How to Choose Ozone Generators?

Purifying Ability

Choosing to equip your home with an environmental purifier depends primarily on the needs of those who live it. Incorrect habits, such as that of smoking in the house or not airing enough rooms daily, can affect the quality of the air in the home and make it unhealthy.

If we then consider those particular cases in which the same environment is lived by a large community, with an inevitable continuous exchange of viruses and bacteria, the need to have a device capable of purifying the air goes well beyond the price that is needed to pay to improve the quality.

In general, an Ozonator is considered as an instrument capable of reducing strong odors because it can neutralize, oxidizing them, the bacteria that are responsible for them.

Suitable for Use in Large Environments

Precisely because it is particularly powerful, the use that is recommended for this type of device is to be used for the purification of large environments, such as greenhouses or indoor farms.

If you compare the prices of these appliances with those of other purification systems that clean the air thanks to special filters, the high expense necessary to acquire particularly useful ozonation is immediately evident.

Each review highlights the need to comply with the manufacturer’s indications on the real range of action of the device.

Excessive concentrations of ozone in a closed environment can become harmful and cause the opposite effect to that desired, and that is to say, drastically worsen the air quality of the context in which the appliance is operating.


The size of the product is designed to offer user support and a structure that is comfortable to position and effective in managing the space to be sanitized.

Using a convenient handle that is mounted on the top of the Ozonator, you can transport the appliance from one area of ​​the house to another, taking care to close access to other people during the treatment.

Power and size of the product take care of the rest, to carry out an effective cleaning action in the environment, eliminating bad smells and all those bacteria that can affect the health and breathing of people at risk.

Using a convenient connection method, you can place the appliance next to a socket, and then put it into operation in a few simple steps. The compactness then pairs with the robustness of the whole, with a system that protects all the internal mechanics and the plate.


Possible applications of the ozonation system include home environments, such as living rooms, kitchens, bathrooms, and attics. The important thing is to close the door and leave the machine to work for as long as necessary.

At home, but not only, but the Airthereal proposal also applies to offices, hotels, hotel rooms from which to eliminate bad smells, as well as restaurants and corporate kitchens.

The spectrum of places and environments expands exponentially, to include also the interiors of boats and cars. What is needed is only a socket and a closed space, necessary for ozone to carry out all the sanitizing and cleaning operations of the air.

The use of the sanitizer also solves the delicate question of odors that some of our four-legged friends can leave. No problem, the sanitizing action is also activated on this front, with satisfactory results.


Once you open the package, you immediately notice the quality of the materials. The entire internal system is adequately protected so that the internal motor manages to generate the ozone necessary for cleaning the air without hindrance.

The front area includes a timer that can cover a maximum of two hours, so you can set different times and ways by choosing the area to be treated. The knob is sturdy, and the aluminum coating does not create excessive weight when moving.

It is a product designed to give the best in each of the places where it is placed. It works effectively, significantly improving the air quality, both for healthy subjects and for those who are experiencing recovery and need an area safe and free of bacteria.

How to Use the Ozone Generator

The ozone generator is a device that releases ozone into the air, sterilizing, and sanitizing it, without using chemicals. We know well how bacteria, viruses, molds, germs, spores, and parasites are practically impossible to eliminate, mainly because they are invisible to the naked eye.

How Does It Work

To block the proliferation of pathogens, you can resort to these devices that substantially saturate the ozone room, also eliminating cockroaches, mosquitoes, ticks, and other insects that are not at all pleasant and healthy to be found at home, since an environment is created practically unlivable. Besides, ozone also manages to penetrate cracks and holes.

After a certain period, this gas turns into oxygen, leaving a pleasant sense of cleanliness in the room in which the appliance was used.

Furthermore, ozone molecules can bind to those of organic and inorganic substances and thus oxidize and eradicate them, allowing us to solve also the annoying question of bad smells.

Dimensions of The Environment

Taking a look at the prices of the items offered by the market, it is easy to see how they are higher than other air purification systems. Generally, ozonizers are used in large environments (e.g., farms or greenhouses), but there are also small appliances that can be installed in the home.

Buying a model suited to your real needs is not only an economical but healthy choice. In essence, a large concentration of ozone in a small closed environment could be dangerous and deteriorate air quality.

So, if the appliance will be used for small rooms of 20 m2, buying a robust model is not only an unnecessary expense but also becomes productive and unhealthy.

Distribution, Quality and Gas Output

The technology used for the generation of ozone also determines its quality. Those who need a product capable of dealing with vast spaces and which need a strong intervention will have to point to an article that works with the corona effect, which entails a more significant expense, even in terms of consumption.

It is also essential to understand how much ozone the appliance will be able to supply, generally measured in milligrams per hour (mg / h). be wary of an article that does not report the output data, because the levels are likely to be low, to the point of risking buying a model that is practically useless for your needs.

As far as the fans are concerned, one must not be fooled by their size, but one must make sure that they are capable of pushing the ozone out of the structure, remembering also this gas is heavier than air.


When buying an electronic device, it would be advisable to have the possibility to take care of it independently, we think of replacing a fuse in the most performing models, or cleaning the source.

Furthermore, the cost of any spare parts should also not be very high. The ideal, especially for those who buy items for professional use, would be to have a service center.

Price Ranges

Depending on the type of use to which the Ozonator is intended, there are several models on the market with specific characteristics.

The difference in price to pay to obtain a model or another is also directly proportional to the number of functions that the same device can perform.

The best brand will propose solutions capable of improving the quality of the domestic air or the environment in which it is used, which does not negatively impact the health of the people or animals that live in it.

The possibility of exploiting accessory functions such as purifying water beside the internal air is offered by some models, to be preferred if they can respond to daily needs.
