Breathe better, live healthier! Our well-being at home depends on various factors: furniture, light, noise, room climate and odours. Would you have known? Indoors we often inhale more irritants and pollutants than on a highly frequented junction. Excessively dry air also reduces our well-being. A relative humidity level below 40 to 60 % irritates the mucous membranes and promotes coughs and sneezes. Especially children and allergy sufferers are particularly susceptible to this.
