Many owners Kashkaya they are afraid to take on the replacement themselves for fear of breaking the plastic latches or installing the new filter incorrectly. In fact, the procedure takes no more than 15 minutes and does not require special tools - just know a few nuances. In this article you will find step-by-step instructions with photos, article numbers of original and analogue filters, as well as answers to frequently asked questions. We will also look at what replacement errors lead to squeaks in the cabin or incorrect operation of the climate control.

When to change the cabin filter Nissan Qashqai 2018?

Official regulations Nissan requires replacing the cabin filter every 15,000 km or once a year. However, these figures are relevant for ideal operating conditions - clean air, moderate humidity and the absence of dusty roads. In the realities of Russian cities and highways, the filter can clog 2–3 times faster.

There are several signs that indicate the need for replacement ahead of the regulations:

• 🚗 Reduced furnace/air conditioner efficiency: The air blows weaker, even at maximum fan speed.
• 🌫️ Constant smell of dust or mold in the cabin, especially when the airflow is turned on.
• 💨 Fogging of windows for no apparent reason (even in dry weather).
• 🤧 Allergic reactions Passengers: sneezing, itchy nose, watery eyes.
• 🔍 Visible dirt on the surface of the filter (if you have already taken it out).

If you often drive on dirt roads, live in a metropolis or near industrial areas, it is better to reduce the replacement interval to 8–10 thousand km. It is also worth checking the filter after long trips in rainy weather - moisture can cause mold to develop.

Which cabin filter to choose: original or analogue?

For Nissan Qashqai J11 In 2018, two types of filters are suitable: ordinary dust (barrier) and coal (with activated carbon). The latter cope better with odors and toxic gases, but are more expensive. Original articles:

Filter type	Article Nissan	Approximate price (RUB)	Analogs (brand + article)
Dust (regular)	27277-JD00A	1 200–1 500	Mann CU29003, Bosch 1987432464, Filtron K1321
Coal	27277-JD00B	1 800–2 200	Mann CUK29003, Bosch 1987432465, Filtron K1321A
Coal (high capacity)	27277-4M00A	2 500–3 000	Mahle LAK939, Denso DCF305P

Among analogues, filters are especially popular Mann And Bosch - they are not inferior to the original in quality, but are 20-30% cheaper. If you choose a carbon filter, pay attention to coal layer density: with cheap analogues it is often thinner than stated. Also check air flow direction (indicated by an arrow on the body) - incorrect installation will reduce the filtration efficiency by 50%.

⚠️ Attention: Do not buy filters without packaging or with damaged film. Even a new filter can become contaminated with mold if stored in a damp area.

Where is the cabin filter located? Nissan Qashqai 2018?

B Qashqai J11 2018 cabin filter located behind the glove compartment on the passenger side. To get to it, you don’t need to disassemble the dashboard or remove the trim—just fold back the glove compartment and remove the protective cover. This is a typical solution for most crossovers Nissan/Renault, so if you previously changed the filter to X-Trail or Duster, the process will be similar.

Exact location:

1. Open the glove compartment (glove box) and empty it of its contents.
2. Click on two latches on the sides (they are located inside the glove compartment, closer to the cabin).
3. Lower the glove compartment down and it will lock in a vertical position.
4. Behind the glove compartment you will see plastic cover with the inscription Air Filter or an arrow.

On some versions Qashqai (for example, with climate control Auto A/C) the cover can be attached to additional screw - It can be easily unscrewed with a Phillips screwdriver. Don't be alarmed if you see a layer of dust or leaves on the filter - this is normal for a machine that has been in use for more than a year.

What to do if the glove compartment won't go down?

If the latches do not engage, check to see if they are jammed due to debris. Carefully pry the glove compartment open with a flathead screwdriver (wrapping it in a cloth to avoid scratching the plastic) and pull down. Do not use excessive force - the plastic will not Qashqai fragile!

Step-by-step instructions for replacing the cabin filter

To replace you will need:

• 🔧 Phillips screwdriver (if the cover is self-tapping).
• 🧹 Vacuum cleaner or brush for cleaning the case.
• 📦 New filter (check the article before purchasing!).
• 🧴 Wet wipes or rag.

Step 1. Preparation

Park the car on a level surface and turn off the engine. Open all doors for 5-10 minutes to ventilate the interior - this will reduce the amount of dust that gets into your face when removing the filter. If it's cold outside, you can turn on the stove at maximum temperature for 2-3 minutes - this will soften the plastic latches.

Step 2. Removing the glove compartment

Press the latches inside the glove compartment (they are located on the side walls, closer to the interior) and lower it down. If the glove compartment is tight, check whether the fuse box is in the way (on some versions it is located next to it).

Step 3: Removing the filter cover

If the cover is secured with latches, pull it towards you. If it is on a self-tapping screw, unscrew it with a Phillips screwdriver. Be careful: the plastic is fragile and the latches can break if you force them too hard.

Step 4: Removing the Old Filter

Carefully remove the filter by pulling it down. Please note arrow direction (it indicates air flow). If the filter falls apart in your hands or mold is visible on it, before installing a new one, treat the filter housing with an antiseptic (for example, Liqui Moly Klima-Anlagen-Reiniger).

Step 5: Install a new filter

Check whether the direction of the arrow on the new filter matches the direction on the old one. Insert the filter into the grooves until it clicks. It should fit tightly, without gaps.

Step 6. Assembly

Replace the cover, latch it and return the glove compartment to its original position. Check for squeaks when opening/closing the glove compartment - if they appear, it means the filter is installed incorrectly or the lid is not secured.

⚠️ Attention: If, after replacement, a whistle or creaking appears in the cabin when the stove is operating, check whether the filter housing is bent. This is a common problem when installing non-original filters with a thick carbon layer.

Common replacement mistakes and how to avoid them

Even something as simple as replacing the cabin filter can turn into problems if you make one of these mistakes:

• 🔄 Wrong filter direction. The arrow on the body should point down (in the direction of air movement). If you mix it up, the filter will not clean, but trap dust at the outlet, impairing the operation of the stove.
• 🧩 Loose installation. If the filter is not completely seated in the grooves, unfiltered air will pass through the gaps. Check for gaps around the edges.
• 🔧 Damage to glove compartment latches. Many people break them trying to open the glove compartment by force. If the latch is broken, it can be replaced (article no. 80510-JD00A).
• 💨 Ignoring case cleaning. Dust and leaves that have accumulated in the housing can clog the new filter within a few weeks. Always clean the housing with a vacuum cleaner before installation.
• 🚫 Buying a filter without a carbon layer for the city. In a metropolitan area, a carbon filter pays for itself in 2–3 months due to better protection against smog and exhaust gases.

Another typical problem is squeak after replacement. It occurs if:

• The filter is too thick (especially with cheap analogues) and touches the lid.
• The filter cover is not latched completely.
• Debris (sand, leaves) got into the grooves.

To eliminate squeaking, remove the filter, clean the grooves and reinstall it, making sure it is not deformed.

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

Many owners Qashqai They neglect to replace the filter, considering it a “minor” consumable. However, the consequences can be serious:

• 🦠 Proliferation of bacteria and mold. A wet filter is an ideal environment for fungi. Their spores can cause allergies and even bronchitis.
• 🔥 Overheating of the stove. A clogged filter increases the load on the fan, which leads to its premature wear (the cost of replacing a fan is from 15,000 rubles).
• 🌡️ Air conditioner performance deterioration. If the filter does not allow air to pass through, the air conditioning compressor runs idle, which leads to its breakdown.
• 🚗 Fogging of windows. Poor air circulation disrupts the operation of the ventilation system, and the windows fog up even in dry weather.
• 💰 Increased fuel consumption. When the filter is clogged, the climate control system spends more energy on heating/cooling, which increases the load on the engine.

In extreme cases, ignoring filter replacement can lead to failure of the air conditioner evaporator (replacement cost starts from RUB 30,000) or the climate control unit. For example, in service centers Nissan often found Qashqai with an error P0500 (malfunction of the air speed sensor), caused precisely by a clogged filter.

If you decide to save money and buy a non-original filter, after installation, turn on the stove at maximum power and check for any foreign odors. Cheap filters sometimes have a chemical smell that disappears after 1-2 days.

Frequently asked questions about replacing the cabin filter with Nissan Qashqai 2018

Is it possible to drive without a cabin filter?

Technically yes, but this will lead to rapid contamination of the air conditioner evaporator and ventilation ducts. Without a filter, dust and leaves will fall directly into the cabin, and the stove and air conditioner will lose up to 30% efficiency. In the long run, this will result in costly repairs.

Which filter is better: carbon or regular?

A carbon filter is better at removing odors and toxic gases (such as those from traffic jams), but they are more expensive and can clog faster. If you live in a city or near an industrial area, a carbon filter will pay for itself. For rural areas, an ordinary dust one is sufficient.

How much does it cost to replace a filter at a service center?

At official dealerships Nissan Replacing a cabin filter costs from 800 to 1,500 rubles (excluding the cost of the filter). In independent services the price is lower - 500–800 rubles. However, the procedure is so simple that there is no point in overpaying.

Is it possible to wash the cabin filter instead of replacing it?

No. The filter consists of a fibrous material that loses its properties after washing. In addition, bacteria accumulate in it, which cannot be completely washed out. The only exception is professional steam cleaning, but it will cost more than a new filter.

Why does the stove blow weaker after replacing the filter?

This can be caused by several reasons:

1. Filter installed wrong side (the arrow is mixed up).
2. Filter cover not tightly closed, and the air passes by.
3. New filter too tight (especially with cheap coal analogues).
4. Crowded air ducts (professional cleaning required).

Check the filter installation and, if necessary, return the old one to compare the air flow.
