How to clean Casper air conditioner correctly and safely
Usually, people often advise you to clean the air conditioner regularly every 3 - 6 months/time or every 3 months/time if the machine operates frequently. However, this period is only approximate, and you must rely on the surrounding environmental conditions of the machine to determine a reasonable cleaning time.
If you notice signs such as: weak cold air from the Casper air conditioner, loud noises from the motor, the fan blades are covered in dust, etc., then it is time to clean the machine.

To assist users in cleaning, the Casper air conditioner is equipped with the I-Clean evaporator self-cleaning function. When this function is activated, the evaporator will freeze, then thaw to wash away the dust and dirt on the surface. Finally, the evaporator will be air-dried to maintain a clean, bacteria-free environment inside.
Using this function will help you clean the evaporator easily, limiting bacteria and mold growth in a damp environment. However, this function can only help clean part of the evaporator. For deep cleaning, you need to remove the internal parts for cleaning. If you use the I-Clean function regularly, the frequency of self-cleaning for the machine will decrease, helping you save time and costs compared to before.
