TY - JOUR AB - Indoor biocontamination is recognized as a potential public health problem. The concentration of indoor pollutants is varied, depending on air filtration, air distribution systems and air cleaning devices. One portable air cleaning device, “Ionizer Air clean‐er/Air clinic” was investigated. The ability of particles to remain airborne or pass through filters depends on the size and density of particles. Air clinic device removed bacterial and mould contaminants in efficiencies up to 98.7 per cent and 67 per cent respectively, after 30 minutes of operation. After purification, Penicilliumspecies were predominant. Small particles (≤q4μm) are passed through filter mates. The negative ions produced by the device are effective for removing suspended particulates in efficiency up to 99 per cent. The disadvantages of this device are: the need to change the filter after short period of operation, and the unpleasant odour emitted from the device during operation due to ionization of particles.
