  • Generally the air-conditioner & heater filter must be changed after 10,000 km of driving or every 6 months.

    Polluted filter that has passed the changing period can block the air flow and inhibit the proper operation of the air-conditioner & heater, and is the cause of propagation of various harmful bacteria.

    However, it is recommended to change the air-conditioner & heater filter every 3 months in high-level fine dust condition.

  • Ultra fine dust refers to the very small dust of 2.5㎛ or less in diameter, and is almost invisible to the human eyes. Ultra fine dust is mostly produced by vehicles or fossil fuel combustion. 

    Because ultra fine dust is much smaller than fine dust, it is not filtered in the airway would mostly penetrate into the lung sac and becoming the main cause of cardiac disorder and respiratory diseases. 

    According to the IARC (International Agency for Research on Cancer) affiliated to WHO, ultra fine dust was defined as Category 1 Carcinogen in 2013. It is also stated that ultra fine dust is more harmful than second-hand smoking.
