Step-by-step instructions: how to replace the cabin filter in Nissan Pulsar FN15 with your own hands

Replacing the cabin filter in Pulsar FN15 - one of the simplest procedures that even a beginner can handle. All you need:

• 🔧 New filter (suitable in size and type).
• 🔦 Flashlight (for a better view).
• 🧹 Vacuum cleaner or damp cloth (to clean the case).
• 🧤 Gloves (optional, so as not to get your hands dirty).

The filter is located behind the glove compartment, so no tools are required for parsing. Follow the instructions:

1. Open the glove compartment and release him completely from the content. To access the filter, you must remove the restrictors.

2. On both sides of the glove compartment there is plastic clips (one on each side). Gently squeeze them and pull the glove compartment towards you - it will come out of the grooves and go down.

3. Behind the glove compartment you will see plastic cover filter. It is secured with two latches. Squeeze them out and remove the lid.

4. Pull old filter by the special handle (if there is one) or carefully pry it from the side. Be careful - there may be a lot of dust inside!

5. Clear filter housing remove dirt with a vacuum cleaner or damp cloth. For severe contamination, you can use an antibacterial spray.

6. Install new filter, observing the direction of the arrow (usually it is indicated on the body - ↑ UP or → AIR FLOW).

7. Close the lid, return the glove compartment to its place and snap the latches into place.

The whole process takes no more than 10–15 minutes. If this is your first time doing this, we recommend watching video instructions (for example, on YouTube by request "Nissan Pulsar FN15 cabin filter replacement") to visually see the location of the latches.

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

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

1) Correct direction (the arrow should point upward or along the air).

2) Compliance with size (sometimes analogues may differ slightly in size).

3) The presence of foreign objects in the housing (for example, remnants of an old filter).

If the problem persists, try bending the edges of the filter slightly (but do not overdo it to avoid damage!).

Common mistakes when replacing the cabin filter and how to avoid them

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 owners make Nissan Pulsar FN15:

⚠️ Attention! Never install a filter without observing air direction (arrow on the body). This will lead to the fact that dust will not linger, but will penetrate into the cabin, and the filter itself will quickly become clogged.

1. Ignoring cleaning the case. Many people simply install a new filter without removing dirt and dust from the housing. This will shorten the life of the new filter and may cause an unpleasant odor.

2. Buying the wrong size filter. Even if the article number is the same, sometimes analogues may differ in size by several millimeters. Always check the dimensions with the old filter.

3. Strong compression or deformation of the filter during installation. This leads to disruption of the structure of the filter material and a decrease in cleaning efficiency.

4. They forget to latch the glove compartment. If the latches are not fully latched, the glove compartment will hang loose or may fall out during heavy braking.

5. Use of used filters. Some people try to “revive” an old filter by soaking it in fragrances or rinsing it with water. This is not only useless, but also dangerous - a wet filter can become a source of mold.

How to extend the life of a cabin filter: care tips

The cabin filter is a consumable, but its service life can be increased if you follow simple recommendations:

• 🚗 Ventilate the interior regularly. After driving in rainy weather or high humidity, leave the windows slightly open for 5-10 minutes to avoid condensation.
• 🌿 Use fragrances with an antibacterial effect. They will not replace the filter, but will help reduce the risk of bacterial growth.
• 🔄 Periodically turn on the air conditioner at maximum power. This helps dry out the system and prevent mold.
• 🚫 Avoid parking under trees with pollen in bloom. If this is unavoidable, close the windows and recirculate the air.
• 🧼 Clean ventilation deflectors. Dust on them can get into the cabin, even if the filter is new.

If you often drive on dusty roads, you can install prefilter (mesh) in front of the main filter. It will trap large particles and extend the life of the main filter element.

It is also worth paying attention to antifreeze quality in the heating system. If it is old or diluted, this can lead to corrosion of the stove radiator, which in turn impairs the performance of the ventilation system and shortens the service life of the filter.

Frequently asked questions about the cabin filter Nissan Pulsar FN15

Is it possible to drive without a cabin filter?

Technically yes, but it is highly discouraged. Without a filter, not only dust will enter the cabin, but also harmful gases (for example, from the exhaust of other cars), as well as pollen, which can cause allergies. In addition, dirt will settle on the stove radiator, which will lead to its clogging and reduced heating efficiency.

Which filter is better - carbon or regular?

A carbon filter is preferable, especially if you live in a city or are often stuck in traffic jams. It not only traps dust, but also neutralizes harmful gases (for example, nitrogen oxides) and unpleasant odors. A regular filter is cheaper, but it is only enough to protect against large particles.

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

At official dealerships Nissan for filter replacement they charge from 800 to 1,500 rubles (excluding the cost of the filter itself). In independent services the price is usually lower - 300–600 rubles. However, the procedure is so simple that there is no point in overpaying.

Is it possible to wash the cabin filter?

No, the filter cannot be washed. Water destroys its structure, and after drying it loses its filtering properties. In addition, a wet filter can become a source of mold. If the filter is very dirty, it only needs to be replaced.

Why does the stove blow weaker after replacing the filter?

This may be due to several reasons:

1. The filter is installed incorrectly (for example, on the wrong side).
2. The filter cover is not tightly closed, and air is sucked in from the side.
3. The heater radiator or air ducts are clogged (diagnostics required).
4. The new filter is too dense (for example, carbon after the usual one).

Check for correct installation and contact service if necessary.
