Nissan Almera Classic is one of the most popular foreign cars on the secondary market, but even this reliable car has weaknesses. One of them is clogged cabin filter, which many owners forget to change for years. Meanwhile, not only the cleanliness of the air in the cabin depends on its condition, but also the operation of the ventilation system, air conditioning, and in winter, even the efficiency of glass blowing.
If you notice that a persistent smell of dust has appeared in the cabin, the air conditioner has become worse at cooling, and condensation quickly forms on the windshield - it’s time replace cabin filter. In this article we will look in detail at how to do this yourself on Almera Classic (body B10 And N16), without contacting the service. You will learn where the filter is located, which one is better to choose, and what mistakes beginners most often make.
Where is the cabin filter located in Almera Classic?
Unlike many modern cars, where the filter is hidden behind the glove compartment or under the dashboard, in Nissan Almera Classic it is located as conveniently as possible - under the hood, next to the engine shield. The exact location depends on the year of manufacture and modification:
- 🔧 On Almera Classic B10 (1995–2000) filter is located to the right of the battery, under a plastic cover.
- 🔧 On Almera Classic N16 (2000–2006) — to the left of the battery, closer to the windshield, under the rectangular plug.
- 🔧 On restyled versions (after 2003) the cover can be fixed two latches instead of one.
To avoid confusion, focus on air intake box — the filter is always located next to it. If you're not sure where exactly to look, take a look at tube going from the air intake to the passenger compartment — the filter will be in front of it.
- Every 10,000 km
- Once a year
- Only when the smell appears
- Never changed
- I don't know where he is
When should you change the cabin filter?
The manufacturer recommends replacing every 15,000 km or once a year, but in practice this interval often has to be shortened. It all depends on the operating conditions:
| Operating conditions | Recommended replacement interval | Signs of wear |
|---|---|---|
| City (clean air, little dust) | 12–15 thousand km | Faint smell of dust when turning on the fan |
| Megapolis (smog, construction dust) | 8–10 thousand km | Rapid fogging of windows, reduced air flow |
| Country roads (lots of insects, poplar fluff) | 10–12 thousand km | Visible dirt on the filter, unpleasant odor |
| Extreme conditions (sand, mud, chemical fumes) | 5–7 thousand km | Allergic reactions in passengers, fan noise |
A critical sign of wear is the appearance of mold on the filter. If you smell dampness or rot in the cabin, the filter must be replaced immediately, as mold spores are hazardous to health.
⚠️ Attention: If you often drive with the air conditioning on, the filter gets dirty faster due to condensation. In this case, check its condition every 5–7 thousand km.
Which cabin filter to choose for Almera Classic?
There are three types of filters on the market:
- 🔹 Paper (regular) - the cheapest (from 200 rubles), but they do not retain fine dust well and do not protect against bacteria.
- 🔹 Coal - average price (400–800 rubles), effective against odors and harmful gases, but clog faster.
- 🔹 HEPA filters - premium option (from 1000 rubles), even catches viruses, but requires frequent replacement.
For Almera Classic The following filter sizes are suitable:
- 📏
B10(1995–2000): 190 × 185 × 20 mm - 📏
N16(2000–2006): 205 × 195 × 25 mm
The best brands in terms of price/quality ratio:
- 🏆 Mann Filter (CU 22003) is the optimal choice for most owners.
- 🏆 Bosch (1 987 429 636) - good filtration, affordable price.
- 🏆 Fram (CF10134) - carbon version with high adsorption.
- 🏆 SCT (SA 2019) - a budget analogue for economical drivers.
If you often drive on dusty roads, take a carbon filter with an additional layer against allergens (For example, Mann Filter FP 22003). It costs more, but will last longer and protect against pollen.
Step-by-step instructions for replacing the cabin filter
The procedure takes no more than 15 minutes and does not require special tools. You will need:
- 🔧 New filter (check compatibility in the catalog!).
- 🔧 Flat blade screwdriver (for
N16Torx might come in handyT20). - 🔧 Flashlight (if you work at dusk).
- 🔧 Wet wipes for cleaning the case.
☑️ Preparation for replacement
Step 1: Open the hood and locate the filter housing.
On B10 it is located to the right of the battery, on N16 - left. The cover can be secured with latches or screws. Carefully press out the latches or unscrew the screws (on N16 sometimes used Torx T20).
Step 2: Remove the old filter.
Pull it towards you and it should come out without effort. If the filter is stuck, check for additional latches. Don't pull with forceso as not to damage the plastic case.
Step 3. Clean the body from dirt.
Leaves, insects or dust may accumulate inside. Wipe the case with a damp cloth, but do not use aggressive detergents - they can damage the plastic.
Step 4: Install a new filter.
Please note airflow direction (indicated by an arrow on the filter). On Almera Classic air moves from top to bottom, so the arrow should point to the salon.
Step 5: Close the lid and check operation.
Make sure the lid fits tightly without any gaps. Turn on the fan at maximum speed - if the air flow becomes stronger and the odors disappear, the replacement was successful.
What to do if the filter does not fit into the grooves?
If the new filter does not fit into the housing, check:
1. Correct model (perhaps you bought a filter for a different modification).
2. The presence of a rubber seal - sometimes it interferes with installation.
3. Deformation of the housing (if the previous filter was installed crookedly).
As a last resort, you can carefully trim the edges of the filter with a knife, but this is a temporary solution.
⚠️ Attention: On some Almera Classic N16 installed after 2004 double filter (two elements in one housing). If you see two sections, change both filters at the same time!
Common mistakes when replacing the cabin filter
Even such a simple procedure can go wrong if the nuances are not taken into account. Here are the most common mistakes:
- ❌ Incorrect filter direction. If you put it against the grain, the filtration efficiency will drop by 30–40%. Always look at the arrow
airflow! - ❌ Ignoring the seal. Some filters have a foam gasket - if it is not glued back, unfiltered air will enter the cabin.
- ❌ Trying to wash the old filter. Paper and carbon filters are not washable! After contact with water, they lose their properties and become a breeding ground for bacteria.
- ❌ They forget to check the drainage. There is a small hole under the filter housing for condensate drainage. If it is clogged, there will be dampness in the cabin.
Another typical problem is buying a non-original filter with inappropriate sizes. For example, a filter from Nissan Primera P11 similar in appearance, but 5 mm wider, which is why it does not fit into the grooves Almera Classic.
If after replacing the filter there is still an unpleasant odor in the cabin, check air conditioner evaporator - Most likely, dirt has accumulated there. For cleaning, use special sprays (for example, Liqui Moly Klima-Anlagen-Reiniger).
How much does it cost to replace it at a service center versus doing it yourself?
At official dealership centers, they charge from 800 to 1500 rubles (depending on the region). In small service stations the price is lower - 300–600 rubles. However, as you can see from these instructions, the procedure is so simple that it makes no sense to pay for it.
| Replacement option | Cost (RUB) | Time | Pros | Cons |
|---|---|---|---|---|
| On your own | 200–1000 (filter cost) | 10–15 min | Savings, quality control | You need to understand the structure of the car |
| Unofficial service | 500–1200 (filter + operation) | 20–30 min | Work guarantee | Risk of running into unscrupulous craftsmen |
| Official dealer | 1500–2500 (with original filter) | 30–40 min | Original spare parts, diagnostics | Expensive, time-consuming, sometimes extra charges are imposed. services |
If you decide to go to a service center, check in advance what kind of filter they will install. Some service stations save money and install cheap analogues without a carbon layer, even if you ask otherwise.

FAQ: answers to frequently asked questions
Is it possible to drive without a cabin filter?
Technically yes, but it comes with consequences:
- 🚗 Unfiltered air with dust, exhaust gases and allergens will penetrate into the salon.
- 🚗 The stove and air conditioner will work worse due to a clogged radiator.
- 🚗 During the winter period, the glass will fog up more.
If the filter has become unusable, it is better to replace it with at least the cheapest paper one than to drive without it at all.

- 🌬 Weak air flow from the deflectors even at maximum fan speed.
- 👃 Unpleasant smell in the cabin (dust, dampness, mold).
- 🔍 Visible dirt on the filter during visual inspection.
- 🌡 The air conditioner became worse cooling.
If you notice at least two of these symptoms, it’s time to change the filter.
Is it possible to clean the old filter instead of replacing it?
It depends on the filter type:
- ❌ Paper and coal - cannot be cleaned. After washing, they become deformed and lose their properties.
- ⚠️ HEPA filters — some models can be carefully vacuumed, but this is a temporary measure.
It’s better not to risk it and install a new one - its price is not commensurate with the health risks.

Does the filter seal need to be lubricated?
No, this is not necessary. The seal (if present) is usually made of a porous material that does not require lubrication. However, if the elastic has hardened and does not provide a tight fit, it can be:
- 🔧 Gently lubricate silicone grease (not aggressive!).
- 🔧 Replace with a new one (sold complete with some filters).
Do not use oils or WD-40 - they will destroy the seal material.
