What Is Ozone Generator?

An ozone generator, also known as an ozone generator, is an air purifier that uses active oxygen (O3 - ozone) to quickly, effectively, and environmentally disinfect an entire space. It eliminates not only viruses, bacteria, and mold, but also fights against odors and allergens, including ubiquitous parasites - which will undoubtedly be appreciated by allergy sufferers, asthmatics, and anyone suffering from respiratory problems.

In addition to the air in the room, it also perfectly cleans surfaces and objects. It is therefore an ideal helper for thorough disinfection of apartments, offices, doctor's offices and other spaces, as well as textiles, furniture, plaster or children's toys.

How Does Ozonizer Work?

As we have already revealed, the secret of success lies in ozone. It is the ozone generator that produces active oxygen (O2) using an electric discharge, such as corona discharge. In this process, oxygen molecules (O2) are split into individual oxygen atoms (O). These are then combined with another oxygen molecule (O2), creating active oxygen (O3) - ozone.

Ozone is one of the strongest oxidizing agents and, as it is a gas, nothing escapes it. It permeates the entire interior, all corners and even the smallest cracks. It literally penetrates everywhere and destroys all pathogenic germs and sources of odor (animal, from waste, smoke, etc.). Once it completes its job, it reverts back to oxygen (O2), which we normally breathe.



Ozone Cleaners Are Gradually Becoming Indispensable Helpers in Many Areas and Situations. They Are Commonly Used in:

  • households and offices - they disinfect the air, surfaces and surfaces;
  • doctor's offices, waiting rooms, pharmacies - they destroy bacteria and viruses, including the SARS-CoV-2 coronavirus causing respiratory illness covid-19;
  • kindergartens and other places where children are present - they disinfect the premises and toys;
  • basements and cellars - they eliminate mold, fungi and moisture odor;
  • restaurants (kitchens) - remove the odor of food and burned oil;
  • hotels - clean and disinfect the entire room, remove all odors from textiles (mattresses, curtains, etc.);
  • cars - remove mold from the air conditioning, moisture or smoke odor from cigarettes;
  • public transport;
  • industrial spaces, etc.

In addition, ozone cleaning is widely used in hospitals for disinfecting surgical instruments or sanitizing machines and surfaces in food processing plants. It is also used for ozonation of food, during which toxic substances are removed from products, including fruit, vegetables or meat. Foods will last much longer fresh and safe. It also helps in construction, in water management, in cleaning pools or in controlling insect pests in silos.

How to Choose the Right Ozone Generator

Get your own ozone generator and you will be able to live in a much healthier environment. Its price is not high, and most importantly, your investment in it will pay off many times over in health. You will also appreciate the quiet operation, low consumption and weight - you can easily move it from room to room. However, do not underestimate the choice of the right model. It is not just about the price, but also about the quality, performance and customer satisfaction. Check out the FN NANO® brand, which offers a wide range of ozone generators for home, office and industrial use.

How to Use an Ozone Generator

The process of disinfecting with ozone is very simple. However, always follow the instructions that provide clear instructions on how to proceed during ozone treatment. In general, however, a few basic rules apply:

The most important of them is that during the ozone treatment, no people, animals, or plants should be in the room.

Before starting ozone cleaning, thoroughly clean the space (vacuum, wipe, clean and wash all surfaces), you will achieve maximum disinfection results.

Then set the cleaning time on the generator based on the size of the space. Turn it on and leave the room and close it.

The timer will announce the end of ozone treatment. However, do not enter the room for at least 1-2 hours and first let the ozone break down back into air (O2).

Then carefully ventilate the space.

How Long Does Ozone Disinfection Take

The actual process of ozone air cleaning takes from a few minutes to 2-3 hours. It depends on the power of the ozone generator and the size of the space. You can have the interior of your car disinfected in 10-30 minutes, while a hall of 200 m2 or more will be cleaned in 2-3 hours, or after several two-hour cycles, see the table above.

If you are wondering how long an ozone-treated space will remain clean, it is not easy to answer. It depends on how much the space is used and the intensity of its use. It is essentially the same as with regular cleaning. If you notice a smell, dirt, or contamination of viruses, disinfect the room again using an ozone generator.

Ozone cleaners have become a kind of certainty. Not only in the fight against the SARS-CoV-2 coronavirus, which causes covid-19 disease, but also against other microorganisms that threaten our health. If your priority is to live in a healthier and safer environment, get one for yourself.
