Cabin filters, pollen filters

Cabin and pollen filters are key components of a vehicle's ventilation, air conditioning, and heating systems, ensuring clean and fresh air in the cabin. They capture pollutants such as pollen, dust, soot, and harmful particulate matter, protecting passengers from the harmful effects of pollution. At Global Parts, you'll find a wide selection of used car parts, including cabin and pollen filters, perfectly matched to brands like BMW, Audi , Mercedes, Volkswagen, Mini, and more .

What is a cabin filter and cabin pollen filter?

The cabin air filter is a consumable component of the HVAC (Heating, Ventilation, and Air Conditioning) system, whose task is to purify the air drawn into the vehicle's interior. The cabin air filter traps particulate matter down to 10 micrometers (PM10), including pollen, road dust, and soot particles. In vehicles such as the Mercedes W203, the cabin air filter is an integral component of the air conditioning system and directly impacts the breathing comfort of the driver and passengers, especially during city driving and allergy season.

What are the functions of cabin and pollen filters ?

Cabin and pollen filters are crucial for passenger comfort and health:

• Air purification – Removes pollutants such as dust, pollen, soot, and harmful particulate matter from entering the vehicle interior.
• Health protection – They prevent allergies, reduce the risk of inhaling harmful substances and improve the air quality in the cabin.
• Boosts air conditioning and heating performance – Clean filters increase the efficiency of your ventilation system, ensuring better airflow.
• Reduced window fogging – Filters with appropriate permeability help remove moisture from the air, reducing the risk of window fogging.

Cabin filter in Mercedes W203 – fit and compatibility

In Mercedes-Benz W203 (C-Class) models, the cabin air filter is available in various variants depending on the body style, year of manufacture, and air conditioning type (manual or automatic). The Mercedes W203 cabin air filter is responsible for filtering air before it reaches the evaporator and heater, which translates into stable operation of the entire ventilation system. Properly fitting the cabin filter to the vent housing ensures tightness, optimal airflow, and even air distribution throughout the cabin.

Why is it worth taking care of cabin and pollen filters ?

Faulty or clogged filters can lead to reduced driving comfort and problems with the ventilation and air conditioning systems. Typical symptoms include:

• Unpleasant odor in the cabin – This may be due to the accumulation of moisture, mold or dirt in the filter.
• Poor airflow – Clogged filters restrict airflow, reducing the efficiency of your air conditioning or heating system.
• Fogged windows – A dirty filter may not effectively remove moisture from the air.
• Respiratory irritation – Inadequate filtration can cause health problems for passengers. If you need a replacement, you'll find the right used car parts at Global Parts that will restore the full functionality of your ventilation system.

Standard filters vs. activated carbon filters

The cabin air filter is available in standard or activated carbon versions. Carbon filters also adsorb gases such as nitrogen oxides, ozone, and exhaust odors, which is particularly important in city traffic. In practice, this translates into improved driving comfort in traffic jams and on congested routes. In mid-range and premium vehicles, such as the Mercedes W203, the use of activated carbon filters is a common solution for improving cabin air quality.

How to choose the right cabin and pollen filters ?

When choosing cabin and pollen filters, you should pay attention to several key aspects:

• Vehicle-specific fit – Every ventilation system has its own specific technical requirements. At Global Parts, you'll find cabin and pollen filters perfectly suited to BMW, Audi, Mercedes, Volkswagen, Mini , and more .
• Filter type – Choose a standard filter or one with a carbon layer, which also absorbs odors and gaseous pollutants.
• Technical condition – Used filters should be in good condition, without structural damage.

Table - types of cabin and pollen filters

Filter type	Type of filtration	Application	Characteristic
Standard cabin filter	Pollen, dust, particulate matter	Ventilation and air conditioning	Basic air filtration, stable flow
Anti-pollen cabin filter	PM10, allergens	HVAC system	Effective protection against allergens
Cabin filter with activated carbon	Pollen + gases and odors	City, high-traffic routes	Greater breathing comfort, odor reduction

Why is it worth choosing used cabin and pollen filters ?

Used car parts, such as used cabin and pollen filters, are an economical solution that allows you to save money while maintaining high quality. By choosing used ventilation system components, you benefit from:

• Lower costs – Used filters are much cheaper than new ones, but offer just as high quality.
• Ecology – Recycling parts supports environmental protection and reduces waste.
• A wide range of products – In our store you will find used cabin and pollen filters to the most popular car brands.

How to take care of cabin and pollen filters ?

To ensure that cabin and pollen filters function reliably for a long time, it is worth following a few rules:

• Regular replacement – It is recommended to replace filters at least once a year or every 15,000 km, and more often in difficult conditions (e.g. driving in dusty terrain).
• Avoid contamination – Keep your vehicle interior and ventilation system clean.
• Condition Check – Check the filter during periodic air conditioning and ventilation inspections. If you need a replacement, Global Parts has the right used car parts to ensure the durability and efficiency of your ventilation system.
