True HEPA filters are effective due to their mechanical filtration process. They use densely packed fibers that create a maze-like structure. When air passes through the filter, particles become trapped within the fibers. This process significantly reduces airborne contaminants, improving the air’s cleanliness.

Key technical terms include:
– Filtration: The process of removing particles from air or liquid.
– Micron: A unit of measurement equating to one-millionth of a meter, used to measure particle sizes.

The mechanisms involved in true HEPA filtration include particle interception, impaction, and diffusion.
– Interception occurs when particles follow the airflow and come close to the filter fibers, where they stick.
– Impaction happens when larger particles cannot navigate the twists and turns of the airflow and collide with the fibers, becoming trapped.
– Diffusion affects smaller particles, causing them to move erratically due to their small size and Brownian motion, which increases their likelihood of being captured by a fiber.

Specific conditions that benefit from true HEPA filtration include environments with high pollution or allergen levels. Scenarios such as living in urban areas with smog or residences with pets that shed dander can significantly benefit from HEPA filters.
