Dust mites are the leading indoor allergy trigger. They live in your bedding, carpets, curtains, and even your couch. You can vacuum and wipe all you want, but these microscopic pests and their allergy-triggering droppings still linger in the air.
Their waste contains a toxic allergen called Der p 1, which doesn't just irritate your nose, it can cause chronic inflammation and even lung issues if inhaled daily. The problem isn't just on surfaces; it's floating in the air you breathe.
