Cabin filter for Nissan Almera G15 with air conditioning: complete guide

Cabin filter in Nissan Almera G15 with air conditioning is not just a consumable, but a key element that affects the comfort and health of the driver. In city traffic jams and dusty roads, it delays up to 95% harmful particles, preventing them from entering the lungs. But when it comes to a model with climate control, increased demands are placed on the filter: it must not only purify the air, but also protect the air conditioner evaporator from contamination, otherwise the risk of an unpleasant odor and system breakdown increases significantly.

Owners Almera G15 Often faced with a dilemma: which filter to choose - carbon or regular? How often should it be changed if the car is operated in a metropolis or rural area? And why after replacement may a whistle appear or the efficiency of the air conditioner decrease? In this article we will look at all the nuances: from article numbers of original and analog filters to step-by-step replacement instructions, taking into account design features Almera G15. We will also reveal the myths about “eternal” filters and explain why saving on this consumable is more expensive than repairing the ventilation system.

Why does the cabin filter in the Almera G15 with air conditioning require special attention?

Air conditioning in Nissan Almera G15 It works on the principle of a closed cycle: the air passes through the evaporator, where it is cooled, and then supplied to the cabin. If the cabin filter is clogged, air flow is reduced and the system becomes overloaded. This leads to:

• 🔥 Compressor overheating - the most expensive air conditioner unit, the repair of which costs 20–30 thousand rubles.
• 🦠 Reproduction of bacteria on a wet evaporator - a source of persistent mold odor.
• ❄️ Evaporator freezing — due to insufficient air exchange, moisture condenses and freezes, blocking the flow of cold air.

In addition, in Almera G15 the filter is located in an inconvenient place - under the glove compartment, but with access through the glove box. This makes replacement more difficult, but avoids disassembling the panel. Important: if you hear a whistle or the air flow weakens when you turn on the air conditioner, this is a direct signal that the filter is critically dirty. In such cases, replacement is required immediately, otherwise the risk of system failure increases by 40%.

Original and similar filters: articles and comparison

Original cabin filter for Nissan Almera G15 (2012–2018) has an article number 27277-JK00A (regular) and 27277-JK00B (coal). However, their price in dealership centers is often overpriced - from 1,200 to 1,800 rubles. An alternative is proven analogues:

Brand	Article	Type	Price, ₽	Features
Mann Filter	CU 22011	Coal	850–1 100	High dust holding capacity, 3 layers of activated carbon
Bosch	1 987 429 660	Regular	600–800	Optimal for urban use
Filtron	K 1152 A	Coal	700–950	Good protection against allergens, but clogs faster
SCT	SA 2011	Regular	400–600	Budget option, suitable for rare use

When choosing between a carbon and a regular filter, be guided by operating conditions:

• 🏙️ City traffic jams - carbon filter (Mann CU 22011 or Filtron K 1152 A), as it neutralizes exhaust gases and odors.
• 🌳 Country routes - regular filter (Bosch 1 987 429 660), since there is less dust, and coal loses its properties faster.
• 🚜 Dusty roads - only coal with high dust capacity, for example, Mann, but you will have to change it every 7–8 thousand km.

⚠️ Attention: Filters from Nissan Note (article 27277-4M000) are similar in appearance, but not suitable for Almera G15 — they are 15 mm shorter, which is why they do not fit tightly to the body, allowing unfiltered air to pass through.

Step-by-step instructions for replacing the filter in Almera G15

Replacing the cabin filter in Nissan Almera G15 does not require special tools, but there are nuances associated with the design of the glove compartment. You will need:

• 🔧 Flat screwdriver (for glove compartment clamps).
• 🧴 Air conditioner cleaner (optional if there is an odor).
• 📏 Flashlight - the lighting under the glove compartment is weak.

Sequence of actions:

1. Open the glove compartment and remove all things from it. Press on the side walls of the glove compartment to release the latches (they are located closer to the interior).
2. Lower the glove compartment down — it will hang on the lower mounts. Do not pull too hard to avoid breaking the plastic latches!
3. Remove the filter cover — it is attached to two plastic clips. Use a screwdriver to pry it off on the right side.
4. Remove the old filter. Pay attention to the direction of the arrow on the frame - the new filter should be installed in the same way.
5. Clean the case remove dust and debris with a vacuum cleaner or damp cloth. If there is mold, treat with an antibacterial spray (such as Liqui Moly Klima-Anlagen-Reiniger).
6. Install a new filter, observing the direction of air flow (indicated by the arrow on the frame).
7. Reassemble everything in reverse order. Make sure the glove box fits into place without distortion.

If after replacement there is a whistling sound when the air conditioner is operating, check:

• 🔄 Correct installation of the filter - A skewed frame can block air flow.
• 🕳️ Seal integrity on the filter cover - if it is damaged, unfiltered air will leak.
• 🌬️ Clogged air ducts — sometimes leaves or debris get into the ventilation system.

⚠️ Attention: If you hear plastic cracking when removing the glove compartment, do not panic. B Almera G15 The fasteners often break when first removed. They can be replaced with similar ones from Nissan Micra K13 (article 80510-4M000).

Common replacement errors and their consequences

Even experienced car owners make mistakes when replacing the cabin filter in Almera G15. Here are the most common:

1. Ignoring the direction of air flow. If the filter is installed backwards, its efficiency drops by 60%, and dust penetrates into the evaporator faster. There is always an arrow on the filter frame with the inscription AIR FLOW - she should watch down (towards the floor).
2. Using non-original filters without checking the sizes. For example, filters from Renault Logan similar in appearance, but 5 mm narrower, which causes gaps to form. This leads to the entry of unfiltered air and accelerated wear of the air conditioner.
3. Replacing the filter without cleaning the housing. If there is dust or leaves left in the housing, they will immediately clog the new filter. In advanced cases this leads to overgrowing of the air conditioner drain pipe, which causes water to flow into the cabin (usually under the passenger’s feet).

Another typical problem is an attempt to “extend the life” of the filter by washing or purging it. This is useless for two reasons:

• 🧹 Mechanical particles (dust, soot) penetrate deep into the filter fibers and are not washed out.
• ☠️ Activated carbon after getting wet, it loses its adsorption properties and becomes a breeding ground for bacteria.

1. Turn on the air conditioner to maximum airflow.

2. Spray the product into the air intake (located under the windshield).

3. Close the windows and wait 10 minutes.

This will remove up to 90% of bacteria and fungi.-->

How often to change the filter: recommendations and real experience

Official regulations Nissan requires replacing the cabin filter every 15,000 km or once a year. However, these figures are relevant for “ideal” conditions - clean European roads and a temperate climate. In the realities of Russia and the CIS, the deadlines are reduced:

Operating conditions	Recommended replacement interval	Signs that replacement is needed
Megapolis (Moscow, St. Petersburg)	8–10 thousand km	Smell of dust when turning on the fan, low air flow
Industrial cities (Chelyabinsk, Novokuznetsk)	6–8 thousand km	Black deposits on the deflectors, whistling when the air conditioner is running
Rural areas (dirt roads)	5–7 thousand km	Visible dust on the dashboard, fogged windows
Southern regions (Krasnodar, Rostov)	10–12 thousand km	Smells mold, air conditioner blows weaker

To accurately determine whether it is time to change the filter, perform a simple test:

1. Turn on the interior fan at maximum speed.
2. Hold a piece of paper near the deflector. If he not held air flow - the filter is clogged.
3. Smell the air from the ducts. The smell of dampness or dust is a sign of bacterial growth.

Interesting fact: in Almera G15 with mileage of more than 100 thousand km is often observed filter housing deformation due to vibrations. This leads to unfiltered air being sucked in even with a new filter. The solution is to install a sealing tape around the perimeter of the lid (for example, self-adhesive foam rubber 3 mm thick).

What happens if you never change the filter?

After 30–40 thousand km without replacement, the filter turns into a “dust bag”, which:

1. Completely blocks the air flow - the air conditioner only blows at speed 1-2.

2. Becomes a source of mold - spores spread throughout the cabin, causing allergies.

3. Increases the load on the fan - its motor burns out 3 times more often (replacement cost - from 5 thousand rubles).

4. The air conditioner drain clogs - water begins to flow onto the floor, which leads to corrosion of the body under the passenger mat.

Myths and truth about cabin filters for Almera G15

There are many myths surrounding cabin filters, especially when it comes to models with air conditioning. Let's look at the most popular:

Myth 1: “You don’t have to change the carbon filter for 2 years—it cleans itself.”

Truth: Activated carbon is not regenerated. After 6–8 months, the pores of the coal become clogged and stop absorbing odors. Moreover, saturated coal begins to highlight previously absorbed substances are returned to the cabin.

Myth 2: “If the air conditioner is working properly, the filter does not need to be changed.”

Truth: The air conditioner may blow cold air even with a clogged filter, but at the same time:

• 🔋 Fuel consumption increases (by 3–5%) due to increased load on the generator.
• 🦠 The concentration of CO₂ and harmful microorganisms increases in the salon.

Myth 3: "Filters from other Nissans (such as Juke or Qashqai) are suitable for the Almera G15."

Truth: Even if the filters are similar in appearance, they may differ in:

• 📏 Thickness - filter from Qashqai 3 mm thicker, which is why it does not fit into the grooves.
• 🔄 Flow direction - in Almera G15 air flows from top to bottom, and in Juke - from bottom to top.

Myth 4: "After changing the filter, the air conditioner starts blowing louder."

Truth: This is only possible if the old filter was 80%+ clogged. In other cases there will be no difference, but air quality will improve significantly - the dust on the dashboard and the smell when the fan is turned on will disappear.

What to do if problems arise after replacing the filter

Sometimes after replacing the cabin filter in Almera G15 unexpected problems arise. Let's look at the most common ones and their solutions:

Problem 1: The air conditioner blows weaker than before the replacement.

Causes and solutions:

• 🔄 The filter is installed backwards - turn it over according to the arrow AIR FLOW.
• 🕳️ The filter cover is not closed tightly — check the clamps, if necessary, bend them with pliers.
• 🌪️ Air ducts are clogged — professional cleaning is required (cost: from 2 thousand rubles).

Problem 2: There was a whistling noise when the fan was running.

Causes and solutions:

• 🎵 Filter is not the right size - even a difference of 2-3 mm can cause turbulence. Return the old filter and compare dimensions.
• 🧊 Evaporator freezing - if the whistle appears only in cold air, it means that the moisture does not have time to evaporate. You need to check the drainage tube (it should be free).

Problem 3: There was a smell in the cabin after replacing the filter.

Causes and solutions:

• 🦠 Mold on the evaporator - treatment with an antibacterial composition is required (for example, Wynn's Airco Cleaner).
• 🚗 New filter smell - some cheap filters (especially Chinese ones) have a chemical smell. It will disappear after 1-2 days of airing.

If none of the solutions worked, check:

• 🔌 Fan motor operation - When worn, it may make a whistling sound. Diagnostics: Turn on the fan at different speeds. If the whistle increases with increasing speed, there is a problem in the motor.
• 🔧 Duct integrity - in Almera G15 Sometimes dampers (rubber gaskets) fall off, causing extraneous noise.

FAQ: Answers to frequently asked questions

Is it possible to drive without a cabin filter?

Technically yes, but this will lead to:

• Rapid clogging of the air conditioner evaporator (repair - from 10 thousand rubles).
• Dust and soot getting into the lungs is especially dangerous for allergy sufferers.
• Accelerated wear of the fan (replacement - from 4 thousand rubles).

B Almera G15 Without a filter, dust settles on the air quality sensor (located next to the filter), which leads to false alarms of the climate control.

Which filter is better - carbon or regular?

The choice depends on the conditions:

• Coal — if you drive in the city, you often sit in traffic jams or smoke inside. It traps up to 90% of harmful gases (NO₂, SO₂) and neutralizes odors.
• Regular — if you operate the car outside the city or on clean roads. It is cheaper and does not require frequent replacement.

Important: the carbon filter loses its properties after 6–8 months, even if the mileage is short. After that, it works like a regular one, but costs more.

Why did the air conditioner start to blow worse after replacing the filter?

Probable reasons:

1. The filter is installed on the wrong side (arrow AIR FLOW should look down).
2. The filter cover is not closed tightly - check the latches.
3. Clogged air ducts require professional cleaning.
4. The fan motor is faulty (worn brushes or bearings).

B Almera G15 There is also a defect in the filter housing - cracks through which air leaks. Inspect the housing for damage.

Is it possible to wash the cabin filter?

No, it's useless and dangerous:

• Water destroys the structure of the filter, reducing its efficiency by 70%.
• Once wet, carbon filters become a breeding ground for bacteria.
• It is almost impossible to dry the filter without deformation.

Exception - blowing with compressed air (for example, at a service station), but this is a temporary measure. The filter will not survive complete cleaning.

How to check whether the filter is original or not?

Signs of the original filter Nissan:

• There is a hologram with the logo on the packaging Nissan.
• The filter is packed in thick polyethylene with a branded sticker.
• The frame is engraved with an article number (27277-JK00A/B) and logo.
• The carbon filter has a uniform black color without gaps.

Counterfeits are often 1–2 mm thinner, have uneven edges and a faint smell of glue. When installed, they may not fit tightly to the body.
