The Aura has a 3 stage air quality indicator that indicates the purity of air around you. In order to test the Aura take it to an environment where there's smoke or smog and see the light change to red colour which indicates poor quality of air and then gradually watch it change to blue light and then green light.

The filter assembly is removable and you can wash it with clean water (not boring water) but we recommend that you change your filters every year.

The Aura shows a green light only when the air around you is pure. So if there is a green light when your start the Aura, then that means that the air around you is pure.
