DUST (ALLERGENS)


Dust (Allergens)

Sources: Dust mites thrive in HVAC-systems because of warmth, moisture, and a good supply of food.

Health Effects:
 Many people are allergic to dust. Dust mites—microscopic spider-like creatures—are the primary source of allergens and a leading cause of asthma. Asthma-related emergency room admissions and deaths have increased in recent years (deaths tripled in ten years from 1,674 in 1977 to 4,580 in 1988).
