This is the standard location for most crossovers Nissan-Renault, but access to it may vary depending on the configuration. In basic versions, the glove compartment can be easily removed, but in top versions (for example, with climate control), additional manipulations may be required.

To get to the filter you need to:

• 🔧 Open the glove compartment and empty it of its contents.
• 🔍 Find two plastic latches on the sides (they hold the glove compartment on the guides).
• 📍 Gently squeeze the latches and pull the glove compartment towards you - it will be removed from the mounts.
• 🚗 Behind the glove compartment you will see a plastic filter cover with the inscription AIR FILTER or a filter icon.

Important: in some versions Terrano The filter cover can be screwed on with self-tapping screws (usually Torx T20). If this is your case, prepare a screwdriver in advance.

Which cabin filter to choose for Nissan Terrano 2019?

There are three types of cabin filters on the market for Terrano:

• 🌿 Regular paper - the most budget option (from 300 rubles), it traps only large dust and insects, but does not cope with odors and germs.
• 🧴 Coal - middle price segment (600–1200 rubles), additionally absorbs harmful gases and unpleasant odors thanks to activated carbon.
• 🦠 Antibacterial/anti-allergenic - premium option (1200–2000 rubles), impregnated with a special composition that kills bacteria and fungi.

Original filter from Nissan has an article number 27277-JM00A (paper) or 27277-4M025 (coal). However, many owners choose analogues from trusted brands:

Brand	Article	Type	Price, rub.	Features
Mann Filter	CU 25003	Coal	800–1000	High density, good protection against dust and odors
Bosch	1 987 429 630	Antibacterial	1200–1500	Three-layer structure, anti-mould
Filtron	K 1321 A	Paper	350–500	Budget option, suitable for urban use
SCT	SA 2133	Coal	700–900	Good price/quality ratio, popular in Russia

When choosing, pay attention to filter size - it must match the original (240×200×30 mm). Also check if the filter has air direction arrows - this is important for correct installation. If you live in a metropolis or often get stuck in traffic jams, a carbon filter will be the best choice. For rural areas, paper is sufficient.

When should you change the cabin filter on a Terrano?

• 🌫️ Fogging of windows for no apparent reason (even with the air conditioner on).
• 👃 Unpleasant smell in the cabin, especially when the fan is turned on.
• 💨 Weak air flow from the deflectors at maximum fan speed.
• 🤧 Increased allergic reactions from the driver or passengers.

If you often drive on dusty roads, live in an industrial area, or regularly sit in traffic jams, the filter may become clogged after 8–10 thousand km. Owners of the 2019 Nissan Terrano note that carbon filters in Russian conditions last on average 10-12 months, and paper filters - no more than 6-8 months with intensive use.

⚠️ Attention: If you ignore replacing the filter, this can lead to breakdown of the heater fan (due to increased load), mold in the air ducts, and even problems with electronics due to high humidity in the cabin.

Step-by-step instructions: how to change the cabin filter on a Nissan Terrano 2019

To replace you will need:

• 🔧 Flat screwdriver (for prying latches).
• 🔨 Screwdriver Torx T20 (if the cover is self-tapping).
• 🧹 Vacuum cleaner or brush (for cleaning the case).
• 📦 New cabin filter.

Now let's start replacing:

1. Open the glove compartment and take out all the things from it. Press on the sides of the glove compartment to compress the latches and pull it towards you. On some trim levels, you may need to first lower the glove compartment down and then pull it out.
2. Remove the filter cover. It can be secured with latches or screws. If there are screws, carefully unscrew them and set them aside.
3. Take out the old filter. It may fit tightly - pull it by the edge, but do not tear it (so that dust does not fly around the cabin). Please note arrow direction on the filter - this will be useful when installing a new one.
4. Clean the case remove dust and debris with a vacuum cleaner or damp cloth. If mold is visible inside, treat the surface with an antiseptic (for example, Liqui Moly Klima-Anlagen-Reiniger).
5. Install a new filter, observing the direction of the air (the arrows should point down, towards the floor). Make sure the filter fits tightly without any gaps.
6. Close the lid and secure it (with latches or screws). Reinstall the glove compartment and check that the latches are engaged.

Are there any gaps between the filter and the housing?

Is the filter cover securely attached?

Is the glove box positioned correctly (are there any distortions) |

Does the fan work at all speeds-->

After installation, turn on the fan at maximum speed and check if there is any extraneous noise (for example, whistling). If everything is done correctly, the air flow should become noticeably stronger, and unpleasant odors should disappear.

What to do if the filter does not fit into place?

If the new filter does not fit into the slot, check:

1. Correct model (perhaps you bought a filter for a different modification Terrano).

2. Installation direction (arrows should point down).

3. Cleanliness of the grooves - sometimes an old filter leaves behind debris that prevents a tight fit.

If the problem persists, carefully bend the edges of the filter (no more than 2–3 mm), but do not overdo it so as not to tear the material.

Typical mistakes when replacing the cabin filter

Even such a simple procedure as replacing a filter can go wrong if some nuances are not taken into account. Here are the most common mistakes:

• 🔄 Wrong filter direction. If you put it upside down, the filtration efficiency will drop by 30-40%, and dust will penetrate into the cabin. Always follow the arrows!
• 🔩 Loss of screws or latches. When disassembling the glove compartment, it is easy to drop small parts. Store them in a separate box.
• 🧹 Ignoring case cleaning. If you do not remove dust and debris from the compartment, the new filter will clog twice as quickly.
• 🔧 Use of force. The plastic latches of the glove compartment are fragile - if they do not give in, it is better to double-check that all the latches are pressed out.

Another common problem is purchasing a non-original filter of the wrong size. For example, filters from Renault Duster They are similar in appearance, but may not be suitable in height. Always check the article number or take the filter with you to the store for fitting.

⚠️ Attention: If, after replacing the filter, a burning or plastic smell appears in the cabin, immediately turn off the fan and check whether a foreign object (for example, a filter wrapper) has entered the air duct. Prolonged operation of the fan with blocking can lead to overheating of the motor.

What happens if you don't change the cabin filter?

Many owners Nissan Terrano They neglect to replace the filter, considering it a “trifle”. However, the consequences can be serious:

Problem	Reason	Consequences
Fogging of windows	Poor air circulation due to clogged filter	Reduced visibility, risk of accidents
Unpleasant smell	Reproduction of bacteria and mold in a wet filter	Allergies, headaches, nausea
Weak airflow	Increased fan load	Blown fuse or fan motor (repair from RUB 5,000)
Air conditioner breakdown	Dust and debris enter the evaporator	Freon leak, expensive repairs (from RUB 15,000)

Owners of the 2019 Terrano share on forums that when driving more than 30,000 km without replacing the filter, they had problems with the climate control electronics - the sensors began to give false readings due to the accumulation of moisture in the system.

In addition, a dirty filter can cause "sick building syndrome" — when the concentration of CO₂ and harmful substances in the cabin exceeds the norm, causing drowsiness and decreased driver response. This is especially dangerous on long trips.

Tips for caring for the cabin filter and ventilation system

To ensure that the filter lasts longer and the air in the cabin remains fresh, follow these recommendations:

• 🌿 Ventilate the interior after trips, especially in rainy weather. Humidity accelerates mold growth.
• 🚗 Use recycling in traffic jams or dusty conditions to reduce strain on the filter.
• 🧴 Treat your air conditioning system antibacterial sprays (eg Step Up or Wynn's) once every six months.
• 🔧 Check the drainage hole under the glove compartment - if it is clogged, water will accumulate in the cabin, creating an ideal environment for bacteria.

If you often drive off-road, you can install prefilter (for example, from K&N) - it traps large dust particles, prolonging the life of the main filter. It is also useful to clean the ventilation deflectors with compressed air (using a keyboard cleaning can) once every 3 months.
