Replacing the cabin filter on a Nissan Almera G15: detailed instructions with photos and tips

Cabin filter in Nissan Almera G15 - this is a small but critical element that directly affects the quality of air in the cabin, the operation of the ventilation system, and even the health of the driver and passengers. Over time, it becomes clogged with dust, pollen, soot and other contaminants, turning from a protective barrier into a breeding ground for bacteria and a source of unpleasant odors. If you notice that the interior has become stuffy, the air conditioner or heater is working less efficiently, and condensation appears on the windshield faster, it’s time for a replacement.

In car services they charge from 800 to 1500 rubles for this procedure, but in reality **replacing the cabin filter Almera G15** takes no more than 15 minutes and does not require special skills. In this article we will analyze the entire process from filter selection to final installation, point out common mistakes and give tips on how to extend the life of the new element. And if you doubt your abilities, don’t worry: after reading the instructions, even a beginner will cope with the task without problems.

When and why you need to change the cabin filter on Almera G15

The manufacturer recommends replacing every 15,000 km or once a year, but in practice this interval depends on operating conditions. For example, if you often drive on dusty roads, sit in traffic jams near industrial zones, or use a car in a metropolis with high levels of air pollution, the filter may become unusable after 8–10 thousand kilometers.

Here are the key 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 from the inside, especially in rainy weather.
• 👃 Unpleasant smell when the air blower is turned on (it often smells like mold or rot).
• 🌡️ Deterioration of climate control performance: the air conditioner does not cool well, the stove heats poorly.

Ignoring the problem leads not only to discomfort, but also to more serious consequences. A clogged filter increases the load on the fan, which can cause premature wear. In addition, dust and microparticles penetrate the lungs, causing allergies and respiratory diseases. And in advanced cases - when the filter turns into a “swamp” of moisture and dirt - there is a risk of mold developing in the ventilation system, which will be much more difficult to eliminate.

⚠️ Attention: If you notice that after turning on the airflow in the cabin, dampness or smell rotten, this is a signal that the filter is not just clogged, but the processes of decomposition of organic matter have begun in it. In this case, replace it as soon as possible and treat the ventilation system with an antibacterial spray (for example, Liqui Moly Klima-Anlagen-Reiniger).

Which cabin filter to choose for Nissan Almera G15

There are three types of filters on the market for Almera G15:

• 🔹 Paper (regular) - the most budget option (from 300 rubles), it traps only coarse dust and practically does not protect against allergens.
• 🔹 Coal - middle price segment (600–1200 rubles), effective against odors and toxic gases thanks to activated carbon.
• 🔹 HEPA filters - premium option (1500–2500 rubles), captures up to 99% of microparticles, including bacteria and viruses.

For most owners Almera G15 the optimal choice would be carbon filter. It provides a balance between price and quality of cleaning, especially relevant for urban conditions. If you have allergies or often travel with children, it is worth considering HEPA filter with antibacterial impregnation (for example, Mann Filter CU 29004 or Bosch 1 987 429 660).

Here is a table of compatible filters with article numbers and average prices:

Brand	Article	Type	Average price, ₽	Notes
Nissan	27277-BM40A	Original (paper)	800–1200	Suitable for warranty service
Mann Filter	CU 29004	Coal	900–1300	High quality, popular choice
Bosch	1 987 429 660	Coal	1000–1400	Good filtration, long service life
Filtron	K 1321 A	Coal	600–900	Budget analogue of the original
TSN	9.7.838	HEPA + carbon	1500–2000	Maximum cleaning, suitable for allergy sufferers

When purchasing, pay attention to filter sizes: for Almera G15 standard size - 200 × 200 × 25 mm. Some unscrupulous sellers may offer “universal” filters that do not fit in dimensions. Also check if the packaging is marked as compatible with Nissan Almera G15 (B0) or Renault Symbol (they use the same filters).

Preparing for replacement: tools and safety precautions

You don't need sophisticated equipment to replace the filter. Here's what you need to prepare:

• 🔧 New cabin filter (matching the article number).
• 🧹 Vacuum cleaner or compressor (to clean the housing).
• 🧴 Antibacterial spray (optional if there was a mold smell).
• 📸 Smartphone (to take a photo of the location of the old filter).
• 🧤 Gloves (protection from dust and dirt).

Before starting work, complete the following steps:

1. Park the car on a level surface and turn off the engine.
2. Open the hood and let the car cool down if it has been moving (this will prevent burns when working with plastic parts).
3. Turn off the ignition and remove the key - this will de-energize the fan so that it does not turn on accidentally.
4. If the filter is changed in rainy weather, cover the work area with an umbrella or awning - moisture should not enter the ventilation system.

⚠️ Attention: Never replace while the engine is running! The climate control fan may unexpectedly turn on even when the fan is turned off (for example, when automatically adjusting the temperature), which will lead to hand injuries or damage to the filter.

Also keep in mind that during the process of removing the old filter from the housing, a large amount of dust and debris may spill out. If you are allergic to dust, wear respirator or medical mask. After replacement, it is recommended to vacuum the mats and seats - some of the dirt will inevitably get into the interior.

Step-by-step instructions: how to replace the cabin filter on Almera G15

Now let's move on to the process itself. B Nissan Almera G15 The cabin filter is located behind the glove compartment, so access to it is quite convenient. Follow the instructions:

Step 1. Removing the glove compartment

1. Open the glove compartment and take all things out of it.
2. On both sides of the glove compartment, find plastic clips (they look like latches).
3. Carefully press the clamps inward and pull the glove compartment towards you - it should come out of the grooves.
4. Lower the glove compartment down to access the filter cover.

Step 2: Removing the filter cover

1. Under the glove compartment you will see black plastic cover with the inscription AIR FILTER or arrows.
2. Squeeze two latches on the sides of the lid and pull it towards you.
3. If the cover does not budge, do not use excessive force - check that all latches are pressed out.

Step 3: Removing the old filter

1. Behind the cover you will see the old filter. Grab its edge and pull down - it should come out without effort.
2. If the filter disintegrates or sticks, use a flathead screwdriver to carefully pry it out from the side.
3. After extraction inspect the body for leaves, insects or moisture. Vacuum it if necessary.

Step 4: Install a new filter

1. Check if it matches arrow direction on the new filter with the air direction (usually the arrow points ↓ DOWN or AIR FLOW).
2. Carefully insert the filter into the slots, making sure it is fits tightly around the entire perimeter.
3. Close the lid until it clicks and return the glove compartment to its place, securing the latches.

⚠️ Attention: If, when installing a new filter, you feel resistance or heard a plastic crack, stop pressing immediately! Most likely the filter is installed wrong (upside down or moved to the side). Forced installation may damage the housing or the filter itself, resulting in entry of unfiltered air into the cabin.

Typical replacement mistakes and how to avoid them

Even such a simple procedure as replacing the cabin filter is fraught with several pitfalls. Here are the most common mistakes and how to prevent them:

1. Wrong direction of the filter

The arrow on the filter indicates the direction of air flow. If you install it backwards, the cleaning efficiency will decrease by 30–40%, and the filter itself will clog faster. Always check the arrow or photo of the old filter!

2. Ignoring cleaning the case

Many people install a new filter in a dirty housing where leaves, dust and even mold remain. This reduces the filter service life by 2–3 times. Always clean the housing with a vacuum cleaner or damp cloth (if there are no electronics nearby).

3. Buying a non-original filter without checking the dimensions

“Universal” filters often do not fit in dimensions, leaving gaps through which untreated air passes. Check the article number and dimensions (for Almera G15 — 200 × 200 × 25 mm).

4. They forget about antibacterial treatment

If your old filter smells musty, simply replacing it is not enough. Spray the ventilation system (For example, Step Up SU-9011) through the deflectors, then ventilate the interior.

5. The lid or glove compartment is not tightly closed

If the filter cover or glove box is not fully secured, this may cause whistling sound when fan is running or dust entering bypassing the filter. Check all latches!

How to extend the life of your cabin filter

Even the highest quality filter will last longer if you follow a few simple rules:

1. Regular cleaning of the ventilation system

Once every 3 months, turn on the fan at maximum speed for 5-10 minutes to bleed the system from accumulated dust. It is also useful to treat the deflectors with an antibacterial spray every six months.

2. Control of humidity in the cabin

Mold and bacteria thrive in moist environments. To avoid this:

• 🚗 After rain or car wash dry the interiorby opening the windows for 10–15 minutes.
• 🌬️ Use air conditioner to reduce humidity (it dehumidifies the air).
• 🧊 In winter turn on the window defrost before your trip to remove condensation.

3. Parking in the shade

Direct sunlight heats the plastic of the glove compartment and filter housing, which can lead to deformation of seals and entry of unfiltered air. Try to park in the shade or use a sun screen.

4. Timely replacement

Don't wait until the filter starts to smell. Keep track of your mileage or set a reminder in your phone every 10–12 thousand km. Replacing the filter once a year (even with low mileage) will cost less than repairing the fan or treating allergies.

Frequently asked questions (FAQ)

Is it possible to drive without a cabin filter?

Technically yes, but it is highly undesirable. Without a filter, unpurified air containing dust, soot and allergens will enter the cabin. In addition, dust will settle on the air conditioner evaporator, which will lead to its premature wear and the appearance of an unpleasant odor. In the long run, this can result in expensive repairs to your climate control system.

How can you tell if the filter is installed incorrectly?

Signs of incorrect installation:

• Whistling or noise when the fan operates at high speeds.
• Poor air flow from the deflectors (even if the filter is new).
• Gaps between the filter and the housing (visible upon inspection).
• Foreign odors in the cabin (if the filter is installed backwards).

If you notice any of this, check the direction of the arrow on the filter and the tightness of the cap.

Is it possible to wash or clean the old filter instead of replacing it?

Paper and carbon filters cannot be cleaned — their structure is destroyed upon contact with water, and coal loses its adsorbing properties. The only option is to carefully vacuum the filter from the back side (without touching the surface), but this will give a temporary effect and will not eliminate bacteria. It's better not to save money and install a new one.

What is the difference between filters for Almera G15 and Almera Classic?

These are completely different models with different filter housings. For Almera G15 (B0, 2012–2019) fits filter with article number 27277-BM40A or its analogues. For Almera Classic (N16, 2006–2012) need a filter 27277-9M00A - it is smaller in size and has a different shape. They are not interchangeable!

Do I need to reset errors after replacing the filter?

B Nissan Almera G15 There is no cabin filter sensor, so no errors light up on the instrument panel. However, if you notice that the fan is unstable after replacement, check:

• Correct installation of the filter (are there any distortions).
• Fan fuse status (F37, 30A in the block under the hood).
• Keep the air intake clean (sometimes leaves or debris block the air flow).

If the problem persists, the fan itself or its resistor may be faulty.
