Replacing the cabin filter on a Nissan Almera Classic: instructions with photos and videos

Cabin filter in Nissan Almera Classic - this is a small but critical detail on which the air quality in the cabin, the operation of the ventilation system and even the life of the air conditioning system depend. Many owners forget about its existenceuntil they begin to notice a persistent smell of mold, weak airflow from the stove, or constant fogging of the glass. Meanwhile, you can replace the cabin filter on this model in 10–15 minutes without special tools - just know the location of the hatch and a few nuances.

In this article you will find step-by-step instructions with photos and videos, article numbers of original and alternative filters, as well as answers to frequently asked questions: how often to change, what signs indicate clogging, and what will happen if you ignore replacement. We will also look into unique feature Almera Classic — lack of a standard hatch under the glove compartment for some modifications, due to which the process may differ from what is usual for other cars Nissan.

Where is the cabin filter located in the Nissan Almera Classic?

In most versions Nissan Almera Classic (including restyled models B10 And G15) the cabin filter is located behind the glove compartment on the passenger side. However, there is an important nuance here: depending on the year of manufacture and configuration, it can be accessed:

• 🔧 Through the hatch under the glove compartment - a classic option, as on most cars.
• 🚗 By removing the glove compartment — in some modifications (for example, early versions for the Russian market) there is no hatch, and the filter is hidden deeper.
• ⚠️ Absent at all — on basic configurations before 2010, the filter may not have been installed from the factory (required to be completed).

To determine exactly which version your car has, just look under the glove compartment: if there is a plastic cover about 15×20 cm with latches - you're in luck. If not, you will have to remove the glove compartment (instructions below). The photo below shows a typical hatch (marked in red):

💡 Hint: If you are not sure whether your car has a filter, check the VIN number in the catalog Nissan or look for the presence of a plastic air duct housing behind the glove compartment - even if there is no hatch, there may be a plug there.

Signs of a clogged cabin filter

The manufacturer recommends changing the cabin filter every 15–20 thousand km or once a year, but in practice the period depends on operating conditions. For example, in large cities with high dust levels or with frequent trips on dirt roads, the filter may become unusable after only 8–10 thousand km. The following symptoms indicate that it is time to replace it:

• 🌬️ Weak air flow from the deflectors even at maximum fan speed.
• 🤧 Constant fogging of windows, especially in rainy weather - a clogged filter interferes with air circulation.
• 🦠 Unpleasant smell (mold, dampness) when you turn on the stove or air conditioner - a sign of bacterial growth in a dirty filter.
• 🚫 Allergic reactions for passengers, pollen, dust and microparticles penetrate into the cabin.
• 🔊 Extraneous noise (whistle, hum) when the fan is running - the filter creates resistance to the air flow.

⚠️ Attention: If you ignore these signs, the consequences may be more serious than you think. A clogged filter increases the load on stove fan, which leads to its premature wear. In addition, condensation can accumulate in the air conditioning system, creating an ideal environment for fungus and bacteria - this is fraught not only with odor, but also with health problems (especially for asthmatics).

Which filters are suitable for Nissan Almera Classic: original vs analogues

For Nissan Almera Classic Two types of filters are suitable: ordinary dust (only large particles are retained) and coal (additionally absorb odors and harmful gases). Original articles and popular analogues are shown in the table below:

Filter type	Original article	Analogs (brand + article)	Notes
Dust (standard)	27277-BM00A	Mann CU 22003 Bosch 1 987 429 636 Filtron K 1152	Suitable for most versions, including restyling
Coal	27277-4M025	Mann CUK 22003 Bosch 1 987 429 642 SCT SAK 319	Better at retaining odors, but more expensive and requires more frequent replacement
Dust (for versions without hatch)	27277-95F0A	Mahle LA 923 FRAM CF10134	Used if the filter is being installed for the first time (modification of the housing is required)

🔍 How to choose? If you drive mostly in a city with high traffic, a carbon filter will be justified - it copes better with exhaust gases and odors. For rural areas or rare trips, an ordinary dust one is sufficient. Please note dimensions: standard filter for Almera Classic has dimensions of approximately 190×185×20 mm, but some analogues may have minor deviations (up to ±2 mm).

⚠️ Attention: When purchasing, check availability sealing frame along the perimeter of the filter. Cheap analogues often do not have it, which is why gaps remain between the filter and the housing - this negates the effectiveness of air purification.

Step-by-step instructions for replacing the cabin filter

The replacement process depends on whether your car has hatch under the glove compartment. Below are instructions for both cases.

Option 1: Replacement through the hatch (the easiest way)

If there is a plastic cover under the glove compartment, you will only need flat blade screwdriver (or knife) and a new filter. Procedure:

1. Open the glove compartment and remove all items from it.

2. Click on glove compartment latches on the sides and lower it down (it is not completely removable, but only folds back).

3. Under the glove compartment you will see a plastic hatch with two latches. Carefully pry it up with a screwdriver and remove it.

4. Pull out the old filter by pulling it towards you. Be careful - it may contain a lot of dust and debris.

5. Clean the planting area from leaves and dirt (you can vacuum it).

6. Install a new filter down arrow (on most models the arrow indicates the direction of air flow).

7. Close the hatch and return the glove compartment to its place.

Option 2: Replacement without hatch (requires removal of glove compartment)

If there is no hatch, the process becomes more complicated, but remains doable without visiting a service center. You will need:

• Screwdriver Torx T20 or cross;
• Flat screwdriver for removing clips;
• Flashlight (for illuminating the seat).

Instructions:

1. Open the glove compartment and remove two screws Torx T20 at the top (they can be hidden by plugs).

2. Remove the glove compartment side trims by prying them off with a flat-head screwdriver (be careful not to break the clips!).

3. Disconnect the glove compartment from the panel, first disconnecting the backlight connector (if equipped).

4. Behind the glove compartment you will see a black plastic air duct housing. The filter is inside - pull it towards you.

5. Install the new filter, following the direction of the arrow, and reassemble everything in reverse order.

📌 Important: When reassembling, make sure that all glove compartment clips are in place. If at least one remains unassembled, the glove compartment will dangle or squeak.

What to do if the filter does not fit into the seat?

If the new filter is slightly wider than the original, you can carefully trim it along the edges with a knife (no more than 2–3 mm). The main thing is not to touch the carbon layer (if there is one). Also check if you have mixed up the top and bottom: sometimes the filter does not fit due to the wrong orientation.

Common replacement mistakes and how to avoid them

Even such a simple procedure as replacing the cabin filter can be ruined. Here are the most common ones and how to prevent them:

• ❌ Installing the filter upside down - if the direction of the arrow is reversed, the cleaning efficiency will decrease by 30–40%. Always check the labeling!
• ❌ Ignoring cleaning the seat — Accumulated leaves and debris can clog the drainage hole, leading to water buildup and mold.
• ❌ Buying a filter without a seal — unfiltered air will pass through the cracks, negating all the benefits of the replacement.
• ❌ Strong compression of the filter during installation — carbon filters cannot be bent, otherwise the sorbent will lose its properties.
• ❌ Forgetting to check the drainage — under the filter there is a small hole for condensate drainage. If it is clogged, the interior will be damp.

⚠️ Attention: If after replacing the filter in the cabin there is whistling sound when the stove is runningMost likely, the filter is installed crookedly or is not fully seated in the grooves. Do not ignore this sound - it indicates increased load on the fan, which can lead to its failure.

🔧 Advice from the experts: After replacing the filter, turn on the stove at maximum power and check the strength of the air flow from all deflectors. If the airflow is weak, perhaps the problem is not in the filter, but in clogged air duct or a faulty fan.

How to extend the life of your cabin filter

Although the filter is a consumable, its resource can be increased if you follow a few simple rules:

• 🚿 Clean the drain hole regularly under the filter (once every 3–4 months). To do this, just blow it with compressed air or rinse with water.
• 🌿 Use antibacterial fragrances — they slow down the proliferation of microbes in the ventilation system.
• 🚗 Park in a garage or under a carport - this reduces the entry of dust and moisture into the air ducts.
• 🔄 Periodically turn on the air conditioner for 10–15 minutes even in winter - this dries out the system and prevents mold.
• 🛑 Avoid driving through puddles at high speed — splashes of water can enter the air intake and wet the filter.

💡 Useful lifehack: If you often drive on dusty roads, you can install non-woven pre-filter (sold in hardware stores). It is attached in front of the main filter - it traps large dust, prolonging the life of the main element. This prefilter needs to be changed every 3–5 thousand km.

FAQ: Answers to frequently asked questions

Is it possible to drive without a cabin filter?

Technically yes, but this is fraught with consequences: unfiltered air with dust, pollen and exhaust gases will enter the cabin. Additionally, without a filter, debris and leaves can clog the air ducts and furnace fan, causing it to break down. If there is no filter from the factory, it is better to complete the machine - the cost of the filter (300–800 ₽) is not comparable to the health risks and repair of the ventilation system.

Which filter is better: carbon or regular?

A carbon filter is more effective at removing odors and harmful gases (for example, from exhaust), but it is more expensive and clogs faster. A regular dust one is cheaper and lasts longer, but does not cope with odors. The choice depends on the operating conditions:

• For a city with traffic jams - coal;
• For out-of-town trips - normal;
• For allergy sufferers - only charcoal with antibacterial impregnation.

What happens if you don't change the filter for years?

The consequences range from discomfort to serious damage:

• Deterioration of the microclimate in the cabin (odor, dust);
• Increased load on the stove fan (the motor may burn out);
• Clogged air conditioner evaporator (you will have to disassemble the dashboard for cleaning);
• Mold in air ducts (antibacterial treatment required).

In advanced cases, the cost of repairs may exceed 20–30 thousand ₽.

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

Dust filters cannot be cleaned - their fibers become clogged with microparticles that cannot be removed. Carbon filters can theoretically be washed with water and dried, but this is a temporary measure: the sorbent loses its properties after getting wet. If your budget is limited, it is better to buy a new regular filter (from 300 ₽) than trying to “reanimate” the old one.

Where is the cabin filter air intake located?

B Nissan Almera Classic the air intake is located at the base of the windshield on the passenger side (under the plastic grille). This is where dust, leaves and moisture get in, so it is important to keep this area clean. If the grille is clogged, filtration efficiency decreases, even if the filter is new.
