Vehicle ventilation and air conditioning system Nissan Note first generation (body E11) plays a critical role in creating a comfortable microclimate. Over time, the air intake becomes clogged with dust, lint and leaves, which reduces the efficiency of the air conditioning system and deteriorates the air quality in the cabin. Regular replacing the cabin filter - This is a simple procedure that you can perform yourself without contacting a service center.
Many owners Nissan Note E11 neglect this maintenance, believing that replacement is required only when there is a clear smell of rot or strong fan noise. However, a clogged element creates excessive resistance to air flow, forcing the stove motor to work under increased load. This not only reduces heating power, but can also lead to premature failure of the heater motor, the repair of which will require significant financial costs.
Types of filters and their effect on the climate system
For car Nissan Note first generation two main types available cabin filters: coal and regular paper. A conventional filter, consisting of compressed cellulose, effectively traps large dust, insects and leaves, but practically does not cope with the smallest allergens and harmful gases. The carbon filter contains activated carbon, which adsorbs exhaust odors, nitrogen oxides and sulfur oxides, making the air in the cabin much cleaner.
When choosing consumables, it is important to consider the quality of the raw materials. Cheap analogues often have a weak structure that can collapse under air pressure, allowing dust to enter the ventilation system. Original filter Nissan or quality certified substitutes provide an optimal balance between filtration and throughput. If you often drive in traffic jams or in industrial areas, install carbon filter is a prerequisite for maintaining the health of passengers.
The service life of the element is also a significant factor. Even the most expensive carbon filter loses its properties after 10–15 thousand kilometers, since the carbon stops adsorbing substances and can begin to release them back. In dusty climates or frequent driving on dirt roads, this interval is halved. You should not save on your health by ignoring a visual inspection of the element at every oil change.
- 🔹 Carbon filters: ideal for the city and fighting odors, but have a slightly lower throughput.
- 🔹 Paper filters: cheaper, better air permeability, but do not protect against toxic gases and odors.
- 🔹 Anti-dust filters: special options with electrostatic spraying to retain small particles.
Filter location and preparation for replacement
In body structure Nissan Note E11 The location of the cabin filter is thought out quite well for self-service, although access to it requires some manipulation. The element is located behind the glove compartment on the front passenger side. You don't have to remove the dashboard or disassemble the dashboard, which greatly simplifies the process and saves time.
Before starting work, you need to prepare the car: turn off the engine, open the hood to provide ventilation and disconnect the battery terminal (this is optional, but recommended for safety when working with electricians). Make sure there are no valuables in the glove compartment that could fall out during removal. You will need a flat-head screwdriver or a plastic spatula to gently pry out the clips without damaging the interior plastic.
It is important to understand that the design of the clamps is Nissan Note the first generation may stick or break over time due to temperature changes. Act smoothly and without excessive effort. If the plastic is stuck, try warming it up a little with a hairdryer or carefully prying the retainer with a thin tool. Broken latches will require subsequent repairs or the use of zip ties to hold the lid in place.
⚠️ Caution: Do not use excessive force when removing the filter cover, as the plastic clips are fragile. Nissan Note E11 breaks easily, which can lead to extraneous noise in the cabin when driving.

Step-by-step instructions for replacing an element
The replacement process begins with completely emptying the glove box. Open it and remove all contents. Next, locate the glove compartment door travel stop - this is a plastic pin that rests against the body when fully open. Gently wring it out and lower the glove compartment all the way down so that it hangs on its hinges. This will open access to the back wall of the drawer, where the filter cover is located.
On the back you will see a rectangular plastic cover held in place by latches. Depending on the year of manufacture and configuration, the latches can be located on the top, bottom or sides. Press them sequentially until the cover is released. Remove the old filter and carefully inspect its condition. If you see a layer of dust several millimeters thick or traces of mold, this confirms the need for urgent replacement.
Before installing a new element, be sure to clear the niche of debris. Often leaves and dirt accumulate in this pocket, which can enter the ventilation system when the filter is removed. Use a vacuum cleaner or compressed air to blow out any remaining dust. Make sure that the rubber sealing frame on the lid is not damaged or has lost its elasticity.
☑️ Preparation and dismantling
Installing a new filter requires attention to the direction of air flow. There is always an arrow on the element body with the inscription Air Flow or Up. The arrow should point down towards the heater motor. If the filter is installed incorrectly, the cleaning efficiency will drop sharply and the air flow resistance will increase. Insert the filter all the way and close the lid, making sure that all latches engage.
⚠️ Attention: Incorrect installation of the filter (arrow up) will result in air passing through the side slots, bypassing the filter material, which will negate the entire replacement procedure.
Replacement frequency and signs of contamination
Manufacturer Nissan recommends changing the cabin filter every 15,000 kilometers or once a year, whichever comes first. However, actual operating conditions often dictate more stringent deadlines. If the car is operated in a metropolis with high levels of air pollution or in rural areas with a lot of dust, the interval should be reduced to 7,000–10,000 kilometers.
There are clear signs that indicate that the filter requires immediate replacement. The most obvious of them is the appearance of an unpleasant odor in the cabin when the fan or air conditioner is turned on. A damp or musty smell indicates the development of bacteria and mold on the surface of the wet filter. Another sign of contamination is a decrease in airflow intensity, when even at maximum fan speed the air blows weakly.
Another warning sign is glass fogging in rainy weather. A clogged filter prevents the system from effectively drying the air, causing moisture to condense on the windshield, impairing your visibility. If you notice that your windows are fogging up faster than usual, check the condition of the filter first. Ignoring this symptom may lead to an accident due to poor visibility.
- 🔹 The smell of rot: a signal about the presence of mold and bacteria inside the filter.
- 🔹 Weak airflow: the filter is so clogged that it blocks the air flow.
- 🔹 Fogging of glass: the system cannot effectively dry the incoming air.
Comparison of original and analog filters
The auto parts market offers a wide selection of filters for Nissan Note E11, which often confuses owners when choosing. Original filter from Nissan guarantees ideal compliance with the dimensions and declared filtration characteristics, but its cost may be inflated compared to analogues. Often, under the original packaging there are hidden products from the same manufacturing plants as analogues, but with a higher markup for the brand.
Analog filters from trusted manufacturers such as Corteco, Mann-Filter, Knecht or Sakura, often surpass the original in quality of materials and design. They may have a denser structure, hold dust better and have an improved carbon layer. However, it is important to avoid cheap fakes that do not have quality certificates and can emit harmful substances when heated.

Elimination of odors and prevention
If after replacing the filter the unpleasant odor in the cabin does not disappear, the problem may lie not only in the element itself, but also in the air conditioner evaporator. Over the years of operation, a layer of dirt and bacteria accumulates on the surface of the evaporator, which continues to emit an odor even with a clean filter. In this case, a disinfection procedure for the air conditioning system is required.
To remove odors, you can use special aerosol cleaners for air conditioners. Spraying is done through the air ducts or drainage hole, which allows the antibacterial composition to penetrate to the evaporator. However, for deep cleaning, it is better to turn to professionals who use ozone generators or steam units to completely destroy bacterial colonies.
Pollution prevention includes regularly ventilating the interior and turning off the air conditioning a few minutes before stopping the engine. This allows the evaporator to dry out, preventing condensation and mold growth. It is also recommended to regularly check the condition of the drain tube to ensure that water does not accumulate in the engine compartment area and does not enter the passenger compartment.
⚠️ Attention: Regular use of the air conditioner in recirculation mode without ventilation leads to rapid accumulation of moisture and the development of fungus in the ventilation system, which is extremely difficult to remove without complete disassembly.
Before winter, always replace the filter with a new one to avoid fogging up the windows and ensure effective heating of the interior during the cold season.
Common maintenance mistakes
Despite the simplicity of the procedure, owners Nissan Note often make mistakes that can lead to problems in the future. The most common mistake is neglecting to clean the filter niche. Debris left in a pocket can get into the fan and cause it to jam or make noise when operating. Also, many people forget about the orientation of the air flow arrow, which reduces the filtration efficiency to zero.
Another common problem is using the wrong size filters. Cheap analogues sometimes have errors in geometry, which is why the filter is inserted tightly or, conversely, dangles, allowing dirt to pass through the edges. Always check the size of the new element before installation and compare it with the old one. If the filter does not fit into the niche, do not try to force it in - look for another model.
Sometimes owners try to extend the life of the filter by trying to wash or vacuum it. This is unacceptable for paper and carbon filters: water destroys the structure of the fibers and carbon layer, and a vacuum cleaner cannot remove contaminants from deep within the material. Such a filter will become a source of mold and bacteria. The only correct solution is a complete replacement with a new element.
A high-quality replacement of the cabin filter is not just a replacement of consumables, but an important part of the prevention of the air conditioning system and the health of passengers.
