What Makes HEPA Filters Unique?
To qualify as a true HEPA filter, the device must meet specific standards set by the U. S. Department of Energy (DOE). A genuine HEPA filter must be able to trap at least 99.97% of particles that are 0.3 microns in diameter.
This includes a wide range of pollutants such as:
- Dust mites
- Pollen
- Mold spores
- Bacteria
- Pet dander
- Smoke particles
How Do HEPA Filters Work?
The functionality of HEPA filters is based on a combination of three mechanisms: interception, impaction, and diffusion. When air passes through the filter, particles are trapped in the following ways:
- Interception: As air flows through the filter, particles that come within one radius of a fiber will adhere to it.
- Impaction: Larger particles are unable to follow the airstream due to their mass and inertia, causing them to collide with the fibers and become trapped.
- Diffusion: Smaller particles move erratically due to Brownian motion, increasing their chances of colliding with fibers and being captured.
