Aromatherapy air purifiers add a tray or sponge that holds essential oil. Air passes over the scent source before exiting the unit. Samples list aroma trays, scent diffusers, and aromatherapy functions as distinct features.
The aroma feature sits alongside HEPA filtration, not instead of it. Units with 360° air outlets disperse scent in all directions. Some models pair the tray with a washable H13 HEPA filter and air quality sensor.
Scent strength depends on oil type and fan speed. Sleep mode and timer settings can reduce or pause diffusion. Not all units with aromatherapy include a PM2.5 display or auto mode.
