DUST MITES 
The average size of
house dust mites is 0.3mm.
About 3 mites could fit inside the dot at the end of this sentence.

 

     The house dust mite and its excrement are
one of the most widespread causes of allergies.

House dust mites cause 25% of all allergies.
50% of all asthmatic diseases are traceable to house dust mites.
5% of all people are allergic to mould fungi.
Homes are a comfortable place to live; they have an enjoyable temperature and a rather high relative humidity. But these conditions are also excellent prerequisites for the propagation of house dust mites. House dust mites are found in every household.



Allergen-containing mite excrement on fibres   

 

     It is not the mites themselves that contain allergens but their excrement, which are triggers for asthma, eczema and allergic nasal mucous membrane inflammations. Allergen-containing mite excrement on fibers (as pictured) gradually falls apart into very tiny particles. The allergenic dust then flies up into the surrounding air and is inevitably inhaled as we breathe. This also happens during regular vacuuming. And exposure to high concentrations of house dust allergens at a very early age greatly increases the risk of suffering from diseases such as asthma later on.

The house dust mite has a life span of about four months. During this time it produces about 200 times its weight in excrement and lays up to 300 eggs. This makes it clear why the concentration of allergens in a room increases exponentially within a very short time.

Even with regular and thorough housecleaning, dust particles and human skin scales continuously accumulate. Mites derive their principal nourishment from these human and animal skin scales, but also feed on fungal mold. The average size of house dust mites is 0.3mm. About 3 mites could fit inside the dot at the end of this sentence.

BUT, all dust mites and their allergens vacuumed up with the central vacuum systems are removed from the living areas for good!
