Solis Ultrasonic PureWhen spending a lot of time indoors, air quality is an important factor for our well being. Many times, indoor air is polluted with allergens, dust, odour, bacteria and other particles that can have a negative effect on our health. These health risks cannot only be reduced by cleaning the air. Air humidification is another effective weapon against health related problems as it reduces irritation of the skin and mucous membranes caused by dry air.
