How HEPA Filters Work
The mechanism of a HEPA filter is intriguing and efficient. Here’s how it works:
1. Filtration Mechanisms
HEPA filters utilize three primary mechanisms to trap particles:
- Interception: Particles collide with fibers in the filter and become trapped.
- Inertial Impaction: Larger particles cannot navigate the bends and twists of air currents due to their mass and instead collide with fibers.
- Diffusion: Smaller particles, particularly those less than 0.1 microns, move erratically, which increases the likelihood of them coming into contact with the filter fibers.
2. The Filter Construction
HEPA filters are made of a mat of randomly arranged fibers, usually constructed from fiberglass. These fibers are positioned so that air can pass through while blocking fine particles. The effectiveness of a HEPA filter lies in the density and arrangement of these fibers, allowing them to trap a wide variety of pollutants.

What is a HEPA filter and how does it work?
A HEPA (High-Efficiency Particulate Air) filter is a type of air filter that can trap a significant amount of very small particles that other air filters might miss. Specifically, for a filter to be considered a true HEPA filter, it must remove at least 99.97% of particles that are 0.3 microns in size from the air that passes through it. This efficiency is crucial for maintaining indoor air quality, especially for individuals with allergies or respiratory issues.
HEPA filters work by using a dense mat of fibers that capture particles as air flows through them. The mechanism involves several actions: interception, impaction, and diffusion. As the air passes through the filter, larger particles get trapped by the fibers, while smaller particles are captured through diffusion and other interactions. This multi-layered approach results in cleaner air being released back into the environment, making HEPA filters highly effective in vacuum cleaners.
