Causes of Contamination in Homes

Temperatures in houses and apartments vary greatly due to structural factors such as modern heat insulation, airtight windows, etc., and humidity may exceed even 70%.

Fungi, bacteria and airborne spores enter our living space and, under ideal circumstances, can multiply unimpeded – what we call a contamination – which is the case in 20-25% of all German households and industrial settings. These microorganisms can not be stopped by filters because they are much too small. Air convection spreads the germs through all rooms, a fact which goes unnoticed, since, initially, there is no odor.

In time, the oldest microbes die off, forming a biofilm which furnishes new microbes with an ideal nutrient. The dead microbes often form a visible layer of foul-smelling slime which then becomes solid fungus and progressively more difficult to remove.

A spot of mildew the size of a Euro coin gives off millions of spores. It is when these spores are inhaled that our health is placed in jeopardy.

Allergic symptoms are the most prevalent reaction to mildew spores. Among other possible reactions are skin irritations, influenza-like symptoms, a feeling of exhaustion, dizziness and even severe cases of pneumonia.
