Car interior ventilation system Nissan Almera Classic plays a critical role for the comfort of the driver and passengers. A dirty air intake or clogged cleaning element can lead to foggy windows, unpleasant odors and even headaches for passengers during long trips. Many owners are faced with the problem of finding the correct spare part code, since catalogs often contain different designations for the same part.
Correctly selected original article ensures that the filter will fit perfectly in the seat and will not allow dust to pass through the gaps. Ignoring replacement dates or installing cheap, low-quality analogues can lead to a decrease in the efficiency of the air conditioner and an increase in the load on the heater fan. In this article we will analyze all the nuances of choice, find the exact spare part codes and describe the process of self-replacement.
Why is it important to change the filter on your Nissan Almera Classic on time?
The cabin filter is the first barrier to external pollution. In a metropolis, where the air is saturated with exhaust gases and dust, this consumable becomes clogged much faster than the factory scheduled replacement suggests. If you operate the car mainly in the city, then the replacement interval should be reduced from the recommended 15-20 thousand kilometers to 10-12 thousand.
A clogged element creates high aerodynamic resistance to air flow. This leads to the heater fan starting to work at its limit, creating a characteristic whistle or noise. Besides, throughput decreases air conditioning systems, and cold air simply stops flowing into the cabin in the required volume. In the cold season, this also affects the rate at which the glass warms up, as the airflow becomes weak.
Particular attention should be paid to the health of passengers. An old filter becomes a breeding ground for bacteria and fungi, especially if moisture accumulates in it. When ventilation is turned on, these spores enter directly into the lungs. Using quality carbon filter helps not only to retain dust, but also to neutralize unpleasant odors from the exhaust gases of other cars.
⚠️ Attention: If you smell damp or musty when you turn on the stove, this is a sure sign that it is time to change the filter immediately, otherwise mold may penetrate into the air conditioner evaporator.
Original catalog number and its decoding
The main question that worries owners Nissan Almera Classic — what specific article to look for in the store. For this model (B10 body), the manufacturer has provided several options for original parts. The most common code is 27277-AN00A. This is a standard paper filter that is installed from the factory on most machines.
However, there is a more advanced version with activated carbon. Her article looks like this: 27277-AN00C. The difference in the letter index at the end of the code indicates the type of filler. The letter “A” stands for a regular paper element, and the letter “C” (from the English Carbon) stands for carbon. A carbon filter is more expensive, but it is more effective at cleaning the air from harmful impurities and odors.
When ordering a spare part, it is important to indicate the vehicle’s VIN code, since in different years of production there may have been minor changes in the design of the filter housing or seats. Sometimes you can find code in catalogs 27277-AN010, which is interchangeable with the main article, but is most often found in the CIS spare parts markets. Make sure that you are buying the part for the B10 body and not for the new Almera (B11), as they have different dimensions.
⚠️ Attention: When buying a filter without packaging, be sure to check the dimensions. A fake may differ from the original by 2-3 millimeters, which will lead to distortion and the entry of unfiltered air into the cabin.
The best analogues: what spare parts manufacturers offer
It doesn't always make sense to overpay for a box with a logo. Nissan. There are many proven brands on the market that produce filters that are superior in quality to the original. The key factor when choosing an analogue is the density of the filter material and the presence of a carbon layer.
Here is a list of the most reliable alternatives with their SKUs that are great for Nissan Almera Classic:
- 🔹 Mann-Filter - model
CU 20004orCU 20005(coal). German quality, perfect geometry. - 🔹 Mahle - article number
LAK 568. One of the best options in terms of price and quality of filtration. - 🔹 Victor Reinz - code
82-20016-00. Often delivered to conveyors, very reliable. - 🔹 Patron - article number
PFC8006. A budget option, but requires careful checking for defects when purchasing. - 🔹 Champion - model
CUF 1042. It traps coarse dust well, but may be inferior in filtering odors.
When choosing an analogue, pay attention to the “Carbon” or “Coal” markings on the packaging. If protection from exhaust odor is important to you, a regular paper filter from the list above will not work, even if it costs less. The carbon layer significantly increases the cost of the part, but this is justified by the comfort in traffic jams.

Where is the filtration element located in a car?
Unlike many modern foreign cars, where the filter is hidden under the dashboard and requires removal of the console, in Nissan Almera Classic access to it is simplified as much as possible. The element is located in the engine compartment, in a special plastic case located at the base of the windshield on the passenger side.
You don't need any special tools to gain access. You just need to open the hood and find a rectangular black plastic box. It is closed with a lid, which is attached to several plastic fasteners (clips). This design allows the ventilation system to be serviced in a matter of minutes, making regular replacement possible even for beginners.
It is important to understand that in this place the filter is exposed to external factors: moisture, dirt and leaves. That is why the housing cover is often covered with a layer of dirt, which must be removed before opening, so that debris does not get inside the ventilation system during replacement.
Step-by-step instructions for replacing the cabin filter
The replacement process does not take much time, but requires care so as not to break the plastic clips. Start by opening the hood and making sure the engine is off and cool. Locate the plastic box at the base of the windshield.
Next, follow the algorithm of actions:
- 🛠️ Inspect the housing cover and find the plastic latches. There are usually three or four of them. Gently pry them out with a screwdriver or your fingers.
- 🛠️ Remove the body cover and set it aside, being careful not to scratch the hood paint.
- 🛠️ Remove the old filter. Pay attention to the direction of the airflow arrows to install the new element correctly.
- 🛠️ Insert the new filter all the way, making sure it fits snugly against the edges of the housing.
- 🛠️ Close the lid and snap the latches until you hear a characteristic “click” sound.
☑️ Preparation for replacement
Pay special attention to the direction of the air flow. There is always an arrow on the filter frame indicating where the air should go. Usually the arrow should point down or towards the cabin (depending on the design of the housing), but it is best to use the old filter as a guide if it is not deformed.
What to do if the filter cannot be pulled out?
If the filter gets stuck, do not pull it forcefully. It's most likely stuck due to moisture or dirt. Gently rock it from side to side to break the vacuum clutch and try again.
After installing a new element, check the operation of the system. Turn on the fan at maximum speed and listen to the sounds. If the whistle disappears and the air flow becomes noticeably stronger, it means the job was completed successfully.
Proper installation of the filter in the direction of air flow is critical to the efficient operation of the HVAC system.
Comparative characteristics of filter types
The choice between a regular and a carbon filter is always a compromise between price and functionality. A regular paper filter does an excellent job of trapping large dust, fluff and insects. It is the cheapest solution and is suitable for those who rarely drive in city traffic jams.
The carbon filter contains a layer of activated carbon that acts as an adsorbent. It traps molecules of gases, ozone and unpleasant odors. However, the carbon layer slightly reduces the air passage area, which may slightly reduce the fan's performance compared to its paper counterpart.
Below is a table comparing the main characteristics of popular types of filters for Nissan Almera Classic:
| Filter type | Article (example) | Dust filtration | Odor protection | Cost |
|---|---|---|---|---|
| Paper (Original) | 27277-AN00A |
High | Missing | Low |
| Coal (Original) | 27277-AN00C |
High | Excellent | Average |
| Multilayer (Mann) | CU 20005 |
Very high | good | Average |
| Budget analogue | PFC8006 |
Average | Missing | Very low |
Common mistakes when choosing and installing
One of the most common mistakes is purchasing the wrong size filter. Sometimes sellers may make a mistake or offer a part from a newer model Nissan Almera, which will not physically fit into the case. If the filter is too small, it will simply fall inside the housing or leak air around the sides.
Another mistake is ignoring the direction of flow. If you install the filter backwards, its efficiency will drop significantly, and dust will clog the fibers faster. The airflow arrow should always coincide with the direction of air movement in the system.
You should also not try to wash and reuse the paper filter. The structure of the paper is destroyed by moisture, and after drying it loses its filtering properties. This may cause dust to enter directly into the interior.
Sometimes owners forget to clean the body of leaves and dirt before installing a new element. As a result, even a new filter quickly becomes clogged with small debris that remains at the bottom of the housing. This reduces the service life of the new part.
Cleaning the filter housing of old dirt and leaves before installing a new part will prolong its service life and prevent mold.
