Mould belongs to the fungus family. Moulds are fungi with multi-cellular filaments called hyphae that we see growing on spoiled food or damp surfaces. In contrast, single-celled fungi are usually called yeast. Moulds are typically defined by the shape of their spores.
Moulds are prevalent in the air especially in humid conditions. Some people are not affected by them, or not aware if moulds are having any impact on their well-being. Those who are more sensitive to mould exposure can develop allergies or experience irritation in the eyes, skin, nose, throat and lungs.
Moulds thrive on moisture. Once they land on a damp spot in the home, they grow and reproduce by releasing tiny spores that float in the air. Walls, floors, carpets and furniture all provide the food that mould needs to grow. Reducing moisture is the best way to prevent or control mould growth. But first it is helpful to assess the mouldiness of our homes.
