Abstract

A METHOD OF REDUCING THE INHALATION OF AIRBORNE/ RESPIRABLE PARTICLES OR DROPLETS HAVING A DIAMETER OF LESS THAN 10 MICROMETRES, PRODUCED BY SPRAYING LIQUID DROPLETS FROM A SPRAY DEVICE (1), WHICH METHOD COMPRISES IMPARTING A UNIPOLAR CHARGE TO THE LIQUID DROPLETS BY DOUBLE LAYER CHARGING DURING THE SPRAYING OF THE DROPLETS FROM A SPRAY DEVICE, THE UNIPOLAR CHARGE BEING AT A LEVEL SUCH THAT THE DROPLETS HAVE A CHARGE TO MASS RATIO OF AT LEAST +/- 1 X 10-4 C/KG, WHEREBY AT LEAST 10 % BY VOLUME OF THE AIRBORNE RESIRABLE PARTICLES OR DROPLETS HAVING A DIAMETER OF LESS THAN 10 MICROMETRES IN THE VICINITY OF THE MOUTH, NOSE OR UPPER RESPIRATORY TRACT DO NOT ENTER THE LUNGS.(FIGURE 1)
