Comfortable stay in the car Nissan Terrano 2019 production directly depends on the quality of the air entering the cabin. Over time, the ventilation system can no longer cope with dust, odors and allergens due to clogging of the filtration element. Many crossover owners ignore this nuance, believing that replacement is necessary only if there is a clear smell of dampness, but this misconception can lead to serious problems.
Regularly changing consumables is not just a recommendation, but a necessity to maintain the health of the driver and passengers. A clogged filter creates resistance to air flow, causing the climate control fan to work at its limit, making noise and consuming more energy. In the conditions of Russian roads, where dust and reagents on asphalt are the norm, the replacement interval is reduced significantly compared to the standards stated by the manufacturer.
Replacement procedure for Nissan Terrano 2019 does not require special tools or deep knowledge of auto electrics. This is one of the most accessible operations to perform independently, which takes from 15 to 25 minutes of free time. The main thing is to know the exact location of the compartment and follow the sequence of actions so as not to damage the fragile plastic elements of the case.
Choosing the right consumables for Nissan Terrano
Before you begin dismantling the old element, you need to decide on the type of new filter. There are two main types on sale: regular coal and polyfill (synthetic). Conventional filters trap large dust, but allow odors and small allergens to pass through. Coal models contain activated carbon, which effectively neutralizes exhaust gases and unpleasant odors from the street.
For Nissan Terrano 2019, which is often used in urban environments with high levels of air pollution, the most appropriate choice would be carbon filter. It provides better protection for the respiratory tract of passengers and prevents fogging of windows in rainy weather, as it allows better air flow with less pollution. However, it is worth considering that coal models are more expensive than conventional analogues.
- 🛠️ Original: Article 27277-4BA0A (guaranteed quality, high price)
- 🛡️ High-quality analogues: Mann-Filter, Mahle, Corteco (excellent price-quality ratio)
- 💰 Budget options: Filtron, Big Filter (suitable for rare replacements, but lower efficiency)
When purchasing, pay attention to the integrity of the packaging and the presence of a rubber seal around the perimeter. If the rubber band is missing or deformed, the filter will allow untreated air to pass by, nullifying all efforts to clean the interior. Also check the rigidity of the frame: it should retain its shape when pressed in order to fit snugly into the seat.
⚠️ Attention: Do not buy filters without packaging or with damaged corners - this often indicates defective or improper storage, which will lead to rapid destruction of the material during installation.
Tools and preparation for replacement
You don't need a garage with a lift or a set of professional wrenches to get the job done. The entire process can be carried out in the parking lot or in the yard. The main tool you will need is Phillips screwdriver with cross tip PH2. Sometimes a flathead screwdriver can be useful to carefully pry up the latches if they have become stuck over time.
Before starting work, it is recommended to clear the area around the glove compartment from small debris and dust. This will prevent dirt from entering the ventilation system when the lid is opened. It is also worth preparing gloves to avoid getting your hands dirty on the old filter, which may be saturated with grease and road dust. If you change the filter in the cold season, let the interior warm up a little so that the plastic becomes more elastic.
- 🔧 Phillips screwdriver (size PH2) - the main tool for unscrewing screws
- 🧤 Protective gloves - for hygiene and protection of hands from dirt
- 🧴 Wet wipes - for wiping the seat before installing a new element
Make sure the vehicle is parked on a level surface and the handbrake is set. The engine must be turned off and the keys must be out of the ignition. This will prevent the fan from accidentally turning on or changing the climate control settings during operation. If your vehicle has a Start/Stop system, make sure it is completely de-energized.
⚠️ Attention: If you change the filter in winter, the plastic housing may become brittle. Be careful not to break the latches when attempting to open the cover.

Step-by-step instructions for removing the old filter
The process begins with freeing access to the filter compartment. On Nissan Terrano 2019, the filter is located directly behind the glove box (glove compartment). You need to open the glove compartment door and disconnect the restrictor cables or stops that prevent it from opening completely. This is usually done by simply pressing on the plastic clips on the sides.
Once the glove compartment is lowered down, you will see a plastic cover covering the filter housing. It is attached with several self-tapping screws. You need to carefully unscrew them with a Phillips screwdriver. Do not use excessive force to avoid stripping the threads in soft plastic. It is better to immediately put the unscrewed screws in a pocket or on a clean surface so that they do not fall into the niche under the panel.
- 🔓 Open the glove box and remove the side guards
- 🔩 Unscrew 3-4 screws securing the filter cover
- 🗑️ Remove the old filter by pulling it towards you by the edge
☑️ Preparation for replacement
When removing the old element, be extremely careful. If the filter is very dirty, a cloud of dust may fly out when you remove it. It is recommended to lightly spray the old filter with water from a spray bottle before removing it to prevent dust from flying around the cabin. After removal, inspect the planting area for debris, leaves, or evidence of rodent activity.
If you find foreign objects inside the case, be sure to remove them. A stuck branch or leaf can block airflow or damage the fan impeller when turned on. Wipe the interior cavity with a damp cloth to remove accumulated dust and dirt. This will also improve your cabin air quality once the new filter is installed.
What to do if the lid does not open?
If the cover does not budge, check whether the locking mechanism is jammed. Sometimes wiggling the panel slightly or using a flathead screwdriver to gently pry out the latches helps, but be careful not to leave any dents in the plastic.
Installing a new filter and installation nuances
Before installing a new filter, carefully study the arrows on its frame. They indicate the direction of air flow. For Nissan Terrano the correct direction is that the arrow should point down, that is, the air flows from top to bottom through the filter. If the element is installed incorrectly, it will quickly clog and stop letting air through, creating noise and stress on the stove motor.
Insert the new filter into the housing until it stops. It should fit tightly, without gaps around the perimeter. Make sure that the sealing rubber is evenly adjacent to the walls of the case. If the rubber band does not press, you may have chosen the wrong size filter or it may have become deformed during storage. In this case, it is better to take your time and find a suitable analogue.
- 🔽 Arrow direction: should point downwards (towards the floor)
- 🔍 Check the seal: the elastic band should fit snugly against the body
- 🛠️ Fixation: the lid must close without distortions or cracks
After installing the filter, return the cover and tighten the screws. Don't over-tighten them, just make sure they're secure enough to prevent the plastic from cracking. Replace the glove box restraints and close it. Open and close the glove compartment several times to make sure it moves smoothly and there are no unusual sounds.
Turn on the ventilation system to maximum power and check operation. Listen for any unusual noises, whistles or vibrations. Air should flow evenly from all deflectors. If you smell a burning smell or hear a strange noise, turn off the system immediately and check that the filter is installed correctly.
⚠️ Attention: Incorrect installation of the filter (arrow up) can lead to rapid failure of the stove fan due to increased air resistance.
Before installing the new filter, bend it slightly at the edges to make it fit into the narrow seat more easily, but do not overdo it so as not to damage the carbon layer.

Please note that part numbers may vary depending on region and vehicle year. Before purchasing, always check the part number against the markings on the old filter or use your vehicle's VIN in parts catalogs. This will eliminate the risk of purchasing the wrong item.
Some owners prefer to install filters with improved filtration, which have additional layers or a denser structure. However, such filters may create more resistance to air flow, requiring more frequent replacement. It is important to find a balance between air purity and system throughput.
Using high-quality analogues from well-known brands such as Mann or Mahle often gives better cleaning results than the original Nissan filter, at a lower cost.
Common replacement mistakes and how to avoid them
One of the most common mistakes is installing the filter backwards. As mentioned, the direction of airflow is critical. If you install the filter incorrectly, it will not be able to effectively trap contaminants, and the pressure in the ventilation system will increase sharply. This will reduce the performance of the air conditioner and furnace.
Another mistake is ignoring the state of the footprint. If you do not clean the housing of dust and debris before installing a new filter, some of the dirt will immediately fall on the fresh element, shortening its service life. Dirt can also get into the ventilation system, causing unpleasant odors and noise.
- ❌ Error 1: Installing a filter without taking into account the direction of the arrow
- ❌ Mistake 2: Ignoring cleaning the case from dust before installation
- ❌ Mistake 3: Tightening the screws too tightly, leading to plastic cracks
You should also avoid using filters that do not have a rigid frame. Soft filters can become deformed by air pressure, causing them to fall out of the housing or create gaps. Always check the rigidity of the frame before purchasing by squeezing it with your fingers.
Some drivers try to extend the life of the filter by trying to wash or vacuum it. This is unacceptable for disposable models, since the structure of the material is destroyed and it loses its filtering properties. You can only wash special reusable filters that require regular treatment with special sprays.
What happens if you forget about the elastic band?
If the rubber seal is missing or damaged, air will flow past the filter without being cleaned. This will lead to dust and dirt getting into the interior, as well as fogging up the windows.
Replacement dates and signs of contamination
The manufacturer recommends changing the cabin filter every 15,000 - 20,000 kilometers or once a year. However, in real operating conditions, especially in megacities or on dusty roads, this interval should be reduced to 10,000 kilometers. Regularly checking the condition of the filter will help avoid problems with the ventilation system.
The main sign of contamination is a decrease in the intensity of air supply from the deflectors even at maximum fan speed. An unpleasant smell of dampness or mustiness may also appear in the cabin, which cannot be eliminated by ventilation. If the glass fogs up much faster than usual, this may also indicate a clogged filter.
- 📉 Reduced air flow is the main sign of the need for replacement
- 👃 Unpleasant odor in the cabin is a consequence of the proliferation of bacteria in the filter
- 💨 Rapid fogging of windows - disruption of air circulation
During rainy weather, a clogged filter can cause water to pool in the ventilation system, causing corrosion and mold. Therefore, at the first sign of contamination, do not delay replacement. This is a simple procedure that will save your health and extend the life of your air conditioning system.
Regularly replacing the filter every 10,000 km in urban environments is the key to clean air and long-term operation of the climate control system.
Frequently asked questions (FAQ)
Is it possible to install a filter without a carbon layer?
Yes, you can. A regular filter traps dust but does not neutralize odors. If you drive mostly outside the city and don't smell exhaust fumes, a regular filter will do. However, for city driving, a carbon filter is preferable.
How often should you change the filter on your Nissan Terrano 2019?
The official recommendation is once a year or 20,000 km. But in dusty roads and cities, it is better to change it every 10,000 km or even more often if you notice a decrease in air flow or the appearance of odors.
What should I do if the filter does not fit into the housing?
Check the correct model and installation direction. The filter may be deformed or the wrong model has been selected. Do not use force to avoid breaking the plastic of the case. It is better to return the filter to the store and replace it with a new one.
Is it possible to extend the life of the filter with a vacuum cleaner?
No, it's ineffective. The vacuum cleaner only removes surface dust, but does not restore the properties of the material. Once contaminated, disposable filters lose their properties and require replacement.
Do I need to remove the battery when replacing the filter?
No, you do not need to disconnect the battery. The work is performed in the mechanical part of the cabin and does not affect the electrical system of the car.
