When we want to freshen up our homes or clothes, we usually turn to a process called "airing out". However, there are many other synonyms that can be used to describe this same process. For instance, "ventilating" is a great alternative. It means to let fresh air circulate through a space, which is the same outcome as airing out. Another synonym that may be used is "deodorizing". This refers to the process by which unpleasant odours are removed from a space or item. "Refreshing" is another great synonym for airing out, which refers to making something more pleasant and revitalized by letting fresh air in. Other synonyms that can be used include "aerating", "exposing", and "circulating".
