How Ozone Generators Work

Ever since we were kids, we have been taught that the Ozone layer is depleting, and we need to reduce the use of pollutants such as Chlorofluorocarbons (CFCs) – found in aerosol sprays, packing materials and refrigerants, etc. – to strengthen the ozone layer.

The ozone layer is made up of three atoms of oxygen, whereas the oxygen required for our survival is O2, i.e., two atoms of oxygen. Even though Ozone is more useful up there, it has one pertinent use down here on the surface of the earth as well.

Ozone generators can help us reign in the fortification capabilities of Ozone to help purify the air in our homes, cars, and everywhere else we are.

If you are wondering, how does an ozone generator work; let’s enlighten you – the toxic air passes through an electric charge and gets an oxygen boost and converts O2 to O3. This Ozone gas removes terrible smells, kills bacteria and mold, and destroys viruses.

Here is a video that offers a detailed explanation of ozone, ozone generators, and how to effectively clean your home, car, commercial space, etc.

To know more benefits of an ozone generator, please refer to this video, which highlights the benefits of ozone generators.

How To Purchase A Quality Ozone Generator

Generator Size

The size of the ozone generator depends on the surface area of the contaminated location and also the severity of the contamination, i.e., if the space requires rigorous cleanups. Once you are sure about these two factors, you can decide on whether you require the ozone generator for simple cleanups, or the place in question requires an intensive ozone shock treatment.

Some generators are capable of carrying out small as well as more significant purification and filtration tasks. In contrast, you also have the option to buy a generator purposed only for your cleaning needs.

Ozone Output

This measure shows how much ozone can be produced from the ozone generator, and it is measured in pounds per day or grams per hour. The higher the power rating, the more effective it will be at removing bad odors.

However, if a manufacturer doesn’t provide the power rating, chances are the generator does not output enough ozone to deliver efficient results – it’s nothing more than a gimmick. High quality and high power ozone generators can produce 350 mg per hour of ozone, but if you require more, you can find industrial-strength ozone generators with outputs as high as 10,000 mg per hour.

Area Coverage

When deciding on which ozone generator to buy, it is essential first to figure out where it will be deployed and the amount of purification required.

You may need a good-sized commercial ozone generator for offices, factories, and at times big houses. Otherwise, you can also fulfill your needs with a smaller ozone generator for hunting, cars, and individual rooms.


Portable ozone generators come in handy if you have to shift them from room to room. Plus, they do not require that much space and are quite easy to use, plug them in, and get started. If you are a regular traveler, a portable ozone generator can be carried around with you on your trips.

However, many commercial ozone generators may not be portable at all. Regardless of the size of the ozone generators, you need to make sure to stay away from the environment it is being used in – make sure there are no other people or animals in the same room as an ozone generator that’s operating at maximum power.

Build Quality & Durability

Ozone gas tends to be corrosive, which is the secret to its thorough cleaning abilities. However, the downside to this is that the materials used in building the ozone generator can also be damaged.

Therefore, you should buy an ozone generator made from materials that are resistant to ozone-led erosion such as stainless steel, Chemraz, CPVC, Kalrez, polycarbonate, silicon, titanium, etc. Materials such as magnesium, natural rubber, nylon, steel, zinc can be severely affected by ozone gas.

Ease of Use & Maintenance

Machines in the best ozone generator category must be user-friendly, and their maintenance should be easy and affordable.

Typically, you’ll need to clean the ozone generator’s input filters and ozone plates after every two to three months. Make sure you understand the intricacies of ozone generator usage and service before purchasing one.

Extra Features

Another factor to consider when choosing an ozone generator is any additional features it offers.

A good ozone generator should have some of these features:

  • Timer: A timer allows you to set when the purification process should begin, and when it should stop.
  • Fan: The ozone gas needs to be circulated thoroughly to ensure it cleans every nook and cranny in a room – choose an ozone generator with a built-in fan.
  • Ozone Control: This feature helps you choose the needed Ozone output. The ozone generator will keep the set limit as a benchmark, and stay within it.
  • Filter System: It is essential that the chosen generator has a filter system for removing dirt, dust, and other substances that might trigger allergies, plus it also rids the environment of foul smells.
  • Remote: Another feature that comes in handy to control the ozone generator from afar, and reduces the need to be in the same room as the generator.

Price & Warranty

Ozone generators come in different sizes and different prices, you can easily find something which fulfills your requirement and does not burn a hole in your pocket.

Let’s be honest; you will benefit if the machine comes with a comprehensive warranty. But, apart from checking out the warranty period for the chosen ozone generator, you should also see what coverage is being offered.

Does the manufacturer allow complete replacement, replacement of individual parts, or the warranty policy only provides free repairs?

If you cannot find all the information, reach out directly to the manufacturer for clarity.

Potential Risks When Using These Devices

Despite its many benefits, even the best ozone generator is unsafe for human beings and animals – especially for people who have asthma, COPD, or allergies.

This is because ozone gas is a lung irritant; thus, people with lung and breathing problems must stay clear of all environments that have a running ozone generator to safeguard their health. Ensure that while the ozone generator is running, you should not be in or near the vicinity.

Once the purification process finishes, allow the treated space to vent out the remaining Ozone gas and then enter.

Methods of Ozone Generation

O3, AKA ozone gas, can be generated by using the following two ways:

UV Light Method

You will be surprised to know that UV light, that the ozone layer shields us from, also leads to more ozone creation. This is why ozone generators that use the UV light method have a UV lamp that mimics the way the sun behaves. But, this requires a considerable amount of electricity as compared to the Corona Discharge method.

Moreover, the lamp requires constant maintenance because its bulb solarizes relatively quickly. Solarisation is what happens when a UV lamp is used for a reasonable amount of time – the filters within the lamp get damaged, resulting in a narrow passageway for light to pass through the filter.

The problem is that if air does not come in contact with the UV light illuminated by the lamp – no ozone will be produced. This is why these ozone generators are fitted with fans to direct air towards the lamp. The UV light method can be used as a swimming pool ozone generator and for spas where the water remains standstill and is treated by passing through a vacuum.

Corona Discharge Method

The Corona Discharge method is similar to how ozone is produced naturally – oxygen passes through an electrical field, which leads to breaking down of the oxygen molecule. The electric field works similarly to how lightning facilitates in ozone creation.

This process leaves behind two oxygen molecules with an open covalent bond AKA dangling bonds that are reactive. Consequently, these atoms or molecules attach themselves to oxygen molecules, which form O3, i.e., Ozone.

Via this method, an ozone generator can produce more than 45kgs of ozone per day; this is why among the list of the best ozone generator, the majority uses the Corona Discharge method to generate ozone.

However, if a significant amount of moisture is present in the air – nitric acid is created, which leads to a shorter life span of the equipment.

Different Uses of Ozone Generators

Air purifiers have certain limitations, as most of them use the ionic breeze type purifier that produces about 10 to 15 mg/hr. of ozone. It isn’t enough to eradicate strong odors. However, there are better alternatives on the market, such as an ozone generator that ensures effective and efficient results.

Those ozone generators listed as the best-rated ozone generator, can purify the air and disinfect surfaces via shock treatments. Some of the many uses of ozone generators include, but do not limit to:

  • Elimination of mild and severe odors, viruses, mold, mildew, and bacteria
  • Gets rid of chemical fumes and sever smells such as bar odors from restaurants and hotels.
  • Removes stubborn smells from cigarette smoke, mold, pets, and even severe odors caused by skunks.
  • An excellent choice for water purification
  • Can help in keeping food purified and clean
  • Sterilization of Medical equipment
  • Sterilization of utensils
  • Removes all allergens via shock treatment
  • Eradicates dust mites
  • Also used in cleaning up of crime scenes
  • Controls fungus production, etc.

Here is a guide to help you figure out how and why ozone generators are used.

Setting Up Ozone Generators

Ozone generators available these days are ready to use right out of the box. However, you still may have to set it up, such as fitting tubes to ozone generator for water treatment. But in all cases, you need to start by placing the ozone generator in an open area, which will provide the max potential circulation of ozone throughout the vicinity.

You can place auxiliary fans to boost circulation, which will also help in directing the ozone gas towards the pores of different materials.

First and foremost, locate the source of the problem and remove it; for instance, your house smells terrible due to pets (e.g., wet dog, etc.), cigarette smoke, mold, etc. Then choose the amount of required ozone output, and switch on the ozone generator, once done, exit the place and seal all entry points.

Ideally, for smaller spaces, three to six hours can be enough, whereas if you want to clean up a full house, it can go up to 26 to 30 hours. Also, if your ozone generator comes equipped with a timer, use it.

Set the timer to start and stop the purification process as needed, or you can buy a timer from a local hardware store or online. Remember, do not enter the house right after the ozone generator has stopped running, and give it some time to ensure that there is no residual ozone gas. Usually, it takes about 4 to 8 hours, depending on how long the purification cycle ran for and at what ozone output.

All in all, a simple process with terrific results – remember to keep the device maintained by cleaning its filters, ozone plates, etc. and it will serve you for years to come.

How To Use Ozone Generators Safely

Here are some ozone generator safety precautions, which can lead to excellent results with no adverse health effects:

  • Place signage on doors marking it off-limits while the ozone purification cycle runs to ensure no one comes in contact with harmful ozone gas.
  • Ensure no living things are in or near the contaminated area (humans, animals, and plants).
  • Bolt all the doors and windows to contain the produced ozone, which makes it safe as well as more effective.
  • Use a Timer or extension to avoid coming in contact with the generator while it’s running set the timers to switch the ozone generator on and off, or use a long extension to do the same.
  • You need to remain patient, do not enter the room even if the ozone generator has finished running. You need to wait for a few hours so that all residual ozone instances are eliminated.

People Also Ask (FAQs)

What Type of Maintenance Do Ozone Generators Need?

When and what maintenance is needed depends on the type of Ozone generator. For instance, some generators come packed with ionizers and air purifiers, which can last for a considerable amount of time. In contrast, some have UV lamps or filters which may require regular maintenance.

As a rule of thumb, you should clean your ozone plates every two to three months.

How Long Do Ozone Generators Last? Do I Need to Change Any Parts?

Typically, the bigger the ozone generator is, the more ozone it produces – this also means more effective cleaning and a longer lifespan for the generator. That being said, the life span of an ozone generator depends on the time its manufacturer has allotted for it to provide effective results, and also how serious you are when it comes to maintenance.

It is also governed by its usage; if the place in question has a considerable amount of moisture, the ozone generator will lose its abilities over time. Apart from the given time by the machine’s manufacturer, you can know when you need to replace your ozone generator for a better one when it is not entirely eliminating odors, molds, allergens, etc.

How Long Should I Run My Ozone Generator?

This depends on the type of ozone generator you have, the surface area that needs to be treated, and the severity of the situation.For instance, if you have a good-sized machine and you want to rid the area of pungent odor, it can be done by running a three to 10-hour cycle.

But if you want to get rid of severe mold, you may have to run a purification cycle for 30 hours. Remember to take all precautionary measures to ensure you and your loved one’s safety.

What Can Happen If I Am In The Room/Area While These Are Running?

Despite its brilliant sanitation and sterilization capabilities, if O3 is inhaled, it can damage your lungs. If a small quantity is inhaled, it may lead to coughing, throat irritation, chest pains, etc.

Also, it reduces our body’s power to fight infections and allergies, and it worsens the conditions of people who have asthma and other chronic respiratory diseases. Furthermore, if individuals exercise with ozone spread in and around their environment, more O3 is inhaled, this increases the risk of adverse respiratory effects.

Why Do Hunters Use These Devices?

If you are a hunter, ozone generators can remove stubborn odors from hunting gear, attire, and even your car. Place your hunting gear and attire in an enclosed area along with the ozone generator, and start a purification cycle, once done your clothes and equipment would be back to a clean and fresh state.

Remember, not to use your closet or other enclosed areas in your home, because ozone can spread through cracks and can cause harm to you and your family.
