Many owners mistakenly believe that this part lasts forever or does not affect ride comfort at all, which is completely wrong.

Timely replacement air purification filter directly affects the health of passengers and the performance of the ventilation system. A clogged element stops trapping dust, pollen and exhaust gases, allowing them to pass directly into the cabin, which is especially critical in city traffic. In addition, a decrease in throughput leads to fogging of the windows and overload of the heater fan.

Access to the cleaning element does not require dismantling the entire instrument panel.

It is enough to open the glove compartment and unclip the special limiters.

The replacement procedure takes no more than fifteen minutes, even for a beginner.

However, it is important to be careful not to break the plastic clips.

It is important to understand that filter housing in this model it is made of fragile plastic, which over time becomes brittle from temperature changes and exposure to ultraviolet radiation. When trying to remove the old element or insert a new one, excessive force can lead to a crack in the housing, which will lead to the suction of untreated air past the filter.

Some trim levels include carbon filter, which works more efficiently than usual.

A regular paper element only traps large particles of dust and insects.

The coal layer is capable of adsorbing odors and harmful gases from the atmosphere.

The choice of type depends on your priorities and vehicle operating conditions.

⚠️ Warning: Never try to remove the filter by force if it is stuck. Check that the cover latches are fully released, otherwise you risk breaking the air intake housing, the repair of which will cost much more than the part itself.

The aftermarket offers a huge variety of options for Nissan Almera G15. Official original catalog number Nissan filter - 27277-1KC0A. This element is distinguished by a high quality of fit and a stable degree of purification, but its cost may be inflated compared to analogues. Often in the box with the original there is a filter produced by the world's major partner brands of the automaker.

When choosing a non-original part, it is important to pay attention to the density of the material.

Cheap analogues often have a too loose structure, allowing fine dust to pass through.

A high-quality filter must have a rigid frame that prevents deformation.

The sealing rubber should be soft and elastic and fit snugly to the body.

Among the popular manufacturers, there are several reliable brands that have proven themselves in the spare parts market for Nissan.

• 🌿 Mann-Filter - German quality, excellent filtration, but high price.
• 🇯🇵 Denso - a Japanese brand, often supplied as an original to the assembly line.
• 🇰🇷 Sakura - a popular budget option with a good price/quality ratio.
• 🇷🇺 GoodWill - domestic manufacturer, affordable, but quality varies from batch to batch.

You should not chase the lowest price, as saving on the health of passengers can result in problems.

When ordering online, always check the part number with the instruction manual.

Sometimes the same part may have different numbers depending on the year of manufacture.

It is best to buy filters in specialized stores or from authorized dealers.

Coal or regular: what is the difference and which is better?

The main difference between filter types is the filter element material. Regular filter consists of compressed paper or synthetic fibers impregnated with an antibacterial composition. Its main task is the mechanical retention of large particles: dust, sand, leaves and insects. This is the basic option, which is installed at the factory in basic configurations.

The carbon filter has an additional layer of activated carbon between layers of paper.

This layer acts as an adsorbent, attracting molecules of gases and odors.

Coal effectively traps nitrogen oxides, sulfur oxides and vehicle exhaust gases.

For urban use, this option is much better suited than usual.

However, carbon filters have one significant disadvantage - they create greater aerodynamic drag.

This may slightly reduce the performance of the furnace fan and air conditioner.

If heavily soiled, a carbon filter requires more frequent replacement than a paper filter.

Ignoring this fact may lead to overheating of the heater motor.

⚠️ Warning: If you live in a region with very dusty roads or in a highly dusty area (mining towns, deserts), the carbon filter may clog faster. In such extreme conditions, sometimes it makes more sense to use a high-quality paper filter and change it more often.

For Nissan Almera G15, which is often operated in dense city traffic, The carbon filter is the most balanced choice for maintaining clean air in the cabin and protecting the health of passengers from exhaust gases. This is especially true if you often sit in traffic jams or drive outside the city on the highway next to trucks.

Many owners note that after installing a carbon filter, the burning smell from neighboring cars disappears.

The perception of aromas also improves if you use fragrances.

The humidity inside the cabin is stabilized when using high-quality coal.

The conclusion is clear: overpaying for a carbon filter pays off in comfort.

Step-by-step instructions for replacing the filter yourself

Replacement cabin filter on Almera G15 - a procedure available to every car owner with minimal skills in handling tools. You don't need a complex set of keys or specialized equipment. All you need is a new part and a little time. The whole process takes about 10-15 minutes.

Before starting work, open the hood and let the engine cool down if the car has been moving.

Open the front passenger door and make sure there is nothing blocking access.

Clear the glove box of excess items so that they do not fall out during dismantling.

Bring a flashlight, as the area under the panel may be dark.

First you need to unclip the glove box latches.

They are located on the sides inside the box and are plastic stops.

Gently press them with your fingers, releasing the side walls.

Lower the box all the way down, but do not tear it so as not to break the cable or hinges.

Behind the glove compartment you will see a plastic cover with the words "AIR FILTER" or a fan symbol on it.

Open the lid by unlatching the latches around the perimeter (usually there are two or three).

Remove the old filter, noting the airflow direction (air flow arrow).

Clean the seat from dust and debris using a vacuum cleaner or cloth.

Insert the new filter, observing the correct direction of the arrow.

The arrow should point downwards or in the direction corresponding to the air flow.

Press the lid until the latches click.

Return the glove box to its original position by snapping the side supports into place.

⚠️ Attention: If you insert the filter backwards, the arrow will not point towards the air flow, but vice versa. This will cause the filter to start working like a pump, becoming clogged with dust in a matter of days, and the air flow into the cabin will practically stop.

Common mistakes when replacing

Some owners forget to clean the housing of dirt, which causes the new filter to immediately become dirty. Others break the lid latches using excessive force, or forget about the air flow direction arrow, which reduces the filtration efficiency to zero.

After installation, be sure to check the operation of the ventilation system.

Turn the heater on to maximum power and make sure there is air flow.

Listen for any extraneous noise or whistling from the deflectors.

If the sound changes, the filter may be installed crookedly or the lid may not be fully closed.

Symptoms of contamination and replacement intervals

Determine what cabin filter requires replacement, based on a number of indirect signs. The most obvious symptom is a decrease in the intensity of air flow from the deflectors when the fan is on. If you set the maximum blowing speed and the air is blowing weakly, it means the filter is clogged with dust and debris.

The second sign is the appearance of an unpleasant odor, especially when the air conditioner is turned on.

The smell may be musty, dusty, or even chemical if the filter is saturated with dirt.

The glass begins to fog up faster and is more difficult to clean.

Dust may appear in the cabin and settle on the dashboard and windows.

The recommended replacement frequency is once a year or every 15-20 thousand kilometers.

If you operate the car in dusty conditions, the interval should be reduced to 10 thousand.

When driving around the city during the flowering season, replacement may be required more often.

It is better to change the filter preventively, without waiting for obvious symptoms of contamination.

• 🌫️ Reduced airflow - the main indicator of clogging.
• 👃 Unpleasant smell - a sign of bacterial growth in the filter.
• 💧 Fogging of windows - the result of a violation of air circulation.
• 🦠 Allergic reactions — dust and allergens penetrate into the cabin.

Ignoring these symptoms may result in heater motor failure.

Overloading the fan due to high air resistance reduces its service life.

Moisture remaining in a dirty filter can cause corrosion of stove parts.

Regular replacement is a cheap way to extend the life of your air conditioning system.

Common mistakes and myths about cabin filters

Around the topic cabin filters There are many misconceptions that can harm your car. One of the most popular myths is that the filter can be washed and reused. This is absolutely false. The materials from which it is made cannot be restored after contamination, and washing only destroys the structure of the fibers and destroys the antibacterial coating.

Another myth is that the filter is only needed for the air conditioner.

In fact, it works both when the stove is running and during normal ventilation.

Some owners believe that they can install a filter from another Nissan model.

This is dangerous, as the dimensions may differ and gaps will appear for dust to leak in.

It is also a mistake to believe that an expensive filter lasts forever.

Any filter has its own resource, which depends on operating conditions.

The carbon filter loses its adsorption properties over time.

Even an original part requires timely replacement.

⚠️ Attention: Never use homemade filters made of gauze, cotton wool or foam rubber. Not only will they not clean the air, but they can also block the flow, causing the heater motor to overheat or debris to enter the air conditioner evaporator.

Sometimes owners try to “save money” by installing a filter once for several years.

This leads to a huge amount of harmful substances entering the cabin.

The health of children and passengers is not worth such dubious savings.

The cost of a quality filter is not comparable to the cost of allergy treatment.

It is important to understand that the filter is a consumable item, like oil or pads.

Its replacement should be part of regular vehicle maintenance.

Don't wait until the filter turns into a piece of dirt.

Timely replacement guarantees clean air and a comfortable ride.

Questions and answers (FAQ)

How much does it cost to replace the cabin air filter at the dealer?

At dealers, the cost of replacement work usually ranges from 800 to 1,500 rubles, plus the price of the original filter itself, which can reach 2,000 rubles. In independent services, the work is cheaper, but it is better to do it yourself, since the procedure is extremely simple.

Is it possible to drive without a cabin filter in the Nissan Almera G15?

Technically, the car will work, but dust, dirt and insects will begin to enter the interior. This will lead to rapid contamination of the air conditioner evaporator, the appearance of mold and unpleasant odors. The load on the stove fan will also increase. Driving without a filter is not recommended.

Why does the new filter make a whistle when the stove is turned on?

Whistling may occur due to improper installation: the filter may be wrinkled or pinched, blocking part of the flow. Also, the reason may be that the housing lid is not completely closed, and air passes through the cracks with turbulence. Check the installation for tightness.

How do you know which side to insert the filter into?

There is always an arrow on the filter housing that says "AIR FLOW" or "UP". The arrow should indicate the direction of air movement. In the Almera G15, air usually moves from top to bottom or towards the cabin, so the arrow should point down or inside the body. If there is no arrow, focus on the side with a denser mesh or frame.

Can I use a filter from a Nissan Note or Tiida?

Filters from different models may have similar sizes, but do not always fit perfectly. The Nissan Almera G15 uses a specific body size and shape. Using a filter from a different model may result in it not fitting into the grooves or causing it to dangle, allowing untreated air to pass through. Always use a filter designed specifically for your model.
