If you suffer from dust related allergies, you’ll want to listen up. Silk is hypoallergenic, meaning that it prevents dust accumulation and keeps pests, like dust mites, at bay. How does this all work? Silk is produced by silk worms. The silk worm’s cocoon protects it from natural threats like dust mites, mold and fungus. Because the manufacturing process of silk doesn’t use harmful chemicals, it allows the silk to keep these defensive traits.
