Filtration in a vacuum cleaner involves the separation of solid particles from the airstream through the use of various filter media. As air is drawn into the vacuum, particulates such as dust, allergens, and debris collide with the filter material, which traps these particles while allowing clean air to be expelled. Effective filtration systems, such as HEPA filters, ensure that particulate matter is retained, thereby improving indoor air quality and minimizing the recirculation of harmful aerosols.
