Cabin filter <em>Nissan Note E12</em>: where is it located and how to replace it yourself

Why a cabin filter? Nissan Note E12 requires attention?

Cabin filter in Nissan Note E12 (2012–2020) is not just a consumable, but a key element of comfort and safety. It protects you from dust, pollen, exhaust fumes and even bacteria that enter the cabin through the ventilation system. In urban operation conditions, the filter clogs 2–3 times faster than prescribed by regulations, and ignoring it leads to deterioration in stove performance, the appearance of unpleasant odors and increased dustiness in the air.

The manufacturer recommends changing the cabin filter every 15,000 km or once a year, but the actual period depends on operating conditions. For example, if you often drive on dirt roads or sit in traffic jams near industrial areas, the filter may become unusable within 8–10 thousand km. In this article we will show you where exactly the cabin filter is located in Nissan Note E12, how to replace it without a service station, and what signs indicate the need for urgent replacement.

Where is the cabin filter located? Nissan Note E12?

Unlike many cars, where the filter is hidden behind the glove compartment or under the hood, in Nissan Note E12 it is located under the dashboard on the passenger side. More precisely, in the niche under the glove box (glove compartment), but access to it opens only after removing the decorative cover. This is a typical solution for the platform Nissan B, on which it is built Note E12.

To get to the filter, you do not need to disassemble half of the cabin or use a special tool. Enough:

• 🔧 Open the glove compartment and empty it of its contents.
• 🔍 Find the plastic hatch cover under the glove compartment (it is attached with two latches).
• 🖐️ Press the latches and pull the lid towards you - the filter will be right behind it.

Important: in some modifications Nissan Note E12 (for example, with climate control) the cover can be secured with a screw using a Phillips screwdriver. Check this in advance to avoid breaking the latches.

Even if you don’t remember the last time you changed the filter, the interior itself will tell you about the problem. Here 5 Key Symptoms, which indicate the need for replacement:

• 🌬️ Weak air flow from the deflectors when the ventilation is turned on (even at maximum speed).
• 🤧 Constant smell of dampness or mold in the cabin, especially after rain.

Important! B Nissan Note E12 two types of filters are installed:

• 🔄 Regular dust (For example, Mann CU 22003 or Bosch 1 987 429 655).
• 🦠 Coal (with an additional layer of activated carbon to neutralize odors, e.g. TSN 9.7.868).

If you often drive in traffic jams or on dusty roads, it is better to choose a carbon filter - it keeps the air in the cabin fresh for longer.

What happens if the filter is installed incorrectly?

If the filter is installed with the arrow pointing down or sideways, it will not effectively capture dust, and the air flow may deform the material. In the worst case, the filter will fold like an accordion and block the access of air to the cabin, which will lead to overheating of the stove or air conditioner.

Which cabin filter to choose for Nissan Note E12?

There are dozens of filter options on the market for Nissan Note E12, but not all of them are equally effective. We tested several popular models and compiled price/quality ratio rating:

Brand and article	Type	Service life	Price (approximate)	Features
Mann CU 22003	Dusty	10–15 thousand km	400–500 ₽	High quality filtration, suitable for allergy sufferers
Bosch 1 987 429 655	Dusty	12–15 thousand km	350–450 ₽	Good throughput, does not impair the operation of the stove
TSN 9.7.868	Coal	8–10 thousand km	600–750 ₽	Neutralizes odors perfectly, but clogs faster
Sakura CAC-2851	Coal	10–12 thousand km	500–600 ₽	Japanese quality, durable carbon layer
Nissan 27277-4M000	Original (dust)	15 thousand km	1 200–1 500 ₽	Guaranteed compatibility, but overpay for the brand

If you live in a region with high humidity (for example, St. Petersburg, Sochi), give preference to carbon filters - they prevent the appearance of mold in the ventilation system. For dry climates (for example, Moscow, Kazan), a high-quality dust filter is sufficient.

Common mistakes when replacing the cabin filter in Nissan Note E12

Even such a simple procedure as replacing a filter can be ruined by errors. That's what can't do:

⚠️ Attention! Never try to wash out an old cabin filter with water or a vacuum cleaner. Moisture deforms the fibers, and the vacuum cleaner does not remove germs and allergens. Such a “cleaned” filter will become a breeding ground for bacteria.

• 🔨 Use force when removing the cover. The plastic latches are fragile - if they break, you will have to buy a new cover (and it often only comes complete with the air duct).
• 🔄 Install the filter without the arrow or in the wrong direction. This will reduce its effectiveness by 40–50%.
• 🧹 Ignore cleaning the seat. The dirt accumulated there will immediately clog the new filter.
• 🛠️ Choose a filter by eye. Even if it looks similar, the wrong size will result in gaps through which unfiltered air can leak.

Another common mistake is buying a filter without checking the article number. For example, filters for Nissan Note E11 (previous generation) not suitable for E12, although visually similar. Always check the catalog or use the vehicle's VIN number when ordering.

When is the best time to change the cabin filter: seasonal tips

The period for replacing the filter depends not only on the mileage, but also on the time of year. Here optimal periods for replacement in Russian conditions:

• 🍂 Autumn (September–October). After summer, the filter is clogged with dust, poplar fluff and insects. Replacing it before winter will ensure clean air in the cabin and normal operation of the stove.
• ❄️ Winter (December–January). If the filter has not been changed in the fall, do it before the New Year - in traffic jams due to snow porridge, the air in the cabin becomes especially dirty.
• 🌸 Spring (March–April). After the snow melts, there is a lot of sand and reagents on the roads. Replacing the filter in the spring will protect against pollen allergies.

In summer, the filter does not need to be changed if it is still in good condition, but be sure to check it after long trips on dusty roads (for example, after a vacation).

If you live in a metropolis (Moscow, St. Petersburg, Yekaterinburg), where the air is heavily polluted by exhaust gases, reduce the replacement interval to 10,000 km or once every six months.
