The Center for Disease Control says, “Most moulds do not affect most people. However, ALL moulds have the capacity to cause illness or distress, especially in highly susceptible persons (already ill, especially with breathing issues; very young, very old, pregnant women, others). THEREFORE, all moulds should be removed from the indoor environment! Every situation is different! For the best, specific advice, please call your local PuroClean as soon as mould is discovered.
