Scientific Facts

Recent studies have shown that exposure to house dust mite allergens is a significant risk factor for the development of allergic diseases, such as asthma and rhinitis (hay fever). According to Dr. Zeldin, of the National Institute of Environmental Health Sciences (NIEHS, USA), "Results from an earlier study suggest that over 45% of U.S. homes, or approximately 44 million dwellings, have bedding with dust mite allergen concentrations that exceed a level that has been associated with allergic sensitization. We estimated that 22 million homes have bedding with dust mite allergen concentrations at a level that can trigger asthma in susceptible people. So we were eager to test ways to reduce these troublesome substances."
