This buying guide will lead you through the list of the top 5 ozone generators available on the market.

What is Car Ozone Generator, and How Does It Work?

An ozone machine is a device that creates ozone from oxygen atoms.

Ozone is a gas made of 3 molecules of oxygen. O2 is the natural gas we inhale and is made of two oxygen molecules, while ozone is an inorganic molecule with the chemical formula O3. It is both a natural and an artificial product that occurs in the Earth’s upper and lower atmosphere (the stratosphere and the troposphere). As part of the atmosphere, the ozone layer absorbs most of the harmful UV rays. Still, it is considered a respiratory hazard and a pollutant.

With ozone machines, we intentionally produce ozone gas. They do it by breaking apart oxygen into single atoms. They attach to other oxygen molecules in the air to form ozone. It is accomplished in one of the 2 ways:

  1. Ultraviolet radiation: similar process to that of how the sun’s UV radiation splits O2 into single atoms.
  2. Silent corona discharge: the machine uses electronic discharge to split O2 molecules into individual oxygen atoms. These atoms then attach to other O2 molecules to form the ozone. It is much more efficient than devices that use UV radiation technology.

How to Use Ozone Generator in Car?

Ozone odor removal is a permanent solution to the foul odor, provided you have removed the source of the smell. You can deal with your ‘smelly’ problems, including cigarette smoke, mold / musty odor, pet odor, spilled milk, and many others. You only need to follow several simple steps.

STEP 1: Preparation for the Ozone Treatment

You must start your ozone treatment by removing the source of the smell.

  • If you have a problem with mold, it is useful to mechanically clean the surfaces or contaminated areas with fungicides or other appropriate cleaning agents.
  • If the source of the smell is spilled liquid (for example, milk or juice), then you need to pre-wash the carpet or upholstery or thoroughly wash it.
  • If you are dealing with rodents or insects, the first thing you need to do is to remove their nests, urine, and feces, or any dead animals.

STEP 2: Setting the Ozone Generator

When the preparation stage is done, you can now set the ozone generator. The easiest way to do that is to put it inside the car, for example, on the front passenger seat or the armrest. The extension cord can slip through the slightly opened window or door ajar. The best way to ensure that the ozone will not ‘leak’ is to seal the rest of the opened window or door with wide masking tape, foil, or foam sheets.

STEP 3: Ozone Treatment

To ensure that ozone is sucked into ventilation ducts, once or twice during the treatment, set the ventilation system on a closed circuit and run car fans for about 15 minutes. This will remove odors from the vent system of the car. Suppose you know that a bad smell comes from, for example, an air conditioning evaporator. In that case, it is advisable to run the fans while the engine is switched off, of course, if your battery will cope.

Ozone treatment time depends on the type of odor, size of the vehicle, the intensity of the smell, and other factors – every case is slightly different. You can always check the results – after some time, you stop ozonation by turning off the ozonator and let the fresh air go into the interior. After some time, you check if the odor from the inside of your car is gone. Maybe you need to repeat the procedure several times in order to get rid of the persistent stench.

STEP 4: Ventilation

There is a residual smell of ozone after the treatment, so you need to ventilate your car. The fragrance is similar to the smell of ozone, but actually, it is a smell of residues after reaction with ozone – they accumulate on soft surfaces like upholstery, and it is temporary.

You can intensively ventilate the inside of the car and ride with windows down; you can also wipe the dashboard and seats with a damp cloth, vacuum the floor mats, or simply park the car for few hours with windows open.

It is necessary to take appropriate precautions when doing ozone treatment in your garage. Be sure to open the door to the garage when you need to start the engine because both the Ozone and Carbon monoxide in exhaust fumes are toxic in enclosed spaces. Ozone can also get out of the vehicle into the garage, so be extremely careful.

How to Buy the Best Ozone Generator for Car?

Before you plunge into the world of ozone generators, you need to analyze your necessaries. In this buying guide, you can read about each property to get an idea which product is the best option for you. Here are some of the most important aspects of ozone generators.


Each ozone generator has a certain capacity – it is the capability of the machine to release ozone gas in the surrounding, and it is measured in milligrams per hour (mg/h). It shows the amount of ozone that is going to be released in the area every hour.

With a high-capacity generator, you will be able to do the job for a very short time. Some models even have a variable ozone output, which is a convenient feature so you can adjust the capacity and the time required for the task.

Coverage Area

Your purchase should also be based on the size of the space you plan to ozonize. Most units declare a maximum working area in square feet. Still, for the usage in cars, any ozone generator will do the job – the difference is only in the time required for the task.


One convenient feature is a timer – you just need to set at what time it will start ozonizing and at what tie the machine will shut off. So, you do not need to intervene in the process, as it can be hazardous to stay in the area of ozonation.


In addition to the dimensions of the ozone generator, portability is one crucial feature for car usage. It is not just the weight; it will be easier to carry it around and move from one place to another due to its portable design. Fortunately, most of the units are hand-carry units and are easily moved.

Easy to Use

You do not want to spend too much time figuring out how your ozone generator functions; you just want to push few buttons and leave the area.


Of course, the famous budget. It determines which generator you will buy, or at least indicate which one you will consider. In these cases, the option that offers the best value for your money is the key.
