An ozone generator is a mobile unit that can be used to remove indoor pollutants and odour. The machine has a compartment that traps air, the oxygen in the air is then converted to ozone by an electrical discharge which simulates lightning. This method is called silent corona discharge. The electrical discharge splits the oxygen and creates single oxygen atoms which subsequently attach themselves to other oxygen atoms to form ozone.

Ozone generators are to be used with caution. Although they are considered safe in industrial and medical applications where strict safety standards are to be followed, using them at home poses danger to human health. The amount of ozone required to eliminate viruses and bacteria exceeds public health standards. Therefore, they should be used with caution, try not to be in the same space when your ozone generator is functioning. When human beings are exposed to too much ozone, it can cause diverse respiratory conditions.
