Minivan owners Nissan Serena The C27 generation often faces the need to maintain the interior ventilation system, especially given the harsh climatic operating conditions on the roads of Russia and the CIS countries. A dirty filter not only degrades air quality, but also puts serious stress on the heater motor, which can lead to premature failure. Regular replacing the cabin filter is a simple procedure that requires a minimum of time and tools, but brings tangible benefits to the health of passengers and the durability of the vehicle.
Many car owners mistakenly believe that to access the filter on the model Serena S27 it is necessary to disassemble half of the dashboard or remove the glove compartment, which discourages self-service. In fact, the design of this car was thought out by engineers to provide quick access to service items. In this article, we will look in detail at how to choose the right consumables, what tools you will need, and how to perform the replacement in a matter of minutes without contacting a service center.
Why do you need to replace the filter on Serena C27 and when to do it
Climate control system in a minivan Nissan Serena C27 works in intensive mode, pumping large volumes of air through the heater and air conditioner radiators. If cabin filter clogged with dust, lint and road grime, system efficiency decreases and air flow becomes weak and smells unpleasant. In such conditions, moisture does not have time to evaporate from the air conditioner evaporator, which creates an ideal environment for the growth of bacteria and mold.
The manufacturer recommends scheduled replacement of consumables every 15,000 kilometers or once a year, whichever comes first. However, if you operate the car in a city with high pollution or on dirt roads, the interval is reduced to 7,000–10,000 kilometers. Characteristic signs will indicate that it is time for replacement:
- 🌬️ Reducing the intensity of air flow from the deflectors even at maximum fan speed
- 🤢 The appearance of foreign odors (dampness, rot, exhaust gases) when the air blower is turned on
- 🦠 Increased fogging of windows in rainy weather due to poor circulation
- 🔊 The appearance of a whistle or noise from the electric motor of the stove when operating at high speeds
Ignoring these signals may result in you being forced to change not only the filter, but also more expensive components of the ventilation system. This is especially critical for owners of versions with climate control, where air quality sensors may give incorrect readings due to a clogged element.
⚠️ Attention: If you smell a burning smell while the stove is operating, stop immediately and check the filter. A severely clogged element can cause the fan motor to overheat and melt the plastic elements of the heater housing, which will require expensive repairs.
How to choose the right filter for Nissan Serena C27
There are a huge number of analogues on the auto parts market, but not all of them are suitable for the C27 body, since the dimensions of the filter element may differ from the previous generation. Original article for Nissan Serena C27 is 27277-3BA0A (coal) or 27277-3BA0B (paper). However, there are high-quality analogues that often surpass the original in filtration ability.
When choosing, you should pay attention to the type of filtration. Simple paper elements trap only coarse dust, while carbon filters additionally adsorb harmful gases and odors from the outside. For urban operating conditions of a minivan, it is definitely recommended to install carbon filter. Also pay attention to the presence of an antibacterial coating, which prevents the development of mold inside the filter itself.
Below is a table of popular models suitable for replacing the Serena C27, indicating their features and approximate cost:
| Brand and model | Filtration type | Features | Approximate price |
|---|---|---|---|
| Nissan (Original) | Coal | Perfect fit, proven quality | 2500–3500 ₽ |
| Victor Reinz 71-64000-00 | Coal | High cleaning efficiency, durable frame | 1200–1600 ₽ |
| Mahle LAK 208 | Coal | German brand, excellent filtration of fine dust | 1400–1800 ₽ |
| Sakura C-1520 | Paper/Carbon | Budget option, decent quality | 600–900 ₽ |
| Knecht/LA 260 | Paper | High air capacity | 800–1100 ₽ |
You should not save on your health by choosing the cheapest analogues of unknown brands. A cheap filter may have poor frame rigidity, causing it to deform and allow unfiltered air to bypass the filter material.
⚠️ Attention: When purchasing, pay attention to the direction of air flow indicated by the arrow on the filter frame. Incorrect installation can quickly clog the filter and reduce the efficiency of the air conditioner.

Preparing tools and work area
Replacement process Nissan Serena C27 does not require a specific set of tools or lifting the car onto an overpass. You only need access to the passenger side of the cabin and a minimum set of hand tools. If you plan to do the job yourself, make sure you have some free space to store the removed parts.
For comfortable work you may need:
- 🔧 Phillips screwdriver (cross PH2) - for unscrewing the screws securing the cover
- 🔦 Flashlight - to clearly see the internal cavity where the filter is installed
- 🧤 Gloves - to protect your hands from dust and dirt accumulated in the filter housing
- 🧽 Vacuum cleaner - for preliminary cleaning of the seat from debris
Before starting work, it is recommended to open the hood and disconnect the battery terminal, although this is not strictly necessary to replace the filter, since the electrical connectors in the heater block are not affected. However, if you plan to additionally clean the air conditioner evaporator, turning off the mass will be the right solution.
☑️ Preparation for replacement
Step-by-step instructions for replacing the filter
Access to the filter on the Serena C27 is through the glove box (glove compartment). The design allows access without completely removing the box itself, which greatly simplifies the task. Sit in the front passenger seat and open the door to provide easy access to the dashboard.
You need to open the glove box and inspect the right side (passenger side). There you will see plastic stops or screws holding the filter cover in place. On some modifications, you may need to lightly press the sides of the glove compartment so that it lowers below its normal position. If you have screws, carefully remove them with a Phillips screwdriver and place them in a safe place.
After removing the cover you will see the old filter. Pay attention to the direction of its installation: there is usually an arrow on the frame indicating the direction of air flow (Air Flow). Take a photo or remember the orientation of the old element so as not to confuse it when installing a new one. Pull the old filter out towards you in a smooth motion.
Before installing a new element, be sure to clear the cavity of dust, leaves and foreign debris. Use a vacuum cleaner or damp cloth to wipe down the sides of the case. Make sure that the rubber seals on the filter cover are not damaged and fit snugly into the housing when closing.
What to do if the filter doesn't fit?
If the new filter does not fit into the grooves, do not force it. Check that you have removed the cover correctly and that there is no excess debris in the way. Sometimes the frame may be slightly deformed during transportation - carefully straighten it by hand before installation.
Install the new filter, observing the direction of air flow. The arrow should point down or toward the engine (usually down on this model, but check the instructions on the package). Close the lid tightly and tighten the screws if they were removed. Make sure the cover is not loose or has any gaps.
The main mistake when replacing is installing the filter in the opposite direction. This dramatically reduces cleaning efficiency and can damage the fan.
Features of servicing systems with climate control
On versions Nissan Serena C27 with climate control, the filter replacement procedure has its own nuances. Air quality sensors located in the intake area may respond to dust remaining after the old filter is removed. After replacement, it is recommended to reset the adaptations or simply let the system operate at full power for 10–15 minutes.
If your car has a system superclimate with air ionization, make sure that the filter is marked accordingly. Some cheap analogues may block the operation of the ionizer due to the material structure being too dense or the lack of a special layer. Check the catalog for compatibility before purchasing.
It is also worth noting that the Serena C27 often has additional filters installed in the engine compartment area (suction), which also require attention. However, the main cabin filter is located behind the glove compartment. To completely clean the system, it is recommended to dry clean the evaporator every 2 years, especially if you notice a persistent damp smell.
After installing the new filter, turn on the air conditioner at maximum power for 5 minutes with the windows open. This will help ventilate the system and remove any remaining odors from the new filter material.
Common mistakes and expert advice
Many owners make the mistake of trying to wash and reuse the old filter. Even if visually it seems clean, the pores are clogged with microscopic dust, which cannot be removed without special equipment. Using a “saponified” filter negates all the benefits of the procedure. The filter is a consumable item, and it needs to be changed entirely.
Another common problem is damage to the plastic lid latches when removed. The plastic on Japanese cars is quite fragile, especially in winter. If the latch is broken, do not rush to replace the entire glove compartment. You can carefully glue it with plastic glue or use zip ties, the main thing is to ensure that the lid fits tightly.
When purchasing original spare parts, pay attention to the packaging. Counterfeits often have dull markings and lower quality rubber seals. If the price of the original seems suspiciously low, check the article number on the manufacturer’s website or in official catalogs. Never install a filter without a rubber frame, as this will lead to untreated air being sucked into the cabin.
