Compressed air purity is an assumption until one faced issues in the application/ end use. Contaminants in compressed air can cause harm to the equipment using compressed air and the manufacturing processes. 

Care has to be taken from the generation stage until the point of use.
This issue is addressed by use of right type of filters . Filtration is crucial and appropriate filter will help in harnessing this costly utility.

In this episode I am touching upon the filtration aspect detailing on the need , types of filters available and it’s impact on energy efficiency of the compressed air system.
