sufficient. If on the street - once a year.

Is the filter from Nissan X-Trail T31 suitable?

No, despite their external similarity, filters have different sizes. U X-Trail T31 the filter is narrower (195×180×30 mm), and it will not fit tightly into the seat Murano Z51. Using non-original sizes will result in unfiltered air entering the cabin.

Can HEPA filters be installed?

Theoretically yes, but in practice it is inappropriate. HEPA filters have a high density, which creates additional load on the stove fan. In addition, they require replacement every 5,000–8,000 km. For Murano Z51 A high-quality carbon or electrostatic filter is sufficient.
