Air Filter

In space and astronautical engineering, an air filter is a device that removes particles and contaminants from the air in a spacecraft or space station. The air filter is an essential component of the life support system, as it ensures that the air breathed by the crew is clean and safe. In the microgravity environment of space, particles and contaminants can remain suspended in the air for long periods, making air filtration even more critical. Air filters can use a variety of technologies, including mechanical filters, electrostatic filters, and adsorption filters, to remove particles and contaminants from the air. The effectiveness of an air filter is measured by its efficiency in removing particles of a certain size, known as the filter's MERV rating (Minimum Efficiency Reporting Value).
