Cabin filter in Nissan Note E12 - This is a small but critical element that directly affects the quality of air in the cabin, the operation of the air conditioning system and even the health of the driver and passengers. Many owners Nissan Note the first generation (2006–2013) underestimate its role until they encounter foggy windows, unpleasant odors or allergic reactions. In this article we will look at how to choose the right filter, when to change it, and why saving on this component can result in expensive repairs.
Structurally Note E12 equipped with a standard paper or carbon filter (depending on the configuration), which is installed in a special compartment under the glove compartment. However, access to it is not as obvious as in newer models Nissan, and incorrect replacement can lead to damage to the plastic latches or a loose fit of the filter. We will tell you in detail about the nuances of the procedure, provide article numbers of original and analog filters, and also explain why some “universal” solutions may not be suitable.
Why do you need a cabin filter? Nissan Note E12 and what will happen if you don’t change it
The main function of the cabin filter is to clean the air entering the cabin through the ventilation system from dust, pollen, soot, bacteria and harmful gases. In urban environments, where the concentration of harmful particles is 5-10 times higher than normal, the filter becomes a barrier between your lungs and smog. However, over time it becomes clogged and its effectiveness drops to 20–30% of its original value. This is what happens if you ignore the replacement:
- 🚗 Deterioration of the microclimate: Dust accumulates in the cabin, a damp smell appears, and when the heater or air conditioner is turned on, particles of debris fall directly into the driver’s face.
- 🌫️ Fogging of windows: A clogged filter reduces air flow, causing moisture to condense on the windshield and side windows, impairing visibility.
- 🦠 Reproduction of bacteria: The moist environment inside the filter becomes an ideal environment for mold and mildew, which can cause allergies and respiratory diseases.
- 🔧 Increased fan load: The stove motor is overloaded, which leads to its premature wear (the characteristic “whistle” when the air blower is turned on is the first sign).
The problem is especially relevant for Nissan Note E12 with air conditioning: if the filter is not changed, the air conditioner evaporator begins to freeze, and the drain pipe becomes clogged with dirt. This leads to antifreeze leaks into the cabin and the appearance of a puddle under the passenger’s feet. Owners Note E12 Models from 2008–2010 often encounter this problem due to the design features of the ventilation system, where the filter is located closer to the evaporator.
⚠️ Attention: If, after turning on the air conditioner, a rotten smell appears in the cabin, this is a sure sign that the filter is not only clogged, but also covered with mold. In this case, it will be necessary not only to replace the filter, but also to treat the evaporator with special antiseptics (for example, Liqui Moly Klima-Anlagen-Reiniger).
Signs that the cabin filter Nissan Note E12 it's time to change
The manufacturer recommends replacement every 15,000 km or once a year, but in the realities of Russian roads and climate this interval is often reduced to 10,000 km. Here are the key symptoms that indicate the need for replacement:
| Sign | Reason | What to do |
|---|---|---|
| Weak air flow from the deflectors when the ventilation is on | The filter is clogged with dust and does not allow air to pass through | Urgent filter replacement + fan check |
| The windows fog up even when the air blower is on | Air circulation is impaired due to a clogged filter | Replacing the filter + checking the recirculation valve |
| Unpleasant odor (dampness, mold) when turning on the stove or air conditioner | Moisture accumulates on the filter and bacteria multiply | Filter replacement + system disinfection Climate Control |
| Increased fan noise at high speeds | The fan is overloaded due to low filter throughput | Filter replacement + fan bearing diagnostics |
If you notice any of these signs, don't delay replacement. In advanced cases, you will have to clean not only the filter, but also the entire air duct system, and this is a time-consuming and expensive procedure. For example, in services for cleaning the evaporator of an air conditioner with Nissan Note E12 they charge from 3,000 to 5,000 rubles.
- Every 10,000 km
- Once a year
- Only when problems arise
- Never changed
Choosing a cabin filter for Nissan Note E12: original vs analogues
There are more than 50 variants of cabin filters on the market for Note E12, but not all of them are equally effective. Original filter from Nissan has an article number 27277-4M000 (paper) or 27277-4M001 (coal). Its average price is 1,200–1,500 rubles. However, many owners prefer analogues, which are often not inferior in quality, but are cheaper.
When choosing, pay attention to:
- 📏 Dimensions: The filter must fit perfectly into the seat. For Note E12 standard dimensions -
200 × 190 × 25 mm. - 🔬 Filter type:
- Paper (plain): It traps only large particles (dust, pollen), but does not cope with gases and odors. Suitable for regions with clean air.
- Coal: additionally absorbs harmful gases (for example, exhaust) and unpleasant odors. Optimal for the city.
- Electrostatic: has a special coating that attracts small particles (including bacteria). Expensive but effective option.
- 🏭 Manufacturer: give preference to brands with a good reputation: Mann-Filter, Bosch, Framm, Sakura, TSN.
The table below compares popular analogues of the original filter:
| Brand | Article | Type | Price (RUB) | Features |
|---|---|---|---|---|
| Mann-Filter | CU 22011 | Coal | 800–1 000 | High quality carbon layer, tight fit |
| Bosch | 1 987 429 655 | Coal | 900–1 100 | Good filtration of fine particles, long service life |
| Framm | CF 10104 | Paper | 400–600 | Budget option, suitable for temporary replacement |
| Sakura | CAF22011 | Coal | 700–900 | Japanese quality, reliable protection against allergens |
| TSN | 9.7.582 | Electrostatic | 1 200–1 400 | Retains up to 99% of bacteria, recommended for allergy sufferers |
If you live in a metropolis or often drive on dusty roads, it is better to immediately take a carbon filter. It is more expensive, but pays for itself by protecting your health and extending the life of your air conditioner. But cheap “no-name” filters (price up to 300 rubles) often have a poor seal, which is why unpurified air leaks into the cabin through the cracks.
Before purchasing, check whether the filter has a rubber seal around the perimeter. Without it, the filter will not fit tightly to the housing, and dust will flow around its edges.
Step-by-step instructions for replacing the cabin filter with Nissan Note E12
Replacing the filter with Note E12 does not require special tools and takes no more than 15 minutes. However, there are several nuances that should be taken into account in order not to break the plastic latches. Here are the detailed instructions:
☑️ What you will need to replace
Step 1. Preparation
Park the car on a level surface and turn off the engine. Open the glove compartment and remove all items from it. Then press on the sides of the glove compartment to release the latches and lower it down. In some trim levels Note E12 The glove compartment is attached to two plastic latches - they need to be carefully snapped off with a screwdriver.
Step 2: Access the filter
Behind the glove compartment you will see a plastic filter cover (black or gray). It is attached with two clips. To remove it, press the latches on the sides and pull the cover towards you. Be careful - the clips are fragile and can easily break if you pull too hard.
Step 3: Removing the old filter
The old filter is pulled out downward. It can be very dirty, so it is better to wear gloves. Pay attention to the direction of the arrows on the filter - they indicate the correct installation position (air flow should go from top to bottom).
Step 4: Install a new filter
Before installing a new filter, clean the seat from dust and debris with a damp cloth. Insert the filter with the arrows pointing upward (on some models there are no arrows - then follow the inscription UP or AIR FLOW). Make sure it fits snugly with no gaps.
Step 5. Assembly
Close the filter cover by snapping the clips into place and return the glove compartment to its place. Check that it is fixed without play. After replacing, turn on the fan at maximum speed and check if there is any extraneous noise (this may indicate a loose filter).
What to do if the glove box latches are broken?
If the plastic glove box latches are cracked, they can be temporarily replaced with small screws (3x10 mm) or plastic ties. For a complete repair, you will need to replace the clips (part number 80510-4M000 for Note E12).
⚠️ Attention: On some versions Nissan Note E12 (for example, with climate control), the filter may be installed a little deeper, and to remove it you will need to squeeze the side walls of the housing. Do not use excessive force - if the filter does not fit, check for additional fasteners.
Common mistakes when replacing the cabin filter with Nissan Note E12
Even something as simple as replacing a filter can be done incorrectly, leading to problems. Here are the most common mistakes and their consequences:
- 🔄 Incorrect filter orientation: if you install it upside down, the filtration efficiency will drop by 40-50%. The arrows on the filter should point down (in the direction of the air flow).
- 🧹 Ignoring footprint cleaning: If you do not remove accumulated dirt before installing a new filter, it will immediately enter the cabin when the fan is turned on.
- 🔧 Using a used filter: some owners try to “extend the life” of the filter by soaking it in fragrances or rinsing it with water. This is useless - after getting wet, the paper filter is deformed, and the carbon filter loses its absorbent properties.
- 🚫 Buying a filter that is the wrong size: Even if the filter is similar in appearance, but does not fit in size, it will not fit tightly, and dust will bypass.
Another typical problem is they forget to check air conditioner drain pipe. It is located under the filter and often becomes clogged with leaves and debris. If the tube is clogged, condensation from the air conditioner will accumulate in the cabin, which will lead to dampness and an unpleasant odor. To clean it, just blow the tube with compressed air or rinse with water.
After replacing the filter, be sure to turn on the air conditioner for 5–10 minutes at maximum airflow. This will help to “blow out” the system and remove any remaining dust.
How to extend the life of the cabin filter in Nissan Note E12
Although the filter is a consumable, its resource can be increased by 20–30% if you follow a few simple rules:
- 🌿 Ventilate the interior regularly: After driving, open the doors for 5–10 minutes to allow the moisture to evaporate. This will prevent mold from forming on the filter.
- 🚿 Use an ozonizer or antibacterial spray: Once every 3 months, treat the ventilation system with products such as Step Up Airco Clean or Sonax Klima-Fresh. This kills bacteria and eliminates odors.
- 🌡️ Monitor the operation of the air conditioner: If it starts to cool worse or condensation appears, check the filter and drain tube.
- 🛣️ Avoid driving on dusty roads with the windows open: this reduces the filter service life by 2–3 times. If you have to drive off-road, turn on the recirculation for 5 minutes after the trip to clean the air in the cabin.
It is also useful to check the condition of the filter visually every six months. To do this, you don’t need to remove it - just shine a flashlight through the glove compartment grille. If the filter looks gray or black, it's time to change it, even if the mileage has not reached the recommended 15,000 km.
FAQ: Frequently asked questions about the cabin filter Nissan Note E12
Is it possible to drive without a cabin filter?
Technically yes, but it is highly discouraged. Without a filter, unpurified air containing dust, soot and bacteria will enter the cabin. In addition, debris will accumulate on the air conditioner evaporator, which will lead to its failure. In the long term, this will result in repairs costing 10,000–20,000 rubles.
Which filter is better - carbon or regular?
A carbon filter more effectively purifies the air from gases and odors, so it is preferable for urban use. A regular paper filter is cheaper, but is only suitable for clean regions. If you often sit in traffic jams or drive on dusty roads, take a coal one.
How much does it cost to replace a cabin filter at a service center?
At official dealerships Nissan for replacement they charge from 800 to 1,500 rubles (excluding the cost of the filter). In independent services the price is lower - 300–600 rubles. However, the procedure is so simple that it is easy to do it yourself.
Is it possible to wash the cabin filter?
No, the filter cannot be washed. Once wet, a paper filter becomes deformed and loses its filtering properties, while a carbon filter stops absorbing odors. The only option for “resuscitation” is blowing with compressed air, but this is a temporary measure.
Why does the cabin still smell after replacing the filter?
If the smell remains, the problem may be in the air conditioner evaporator, where mold has accumulated. In this case, it will need to be cleaned with special means (for example, Liqui Moly Klima-Anlagen-Reiniger) or professional disinfection in the service.
