They are also an essential part of air moving devices such as terminal units, fan coils and air handlers as they remove dirt that would otherwise cause coil blockages and fan wheel imbalances.

For swimmers, a humidity range of 50 to 60% is most comfortable. However, humidity levels below 50% can significantly increase energy consumption, while humidity levels above 60% can cause damage due to mold, mildew and condensation.
