Cabin filter in Nissan Almera Classic (B10) is that invisible but critical element that is responsible for the cleanliness of the air in the cabin. Over time, it becomes clogged with dust, pollen, soot and even bacteria, turning from a protector into a source of unpleasant odors and allergens. If you notice that the ventilation is working worse, and when you turn on the heater, the cabin smells damp, it’s time to act.

In this article we will look at how to replace the cabin filter with Almera Classic with your own hands, without resorting to the help of a car service. The procedure takes no more than 20 minutes, and the savings will be from 800 to 1500 rubles (this is what the service station charges for this service). The main thing is to know where the filter is, what tool you will need and how to avoid common mistakes. We will describe each step in detail, show key points in the photo and give advice on choosing a new filter.

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

Unlike many modern cars, where the filter is hidden behind the glove compartment or under the hood, in Almera Classic (2006–2012) it is located in a not so obvious place - under the dashboard on the driver's side. More precisely, its housing is mounted in the air duct behind the center console, next to the pedal assembly.

To get to it, you don’t need to disassemble half of the interior - just remove the plastic trim under the steering wheel. However, many owners waste time by damaging the filter in the engine compartment or behind the glove compartment. On Almera Classic The cabin filter has never been installed in the engine compartment - this is a common misconception associated with confusion between different generations Almera.

  • 📍 Exact location: under the instrument panel, to the left of the clutch pedal (for manual transmission) or brake pedal (for automatic transmission).
  • 🔧 Access: you need to remove the plastic cover (2 clips) and bend the mat.
  • ⚠️ Caution: not to be confused with the air conditioning filter - it is not included in the basic configuration Almera Classic.

If this is your first time encountering this procedure, we recommend that you first clean the space under the driver’s feet - debris often accumulates there, which can get into the air ducts during replacement.

What tools and materials will be needed?

To replace the cabin filter with Nissan Almera Classic You don’t need a professional tool—what’s found in every home is enough. Here's the full list:

  • 🔨 Flat head screwdriver (or plastic spatula) - for removing the clips of the lining.
  • 🧹 Vacuum cleaner or brush - to clean the filter housing from dust before installing a new one.
  • 🔦 Flashlight — The lighting under the panel leaves much to be desired.
  • 🧤 Gloves (optional) - the filter may be dirty, and it will take a long time to wash your hands after work.
  • 📦 New cabin filter — more about this in the next section.

If the clips on the pad are too tight, you can use WD-40 or similar lubricant to gently loosen them. But usually they are removed without additional effort.

  • Every year
  • Once every 2 years
  • Only when the smell appears
  • Never changed

Which cabin filter to choose for Almera Classic?

On Nissan Almera Classic (B10) standard size filters are installed: 200×190×20 mm. They can be of two types:

  1. Regular (dusty) — retain only large particles (dust, soot, pollen). Cheap, but require replacement every 15–20 thousand km.
  2. Coal — additionally absorb harmful gases and unpleasant odors. They last longer (up to 25–30 thousand km), but cost 1.5–2 times more.

Among the trusted brands:

  • 🏆 Mann Filter (CU 20003) - optimal price/quality ratio.
  • 💰 Bosch (1 987 429 636) - a carbon filter with a high degree of purification.
  • 🔧 SCT (SA 2003) - a budget option for those who change the filter regularly.
  • 🚗 Nissan (27277-BM00A) - original, but often counterfeited.
Brand Article Type Average price (2026) Resource (thousand km)
Mann Filter CU 20003 Coal 600–800 ₽ 25–30
Bosch 1 987 429 636 Coal 700–900 ₽ 30
SCT SA 2003 Regular 250–400 ₽ 15–20
Nissan 27277-BM00A Original (carbon) 1200–1500 ₽ 30

If you live in a city with high levels of pollution or often sit in traffic jams, a carbon filter will be the best choice. For rural areas, an ordinary dust one is sufficient.

💡

Before purchasing, check the filter against the light: high-quality carbon filters have a uniform black layer without bald spots. Counterfeits are often gray or streaky.

Step-by-step instructions for replacing the cabin filter

Now let's move on to the process itself. Follow the instructions carefully to avoid damaging the clips or ducts.

  1. Preparation:

    Place the car on a level surface and set the parking brake. Move the driver's seat all the way back to make it easier to work.

  2. Removing the cover:

    Under the steering wheel, find the plastic trim (it covers the space under the panel). Carefully pry it with a screwdriver or spatula on the left side (door side) and pull it towards you. The clips should come out without effort. If the cover does not give way, do not pull by force - check that all the clips have snapped off.

  3. Filter access:

    After removing the cover you will see a black plastic filter housing with a cover. The cover is attached to two latches - press them to the sides and remove the cover.

  4. Removing the old filter:

    Remove the old filter by pulling it down. Be prepared for the fact that debris may fall out of it - it is better to lay it down with newspaper or a rag.

  5. Cleaning the case:

    Use a vacuum cleaner or brush to remove dust and dirt from the filter housing. If moisture has accumulated there (for example, due to condensation), wipe with a dry cloth.

  6. Installing a new filter:

    Insert the new filter with the arrow up (on most filters the arrow indicates the direction of air flow). Make sure it fits snugly with no gaps.

  7. Assembly:

    Close the housing cover, replace the plastic cover (the clips should click into place with a characteristic sound).

If after replacing you feel that the air from the ventilation is blowing weaker than before, check whether the filter is installed correctly - it may be blocking the air flow.

What to do if the pad clips are broken?

If the plastic clips crack during removal, they can be replaced with universal ones (item no. 90467-01216 for Nissan). Clips from Renault or Lada similar size. As a last resort, the overlay can be secured with double-sided tape, but this is a temporary solution.

Common mistakes and how to avoid them

Even such a simple procedure as replacing the cabin filter may not go according to plan if the nuances are not taken into account. Here are the most common mistakes and how to prevent them:

⚠️ Attention: Never install the filter "in reverse" (arrow down). Not only will this reduce the cleaning efficiency, but it can also allow debris to get into the ducts, causing noise when the fan operates.
  • 🔄 The side of the filter was mixed up. Most filters have an arrow indicating the direction of air flow. If it is not there, install the filter so that the corrugations are vertical.
  • 🧹 The body was not cleaned. If you leave old dust in the housing, it will quickly clog the new filter. Use a vacuum cleaner or compressed air.
  • 🔧 The lining clips were broken. Do not pull the cover by force - first release all the clips. If the clips are still broken, replace them (see spoiler above).
  • 💨 Forgot to check the seal. Some filters have a foam seal along the edge - it must fit tightly to the body, otherwise air will bypass the filter.

Another common problem is loose fit of the housing cover. If it does not snap fully into place, a gap remains between the cover and the body, through which unfiltered air enters the cabin. Check the cover for cracks or deformations.

When to change the cabin filter: signs and frequency

The manufacturer recommends replacing the cabin filter with Nissan Almera Classic every 15,000 km or once a year. However, in real conditions this interval is often reduced. Here are signs that it's time to replace the filter:

  • 🌬️ Weak air flow from the deflectors when the ventilation is on.
  • 👃 Unpleasant smell (dampness, mold) when turning on the stove or air conditioner.
  • 🤧 Increased allergic reactions in passengers (sneezing, itchy nose).
  • 🌫️ Visible dust from the air ducts when the blower is turned on.
  • 🔊 Extraneous noise (whistle, crackling) when the fan operates at high speeds.

If you often drive on dusty roads, get stuck in traffic jams or live in a metropolis, the filter may become clogged after 8–10 thousand km. In this case, it is better to focus not on the mileage, but on the condition of the filter. To check, just remove it and shine it with a flashlight - if the light does not pass through, the filter must be replaced.

It is also worth remembering that carbon filters lose their adsorbing properties through 6–12 months, even if the mileage is short. Therefore, it is recommended to change them once a year, regardless of mileage.

💡

If in your Almera Classic Windows often fog up; this may be a sign not only of a faulty filter, but also of a clogged air conditioner drain. In this case, additional cleaning of the system will be required.

What happens if you don't change the cabin filter?

Many owners Nissan Almera Classic They neglect replacing the cabin filter, considering it a “minor” part. However, the consequences of this approach can be serious:

  1. Deterioration of health.

    A clogged filter becomes a breeding ground for bacteria, mold and fungi. When the ventilation is turned on, spores enter the lungs of the driver and passengers, causing allergies, asthma and chronic cough.

  2. Damage to the ventilation system.

    Dust and debris penetrating through the destroyed filter settle on the heater radiator and air conditioner evaporator. This leads to their corrosion and expensive repairs.

  3. Reduced heater efficiency.

    A clogged filter restricts air flow, causing the furnace to heat less efficiently and the air conditioner to work less efficiently. In winter, this can lead to frosted glass.

  4. Unpleasant odors.

    The humid environment in a clogged filter promotes the proliferation of microbes, which is why a persistent damp smell appears in the cabin, which cannot be eliminated with air fresheners.

According to statistics, the cost of repairing a stove or air conditioner due to a clogged ventilation system can reach 15–20 thousand rubles, while replacing the filter costs 300–1500 rubles. It is more profitable to spend 20 minutes on prevention than to pay later to eliminate the consequences.

FAQ: Frequently asked questions about replacing the cabin filter on Almera Classic

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

Technically yes, but this is a temporary solution. Washing with water will only remove surface dust, but will not restore the adsorbent properties of the carbon layer (if any) or eliminate microbes. In addition, a wet filter can become deformed or become a source of mold. Better to spend money on a new one.

Which filter is better - carbon or regular?

A carbon filter is more effective at trapping harmful gases (for example, exhaust from traffic jams) and neutralizing odors, but is more expensive. A regular filter is cheaper, but does a worse job of removing fine dust and allergens. The choice depends on the operating conditions: for the city, coal is better, for rural areas - regular.

What should you do if, after replacing the filter, the air in the cabin becomes weaker?

The filter is probably installed incorrectly (for example, with the arrow pointing down) or the housing cover is not fully latched. Also check for debris in the air ducts. If the problem remains, the heater radiator may be clogged or the fan is faulty.

Can I install a filter from another Nissan model?

No, filters from Nissan Qashqai, X-Trail or Note will not fit - they have different sizes and shapes. Use only filters designed for Almera Classic (B10) or its twin - Renault Samsung SM3 (they are identical).

Do I need to reset errors after replacing the filter?

No, in Almera Classic There is no cabin filter sensor, so no errors light up. If after replacement an icon appears on the panel (for example, CHECK), this is a coincidence - look for the problem elsewhere.
