Study on the ability of a new barrier to reduce airborne mite allergens.

Environmental control, especially means for blocking the release into the air of mite allergens embedded in padded furniture (mattress, pillows), represents the first important step in the treatment of IgE-mediated allergic diseases. New to the market is a home hygiene spray that creates a protective barrier on padded furniture and is thereby able to contain the dispersion into the air of allergic particles. We tested the effectiveness of the spray in vitro. Since mites, especially D. Pteronyssinus, are considered the foremost allergens, we verified the ability of the invisible barrier to impede the diffusion of the allergen and the mobile forms of these mites (Der p 1, Der 2). The product under exam created a barrier that totally blocked the passage of mobile forms and almost totally prevented the passage of allergens (> 99%).
