Saltpeter is the   deposit    of mineral salts that forms when potassium nitrate, present in home construction materials such as cement or bricks, comes into contact with oxygen and excess moisture.

Mold, humidity and saltpeter spores can also be dangerous for our health, since they are capable of promoting the development of respiratory diseases such as asthma, sinusitis, bronchitis or allergies.
