Ozone Generator- Air Purifier on Indoor

Ozone Generator- Air Purifier on Indoor

We all want to make our home neat and & clean. But sometimes our houses smell funky. In this case, you can use the plug-in air freshener, odor-eliminating spray, or a scented candle. These tools help to freshen the whole house. However, these can’t fulfill your requirements if you are leading with a persistent home odor. Therefore, you need to take the support of a more robust solution. In this case, an ozone generator is handy. It is a device that is mainly manufactured for producing ozone gas.

Ozone helps to make water purifier. These devices kill odor-causing bacteria by releasing gas. As a result, you can make your house neat and clean. But it is essential to choose the right model to get the best results.

Otherwise, it can cause harm. Remember, even a small amount of this gas can be harmful to your family and pets. Here, we have given elaborate details regarding ozone machines. Let’s check them out.

What is Ozone?

It is a molecule that consists of three atoms of oxygen. Two oxygen atoms form an oxygen molecule, and the third atom of oxygen can be detached and reattached to the other substances’ molecules.

What do you mean by ozone-generating air cleaners?

A few indoor air cleaners eliminate Ozone either as a byproduct due to design or intentionally. Those which emit ozone molecules purposely are known as “ozone generators”. However, these devices are known as “activated oxygen,” “super oxygen,” “trivalent oxygen,” “allotropic oxygen,” “saturated oxygen,” “mountain-fresh air,” “energized oxygen” in the market.

Good and destructive of Ozone

The Environmental Protection Agency (EPA) of the USA uses the phrase “good up high – bad nearby” to distinguish this gas in the upper and lower atmosphere. The upper atmosphere of the Ozone layer is known as “stratospheric ozone”. It helps to protect the ultraviolet radiation. But the entire layer of the Ozone layer is not protective. The lower layer is harmful to the respiratory system. This toxic level is mainly by the environment emitted chemicals.

Mainly, chemicals from automobile emissions and chemical emissions of industrial plants cause danger. Pollutants like nitrogen dioxide, fine particles, and hydrocarbons give rise to ozone concentrations. Chemical mixed ozone gas can be the reason for death.

4 Reasons to Avoid Air Purifiers that Produce Ozone

This gas is very harmful to our health. That’s why you should not use such an air purifier that generates Ozone.

  1. These Generators May Not Work at All

According to some manufacturers, this gas can render each chemical contaminant in the house harmless by generating chemical reactions. But it is not valid according to scientific research. As per their information, many harmful chemicals found indoors will take a long time to eliminate this chemical reaction procedure. However, according to some studies, the gas is unable to eliminate carbon monoxide. Along with this, this gas cannot remove mold, viruses, bacteria, and so on.

  1. The Chemical Reaction Can Be Dangerous

These generators come with some side effects. This gas reacts with multiple chemicals to make harmful byproducts. For instance, when this gas gets mixed with chemicals, it creates toxic organic substances. All these happen during the reaction process. As soon as target chemicals decreased, the harmful byproducts get rendered.

  1. Ozone Generators Do Not Remove Particulates

There is another thing that you need to know about these devices. It is that these devices are unable to eliminate particles like Dust or pollen. Therefore, it can cause allergic reactions.

However, a few models are available in the market that can combat these. Those devices that can tackle this issue come with Ionizers. It helps to disperse negatively charged ions. But recently, people have found this method less effective. According to the users, these are not so helpful to eliminate airborne molecules. For instance, it can’t remove Dust, smoke, pollen, and mold spores effectively.

  1. Impossible to Predict Exposure Levels

According to the EPA, you can’t easily determine the exact concentration of ozone gas built by the generators. It is because multiple factors are there that you need to be concerned about it.

The concentration level will be high if you want to use powerful devices in tiny spaces. However, a few factors are there that affect the concentration levels. For example, you need to check if the interior doors are open or closed. Besides, the number of things and furnishings available in the room can react with this gas. Along with this, you need to check the outdoor air ventilation level too.

Why is Ozone Dangerous?

It is a highly reactive gas. Mainly the gas is unstable and potentially toxic. The ground-level of this gas is one of the main components of smog. It can cause multiple potential health risks to people.

How Does an Ozone Generator Work

These devices convert oxygen into an Ozone. The oxygen used by these Ozone machines is taken from several sources—for example, ambient air, dry air, or concentrated oxygen. The devices add energy to the oxygen molecules. It helps the oxygen atom to recombine with other oxygen molecules part wise or temporarily.

Thus, it helps to create ozone (O3) gas. These devices are beneficial for air purification and water disinfection processes. You can get these machines available in small hand-held sizes. However, you can use the large-scale industrial models as per your needs. These are capable of building a hundred grams of Ozone per sixty minutes.

The working process of these industrial machines is quite similar to the ambient air units. However, these devices need clean and dry air or oxygen. These machines come with a corona cell. The primary purpose of its design is to create a high concentration level of this gas.

These give an electrical charge to the oxygen that passes through. This charge allows the normal oxygen to get split. As a result, those oxygen atoms turn into unstable single atoms. After that, this individual atom makes a bond with another oxygen molecule in terms of forming Ozone.

As soon as the ozone gas is generated, it gets in touch with pollutants, bacteria, viruses, or mold. Therefore, it reacts with these. After that, it breaks down the pollutants into less complex molecules. This method is known as oxidation. If Ozone doesn’t react with other molecules, then it will decompose into oxygen. This process can disinfect the air, water, etc., and reduce foul odors.

Many manufacturers think that the gas can render each containment harmless. However, you should always follow the safety rules and need to understand the structure of contaminants.

Health Effects of Ozone

According to the EPA, high levels of Ozone can cause various health effects. It may cause throat irritation, severe asthma symptoms, cough, chest pain, shortness of breath, irritation of lung tissue, and so on. Moreover, people who have respiratory problems can face serious issues. However, people who already have lung diseases must not use these machines.

What does an ozone generator do?

The primary function of these machines is to generate ozone gas. However, people use this to purify water. But when it comes to removing pollutants from the air, the gas needs to be present at a high level. According to the health experts, conditions should be under control to stop the exposition of people. However, the gas can cover the odor of pollutants. But this gas is not so helpful for air conditioning duct lining and ceiling tiles materials.

How do ozone generators produce Ozone?

These gadgets generate Ozone by breaking an oxygen molecule. Here, we have given the detailed process. Let’s check it out to know the method in detail.

Silent corona discharge:

When any electrical discharge (lightning) occurs, this gas is generated. This device splits a typical oxygen molecule. Then, it creates individual oxygen atoms. After that, these single atoms get attached to O2. As a result, it forms Ozone (O3). Silent corona discharge-ozone generators follow this rule to produce this gas.

Ultraviolet radiation:

This working procedure is similar to the ozone formation process that occurs in the upper atmosphere. In that atmosphere, the ultraviolet radiation of the sun helps the oxygen molecule to get split. Compared to the previous method, this procedure is less efficient.

Type of Ozone Generators

Ultraviolet: This type of device costs very low. These are the least efficient models. In this case, the machines split oxygen molecules with the help of UV light. Thus, it helps to generate Ozone. Compared to other types, these machines consume more time and power. It is one of the drawbacks of this type. The feature makes the product inappropriate for larger spaces. However, these are ideal for small offices, bedrooms, and hotel rooms.

Corona discharge: These generators are potent. The working process of this model is quite similar to the lightning process. It means that these devices help to break down the oxygen molecules using an electric current. Thus, it helps to produce Ozone. The gadgets generate an electric field for splitting oxygen molecules into individual atoms.

These generators are very potent and efficient, which makes them perfect for large environments. But it comes with a drawback. It is that these generators produce a lot of heat to generate a powerful electric current.

Cold plasma: As the name suggests, these devices use cold plasma to create Ozone. These models use two neon tubes to create cold plasma. But in this case, these tubes needed to be placed near each other in a sealed chamber.

When you use an electrode, it will help to electrify the chamber. During this process, it generates an electric field between these two tubes. Then, the electric field helps to split the oxygen atoms. But these machines produce little heat. However, compared to other generators, these are more expensive.

Electrolytic: These models are mainly used for water treatment. In this case, water pumps help to split oxygen molecules in water. Thus, it can generate the gas. These types of devices’ main benefit are that these models don’t leave any residue in water.



It is one of the essential features that each generator should have. With the timer’s help, you can fix the device to get switched off at a specific time. That means you don’t need to tap on any button to stop the working process. Always try to choose such a device that comes with a delayed start feature. It gives you enough time to leave your room before it starts the releasing process of this gas.


Only producing the gas will not make your job done. The gas needs to be circulated throughout your room. Thus, these can help you to eliminate foul odors from the room. You should always choose such a device that comes with a built-in fan. Select those machines which can offer you better circulation. It is a must-have feature as this gas is heavier than air.

Ozone control:

A few devices are available, enabling you to select ozone levels as per your preferences. Therefore, the device will work according to the chosen ozone input level. These devices are not able to produce more than your requirements.

Filter system:

Usually, the devices are not able to eliminate allergens from the air. That’s why before choosing the model, it is crucial to look for the filter system feature. Machines having this feature can remove dirt, Dust, dander, etc.


A few models are available which come with a remote. With the help of the remote, you can power on and off the device. Besides, with the use of this remote, you can set the timer. As a result, you don’t need to go in front of the generator. Therefore, you can now leave the room after turning on the device. Just use the remote standing in the doorway to operate the machine.


Usually, the average cost of these devices is between $22 and $200. Machines that come with compact designs are available between $22 and $50. You can use these only in small spaces. On the other hand, those costs between $50 to $90, are beneficial for larger rooms. These models come in table size. Users who want to fey the device’s advanced features need to invest $100 to $200-plus. Devices of this range come with a filter system, ozone control setting, etc.
