What is an ozone generator and what is it used for?

Ozone is a gas present in the atmosphere of our planet, formed by three molecules of oxygen. Hence its notation, O ³. It is precisely from it that the ozone layer is formed, about which we always hear when the subject is global warming.

The generators are quite simple to operate: they capture the oxygen (O²) in the air and transform it into ozone, which is then released. In most cases, they run on electricity.

But what is the advantage of having an ozone generator? It is simple: this is a gas with great purification capacities. It is, for example, much more efficient than chlorine. That is why having it in your home, car or even in your professional environment can help your health!

It is said that an ozone purifier can eliminate almost 100% of fungi and bacteria from the air, as well as virtually all impurities from water. It is a very effective solution for increasing quality of life.

Did you know that the transformation of oxygen into ozone by electricity is not a human invention?

It is more or less what happens in the atmosphere. Ultraviolet radiation and electrical charges are responsible for the formation of this gas in suspension on the planet.

This is why it is often said that environments with an ozone generator switched on “smell like a storm”!

What are the uses of an ozone generator?

We have already highlighted that the ozone generator is very versatile. There are indications for each sector of the house and even for some professional environments. Therefore, let’s go to a list with the main uses that you give to an ozone generator:

  • Domestic use: Cleaning and air purification. Elimination of bacteria, fungi and germs. Remove bad odors and leave the environment totally free of contamination. It can also be used in the professional or hotel environment.
  • Culinary use: Increases the shelf life of foods when vacuum applied to them. It kills bacteria and makes it very difficult for anything to spoil. It is excellent in sterilizing kitchen utensils.
  • Automotive use: It is also able to eliminate all bad smells, bacteria and germs from the car. Carpets, for example, can collect a lot of dust mites. A small adapter allows this use to be carried out with peace of mind.
  • Use as a water purifier: It can be used both as a filter in the kitchen, purifying water for drinking, and as a pool cleaner. In this second case, it is much faster and more efficient than chlorine.
  • Use as a sterilizer: For many professionals such as dentists, barbers and brewers, the ozone generator is an incredibly effective alternative for sterilizing work objects. This is also true in the home, on objects such as toothbrushes.

There are also other professionals who can make use of ozone generators, especially those who work with chemistry or sanitation. The versatility of the device is really impressive!

What are the advantages and disadvantages of an ozone generator?

The ozone generator’s ability to clean the air and bring numerous benefits is fantastic. When used properly, it will really help your day to day life and give you an enviable quality of life.

But it’s not all flowers: ozone, when in excess, becomes dangerous. It is necessary to pay attention to regulate the generators correctly or not to leave them on constantly. Your health may be harmed in these cases.

When its presence is excessive in the environment, ozone can cause damage to the lungs, respiratory problems and worsen existing conditions, such as asthma. It is also not recommended to exercise in an environment with an ozonator.

Check the table below for advantages and disadvantages:

  • It is often portable and can be taken from one environment to another
  • It is always necessary to pay attention to the dosage of ozone
  • Ozone in excess in the air can cause serious problems
  • Power consumption

How much does it cost?

The size and utility of an ozone generator are the factors that most influence the price. There are those that are small enough to be plugged directly into the socket, and only purify the air. Others, can be applied in infinite ways and have adapters.

Therefore, the more complex the device, the higher the price. The simplest ones may cost around £150 (USD$85), with most models costing between £300 (US$300) and £400 (US$300). The best ones, with medicinal indications, can cost over £ 2,000.

Purchase criteria: Factors to consider when buying your ozone generator

There are some details specific to ozone generators that need to be taken into account when buying. We list four below:

  • Adaptability
  • Portability
  • Flow rate
  • Ease of regulation

We will explain each of them below, so you can make the best choice when buying your generator:


There are ozone generators that are capable of performing multiple functions. They can be employed indoors, purify air or water, perform all the functions we have shown in the list of the buying guide. For this, they need to be adaptable.

Objects such as extra hoses, with specific functions, and diffuser stones collaborate with this adaptability. Thus, you only need to install the necessary additional items and the product will have its main function transformed. Economy and versatility!

In case it is important for you to transport your generator to different environments and places, it needs to be small and portable. So, take a good look at the measurements and weight. Also see if it has wheels or something that facilitates the displacement.

This is not a problem if your idea is to buy a device that is fixed in one place. If this is the case, other factors should be taken into consideration.

Flow rate

The flow rate of an ozone generator is measured by the amount of gas it can release per hour. The values can be found measured in grams or litres and vary, on average, from 100 to 2000.

Depending on the function of the generator, a greater or lesser flow is necessary. To clean a swimming pool, for example, the device needs to release much more ozone than to sterilise a toothbrush. Again, you need to know what the main use will be!

Ease of regulation

We have already mentioned that in excess, ozone can be harmful to health. Therefore, you need to be able to regulate the amount of gas that will be released by the generator. The instruction manual also has to bring information about how long the device can be used in sequence.

Most models have displays that show how long the device has been on, as well as the possibility of programming shutdown and the flow rate at the moment. If this does not happen, you will always have to switch it on and off manually.

Do not overuse the generator: your health is more important than the benefits it brings!
