HEPA filters are essential for people with asthma because they effectively remove airborne allergens and irritants that can trigger asthma symptoms. These filters capture small particles, such as dust, pollen, pet dander, and mold spores, improving indoor air quality.

According to the Environmental Protection Agency (EPA), a HEPA (High-Efficiency Particulate Air) filter is defined as a filter that can capture at least 99.97% of particles that are 0.3 microns in diameter. This includes many common allergens that can exacerbate asthma conditions.

The underlying reason HEPA filters are critical for asthmatics lies in their ability to reduce the presence of allergens in the air. Common triggers for asthma include dust mites, pet dander, mold spores, and various pollen types. When these particles are inhaled, they can cause inflammation of the airways, leading to asthma attacks or exacerbations of existing symptoms.

HEPA filters achieve their effectiveness through a combination of interception, impaction, and diffusion. Interception occurs when particles follow the airflow and come into contact with the filter fibers, adhering to them. Impaction happens when larger particles are unable to navigate the filter’s fibers and collide with them, effectively getting trapped. Diffusion aids in capturing the smallest particles by using random motion, reducing the chances they will escape back into the air.

Specific conditions that contribute to asthma flare-ups include high concentrations of pet dander, dust accumulation, and mold growth in damp areas. For example, a bedroom with carpets and bedding may harbor dust mites, which can trigger asthma when disturbed. Similarly, a humid bathroom could promote mold, causing breathing difficulties for asthmatics.
