• Particle Capture: HEPA filters trap at least 99.97% of particles that are 0.3 microns in size, which includes dust, pollen, mold spores, and pet dander (U.S. Department of Energy, 2021). This size range represents the most penetrating particle size, meaning that HEPA filters are very effective against various common allergens.

• Allergen Reduction: By removing allergens, HEPA filters help alleviate symptoms for individuals with allergies or asthma. Studies indicate that reducing airborne allergens can significantly decrease asthma attacks and allergic reactions (Institute of Medicine, 2000).

• Bacteria and Viruses: Research shows that HEPA filters can also capture some bacteria and viruses, contributing to a healthier environment. A study published in the Journal of Occupational and Environmental Hygiene (Koh et al., 2012) found that HEPA filters can reduce airborne pathogens, thereby lowering the risk of respiratory infections.

• Odor Removal: Some HEPA filters are combined with activated carbon layers that adsorb odors and volatile organic compounds (VOCs). This dual-action helps create cleaner-smelling air.

• Efficient Airflow: HEPA filters are designed to allow maximum airflow while still trapping contaminants. This efficiency ensures that air purifiers can cycle and clean indoor air effectively, maintaining good air quality continuously.

These factors contribute to enhancing indoor air quality in spaces where plug-in air purifiers are utilized.
