The air conditioner makes the air pleasant with the principle of inhaling the air in the room and cooling it instantaneously, then discharging it back into the room. However, since all kinds of pollutants in the room are sucked in, the inside of the air conditioner is easily contaminated with various fine dust and pollutants. In particular, the cooling fin, the most important part of the air conditioner, generates moisture during operation of the air conditioner, so that the contaminants are more easily adsorbed, and the accumulated contaminants help propagate low-temperature bacteria to produce various molds.

Contaminated cooling fins have more than 30% less air flow than clean cooling, which increases the power consumption by extending the cooling and heating time to the set temperature.

The contaminated cooling fins do not flow smoothly, which increases the time required for heating and cooling to reach a set temperature, thereby increasing the power consumption and causing an increase in electricity bills.

When air at room temperature passes between the aluminum fins of the cooled heat exchanger (cooling fin), the moisture contained in the air condenses and flows down. For this reason, the cooling fins are always wet with moisture during cooling so that bacteria germs and other organisms inhabit. do.
