Where is the cabin filter on a Nissan Note: complete replacement instructions

Owners of a compact hatchback Nissan Note often face the need to maintain air conditioning and ventilation systems, but do not always know the exact location of the filtration elements. Many car owners mistakenly believe that access to the filter is through the engine compartment, as on many other cars, which leads to wasted time and unnecessary searches. In fact, the design Nissan Note (especially the first generation E11 and restyled E12) has its own characteristics that require access from the cabin or from under the instrument panel.

Understanding where the filter is hidden is critical to maintaining a healthy vehicle climate, especially in dusty or humid conditions. Ignoring this procedure results in the air entering the cabin carrying dust, mold spores and unpleasant odors, which directly affects the health of passengers. In this article we will analyze in detail the location of the element for different generations of the model Nissan Note, we will provide a step-by-step replacement algorithm and tell you how to choose the right consumables.

Filter location depending on car generation

The answer to the question about the location of the filter directly depends on the year of manufacture of your car and the technical revision of the body. For the first generation Nissan Note (model range E11, produced from 2005 to 2013) the element is located in a specific area under the passenger seat or behind the decorative trim in the front passenger's feet. This is a non-trivial solution for engineers, which often confuses beginners who are accustomed to classic layouts.

In more modern versions such as the second generation Nissan Note (E12) and its restyled modifications, the design was changed for ease of maintenance. Here, the manufacturer moved the installation location closer to standard solutions, placing the compartment under the glove compartment on the passenger side. It is important to note that in some trim levels with the system Double Flow or a reinforced climate control system, two filters can be provided: one for the air conditioning system, the second for interior ventilation, which doubles the amount of work.

Don't forget about hybrid modifications Nissan Note e-Power, where the interior layout may differ due to the location of additional battery packs under the floor. In such cases, access to the filter may be a little more difficult, requiring the removal of additional floor coverings. Always check the technical documentation specifically for your VIN code, since even within the same model year there could be changes in equipment.

⚠️ Attention! If you are unsure of the generation of your car, look at the VIN number on the vehicle's registration plate or on the placard under the windshield. An error in determining the generation can lead to the purchase of a filter of the wrong size, which simply will not fit into the socket.

To quickly navigate through the types of location, we provide a comparison table that will help you navigate before starting work.

Model generation	Years of manufacture	Main location	Difficulty of access
Nissan Note E11	2005–2013	Behind the plastic trim under the passenger seat	Average
Nissan Note E12 (before restyling)	2013–2016	Under the glove box (glove compartment)	Low
Nissan Note E12 (facelift)	2016–2020	Behind the glove box or under the dashboard	Low
Nissan Note e-Power	2016–present	Under glove box (may require floor removal)	High

Correct location determination is already half the success. Do not try to use force if the element does not give in, as the interior plastic Nissan Note Quite fragile and can crack if handled carelessly. If access is blocked by additional shields, carefully inspect them for hidden fasteners or latches.

Necessary tools and preparation for replacement

Before you begin dismantling interior elements, you need to prepare a working set of tools. In most cases, to replace the filter with Nissan Note no professional car service is required, and all work can be done yourself in a garage or parking lot. However, having the right equipment will significantly speed up the process and prevent damage to fragile plastic parts.

You will need a set of screwdrivers that includes both flathead and Phillips bits, since decorative trims can be attached using different types of screws. It would also be useful to have a plastic spatula for removing the clips, so as not to scratch the upholstery or break the clips during dismantling. To work in the dark or poor lighting, be sure to take a flashlight, as the filter compartment is often located in a deep niche.

• 🔧 Phillips screwdriver (size PH1 or PH2) for unscrewing screws.
• 🔧 Flat screwdriver or plastic spatula for prying up the latches.
• 🔧 Flashlight (preferably a headlamp to free your hands).
• 🔧 Vacuum cleaner with a narrow nozzle for pre-cleaning the compartment.
• 🔧 New filter (check the article matches).

It is also important to prepare the work space: move the front passenger seat as far back as possible to provide easy access to the legs and the lower part of the panel. If you are working with the first generation, where the filter is under the seat, make sure that the floor under the car is clean so that when removing the trim, dirt does not get into the interior. Purchase a new filter in advance so as not to interrupt the process for a trip to the store.

⚠️ Attention! Never use sharp metal tools to pry up plastic panels unless you have a plastic spatula handy. This is guaranteed to lead to deep scratches and chips on the decorative elements of the interior. Nissan Note.

If you plan to replace during the colder months, make sure the room is warm enough to prevent the plastic from becoming too brittle. Cold plastic at Nissan Note is especially susceptible to brittleness, and one extra attempt to move the latch can lead to a crack, which will then have to be repaired at great cost and time.

Step-by-step replacement instructions for Nissan Note E11

For first generation owners Nissan Note the replacement process has its own specifics, since the filter is hidden in an area that is not obvious to most drivers. You will need to remove the plastic trim located under the front passenger seat, which blocks access to the interior cavities of the body. This requires accuracy and consistency of actions.

First, move the seat as far forward as possible to gain access to the rear of the pad. Inspect the underside of the floor covering and the plastic shield covering the area under the seat. It is usually secured with several plastic clips and perhaps one or two self-tapping screws. Gently pry the clips open with a flathead screwdriver wrapped in a soft cloth to avoid damaging the paint or plastic.

• 📍 Remove the seat or move it to its extreme position.
• 📍 Find and unscrew the screws securing the bottom trim (if any).
• 📍 Remove the plastic screen by snapping the clips around the perimeter.
• 📍 Open the lid of the filter compartment located in the depths of the niche.

After removing the cover you will see a plastic filter housing. It can be closed with a lid that is secured with latches. Open the cover, remove the old element and carefully inspect its condition. If it is black, clogged with dust, or shows signs of mold, replacement was necessary. Pay attention to the airflow direction indicated by the arrows on the housing.

Insert the new filter strictly in the direction of the air flow. An installation error can lead to a decrease in the efficiency of the air conditioner and an increase in the load on the fan. Make sure the filter fits tightly and has no gaps that could allow unfiltered air to enter the system.

⚠️ Attention! When assembling the under-seat trim, make sure that all the clips are in their proper locations. If the clip remains in the panel and not in the body, the trim will hang loose and make an unpleasant knock when driving over uneven surfaces.

After installing the new element, return the cover to its place and secure the screws. Check the operation of the air conditioner and ventilation, making sure that the air is supplied evenly and without foreign odors. This completes the procedure for the first generation.

Difficulty removing E11 trim

Sometimes the clips on the pad under the seat become stuck with dirt. If it does not budge, do not use excessive force. Try rocking the panel slightly from side to side or spraying the mounting area with penetrating lubricant (WD-40), but be careful not to get it on the seat upholstery.

Replacement procedure for Nissan Note E12 and restyling

On the second generation Nissan Note the procedure becomes more standard and intuitive, since the manufacturer has located the filter behind the glove box (glove box). This solution simplified maintenance and made it accessible to most car owners without special skills. However, even here there are some nuances that are worth considering.

First, open the glove compartment and clear it of all things. You need to find the glove box door opening limiters. These are usually plastic pins on the sides that prevent the door from opening too wide. Press down on these stops (or bend them if they are flexible) so that the glove compartment door can drop all the way down, allowing access to the rear wall.

• 🔓 Lower the glove box completely to a horizontal position.
• 🔍 Inspect the right and left sides of the glove compartment body for the presence of latches.
• 🔧 Unclip the latches to remove the glove box housing (if required).
• 🔦 Find the filter cover located behind the glove compartment mounting area.

Behind the glove compartment you will see a rectangular plastic cover covering the filter compartment. It is usually held in place by one or two latches. Open the lid, remove the old filter and check for debris or leaves in the compartment. If there is dirt, carefully remove it with a vacuum cleaner or damp cloth.

Install the new filter, observing the direction of the air flow arrow. Make sure that the rubber seal around the perimeter of the filter fits tightly to avoid suction of untreated air. Close the compartment lid and return the glove box to its place by latching the stoppers.

It is important to check that the glove compartment closes tightly and is not loose. If it doesn't lock into place, you may have not fully latched the stops or may have misaligned the case during installation. Repeat the procedure if difficulties arise.

⚠️ Attention! If you have the system installed Double Flow, the compartment can contain two filters: upper and lower. Be sure to replace both elements to ensure proper operation of the driver/passenger split air conditioning system.

Choosing the Right Filter and Specifications

Choosing a high-quality filter is the key to not only air purity, but also the durability of the ventilation system Nissan Note. There are many analogues on the market, but it is important to understand the difference between the types of filters and their characteristics. A standard carbon filter effectively traps odors and fine dust, while conventional paper filters only handle large particles.

For Nissan Note It is recommended to use activated carbon filters, as they provide better protection against exhaust gases and outside odors. Pay attention to the article numbers of original spare parts: for E11 this is often 27277-AX00A, and for E12 - 27277-4CA0A. However, there are also high-quality analogues from brands like Mann-Filter, Purflux or Sakura, which can be cheaper than the original without losing quality.

When choosing, pay attention to the density of the material and the presence of additional layers. A good filter should have a pleated structure that increases the filtration area. It is also important to check the presence of a rubber frame, which ensures a tight fit into the case. The absence of a frame can cause air to bypass the filter, making replacement pointless.

• ✅ Original filter Nissan - guarantee of perfect fit, but high price.
• ✅ Coal analogues are the best choice for a city with active traffic.
• ✅ Paper analogs are a budget option, but less effective against odors.
• ✅ Anti-allergenic filters - contain special additives to protect against allergens.

Do not skimp on this element, as a bad filter can lead to contamination of the air conditioner evaporator, which will require expensive cleaning of the system. If you live in a region with high dust levels or frequent traffic jams, change the filter more often than the manufacturer recommends - every 10-15 thousand kilometers.

Common mistakes and how to avoid them

Even with a simple replacement procedure, car owners often make mistakes that can lead to negative consequences. One of the most common mistakes is installing the filter backwards. There is always an arrow on the filter housing indicating the direction of air flow, and ignoring this sign negates the entire efficiency of the ventilation system.

Another common problem is damage to the plastic latches when dismantling the panels. Haste and the lack of a tool (plastic spatula) lead to fragile fasteners breaking, and the panel begins to dangle or rattle. This not only spoils the appearance, but can also lead to squeaks in the interior when driving.

It is also worth noting the error associated with ignoring cleaning the compartment before installing a new filter. If you leave old debris, dust and leaves inside the housing, the new filter will quickly become clogged, and an unpleasant putrid odor may appear in the cabin. Always take the time to pre-clean.

And one more important point: do not leave tools or fasteners in the compartment after completion of work. A forgotten screwdriver or self-tapping screw can get into the fan, which will lead to its breakdown and loud noise when the air conditioner operates. Double check the compartment before closing the lid.

⚠️ Attention! If you notice less air flow after replacing the filter, the filter may be installed incorrectly or may be defective. Check the installation immediately, as poor circulation may cause the windows to fog up and reduce driving safety.

Remember that regular maintenance is the key to comfort and health. Don't put off replacing the filter until later, especially if you notice an unpleasant odor or a decrease in the efficiency of the air conditioner. This is a simple procedure that will save you money on system repairs in the future.
