Ozone Generators – All You Need To Know

Ozone is a molecule made up of three atoms of oxygen. These three atoms form an unstable toxic gas that is highly reactive with other gases in the air. Ozone generators are an electronic appliance whose primary function is to emit the virulent ozone gas. This emission is used to clean the air or abolish the smoke redolence. Generally, ozone formation takes places in absence of reaction of oxygen. The ozone generators are said to give out about 3 grams of ozone every hour. The most effective usage of these devices is at high concentrations when the concerned room is completely sealed and evacuated from any forms of life. This gas provides short-term relief to problems of contamination. However, it doesn’t help in case of chlorinated hydrocarbons like vinyl and plastic. While in the case of mould, the gas kills most of the spores but does not completely remove the pollutants contained in them. The ozone is just reserved to deal with these spores found on the surface of a substance hence it isn’t effective in dealing with materials such as stale furnishings.

Advantages of ozone generators

Ozone gas can successfully be used to remove impurities from water in case of some applications. The reason behind this is that very high amounts of ozone can be used in water and the chemical reactions take place underwater itself. Hence, they do not affect the human beings who aren’t in exposure to these reactions. Ozone at various concentrations can be used for water purification, bleaching, disinfection, to speed up the aging process of certain substances, removal of smoke and air purification by killing of germs like bacteria and viruses. Ozone generators in form of air purifiers eliminate tobacco smoke and other smells. They even reduce the smell of smoke in fire refurbishment jobs and also that of bacteria, mould or viruses from the garbage. These devices also help to reduce the levels of bacteria present in food plants. As a matter of fact, ozone gas has a short life cycle in the air and thus decomposes to oxygen on its own.

Disadvantages of ozone generators

The ozone generators might not be effective enough. Although some dealers say that ozone purifies every chemical impurity present in the home by reacting with them chemically; it is not completely genuine. Researches have shown that any chemical reaction will take years to completely remove the hazardous impurities present inside a home. It was also noted that ozone cannot remove gasses like Carbon Monoxide and etcetera. When it is used in concentrations less than which affects human health, it is hardly effective to remove the germs or pollutants in the air. Alongside the elimination of contaminants from the air; these ozone generators come with some side effects which are quite important to be taken a note of. The reaction of ozone with other chemicals results in the formation of hazardous by-products. Hence, the target contaminants might be removed but even dangerous byproducts may be formed in the process. Even though the ozone generators promise to remove the most harmful pollutants, they fail to take out the dust and pollen which the air contains. These particles are generally responsible for the allergic reactions in the human body. Nowadays, these generators come with an ionizer to be able of removing these particulates by producing negative ions into the air which are chemically attractive in nature. Another issue of concern is that it’s not easy to determine the exact amount of ozone being generated by this device. The concentration is high when the space of emission is small and the generator is quite powerful. The closure or opening of doors also affects this concentration. The presence of furniture in the room, the scale of air ventilation and the human proximity from the ozone generators are few other factors determining this variation of concentration. The amount of emitted ozone that is supposed to purify the air, needs to remain very low to keep the lungs of the exposed individuals safe from damage. However, such a low level isn’t enough to kill the germs present in the air. Ozone gas cannot remove bad odor. Instead, it numbs the sense of smell. The inability to perceive any smell eliminates our natural property of warning against the subjection to high concentrations of this harmful gas. Alongside being harmful to life, ozone also damages furniture made of plastic or rubber.

A better solution

It is advisable to choose High-Efficiency Particulate Air filter or HEPA filters over the ozone generators. These are much safer and more effective than the ozone generating devices. HEPA filters do not generate the hazardous ozone gas. Instead, it traps the air pollutants present inside the home without the use of any chemical reactions. These are the only type of air purifiers which meet the standards for efficaciousness set up by the Environmental Protection Agency. In some cases, these filters are combined with technologies like pre-filter and activated carbon for the betterment of efficiency. With the help of these, HEPA filters can remove all forms of contaminants from the indoor air.


Despite the ill hazards, ozone generators in Bangalore are still sold in the market. Although some agencies and governments have tried taking action against the health issues caused by these devices; none of them could gain the absolute authority to manage the ozone emission from this ozone generating devices or air purifiers and the actions haven’t been effective enough to address the critical issues. Since the composition of all products in a building cannot be determined, it isn’t possible to assume the benefits that can be expected from an ozone treatment.
