2-2. CATECHIN AIR FILTER
OBB483B
Catechin is a bioflavonoid that is found in green tea that has both antiviral and antioxidant qualities. In addition to
these benefits, Catechin also offers excellent deodorizing characteristics. Catechin air filter uses this compound to
not only improve air quality but also prevent the spread of bacteria and viruses in the room.
Clean the AIR FILTER about once every 2weeks. Cleaning procedure is the same as AIR FILTER (ANTI-MOLD).
Refer to the operating instructions book.
Clogged AIR FILTER may reduce the air conditioner capacity and cause dew drop or frost on the indoor unit.
