Abstract
A photo-electronic air purifying disinfector firstly filters out airborne impurities using a washable filter screen. It then utilizes an activated carbon filter to filter out airborne bacteria and germs. The bacteria and germs which are capable of passing through the activated carbon filter are then eliminated by extreme-UV light emitted by extreme-UV light tubes. It also utilizes a negative ion generator to boost the level of anions in the air before being discharged. These two modes operate in the following manner: the first mode involves cathodic high-voltage output that is discharged via a carbonized fibre. The ionized air is then expelled by a fan. The second mode eliminates bacteria, germs and mould from air as it passes extreme-UV light tubes by exposure to extreme-UV light emitted by these extreme-UV light tubes.
