The effective operation of the ventilation and air conditioning system in a car directly depends on the condition of the cleaning element located in the engine compartment. For owners Nissan Qashqai For the 2019 model year, this issue is especially acute, since it was during this period that models began to be equipped with modern climate control systems that require an uninterrupted flow of clean air.
Ignoring the timing of replacement leads not only to fogging of the windows in rainy weather, but also to serious problems with the air conditioning compressor. When cabin filter becomes clogged with dust and dirt, the fan has to work with increased load, which can ultimately result in its burnout or failure of the entire cooling system.
Many car owners mistakenly believe that replacing this consumable is a complex procedure that requires specialized tools and a lift. In fact, if you know the exact location of the body and the sequence of actions, the whole process takes no more than fifteen minutes, even for a person who has opened the hood of his car for the first time. Nissan.
Why replacing the filter element is critical for Nissan Qashqai
In a city with heavy traffic, a huge amount of air containing dust, soot from exhaust gases and allergens passes through the car ventilation system every hour. If you are using carbon filter, it is capable of trapping not only mechanical particles, but also unpleasant odors, which is especially important when driving behind trucks in traffic jams.
A clogged element creates resistance to air flow, causing the windshield to become weak. In winter, this becomes a critical problem, since you will not be able to quickly remove ice, and in summer, the air conditioner stops coping with the heat, producing warm air even at the minimum temperature.
Additionally, the moist environment inside an old filter becomes an ideal breeding ground for bacteria and mold. This is why you can feel a specific musty smell when you turn on the ventilation, even if the interior is visually clean. Replacing the filter — this is not just technical maintenance, it is concern for the health of passengers.
Choosing the right consumables: original or analogue
When purchasing a new part, it is important to pay attention to the markings, since Nissan Qashqai For 2019, different types of elements are suitable depending on the configuration and the presence of a climate control system. The original article often has a number 27277-1HC0A or 27277-3HM0A, but the market offers many quality substitutes.
It is worth considering options from trusted brands such as Corteco, Mann-Filter or Sakura. These manufacturers use denser materials and improved activated carbon technology, which sometimes produces results even better than the original. However, it is important to ensure that the replacement you choose has the correct shape and thickness to fit snugly into the case.
There are also budget options that can cost three times less, but their effectiveness is often questioned. Thin paper in cheap filters quickly gets wet and does not retain small particles, allowing dirt to pass directly into the cabin. Saving on such little things can lead to expensive repairs to the ventilation system in the future.
The table below compares popular options for your vehicle:
| Brand | Filter type | Approximate price | Features |
|---|---|---|---|
| Nissan (Original) | Coal | 2500–3500 rub. | Ideal geometry, guaranteed quality |
| Mann-Filter | Coal | 1200–1800 rub. | High cleaning efficiency, durability |
| Corteco | Coal | 900–1400 rub. | Excellent value for money |
| Sakura | Regular/Coal | 600–1000 rub. | Budget option, average resource |
⚠️ Attention: Make sure that you buy a carbon filter if your package includes an activated carbon block. A regular paper filter will not trap exhaust odors.

Preparation for replacement and necessary tools
Before starting work, you will need a minimum set of tools that every motorist has. In most cases, only one Phillips-head screwdriver is sufficient PZ2 and perhaps a flashlight to illuminate hard-to-reach places.
If you plan to change the filter in winter or during the cold season, the plastic latches may become brittle, so it is recommended to warm up the car beforehand or work in a warm box. It is also worth preparing a place to install the removed old element so as not to spread dirt over the hood.
It is important to check that the new filter has a protective film on one or both sides. This film must be carefully removed before installation, otherwise it will block the air flow and create a muffler effect. Never try to install a filter with film - this is a serious mistake.
Sometimes, to access the body, it may be necessary to remove the plastic trim on the hood if it interferes with free access to the mounting bolts. This is easy to do; simply unscrew the latches by hand or using a flat-head screwdriver.
☑️ Preparation for replacement
Step-by-step instructions for replacing the filter on Qashqai 2019
Open the car hood and secure it in the up position using the gas shock absorber. Locate the cabin air filter housing, which is located on the passenger side, just behind the radiator grille and plastic housing.
Inspect the housing cover. It is attached to several screws, which can be hidden under decorative plugs. Carefully unscrew all fasteners and put them in a safe place so as not to lose them.
Remove the housing cover. Be careful as leaves or small debris may accumulate underneath and fall inside when unscrewed. If you see accumulated dirt, carefully remove it with a dry cloth.
Remove the old filter. Pay attention to the direction of air flow, which is indicated by the arrow on the filter housing. This is critical for proper installation of the new element.
Clean the internal cavity of the housing from any remaining dust and leaves. Use a vacuum cleaner or compressed air to thoroughly vacuum the niche. This will ensure the installation of the new filter is tight.
Insert the new filter into the housing, strictly observing the direction of the air flow arrow. Make sure the filter fits tightly and is not distorted.
Replace the cover and tighten all screws. Check that the lid sits smoothly and has no gaps.
Common mistakes when replacing
Car owners often forget about the direction of the arrow, which is why the filter operates in a “counterflow” mode, quickly becomes clogged and destroyed. You should also be careful with fragile plastic latches on older cars, which can crack if the cover is removed carelessly.
Before installing a new filter, wipe its sponge with a damp cloth to remove factory dust that may enter the cabin when the ventilation is first turned on.
Typical problems and operating nuances
Some owners Nissan Qashqai They are faced with the fact that after replacing the filter, the fan noise does not decrease or even increases. This may be due to the fact that during the dismantling process, foreign dust or debris entered the housing, which now interferes with the impeller.
It is also worth considering that if the old filter was very dirty, it could become deformed and fit tightly to the walls of the housing. A new, denser filter may require time to “unroll”, so the effect of maximum cleaning will not appear immediately.
In rare cases, there is a problem with mismatched geometry of cheap analogs. If the filter is loose or does not go in all the way, do not try to force it in. This will cause the seal to rupture and untreated air to leak past the filter.
⚠️ Attention: If you hear a strange whistling or noise after replacing the filter, stop immediately and check that it is installed correctly. An incorrectly installed element may block the air intake and cause overheating of the fan motor.
Correct installation of the filter along the air flow arrow is the key to a long life of the ventilation system and the absence of extraneous noise.
Maintenance regulations and manufacturers' recommendations
Official Maintenance Schedule Nissan recommends changing the cabin filter every 15,000 kilometers or once a year, whichever comes first. However, in real urban conditions, it is better to reduce this interval to 7,000–10,000 kilometers.
If you often travel on dusty roads, in rural areas or in a metropolis with a high concentration of exhaust gases, check the condition of the filter every 5,000 kilometers. A visual inspection will show the degree of contamination and the need for unscheduled replacement.
It is also worth paying attention to seasonal features. In the fall, when the leaves begin to actively fall off, the filter may clog faster due to leaves getting into the ventilation system. In the spring, when the heating is turned on, moisture accumulated over the winter can become a source of unpleasant odor.
How to check the filter without replacing
If you are not sure whether to replace it, you can carefully remove the filter and look at it against the light. If you see gaps and light passes through the material, the filter may still serve. If the light does not pass through, replacement is required.
Impact on driving comfort and safety
The quality of air in the cabin directly affects driver fatigue. A dirty filter reduces oxygen levels and allows carbon dioxide to accumulate, which can lead to drowsiness while driving. Clean air keeps you alert and alert.
In addition, a properly functioning ventilation system ensures that the windows quickly fog up. In rainy weather, this is critical for safety, since a clean windshield is the key to a good view and the absence of accidents.
Do not forget that replacing the filter is one of the simplest and cheapest procedures, which significantly increases the operating comfort of your car. Do not put off this task until later, especially if you feel changes in the operation of the climate system.
Regular filter replacement is an investment in safety and comfort, which pays off in the absence of problems with visibility and health of passengers.
