How Does a HEPA Filter Remove Allergens from the Air?

A HEPA filter removes allergens from the air through a systematic process. First, the filter captures airborne particles. HEPA stands for High-Efficiency Particulate Air. This type of filter can trap 99.97% of particles that are 0.3 microns in size. Allergens such as pollen, dust mites, pet dander, and mold spores fall within this size range.

When air passes through the HEPA filter, fibers within the filter create a maze-like structure. Larger particles collide with the fibers and are trapped. This process is effective because it relies on three mechanisms: interception, inertial impaction, and diffusion.

Interception occurs when particles follow the airflow and come in contact with a fiber. Inertial impaction happens when larger particles cannot follow the airflow as sharply, causing them to hit the fibers and stick. Diffusion affects smaller particles, making them bounce randomly and increasing their chances of colliding with the fibers.

The continuous airflow through the HEPA filter ensures a consistent removal of allergens. Because it traps a wide range of particles, the filter significantly improves air quality. This filtration process helps create a healthier indoor environment, especially for allergy sufferers.
