Cabin Air Filtration

The Importance of Cabin Air Filtration (Air Conditioning & Pollen Filters)

The air entering the vehicle from outside the vehicle needs a functional filtration, due to dust, soot, pollen, water particles, toxic gases, bacteria etc. in the air in the environment where the vehicles are running.

Closed circuit ventilation system in the vehicles is available thanks to air conditioning & heating.

If no quality filtration is performed in the closed circuit system, dust, toxic gas and bacteria in the amount that directly affects human health enter the vehicle from outside, and threatens the human health significantly by exposing the lungs by breathing and eyes.

Cabin Air Filter Quality and Filtration Properties

Cabin air conditioner air filter should be manufactured in technological production processes by using high technology raw materials and materials and tested and approved in advanced laboratories, compact, highly efficient, flame resistant, antibacterial, able to retain toxic gases (applicable to activated carbon filters), resistant to varying temperature and humidity conditions and easy to be disposed and/or recycled.

However, the filters produced under these conditions can be described as good quality.

Filtration Properties


Efficiency refers to the ratio of the amount of retained particles to the total amount of particles. The high efficiency filter is the filter that can retain low-micron particulates and toxic gases (applicable to activated carbon filters) at the desired life. The efficiency ratio of the air filter is expected to be 99.90% and above.

Resistance to Flame

The filter material used must be flame retardant against possible flames in the air conditioning system.


The filter material used must not produce bacteria on itself.

Retaining Toxic Gases ( Applicable to Activated Carbon Filters )

The used filter material must be able to retain toxic gases in the air and clean the air that goes into the vehicle from these gasses that are harmful to human health.

Resistance to Moisture and Heat Change

The used filter material is exposed to water, nose and variable heat conditions in the vehicle ventilation system (e.g. rainy weather). The materials used in the filter must be durable against these conditions and should not lose their function.

Filter Life

Shelf Life : It has a minimum shelf life of 3 years in its package without humidity, at -10 +40 C temperature range, without exposure to water and direct sunlight.

Life Cycle : During air filtration, the filter holds contaminants in the air that is absorbed. This leads to clogging of the filter in time. Therefore, the maintenance and replacement period that the vehicle manufacturers have reported for the replacement of the filters must be observed. If the end-of-life, clogged filter is not replaced, the air quality entering the vehicle will be lowered.

The air filtering element are designed according to the fitting system, the mounting part, the operation period of the vehicle, the maintenance period and other conditions.

Different designs are applied for cars, light commercial vehicles, public transport vehicles, heavy commercial vehicles; vehicles operating in very dusty environments such as the agricultural sector, excavation and construction sites; and air, sea and rail road vehicles.

Long-term operation in extreme dusty conditions, prolonged exposure to sooty exhaust fumes, and water absorption to the filter lead to early clogging of the filter, in other words, early termination of the life cycle.

  • Poor Quality Cabinet Air Filtration and Negative Results
  • Only price-oriented poor quality material
  • Design based on insufficient knowledge
  • Poor manufacturing conditions
  • Releasing products to the market without testing due to lack of laboratory
  • Cheapness can cause you to lose your health !
  • Insufficient air passage
  • Taking dirty air into the vehicle
  • Bacteria formation on contaminated filter
  • Allows the increase of fire in possible flames
  • Causes to heating of the air conditioner & heater motor and shortens their life cycle
