HEPA filters are used for filtration of which medium?

Explanation:
HEPA filters are designed to clean the air by trapping particles as air passes through a dense fiber matrix. They remove particulates from the circulating air, not liquids, and are rated to remove most particles around 0.3 microns with very high efficiency. In pharmaceutical and cleanroom use, they help maintain air quality around products, but they aren’t used to filter liquids like parenterals, ophthalmics, or galenicals. For liquids, sterile filtration uses membrane filters designed for liquids, not HEPA. So the medium being filtered by a HEPA filter is air.
