2. OPTIONAL PARTS
2-1. AIR CLEANING FILTER
Air cleaning filter replacement: Pull to remove from the air filter.
Air cleaning filter types:
- Electrostatic anti-allergy enzyme filter (Blue)
- Deodorizing filter (Black)
ELECTROSTATIC ANTI-ALLERGY ENZYME FILTER (BLUE)
Every 3 months: Remove dirt by a vacuum cleaner.
When dirt cannot be removed by vacuum cleaning: Soak the filter and its frame in lukewarm water before rinsing it. After washing, dry it well in shade. Install all tabs of the air filter.
Every year: Replace it with a new air cleaning filter for best performance.
NOTE 1: Clean the filters regularly for best performance and to reduce power consumption.
NOTE 2: Dirty filters cause condensation in the air conditioner which will contribute to the growth of fungi such as mold. It is therefore recommended to clean air filters every 2 weeks.
