How Do HEPA Filters Work in Eliminating Cat Dander?

HEPA filters effectively remove cat dander from indoor air by using a dense mat of fibers that trap tiny particles. These filters work by relying on three main mechanisms: interception, inertial impaction, and diffusion.

• Interception: Cat dander particles, which are typically smaller than 10 microns, can become trapped when they come close to the fibers of the HEPA filter. When particles pass by the fibers, the electrostatic charge attracts them, causing the particles to adhere to the filter surface.

• Inertial Impaction: This mechanism occurs when larger cat dander particles change direction rapidly while in motion. The filter fibers catch these particles as they cannot follow the airflow direction due to their inertia. Studies have shown that HEPA filters can capture particles as small as 0.3 microns with an efficiency of 99.97% (Huang, 2020).

• Diffusion: Smaller particles, often smaller than 0.1 microns, move erratically in a zigzag pattern. This random movement increases the likelihood of these particles colliding with the filter fibers and becoming trapped. Research by Zhang (2019) indicates that HEPA filters are particularly effective at removing particles in this size range as well.

HEPA filters require regular maintenance and replacement to maintain their effectiveness. They must be replaced every 6 to 12 months, depending on usage and environmental factors. This ensures the filter remains efficient in capturing cat dander and other allergens. Overall, HEPA filters provide a reliable method of reducing cat dander in homes, contributing to improved air quality and reduced allergy symptoms for sensitive individuals.
