Polluted air in a car is not just a discomfort, but a real threat to the health of the driver and passengers. On Nissan Almera G15 the ventilation system works effectively, but only if it is in good working order and clean cabin filter. Over time, it becomes clogged with dust, grime, grime and allergens and ceases to perform its functions.
Many owners of this sedan mistakenly believe that replacing the filter is a complicated procedure that requires a visit to a service center. In fact, the process takes no more than 15-20 minutes if you have a minimum set of tools and basic knowledge about the design of the car. Regular replacement air purification filter Extends the life of the air conditioning and heating system.
In this article we will look in detail at how to carry out this operation yourself, what types of filters exist and what to look for when choosing. We will also touch on nuances that beginners often miss, leading to incorrect installation and reduced efficiency of the climate system.
Why change the filter on Nissan Almera G15 and when to do it
Main function cabin filter — retain solid particles entering the cabin along with the air flow through the intake system. If the element is clogged, the air flow is weakened, which leads to poor glass flow and slow heating or cooling of the interior. Owners Nissan Almera G15 They often notice that the fan is louder than usual, but little air is flowing.
In addition to reducing performance, a dirty filter becomes a breeding ground for bacteria and mold. The moisture that accumulates in the air conditioning system mixes with dust and organic matter, forming an ideal environment for the proliferation of microorganisms. This causes an unpleasant odor to appear, which is felt immediately after turning on the ventilation system.
The manufacturer recommends replacement air purification filter every 15,000 kilometers or once a year, whichever comes first. However, in an urban environment with high levels of gas pollution and a lot of dust, this interval should be reduced to 10,000 kilometers. The frequency of replacement directly depends on the operating conditions of the vehicle.
- 🚗 Dusty roads and unpaved areas require more frequent inspection and replacement of the element.
- 🏙️ City operation with high traffic clogs the filter with soot and exhaust gases faster.
- 🌲 Operation during the flowering season may cause allergic reactions when using an old filter.
⚠️ Attention: Ignoring filter replacement can lead to damage to the heater motor due to overload, as it has to work with increased load, pushing air through the clogged element.
Which filter to choose: carbon or regular
When selecting a new item for Nissan Almera G15 The owner is faced with the question: what type of filter is better to purchase? There are two main types: conventional mechanical filters and carbon filters. Mechanical options perform the function of rough cleaning, trapping large dust, fluff and leaves. They are cheaper and do basic tasks well.
Carbon filters contain a layer of activated carbon, which not only traps particles, but also adsorbs harmful gases and odors. This is especially true for drivers who often sit in traffic jams or follow trucks. Coal layer effectively neutralizes nitrogen and sulfur oxides, protecting passengers' lungs from harmful exhaust gases.
Experts strongly recommend installing carbon filters for Nissan Almera G15, as they provide a higher level of comfort. The difference in price between the conventional and coal options is usually small, but the difference in the quality of air purification is significant. However, it is worth considering that a carbon filter creates greater aerodynamic drag, so it may be a little more demanding on the cleanliness of the air intake system.
- 🌿 Carbon filters better protect against exhaust odors and industrial pollution.
- 💰 Conventional filters are cheaper, but do not retain toxic gases, letting them into the cabin.
- 🛡️ For allergy sufferers and people with respiratory diseases, the charcoal option is a must-have choice.
When purchasing, be sure to check the manufacturer's markings. Original filter for Nissan Almera has a catalog number, which can be found in spare parts catalogues. Low-quality analogues may have incorrect dimensions or a weak frame, which will lead to deformation and the passage of unpurified air.
⚠️ Attention: Cheap non-original filters often use low-quality carbon, which over time can begin to release harmful substances or simply stop working, turning into ordinary paper.

Necessary tools and preparation for replacement
Filter replacement procedure Nissan Almera G15 does not require complex special tools. You will need a minimum set, which almost every motorist has. The main tool is a flat screwdriver or a special spatula for removing plastic clips. A flashlight may also come in handy since the filter location is in a dark corner.
Before starting work, it is necessary to prepare a new product. Check its integrity and make sure that the air flow direction arrow on the filter housing is correct. Installation errors may result in the filter not fitting tightly to the seat, and air will bypass the cleaning element.
It is also advisable to have a vacuum cleaner or compressed air on hand to pre-clean the cavity of debris that may have accumulated during the operation of the old filter. This will help prevent dirt from getting inside the ventilation system when removing the old element. If you are replacing in cold weather, allow the machine to warm up so that the plastic is not too brittle.
☑️ Preparation for replacement
Step-by-step instructions for removing the old filter
Removing the filter from Nissan Almera G15 carried out from the passenger seat. You need to open the glove compartment (cup holder) and inspect the inside. In the upper part, closer to the dashboard, you will see a rectangular cover closed with latches. This is access to the body cabin filter.
To remove the cover, you must carefully press the latches. They are located on the sides of the lid. Use a flathead screwdriver covered with a cloth to avoid scratching the plastic. Press the latches on both sides and pull the cover towards you. Movements must be smooth so as not to break the fragile plastic antennae.
After removing the cover you will see the filter itself. It is usually in a plastic frame or simply inserted into slots. Gently pull it towards you. If the filter is severely clogged and stuck, do not use excessive force as this may damage the fan housing or guides. It's best to rock it slightly from side to side to loosen the grip.
- 🔧 Open the glove compartment all the way and find the filter cover at the top of the compartment.
- 🔩 Carefully press out the side clamps using a flat-head screwdriver.
- 🌬️ Remove the old filter by pulling it towards you by the edge, being careful.
What to do if the cover does not come off?
If the latches are stuck, do not try to break them. Try opening the glove compartment slightly from a different angle, or use a plastic card to pry open the latches. Strong pressure can lead to cracks in the plastic, which will then have to be glued together or the lid replaced completely.
Installation of a new filter and final checks
Before installing a new element, be sure to clear the cavity of dust and debris. Use a vacuum cleaner or simply wipe the area with a damp cloth. Make sure there are no leaves or insects in the compartment that could have entered through the air intake system. Cleanliness of the seat is the key to tightness and proper operation of the system.
Insert the new filter into the grooves, strictly observing the direction of the air flow. There is always an arrow on the filter housing indicating which direction the air should move. Normally the arrow should point down or towards the engine, but Nissan Almera G15 It is important to follow the markings on the item itself. An error in direction reduces the cleaning efficiency significantly.
After installing the filter, return the cover to its place and snap the latches into place. Make sure the lid fits tightly and does not loosen. Close the glove compartment and check the operation of the ventilation system. Turn on the air conditioner or furnace at maximum power and listen for any extraneous noise. The air should flow evenly and odorless.
Before finally installing the cover, check that the filter is not twisted or the edge is pinched. This may cause the latches to not engage fully and the lid to open while moving.
If you did everything correctly, you will immediately notice an improvement in the performance of the ventilation system. The air flow will become stronger, and foreign odors will disappear in the cabin. Replacing the cabin filter - This is one of the simplest and most effective car maintenance procedures that can be easily done with your own hands.
Typical errors and operating tips
One of the most common mistakes is installing the filter in the wrong direction. Many drivers simply insert the element into the grooves, not paying attention to the arrow. This leads to the fact that the filter material works in reverse, and its efficiency drops to almost zero. Airflow direction must always match the air flow in the system.
Another mistake is using the wrong size filter. If the filter is too large, it may not fit or may become deformed, creating gaps. If it is too small, air will bypass the filter material. Always check the dimensions of the new element with the old or catalog number. For Nissan Almera G15 There are specific sizes that cannot be replaced with analogues from other models without adaptation.
Don't forget to check the condition of the air intake system. Sometimes leaves and debris accumulate in the windshield area under the plastic grille. If you don't clean this area, debris will fall directly into the filter, clogging it much faster. Regular cleaning of the grille extends the life of the filter element.

Questions and answers on replacing the filter
Do I need to change the filter if there is no smell in the cabin?
Yes, replacement is necessary even if there is no smell. A dirty filter reduces the efficiency of cooling and heating, increases the load on the stove motor and allows small dust particles to pass through, which do not always smell, but are harmful to health.
Can I use a filter from another Nissan model?
No, the dimensions and shape of the filter housing are for Nissan Almera G15 unique. Using a filter from another model (for example, Sentra or Note) will result in poor sealing and ineffective air purification.
How often should you check the condition of the filter?
It is recommended to inspect the filter every 10,000 kilometers. If you see that it is heavily soiled, change it ahead of schedule. In dusty conditions it is worth checking more often.
What happens if you forget about the flow direction arrow?
The filter will not work efficiently, since the air flow will put pressure on the filter material from the back side, which can lead to its deformation and the passage of dirt. In addition, the flow resistance will increase and the fan will work under overload.
Is it possible to extend the life of the filter by shaking it out?
No, it's ineffective. The filter traps the smallest particles that cannot be removed by simply shaking them out. An attempt to clean it may damage the structure of the filter, and it will no longer retain dust. The filter is a consumable item and needs to be changed.
