A vehicle's ventilation system plays a critical role in the comfort of the driver and passengers, especially in heavy city traffic. For owners Nissan Almera Classic with a 1.6 engine, this is not just a matter of cleanliness, but of health, since a dusty interior can cause allergies and fatigue while driving. Regular replacement of consumables allows you to maintain the performance of the stove and air conditioner at the proper level.
Many car owners are faced with the problem of finding the correct part number, as there are many variations in the catalogs. Original article The cabin filter often changes depending on the year of manufacture and modification of the heating system. Ignoring this factor leads to the fact that the purchased element simply does not fit into place or does not provide proper tightness.
In this article we will look in detail at what cabin filters suitable for your Nissan Almera Classic. You will learn not only factory part codes, but also proven analogues that can offer the best value for money. We will also look at the installation nuances and common mistakes that beginners make when performing this procedure.
Original catalog numbers and their decoding
The search for spare parts begins with determining the exact original article. For Nissan Almera Classic (B10 body, produced before 2012) there are several current codes that depend on the configuration. The most common number indicated in official dealer catalogs is 27277-EC20A. This filter is basic and fits most models with manual or automatic transmission.
However, it is worth considering that in some markets, especially in the CIS countries, there were deliveries with a different number - 27277-EC20B. The difference between them can be not only in the packaging, but also in the thickness of the filter layer. Performance they are identical, but when purchasing, always check the markings on the body of the old part with the new packaging to avoid confusion.
If you order a part through an online store, it is important to enter the code accurately, without unnecessary spaces. An error in one letter or number can lead to the shipment of a completely different spare part, for example, a filter for Nissan Note or Tierra, which have a similar but not identical design. Check for the presence of a carbon layer: some versions are equipped with carbon filters with number 27277-EC20C, which effectively trap exhaust odors.
The best analogues and manufacturers of filter elements
Original spare parts Nissan are often overpriced, forcing drivers to look for quality alternatives. There are many brands on the market offering products that are equal to, and sometimes even superior to, standard solutions in terms of filtration efficiency. The key selection criterion is compliance with the dimensions and tight fit to the frame.
Among the trusted manufacturers, it is worth highlighting the following brands that have proven themselves as reliable suppliers:
- 🌿 Mann-Filter - German quality, often superior to the original in terms of filtration density and the presence of a carbon layer.
- 🛡️ Purflux - a French brand specializing in filtration systems, characterized by a highly durable housing.
- ⚙️ Knecht / Mahle - one of the market leaders, their products are often used as original ones on conveyors.
- 💰 Febi Bilstein - good balance of price and quality, widely available in Russian stores.
When choosing an analogue, pay attention to the availability coal layer. A regular paper filter only traps dust and lint, but allows odors and exhaust gases to pass through. The carbon version contains activated carbon, which adsorbs harmful substances. For Nissan Almera Classic This is especially true in the summer when the air conditioner is running at full power.
⚠️ Attention! Cheap analogues from unknown manufacturers often have undersized dimensions, which is why air passes past the filter, entering the cabin through cracks. Do not save on your health by choosing only trusted suppliers.
- Regular (paper)
- Carbon (with activated carbon)
- Original from dealer
- Self-production

Tools and preparation for replacement
Replacement procedure cabin filter on Nissan Almera Classic does not require complex specialized equipment. You will need a minimum set of tools that any car enthusiast has. The main challenge is accessing the compartment behind the glove compartment and carefully removing the plastic clips, which can be brittle due to age.
To work you will need:
- 🔧 Phillips screwdriver (medium or small, PH2).
- 🛠️ Plastic spatula or key for removing latches (so as not to scratch the plastic).
- 🧤 Gloves (to protect hands from dust and dirt).
- 🧼 Vacuum cleaner or compressed air (for pre-cleaning the compartment).
Before starting work, be sure to open the hood and disconnect the battery terminal if you plan to remove elements located near the fuse box. Although it is often not necessary to replace the filter, the presence of voltage in the system can be dangerous if tools are accidentally shorted out. Make sure you are in a well-lit area.
☑️ Preparation for replacement
Step-by-step instructions for replacing the filter
The replacement process itself takes no more than 15-20 minutes if you have experience. If this is your first time, pay special attention to removing the plastic carefully. First of all, open the glove box (glove compartment) all the way. In it you will see a travel stop, which is a plastic tab on the right side. It must be carefully pressed or unscrewed so that the glove compartment drops down, opening access to the rear wall.
Once the glove compartment is completely lowered, you will see a plastic filter cover secured with several screws or latches. Depending on the year of manufacture, fastenings may be different. If these are self-tapping screws, unscrew them with a Phillips screwdriver. If there are latches, pry them open with a plastic spatula, being careful not to break the delicate tabs.
Remove the old filter. Pay attention to the air flow direction arrow, which is drawn on the filter housing. This is critical when installing a new part. If the arrow is directed incorrectly, the efficiency of the ventilation system will decrease and the resistance to air flow will increase. Flow direction usually points down or towards the engine compartment.
What to do if the cover does not come off?
If the lid is stuck or the latches are stuck, do not use brute force. Try rocking it slightly from side to side, after checking that all the screws are unscrewed. Sometimes it helps to lightly tap the plastic handle of a screwdriver on the edges of the lid to loosen the fit.
Before installing a new element, it is recommended to clear the cavity of accumulated dust and leaves. Use a vacuum cleaner or compressed air to remove small debris. This will prevent dirt from entering the ventilation system and extend the life of the new filter. Insert the new filter into the grooves, making sure it fits snugly against the seal.
Before installing a new filter, wipe the inside of the cover with a dry cloth to remove dust that may enter the interior when closing.
Frequent errors and operating nuances
Despite the simplicity of the procedure, car owners often make mistakes that lead to repeated contamination of the interior or damage to fastening elements. One of the most common problems is installing a filter without taking into account the direction of air flow. This leads to the filter running empty and dust entering directly into the heating system, clogging the air conditioner evaporator.
Another mistake is using the wrong size filter. If the filter is too narrow, air will flow past it, creating a “bypass” effect. If it is too wide, it will be impossible to install without deformation, which will compromise the seal. Always check the dimensions before purchasing or compare with an old sample.
⚠️ Attention! Do not try to “recondition” an old filter by shaking out dust or rinsing it with water. This destroys the fiber structure and makes it useless. The filter is a consumable item that can only be replaced.
It is also worth considering that in winter, when windows often fog up, a clean filter helps dry the air faster. A dirty filter not only does not allow air to pass through, but also becomes a breeding ground for bacteria and mold, which causes an unpleasant odor in the cabin. If you notice a musty smell when you turn on your fan, replacing the filter may not completely solve the problem and the evaporator will need to be cleaned.
Correct orientation of the filter along the air flow arrow is 50% of the success of high-quality operation of the ventilation and air conditioning system.
Replacement frequency and system maintenance
The manufacturer recommends changing cabin filter every 15,000 kilometers or once a year, whichever comes first. However, in real operating conditions, especially in large cities with high levels of air pollution, this interval should be reduced to 10,000 kilometers. Frequent replacement ensures clean air and comfortable operation of the climate system.
If you frequently drive on unpaved roads or in dusty weather conditions, check the filter every 5,000 kilometers. A visual inspection will show the degree of contamination: if the filter turns gray or black, it must be replaced immediately. Do not wait until air stops flowing through the system - this may cause the heater fan to overheat.
To extend the service life of the filter, you can use special antiseptic sprays that are applied to its surface. They help kill bacteria and prevent mold from growing inside the cabinet. However, this is only a temporary measure and regular replacement remains the only reliable way to maintain cleanliness.
Answers to frequently asked questions
Is it possible to install a filter without a carbon layer?
Yes, you can. A filter without a carbon layer (regular) traps dust and lint, but does not capture odors and exhaust gases. If you drive mainly outside the city, where the air is clean, this is a valid option. However, in the city, a carbon filter is much more comfortable.
How do you know when it's time to change the filter?
The main signs: a decrease in the intensity of air flow from the deflectors, the appearance of an unpleasant odor in the cabin, fogging of windows that do not clean for a long time. If you have not changed the filter for a long time, it is better to do it right away, without waiting for obvious symptoms.
Do I need to change the filter when replacing the timing belt?
Technically, these works are not related, but it is logical to do this at the same time, since the cabin filter is a consumable item. If the mileage replacement period is coming to an end, it is better not to delay the procedure and replace it at any opportunity.
Does the filter affect the operation of the air conditioner?
Yes, a lot. A dirty filter creates resistance to air flow, causing the air conditioner to work hard but not cool effectively. This may cause the compressor or fan to overheat.
Can the old filter be washed?
Absolutely not. Once wet, the filter material (paper or synthetic) loses its properties and is destroyed. Even if you dry it, the filtration efficiency will drop to zero. Only replacement with a new element.
