House Dust Mite Allergen Control

Dwelling ventilation, heating and moisture control can help reduce house dust mite growth and allergen levels through an integrated approach that includes removal of existing allergens.

Exposure to house dust mite (HDM) allergens can lead to allergic sensitization and to exacerbation of allergic conditions. The moisture criteria needed to avoid HDM are more complex and demanding than those needed to avoid mould. The reduction of mite growth may be feasible in dwellings via appropriate ventilation, heating and moisture control as part of an integrated approach that involves the removal of existing mite allergens.
