- 20 / 30x smaller than a a grain of sand - the same size as pollen
- Rounded, Capsule-Like Shape - Unlike irregular dust particles, dust mite feces are oval or round-shaped - making them more easily inhaled into the respiratory system.
- Soft, Sticky Coating - Each fecal pellet is coated in a sticky protein matrix, allowing it to cling to fibers in bedding, carpets, and upholstered furniture, making removal more difficultContains Digestive Enzymes Dust mite feces contain powerful enzymes like Der p 1 and Der f 1, which help break down skin cells. These enzymes trigger allergic reactions, causing runny noses, sneezing, and asthma symptoms in sensitive individuals.
