The best analogues: which filters to choose instead of the original

Original filters from Nissan they are not cheap (from 800 to 1,500 rubles), and their quality is often inferior to analogues from European brands. We tested several popular options and ranked the best replacements:

Brand and article	Filter type	Average price (RUB)	Features
Mann CU 22003	Coal	600–800	High density, good odor absorption, suitable for allergy sufferers.
Bosch 1 987 429 638	Dusty	450–600	A budget option, a little thinner than the original, but copes well with dust.
Framm CF 10100	Coal	700–900	Soft material, does not deform during installation, long service life.
TSN 9.7.539	Dust/coal	300–500	The most budget option, but the filtration quality is below average.

🔍 Selection advice: If you often drive on dusty roads or live in a city with high levels of pollution, it is better to take a carbon filter (for example, Mann CU 22003). It not only traps dust, but also neutralizes exhaust fumes, asphalt odors and other unpleasant odors. For normal use, the dust version from Bosch or Framm.

⚠️ Attention: When purchasing analogues, check the filter dimensions! Some manufacturers (for example, TSN) can supply filters 1–2 mm wider than the original. This will complicate installation and may warp the plastic housing.

Where is the cabin filter located? Almera Classic and how to get it

Unlike many modern cars, where the filter is hidden behind the glove compartment or under the hood, in Nissan Almera Classic it is located in a rather inconvenient place - under the dashboard on the passenger side. To get to it, you will need to remove the plastic cover.

Step by step instructions:

1. Open the glove compartment and remove all items from it.
2. Remove the glove compartment limiter (the plastic “shelf” at the bottom) - it is secured with two latches.
3. Unscrew the two screws holding the bottom of the panel (under the glove compartment). They can be hidden by stubs.
4. Lower the glove compartment down - it is attached to two plastic clips on top. Be careful not to break them!
5. Behind the glove compartment you will see a black plastic filter housing. It is secured with two latches on the sides.

📌 Important: On some modifications Almera Classic (especially early releases) the filter housing can be screwed on with a self-tapping screw. If the latches do not budge, check the presence of fasteners!

Turn off the ignition and remove the terminal from the battery (optional, but recommended)

Prepare a screwdriver with a Phillips bit and a flat-head screwdriver for prying up the latches.

Buy a new filter (check the article number!)

Prepare a vacuum cleaner or a damp cloth to clean the case from dust -->

Step-by-step replacement of the cabin filter: nuances and errors

When the filter housing is open, all that remains is to remove the old element and install the new one. However there are several critical momentsthat are often missed:

1. Cleaning the housing. Before installing a new filter, be sure to vacuum or wipe the housing to remove any accumulated dirt. If this is not done, dust from the housing will quickly clog the new filter.
2. Installation direction. The filter has an arrow indicating the direction of air flow (usually up). If you put it “back to front”, the filtration efficiency will decrease by 30–40%.
3. Checking the seal. The original filters have a soft rubber edging along the edge. Cheap analogues may not have it - this will lead to the leakage of unfiltered air.

🛑 Typical replacement mistakes:

• 🔧 Broken glove box latches. Many owners Almera Classic they break plastic clips trying to remove the glove compartment by force. It should go down and not pull out on itself!
• 🔄 Mixed sides of the filter. The arrow on the filter should point up (in the direction of air movement). If you place it upside down, dust will settle unevenly on the filter.
• 🚫 Ignoring the stub. On some cars there is an additional plastic plug after the glove compartment. It needs to be removed, otherwise you won’t be able to get to the filter.

What to do if the filter is “stuck” to the housing?

If the old filter cannot be pulled out due to moisture or dirt, do not pull it by force - this can tear the housing. Instead:

1. Spray the edges of the filter with silicone grease or WD-40.

2. Wait 5-10 minutes.

3. Carefully pry off the filter with a flat screwdriver from both sides.

4. If the filter falls into pieces, remove them one at a time so as not to clog the ventilation system.

How often should you change the cabin filter: signs of wear

The manufacturer recommends changing the cabin filter every 15,000 km or once a year. However, in Russian realities (dusty roads, frequent temperature changes, high humidity) this interval should be reduced to 10,000 km or every 6 months.

🚨 Signs that it is time to change the filter:

• 🌫️ Fogging of glass. If, even with the air blowing on, the windows quickly fog up, this is a signal of poor air circulation.
• 👃 Unpleasant smell. A musty or damp smell coming from the air ducts indicates a build-up of bacteria on the filter.
• 💨 Weak air flow. If air flows barely at maximum fan speed, the filter is clogged.
• 🤧 Allergic reactions. If you start sneezing or itching your eyes more often in the cabin, a clogged filter is to blame.

🔬 Expert advice: If you often drive off-road or live in a metropolis, you can install prefilter (mesh made of padding polyester). It traps large dust particles and extends the life of the main filter. You can make such a prefilter yourself or buy a ready-made one (for example, from K&N).

⚠️ Attention: Some “craftsmen” advise rinsing the cabin filter with water or vacuuming it. This useless! After washing, the filter loses its properties, and the vacuum cleaner does not remove germs and fine dust. It is better to spend 500 rubles on a new filter than to breathe dirty air.

Suitable for allergy sufferers	No	Yes (retains small particles)

💡 When to choose a carbon filter?

• 🚗 You often get stuck in traffic jams (coal absorbs exhaust gases).
• 🏭 You live in an industrial area with polluted air.
• 🤒 There are allergies or asthmatics in the family.

💡 When is dust enough?

• 🌳 You drive mostly on clean roads (country roads, low-dust regions).
• 💰 Do you want to save money (dust filters are cheaper and last longer).
• 🔄 Change the filter every 6-8 thousand km (in this case, the coal does not have time to wear out).

Frequently asked questions about cabin filters Almera Classic

Is it possible to drive without a cabin filter?

Technically yes, but this will lead to rapid contamination of the heater core and air ducts. The interior will be constantly dusty, and the windows will fog up. In addition, without a filter, mold spores and bacteria enter the cabin, which is harmful to health.

How to distinguish an original filter from a fake?

Original filters Nissan have:

• Clear marking of the article number on the plastic case.
• Soft rubber edging around the edge.
• Smooth folds without breaks.
• Packed in a branded bag with logo Nissan.

Fakes are often thinner, with rough seams and without sealing.

What happens if you don't change the filter for years?

The consequences can be serious:

• The heater radiator is clogged (you will have to disassemble the dashboard for cleaning).
• The appearance of mold in air ducts (can only be eliminated with special chemicals).
• Deterioration of the air conditioner (if any).
• Increased load on the fan (the motor may burn out).

Repairs in this case will cost many times more than regular filter replacement.

Is it possible to install a HEPA filter instead of a standard one?

Theoretically yes, but there are nuances:

• HEPA filters are high density, which can reduce air flow.
• They are more expensive (from 1,500 rubles) and require replacement every 5–7 thousand km.
• B Almera Classic There is no standard place for HEPA, so you will have to trim the housing or use an adapter.

For most owners, a carbon filter will be the best compromise.

How to check if the filter is installed correctly?

After installation, turn on the fan at maximum speed:

• If the air flow is strong and uniform, the filter is installed correctly.
• If the air flows weakly or with extraneous sounds (whistle, noise), the filter is installed crookedly or clogged.
• Check if there are any gaps left between the filter and the housing (you can shine a flashlight).

Also inspect the filter after a week of use - if dust has accumulated on only one side, it means it is not facing the direction of the air.
