What Is a Hepa Filter and How Does It Work?

A Hepa Filter, which stands for High-Efficiency Particulate Air Filter, is a type of air filter that complies with specific standards of efficiency. To qualify as a true Hepa Filter, the filter must capture at least 99.97% of particles that are 0.3 microns in size. This includes a wide range of allergens like dust, pollen, pet dander, mold spores, and even certain bacteria and viruses.

The operation of a Hepa Filter relies on three main mechanisms: interception, inertial impact, and diffusion. These mechanisms work together to trap particles:

  • Interception: When particles flow through the filter, some of them come close enough to the fibers of the filter that they adhere to the fiber surface.
  • Inertial Impact: Larger particles that cannot easily change direction when the air changes flow paths collide with the fibers and get trapped.
  • Diffusion: Smaller particles move erratically due to Brownian motion, increasing their chance of encountering a filter fiber and becoming trapped.

Overall, a Hepa Filter is fundamental to improving indoor air quality, making it an essential component of modern air purifiers. Its efficacy in removing harmful particles from the air underscores its popularity in homes and workplaces alike, particularly for individuals with allergies or respiratory conditions.
