of House Dust Mite Allergens
What are dust mites and why they allergens so dangerous?
These creatures are very tiny, about 0.1 – 0.4 mm long. They permanently reside in every home, hotel, everywhere where are bed, bed linen, carpets, curtains, textiles, upholstered furniture, in dust as well. Dust mites feed mainly on epidermis and hair shed from humans.
"House dust mites are arachnids, not insects, and are related to ticks, spiders and harvestmen."

Most common specie of dust mite in Europe is Dermatophagoides pteronyssinus.
Mites emerge as significant sources of indoor allergens and play a pivotal role in developing sensibility and triggering respiratory and skin
allergic reactions.

The most allergens are in Mites’ excrements – tiny pellets ranging from 10 to 50 µm
in diameter, are egested and accumulated in the textiles, which the mites inhabit.
Der p 1 allergen is one of major mite allergens.
Because faecal pellets are very small, dry, break down into fine dust, become airborne, inhaled by humans. Particles containing allergens, larger than 10 microns typically settle in the trachea or bronchi, while smaller dust particles below 10 microns deposited in the alveoli. The alveoli, situated at the terminal branches of our lungs, serve as the crucial site for gas exchange.
A mere gram of house dust harbors approximately 1000 dust mites, each actively producing about20 faecal per day.
