This includes allergens, airborne bacteria, and fine dust. Unlike basic filters, HEPA technology removes pollutants mechanically rather than masking them, helping maintain consistently cleaner indoor air.

Air purifiers designed for pet owners typically combine HEPA filters with activated carbon layers to capture pet dander, fur particles, and odours.
