Operation Manual SiBE811120 4. Operation Manual 4.1 Features Features About air purifying The powerful suction of a high airflow rate captures dust, pollen, etc. • The purifying capacity improves as the airflow rate increases. The air permeates the room at a high airflow rate. Powerful suction from 3 directions llen Po Odour Dust Effective against pollen With the high airflow rate, even pollen that readily settles because of its large particle size is quickly caught.
SiBE811120 Operation Manual What is the “Streamer” function? This function uses a “streamer discharge”, a type of plasma discharge, to generate high-speed electrons with strong oxidation power inside the air purifier, reducing or removing odour swiftly. (The high-speed electrons are generated and absorbed within the unit to ensure your safety.) The hissing sound of the streamer discharge may be heard during operation. It does not indicate any operational issue.
Operation Manual 4.2 SiBE811120 Safety Precautions Safety Precautions Before use, read these Safety Precautions to ensure proper handling of equipment.
