The quality or ability of something to be filtered or passed through a filter.
The filterability of the water was tested to ensure it met safety standards.
Filterability → It is formed from "filter" (from Old French *filtre*, meaning a device for removing impurities) and "-ability" (meaning the quality of being able to). The word "filterability" refers to the quality or capability of being filtered.
Think of a device that removes impurities ('filter') and the ability to do so ('-ability'). This helps you remember that filterability is about how well something can be filtered.
