The most effective and economical solution to counteract allergy to mites is to avoid contact with allergens. Considering that 1/3 of our life is spent in bed and that it is the "house of the mites", exposure to allergens is prolonged. To avoid this risk it is necessary to completely cover the bed with effective anti-mite barrier fabrics. Mattress, pillow and duvet must be completely covered, both above and below and the device must be closed with a zip. Only in this way is it possible to guarantee impermeability to the mite.
