Ozone air purifiers improve the quality of air by removing most of the pollutants that normal filters can't remove. They don't filter the air, but instead, generate negative ions to clear the air of dust and pollutants. These air purifiers, as the name suggest, produce ozone, also called activated oxygen, to remove odors and other pollutants.
The activated oxygen produced by these purifiers, breaks down and oxidizes indoor bacteria, fungus, germs, molds, pathogens, viruses, and other air pollutants.
How does it Work?
Ozone is a natural component of the air that we breathe everyday. The basic oxygen molecule in the air is composed of 2 oxygen atoms, whereas, activated oxygen is composed of 3 oxygen atoms. It is produced when oxygen molecules are split into 2 separate atoms, either by lightning, high-voltage electrical charge, or by ultraviolet radiation.
The extra oxygen atom present in ozone, separates from the molecule and attaches itself to other molecules coming in its way. It oxidizes the particles by changing their chemical composition. Thus the separated oxygen atom oxidizing the particle, too is destroyed, leaving behind pure and clean oxygen.
These purifiers are useful in removing the microorganisms and viruses, which cause allergic reactions, diseases, and unpleasant odors. Thus, they help reduce the risk of allergies, bacterial or viral infections, hay fever and respiratory problems, to some extent.
Ozone air purifiers are also helpful in removing the harmful effects of particulates present in the air. Using them improves sleep, while reducing headaches and depression. They not only clean the air, but also make it smell fresh and pure.
These purifiers are best for areas with bad odors and high pollution like bars, salons, and factories.
Breathing ozone, even in small amounts, is not at all good for health. Inhaled activated oxygen can react with the compounds in the body, and can damage the lung tissue. It may also cause asthma symptoms and worsen sinus problems. Ozone air purifiers are not able to remove the particles that trigger asthma attacks, and therefore, can make asthma worse.
Ozone air purifiers may also cause side effects, like throat irritation, chest pains, coughing, and shortness of breath. It may even increase the risk of developing respiratory infections. For a person already suffering from a respiratory problem, activated oxygen inhalation can worsen the condition.
The problems caused when activated oxygen is inhaled in small amounts can be recovered, but the problems caused by longer and stronger inhalation, can't be recovered. Because of these disadvantages associated with the use of ozone air purifiers, you should be very careful while buying them.
