Studies on the effects of high humidity demonstrate that high relative humidity directly affects the incidence of respiratory allergies. The survival of airborne infectious bacteria and viruses is minimized when the relative humidity is between 40 and 70%.

Epidemiological studies also found that respiratory infections affect less people living and working in a medium with low or very high humidity.

Kullhaus dehumidifiers eliminate unhealthy symptoms of wet air, mites, mold spores and other health-damaging elements.
