Cabin filter in Nissan Almera G15 - this is a small but critical detail on which not only the cleanliness of the air in the cabin depends, but also the serviceability of the ventilation system, air conditioning and even the heater. Over time, the filter becomes clogged with dust, pollen, soot and microparticles, which leads to poor air flow, unpleasant odors and increased fan load. In this article we will look at how to change the cabin filter yourself Almera G15 (including restyled versions 2016–2022) without contacting the service.
The replacement procedure takes no more than 15–20 minutes and does not require special skills or tools. However there are several key nuances, which are worth considering: from choosing the right filter (regular or carbon) to carefully dismantling the plastic latches so as not to break them. We will also tell you how to determine when it is time to change the filter, and what consequences await you if you ignore this procedure.
When to change the cabin filter on a Nissan Almera G15: signs and timing
The manufacturer recommends replacing the cabin filter every 15,000 km or once a year, but in practice this interval may vary depending on operating conditions. If you often drive on dusty roads, sit in traffic jams near industrial areas or suffer from allergies, the filter may become clogged after 8-10 thousand km.
The following signs indicate that it is time for replacement:
- 🌬️ Weak air flow from the deflectors even at maximum fan speed.
- 🤧 Constant smell of dampness or mold when you turn on the air conditioner or heater.
- 🚗 Fogging of windows for no apparent reason (especially in rainy weather).
- 💨 Dust on the dashboard, which appears literally a day after cleaning.
If you ignore these symptoms, the consequences may be more serious than you think. A clogged filter increases the load on the fan, which leads to premature wear. In addition, harmful bacteria and fungi accumulate in the cabin, which can cause allergic reactions or respiratory diseases.
⚠️ Attention: On Nissan Almera G15 with air conditioning, a dirty filter can cause evaporator icing. This is manifested by weak blowing of cold air even with a working compressor. In such cases, replacing the filter often solves the problem without additional repairs.
- Every 10,000 km
- Once a year
- Only when problems arise
- Never changed
Which cabin filter to choose for Nissan Almera G15: original vs analogues
On Almera G15 Two types of cabin filters are installed:
- 🔹 Regular (dusty) - trap large particles of dust, soot and pollen. Suitable for regions with clean air.
- 🔹 Coal — additionally absorb harmful gases (for example, exhaust) and unpleasant odors. Optimal for megacities.
Original filter from Nissan has an article number 27277-BM40A (regular) or 27277-4M025 (coal). However, its price is often inflated, and high-quality analogues are cheaper. The table below shows the tested options:
| Brand | Article | Type | Notes |
|---|---|---|---|
| Nissan (original) | 27277-BM40A |
Regular | Guaranteed compatibility, but high price (~1,200–1,500 RUR). |
| Mann | CU 29003 |
Coal | One of the best price/quality ratios (~800–1,000 RUR). |
| Bosch | 1 987 429 655 |
Regular | Good filtration, but a little harsher than the original (~600–800 RUR). |
| Filtron | K 1321 |
Coal | Budget option (~500–700 RUR), but the carbon layer is thinner. |
When choosing, pay attention to filter sizes: he must be 200 × 200 × 20 mm. Some cheap analogues may have inaccurate dimensions, which makes them difficult to install in the seat. Also check if the filter has air direction arrows - this is important for correct installation.
If you live in an area with high humidity, choose a carbon filter with antibacterial impregnation (for example, Mann CU 29003). This will prevent mold from growing in the ventilation system.
Tools and preparation for replacing the cabin filter on Almera G15
You don't need a complicated tool to change the filter. You will need:
- 🔧 Flat-head screwdriver (or plastic pick for removing latches).
- 🧹 Vacuum cleaner or brush for cleaning the seat.
- 📦 New cabin filter (check the article number before purchasing!).
- 🔦 Flashlight (optional, for a better view).
Before starting work, follow a few simple steps:
- Park the car on a level surface and turn off the ignition.
- Open the glove compartment and get all the things out of it - this will make it easier to access the filter.
- If the air conditioner has been running recently, wait 5-10 minutes for the evaporator to dry (this will prevent moisture from getting on the new filter).
⚠️ Attention: Do not replace the filter immediately after washing the car or in rainy weather. Moisture entering the ventilation system can lead to mold formation on a new filter within 1–2 weeks.
☑️ Preparing to replace the filter
Step-by-step instructions: how to replace the cabin filter on a Nissan Almera G15
Filter in Almera G15 located behind the glove compartment, so access to it does not require disassembling the panel. Follow this instruction:
Step 1. Removing the glove compartment
Click on two latches on the sides of the glove compartment (they are located inside, closer to the cabin) and pull it towards you. The glove compartment should go down, but cannot be completely removed - it is held in place by the limiter cable.
Step 2: Removing the filter cover
Behind the glove compartment you will see a black plastic cover with two latches on the sides. Gently pry them out with a flathead screwdriver or your fingers and remove the cover.
Step 3: Removing the old filter
The old filter is located vertically. Pull it down by the bottom edge and it should come out without any effort. If the filter is stuck, do not yank it sharply: check for additional latches.
Step 4: Clean the seat
Before installing a new filter be sure to vacuum or wipe the seat with a damp cloth. Dirt accumulated there can immediately clog the new filter.
Step 5: Install a new filter
Please note arrows on the filter - they must be directed down (in the direction of air movement). Insert the filter into the grooves and press lightly until it fits tightly.
Step 6: Reassemble in reverse order
Install the filter cover, snap it into place, then return the glove compartment to its place (it should click into place).
What to do if the filter does not fit into place?
If the new filter does not fit into the grooves, check:
1. Correct direction (arrows should point down).
2. Are there any extra protrusions or defects on the filter?
3. Cleanliness of the seat (sometimes there are pieces of the old filter left there).
If the problem persists, try bending the edges of the filter slightly (but do not break them!).
Common mistakes when replacing the cabin filter and how to avoid them
Even something as simple as replacing a filter can go wrong if you don’t take a few things into account:
Error 1: Incorrect filter direction
If you install the filter upside down, not only will it not perform its function, but it may also accelerate fan wear due to increased air resistance. Always follow the arrows or the inscription AIR FLOW.
Mistake 2. Ignoring footprint cleaning
Many people install a new filter in a dirty housing, which leads to its rapid clogging. Dust and debris in the seat can reduce filter life by 30–40%.
Mistake 3: Using incompatible filters
Some owners buy filters from other models Nissan (for example, from Note or Tiida), since they are similar in appearance. However, even a slight discrepancy in size can lead to poor sealing and the entry of unfiltered air into the cabin.
Mistake 4. Forgetting to check the seal
The original filters have a rubber seal around the perimeter that prevents air from penetrating bypassing the filter. Cheap analogues may not have it - in this case, it is recommended to additionally seal the edges of the filter with foam tape.
If after replacing the filter there is still an unpleasant odor in the cabin, the cause may be a dirty air conditioner evaporator. In this case, treatment with a special cleaner (for example, Liqui Moly Klima-Anlagen-Reiniger).
How to extend the life of the cabin filter on a Nissan Almera G15
The average filter life is 1 year, but with proper care it can be increased by 20–30%. Here are some tips:
- 🚿 Clean the ventilation system regularly. Once every 3 months, turn on the air conditioner at maximum power with the windows open for 5-10 minutes - this will help blow out accumulated dust.
- 🌿 Use antibacterial fragrances. They slow down the growth of microbes in the filter (e.g. Sonax Climate Control Spray).
- 🚗 Park in the shade. Direct sunlight accelerates the destruction of the carbon layer in the filter.
- 🔄 Dry the filter periodically. If moisture gets in (for example, after rain), turn on the blower at maximum temperature without air conditioning for 15 minutes.
If you often drive on dusty roads, you can install prefilter (mesh at the air intake inlet). It traps large particles and extends the life of the main filter. However, please note that the pre-filter requires cleaning every 1-2 months.
What will happen if you do not change the cabin filter on Almera G15: consequences
Many owners put off replacing the filter, not realizing what problems this can lead to. Here are the most common consequences:
| Problem | Reason | Repair cost |
|---|---|---|
| Weak airflow from deflectors | A clogged filter creates resistance, causing the fan to wear out. | From RUB 3,000 (fan replacement) |
| Unpleasant smell in the cabin | Bacteria and fungi multiply in the filter. | From 1,500 ₽ (system cleaning) |
| Fogging of windows | Air circulation is impaired and humidity is increased. | From 500 ₽ (filter replacement + evaporator cleaning) |
| Air conditioner breakdown | A dirty filter causes icing of the evaporator. | From 10,000 ₽ (air conditioner repair) |
On a Nissan Almera G15 with automatic climate control, a dirty filter can cause sensor failure, which will lead to the system not working properly (for example, the heater will blow cold air). In this case, the control unit will need to be reflashed, which will cost 5,000–7,000 rubles.
Another hidden risk - increased CO₂ concentration in the cabin. When the filter is clogged, air circulates in a vicious circle, which leads to driver drowsiness and poor reaction. This is especially dangerous on long trips.
FAQ: Frequently asked questions about replacing the cabin filter on a Nissan Almera G15
Is it possible to wash the cabin filter instead of replacing it?
Technically, you can wash the filter (for example, with a vacuum cleaner or a weak stream of water), but this will not restore its properties. After washing, the carbon layer loses its adsorbing properties, and the paper filter is deformed. Such “savings” can lead to dirt getting into the ventilation system. It is better to buy a new filter - its price is not commensurate with the potential consequences.
Which filter is better: original or analogue?
The original filter is guaranteed to be suitable in size and quality, but there is often no point in overpaying for it. Analogues from Mann, Bosch or Filtron no worse, and sometimes even superior to the original in filtering properties. The main thing is to buy from trusted sellers so as not to run into a fake.
Do I need to reset errors after replacing the filter?
On Nissan Almera G15 There is no cabin air filter sensor, so no errors light up on the dashboard. However, if you noticed code P0400 (malfunction of the air recirculation system), after replacing the filter, it should be reset using a scanner or by disconnecting the battery terminal for 10 minutes.
Is it possible to replace the filter without removing the glove compartment?
Theoretically, you can try to remove the filter without removing the glove compartment completely, but this is extremely inconvenient. The risk of breaking the latches or tearing the filter with this approach is very high. It is better to spend an extra 2 minutes dismantling the glove compartment than to repair it later.
What to do if a whistle appears after replacing the filter?
Whistling usually occurs due to loose filter fit or a foreign object gets into the air duct. Check:
- Is the filter installed correctly (arrows down).
- Are there any gaps between the filter and the housing?
- Are there any pieces of the old filter left in the seat?
If the whistle does not disappear, inspect the fan blades - they may be touching the housing.
