Enzymes in dust mites - a cause of allergies and neurodermatitis
Dust mites (the most common species are Dermatophagoides pteronyssinus und Dermatophagoides farinae) are tiny spider-like creatures, which are especially partial to living in our mattresses where they feed on tiny fragments of skin.  Dust mite excreta contains a large amount of enzymes, which are capable of damaging our skin's protective layer and, furthermore, as proteins they are capable of causing allergic reactions.


These enzymes are particularly aggressive as they direct their attack on the body's immune system. These protease also damage other functions of the skin. The body's skin surface has a system of protective barriers (so-called "tight-junctions“) between the skin cells, which allow the exchange of substances from the outside environment.




Protective barriers (for example, the protein Occludin) prevent both the uncontrolled penetration of foreign substances or undesirable loss of valuable substances. Some forms of illness - especially neurodermatitis and particularly in the case of infants - the protective functions of the dermis can be severely damaged. The enzymes, named above, can split these protective barriers. Protective cell membranes can be damaged to such an extent that they no longer function normally. Allergens are then able to penetrate the body and cause an allergic reaction. 


It is not the dust mite which is responsible for a dust mite allergy but rather the enzymes found in its excreta! As described in the Kalixan concept for the prevention of allergies, the most important step towards an effective therapy for allergies is the avoidance of allergens.  


How can we avoid the allergens from household dust mites?

Household dust mites are found primarily in mattresses and soft furnishings. It is especially the effects of the enzymes from dust mites in the bedroom which can cause heavy colds and sneezing, asthma, red and sore eyes, which in turn lead to sleep disorders.   

The most important measure in the treatment of an allergy to dust mite allergens is to seal mattresses, quilts and pillows with a protective, anti-allergen cover (encasing).


Encasings have been proven to be one of the most effective means of reducing contamination from allergens. They effectively enclose dust mites and, in so doing, prevent the allergens from dust mites from being released out of the mattress and into the surrounding environment.  

This is an important step towards the treatment of  of adults and children who suffer from the symptoms of asthma, rhinitis or neurodermatitis.   


Sleep without dust mites – for a healthy sleep and to wake up refreshed


As a result of careful analysis and our own testing, we have expanded our range of prevention products.  Under normal use and care, these products are guaranteed to provide a consistent level of quality for at least 4 years and, thereby, help to maintain an allergen-free environment which, in turn, supports and accelerates the healing process and creates the best conditions for a healthy and recuperative sleep           


 Our prevention products can be ordered direct from our Online-Shop.

 The care instructions are available on the page describing each individual product. 

 We would be pleased to send you a sample of the fabric or further information.
