Triggers of mold and dust allergies
Dust Mites
Microscopic bugs that live in bedding, carpets, and upholstery. They thrive in warm, humid environments and feed on dead skin cells.
Mold Spores
Fungi that grow in damp areas like bathrooms, kitchens, basements, or around leaky windows. Mold spores float through the air and can trigger allergic reactions or asthma attacks.
Even if your home looks clean, these allergens may still be present in the air, mattresses, curtains, or ventilation systems.
