2. Unscrew the filter housing fasteners.
   

   On models without air conditioning, the filter housing is held on by 2-3 self-tapping screws (Phillips screwdriver). On versions with air conditioning there may be additional latches.

3. Remove the old filter.
   

   Pull it towards you. If the filter is missing, you will see an empty seat with guides.

   If the filter does not come out, check to see if it is caught in the air duct. Gently rock it left and right without applying much force.

4. Clean the seat.
   

   Remove dust and debris with a vacuum cleaner or damp cloth. For severe contamination, use an air duct cleaner (for example, Liqui Moly Klima-Anlagen-Reiniger).

5. Install a new filter.

Common mistakes when replacing the cabin filter

Even something as simple as replacing the cabin filter can be done incorrectly. Here are the most common mistakes and their consequences:

• 🔄 Installing the filter backwards.
  

  If you reverse the direction of the arrow, the filter will not clean, but pollute air, as dust will settle on the clean side.

• 🔧 Using the wrong filter.
  

  A larger filter may bend and block the air duct, while a smaller one may allow untreated air to pass through.

• 🧹 Ignoring air duct cleaning.
  

  If you do not remove the accumulated dirt, the new filter will clog 2-3 times faster.

• 🔩 Force when removing the pad.
  

  Broken clips lead to panel rattling and the need to buy new ones (clip part number: 96351565 for Lanosa).

Another typical problem is buying fake filters. There are many counterfeit branded products on the market Mann or Bosch. To avoid being scammed:

• Check for a hologram on the packaging.
• Compare the weight of the filter with the original (counterfeits are often lighter).
• Buy from authorized dealers or trusted sellers (for example, Exist.ru, Autodoc).

How to extend the life of the cabin filter?

Even the highest quality filter will last longer if you follow simple recommendations:

1. Ventilate the interior regularly.
   

   After driving in rainy weather or on dusty roads, open the windows for 5-10 minutes to dry out the ventilation system.

2. Use air duct cleaners.
   

   Once every 3–4 months, spray special compounds into the air intakes (for example, Step Up Air Conditioner Cleaner).

3. Park in the shade.
   

   Direct sunlight accelerates the destruction of the carbon layer in the filter.

4. Monitor the operation of the stove.
   

   If the air coming out of the deflectors is weak, this is a sign of a clogged filter or air ducts.

⚠️ Attention: Do not use a vacuum cleaner or water to clean the filter! Paper filters become deformed when wet, and carbon filters lose their absorbent properties.
