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

B Nissan Almera Classic (body B10 And N16) the cabin filter is located behind the glove compartment on the passenger side. This is a typical place for most Japanese cars, but there are nuances:

• 🔧 On models until 2006 The filter may not be present from the factory - there is a plug instead. In this case, you will have to purchase additional fasteners.
• 📏 Dimensions of the original filter: 200 × 190 × 20 mm (for coal - thickness up to 25 mm).
• 🚗 On restyled versions (after 2008), access to the filter is a little more difficult due to the modified glove compartment design.

To get to the filter, you do not need to disassemble the dashboard or remove the lining. Enough:

1. Open the glove compartment and remove all contents from it.
2. Press the latches on the sides of the glove compartment (they are located closer to the passenger compartment).
3. Lower the glove compartment down - it will hang on the lower mounts.

Which cabin filter to choose: original or analogue?

Original filter from Nissan has an article number 27277-BM400 (regular) or 27277-1M025 (coal). Its average price is 1,200–1,800 rubles. However, many owners prefer analogues that are cheaper but not inferior in quality.

Brand	Article	Type	Price, ₽	Features
Nissan	27277-BM400	Regular	1 200–1 500	Original, guaranteed compatibility
Mann	CU 22003	Coal	800–1 100	High quality, good filtration
Bosch	1 987 429 655	Regular	600–900	Budget option, suitable for dusty regions
Filtron	K 1152	Coal	700–1 000	Good price/quality ratio
Sakura	CAF22003	Regular	400–600	The cheapest analogue, but the filtration quality is lower

When choosing, consider:

• 🌿 Carbon filters They cope better with odors, but clog up faster (recommended replacement interval is 15 thousand km).
• 🏜️ In regions with high dust levels (for example, near quarries), conventional filters will have to be changed more often - every 10 thousand km.
• ⚠️ Cheap analogues (< 500 ₽) may have poor fit or low quality filter material.

Step-by-step instructions for replacing the cabin filter

Before starting work, prepare:

• 🔧 New filter (check compatibility by article number).
• 🧹 Vacuum cleaner or brush to clean the case.
• 📸 Phone for photo recording (in case something goes wrong).
• 🔦 Flashlight (the lighting in the glove compartment niche is usually weak).

Now let's start replacing:

1. Removing the glove compartment:

   Press the plastic clips on the sides of the glove compartment (they are located closer to the passenger compartment) and lower it down. If the glove compartment does not budge, check whether it rests against the fuse box (on some versions Almera Classic it is located on the right).

2. Filter access:

   Behind the glove compartment you will see a plastic lid with latches. Carefully remove it by pulling it towards you. In some cases, the cover can be screwed on with self-tapping screws (usually Torx T20).

3. Removing the old filter:

   Remove the old filter by pulling it down. Be prepared for the possibility of debris falling out of there - it is better to lay down a newspaper or use a vacuum cleaner.

   What to do if the filter is stuck?

   If the filter cannot be removed, check to see if it is bent due to moisture. Gently pry it up from the side with a flathead screwdriver, but do not use too much force to avoid breaking the fasteners.

4. Cleaning the case:

   Before installing a new filter, clear the niche of dust and leaves. Use a vacuum cleaner or damp cloth. Do not use compressed air - this may drive dust deeper into the ventilation system.

5. Installing a new filter:

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

6. Assembly:

   Replace the cover, latch it, and return the glove compartment to its original position. Check that all fasteners are in place.

Typical replacement mistakes and how to avoid them

Even such a simple procedure as replacing the cabin filter can turn into problems if mistakes are made. Here are the most common ones:

⚠️ Attention: If, after replacing the filter, a whistle or noise appears in the cabin when the stove is operating, most likely the filter is installed crookedly or on the wrong side. This may damage the heater fan.

• 🔄 Filter orientation is incorrect. The arrow on the filter indicates the direction of air flow. If you place it upside down, the filtration efficiency will drop by 30–40%.
• 🧹 Ignoring case cleaning. If you do not remove debris from the niche, the new filter will clog 2-3 times faster.
• 🔧 Damage to the glove box latches. Many owners break the plastic latches when trying to remove the glove compartment by force. If the latch does not budge, check for hidden fasteners.
• 💨 Using incompatible filters. Filters from Nissan Note or Micra Look similar, but may not be the right size. Always check the article number.

Another common problem is forget to check the drainage hole. It is located under the filter and serves to drain condensate. If it is clogged, there will be dampness in the cabin, and constant fogging on the windows. Clean it with wire or compressed air (but carefully!).

When to change the cabin filter: signs and frequency

The manufacturer recommends changing the cabin filter every 20–25 thousand km or once a year. However, in real conditions this interval is often reduced. Here are the key signs that it's time to replace the filter:

• 🌫️ Weak airflow from the stove/air conditioner even at maximum speed.
• 👃 Foreign odors in the cabin (mold, dampness, exhaust gases).
• 💨 Dust on the dashboard even after cleaning, it penetrates through a clogged filter.
• 🌡️ Poor cooling or heating of the interior — the filter interferes with normal air circulation.

In some cases, the filter requires replacement ahead of schedule:

Operating conditions	Recommended replacement interval
Driving on dirt roads, construction zones	Every 10–15 thousand km
Frequent parking under trees (foliage, fluff)	Every 15 thousand km
High humidity, frequent rain	Every 15–20 thousand km (risk of mold)
Driving in a metropolis with high levels of smog	Every 15 thousand km (charcoal filter)

If you buy Nissan Almera Classic with mileage, Replacing the cabin filter should be your first priority. - the previous owner may never have done this. Check its condition: if the filter is deformed or wet, this is a sign that moisture has accumulated in the ventilation system.

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

Many owners ignore replacing the cabin filter, considering it a “minor” part. However, the consequences can be serious:

⚠️ Attention: A clogged filter increases the load on the stove fan, which can lead to its failure. The cost of a new fan is from 5,000 rubles, plus replacement work.

• 🦠 Proliferation of bacteria and mold. A wet filter becomes an ideal environment for fungus, which then enters the lungs of the driver and passengers.
• 🚗 Reduced visibility. Due to weak airflow, the windows take longer to fog up, which is dangerous in rainy weather.
• 💰 Increased fuel consumption. When the filter is clogged, the climate control system works in enhanced mode, which increases the load on the engine.
• 🔥 Risk of fire. In extreme cases, accumulated debris can be ignited by a spark (for example, a short circuit in the wiring).

On owner forums Almera Classic There are often stories about how a dirty filter broke down interior temperature sensor or heater damper jammed. Repair in such cases costs 3–5 times more than timely replacement of the filter.

FAQ: Frequently asked questions about replacing the cabin filter

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 is a temporary solution. After washing:

• Filtration efficiency drops by 40–60%.
• The carbon layer (if any) loses its properties.
• A wet filter can become a source of mold.

It’s better to spend 500–1,000 rubles on a new filter than to risk your health.

Which filter is better - carbon or regular?

The choice depends on the operating conditions:

• Coal better suited for cities with poor ecology (collects exhaust gases and odors).
• Regular cheaper and lasts longer in clean regions.

If you often sit in traffic jams, a carbon filter is worth it, despite the higher price.

Do I need to lubricate the seals when installing the filter?

No, no lubrication is required. However, if the seals on the filter cover are cracked, they can be treated silicone grease (For example, WD-40 Specialist). This will prevent squeaks and improve sealing.

What should I do if, after replacing the filter, the stove blows weaker?

Possible reasons:

1. The filter is installed on the wrong side (check the arrow).
2. Debris has accumulated in the ventilation system (the air ducts need to be cleaned).
3. The heater fan is faulty (diagnostics required).

First, check that the filter is installed correctly. If the problem persists, contact service.

Is it possible to drive without a cabin filter?

Technically yes, but it is fraught:

• Dust and dirt will fall directly into the interior and onto the heater radiator.
• The wear of the fan and dampers will increase.
• The cabin will constantly smell of exhaust fumes (if you drive in traffic jams).

If the filter is missing from the factory (as on some Almera Classic until 2006), it is better to purchase and install it.
