What Is Mould?
Mould is a kind of fungus. It grows where there is moisture, darkness, and less air flow. It can be black, green, white, or brown. Sometimes it looks like spots or fuzzy dust.
Mould grows fast when the air is damp or when water collects inside air ducts. Because air ducts are dark and cool, they can become the perfect place for mould to live.
When mould grows, it sends out very tiny parts called spores. These spores mix with the air and spread everywhere in your house. When you breathe them, they may cause coughing, sneezing, or even asthma problems.
At Microcare, we know how harmful mould spores can be. That is why we always advise people to act quickly when they see or smell mould and learn how to get rid of mould in air ducts safely.

| High humidity | When the air inside the home is very damp, it helps mould grow. |
| Poor ventilation | Little air movement keeps the ducts wet and dark. |
| Condensation | When warm air touches a cold duct, water forms, giving mould a home. |
