Cabin filter in Renault Logan first generation (2004–2015) - a detail that many owners forget about until a persistent smell of dust appears in the cabin, and the windows begin to fog up even in dry weather. Meanwhile, replacing the cabin filter - one of the simplest maintenance procedures, which you can perform yourself in 15–20 minutes, saving on service costs. In this article, we will look at why it is important to monitor the condition of the filter, how to select and replace it correctly, and also reveal nuances that are not covered in standard instructions.

First generation Logan (code designation L90) was equipped with two types of cabin filters: ordinary dust (paper) and coal (with absorbent layer). The latter cope better with unpleasant odors and toxic exhausts, but are more expensive. Regardless of the type, the filter resource is 10–15 thousand km or 1 year of operation (whichever comes first). In the conditions of Russian roads, where dust and dirt rise all year round, this period is often reduced to 8–10 thousand km.

If you have never changed the cabin filter on your Logan, get ready for surprises: anything can be found under the hood - from leaves and insects to traces of mold. Now let's get down to business.

Signs that it's time to change the cabin filter

Many car owners are guided by maintenance regulations, but there are signals that indicate the need for replacement already now:

  • 🌬️ Weak air flow from the deflectors even at maximum fan speed. This means that the filter is clogged and is not allowing air to pass through.
  • 🤧 Constant fogging of windows, especially in rainy weather. A clogged filter interferes with air circulation, increasing humidity in the cabin.
  • 🚗 Persistent odor of dust or mold when you turn on the stove or air conditioner. This is a sign that the filter is not only clogged, but has also become a breeding ground for bacteria.
  • 🦟 The appearance of insects in the air ducts (for example, midges or spiders). They penetrate through a damaged or heavily soiled filter.

If you notice any two of these signs, don't delay replacement. In advanced cases, dirt from the filter can get into the air conditioner evaporator, which will lead to expensive repairs.

    💡

    Before purchasing, check whether the filter has soft edging around the edges. It prevents unfiltered air from entering through the gaps between the filter and the housing.

    Preparing for replacement: tools and safety precautions

    To replace the cabin filter with Renault Logan 1 no special tools needed. You will need:

    • 🔧 Flat head screwdriver (to release the clamps).
    • 🧴 Wet wipes or rag - to wipe the filter housing from dust.
    • 🕯️ Flashlight — lighting under the hood is often insufficient.
    • 🚮 Garbage bag — it is better to dispose of the old filter immediately so as not to spread dirt.

    Also prepare a new O-ring (if it comes with the filter) and respirator — when removing the old filter, a lot of dust will rise into the air.

    ⚠️ Attention: Do not replace immediately after the trip! Allow the engine to cool for 10–15 minutes, otherwise you risk getting burned on elements of the engine compartment.

    If you are allergic or suffer from asthma, take an antihistamine before work - the suspension from the old filter can cause a coughing attack.

    Step-by-step instructions for replacing the cabin filter

    Now let's move on to the process itself. On Renault Logan 1 The cabin filter is located behind the glove compartment, but it can only be reached from the engine compartment. Follow the instructions:

    Open the hood and secure it|Remove the plastic protection (jabot) under the windshield|Unscrew the 4 self-tapping screws securing the filter|Remove the old filter by pulling it up|Clear the body of debris|Install the new filter with the arrow pointing down|Assemble everything in reverse order-->

    1. Removing the frill:

      Under the windshield there is a plastic trim (jabot), which is attached to 6–8 plastic clips. Carefully pry it from the edges with a screwdriver and remove it. Do not use excessive force - the clips break easily!

    2. Filter access:

      Under the frill you will see a black plastic filter housing with a cover secured with 4 screws. Unscrew them with a Phillips screwdriver.

    3. Removing the old filter:

      Pull the filter up and it should come out without any effort. If it gets stuck, shake it slightly from side to side. Don't pull too hardso as not to tear the paper element (dust will fly in your face).

    4. Cleaning the case:

      Remove all debris from the housing (leaves, insects, dust). Wipe the inside surface with a damp cloth. If there is mold, treat it chlorhexidine or universal cleaner.

    5. Installing a new filter:

      Insert filter down arrow (on most models the arrow indicates the direction of the air flow). Make sure it fits snugly with no gaps.

    6. Assembly:

      Close the lid, tighten the screws and put the frill in place. Check that all clips snap into place.

    After replacing, turn on the stove at maximum power and check if there is any extraneous noise (for example, a whistle). If everything is done correctly, the air flow should become noticeably stronger.

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

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

    1. Correct installation (arrow should point down).

    2. The presence of a rubber seal around the edges (sometimes it sticks to the body).

    3. Deformation of the housing - if it is bent, the filter will not fit tightly. In this case, you need to straighten the plastic or replace the housing.

    Common mistakes and how to avoid them

    Even such a simple procedure as replacing the cabin filter is fraught with pitfalls. Here's what's most often done wrong:

    • 🔄 Installing the filter backwards: if you reverse the direction of the arrow, the filter will not clean, but pollute air. Always check the labeling!
    • 🧩 Incomplete cleaning of the housing: Leaves or dust left behind will quickly clog the new filter. Use a vacuum cleaner with a narrow attachment.
    • 🔩 Dragging screws: The plastic of the case is fragile - if you squeeze it, the thread will break and the lid will hang loose.
    • 🚫 Ignoring the seal: Without a rubber surround, the filter allows unfiltered air to pass through the cracks.
    ⚠️ Attention: If after replacement there is a smell of gasoline or oil in the cabin, it means that you have damaged the ventilation system pipes. Immediately check the integrity of the hoses under the hood!

    Another typical problem is creaking after installation. It occurs if the filter is pressed too tightly to the housing. In this case, bend the edges a little or check to see if there is any debris between the filter and the lid.

    How to extend the life of your cabin filter

    The average filter service life is 10–15 thousand km, but with proper care it can be increased by 20–30%. Here are some tips:

    • 🌿 Regular cleaning: Once every 3 months, remove the filter and blow it with compressed air (not water!). This will remove surface dust.
    • 🚗 Covered parking: If the car is parked outdoors, the filter gets wet and moldy faster.
    • 🔥 Humidity control: after rain or washing, turn on the stove for 5–10 minutes to dry the ventilation system.
    • 🛑 Using the conditioner: it dries the air, reducing the risk of mold growing in the filter.

    If you often drive on dirt roads, install prefilter (mesh at the air intake inlet). It will retain large particles, extending the life of the main filter.

    💡

    Carbon filters cannot be cleaned or restored! Their absorbent layer loses its properties after contamination. Paper filters can be gently blown through, but not washed.

    When to contact the service

    Although replacing the cabin filter with Logan 1 - a procedure that even a beginner can handle; there are situations when it is better to trust the professionals:

    • 🔧 The filter housing is damaged: If the plastic is cracked or warped, the entire unit may need to be replaced.
    • 🦠 Mold in the ventilation system: If the smell remains after replacing the filter, it means that fungus has settled in the air ducts. Cleaning requires special products.
