  • Mould is a common word for fungus that grows on food, plants, damp building materials and moist surfaces (including walls, cardboard boxes, fabric, wood, etc.)
  • You can often see mould. It can look like a stain and appears in different colours. 
  • You can usually smell mould. It smells musty. 
  • If mould grows inside a building, it can affect indoor air quality and be damaging to your health.

 

  • Mould can grow indoors if the air is humid (65% humidity or higher).
  • Mould reproduces by releasing tiny invisible spores into the air. People can breathe in the spores.
  • Airborne mould spores can impact health in different ways.
