Basics of Ozone Generators 

An ozone generator is a great option when standard household cleaners don&#;t improve the quality of the air. When ozone reacts with odor molecules like cigarette smoke or pet odors at the molecular level, it adds an extra oxygen atom, changes the odor molecule&#;s composition, and eliminates it.

Using these powerful cleaning devices, you can effectively kill harmful bacteria and viruses in your home, office, or commercial setting. Find out about some of the best ozone generators available and what features you should look for when shopping.

The ozone machine or ozone generator produces ozone gas. Oxygen (O2) molecules are split into individual atoms by ozone generators. In the atmosphere, these oxygen molecules bond with other oxygen molecules to form ozone (O3). Either of the following two methods results in this attachment:

Silent Corona Discharge

To produce ozone molecules, electric discharge is used. Atoms of oxygen are split into singles in the air by electric energy. By attaching to other oxygen atoms in the air, these oxygen atoms form ozone.

Ultraviolet Radiation

By this process, ozone is generated similarly to how the sun&#;s ultraviolet radiation splits up oxygen (O2) to produce oxygen atoms. InterNACHI (International Association of Certified Indoor Air Consultants) considers this process to be less efficient than the corona discharge process.

Ozone Generators Buying Guide

If you want to optimize the air quality of your home or office, consider an ozone generator before buying air fresheners for your car, bedroom, or living room. Understanding ozone control and operating these machines safely is essential. Check out our guide for details about ozone generator sizes, outputs, and other features.

Size and Weight

In general, ozone generators are relatively small, except for those used in industrial settings. Weights usually range from seven ounces down to less than seven pounds, with sizes ranging from wallet-sized to the size of a toaster.

Since they are compact, they can be fitted discreetly in most rooms and can even be used in smaller spaces such as car interiors. Due to their small size, ozone generators are also portable and can easily be moved from one room to another. Many people take them along while traveling if they end up in a bad-smelling hotel suite while on a business trip.

Ozone Output

Milligrams per hour (mg/hr) are used to measure ozone production. When the generator&#;s output is higher, a larger area can be treated. Quality generators produce at least 350 mg of ozone per hour. Ozone generators of industrial size can pump out as much as 12,000 mg of ozone an hour. 

Smaller spaces, such as offices, individual rooms, and private rooms, can benefit from low-output generators. To be effective in commercial settings like hotel lobbies, generators must be much larger. A room can also be sanitized in less than an hour by using generators with a higher output for a short time. 

Portability

The convenience of portable ozone generators makes them ideal for travel or home. Several of these units weigh less than 7 ounces, and some are not much bigger than a smartphone. Compact and ergonomically designed, they can be plugged into any standard 115-volt outlet. It is easy to move portable generators from room to room in your house or from one hotel room to another.

Safety

Ozone generators, like many appliances, can pose serious health risks if misused. Your health is endangered by ozone gas. As a result of exposure to ozone, a person may feel chest pain, cough, shortness of breath, and throat irritation. Asthma and respiratory infections can also be aggravated by ozone.

Since ozone generators can pose health risks, it&#;s important to turn them off when no one is around, including pets. The ozone generator can be programmed to turn on and off at specified times, so you don&#;t have to reenter your space to shut it off manually.

You should wait until the ozone has dissipated before reentering an area where an ozone generator has finished its cycle. An hour is usually needed for this process.

Maintenance

Periodically cleaning ozone plates is necessary to maintain an ozone generator. The plates in most ozone generators can be easily removed by the user. Keeping the plates clean regularly will extend the generator&#;s life span as well as ensure its peak performance.

Features

The majority of ozone generators are equipped with a variety of features that make them easier to use and safer to operate. There should be an output control on an ozone generator as well as a fan for dispersing the ozone gas over your space.

Additionally, the generator should have a timer that lets you control when it turns on and off. The remote control is available on some generators that allow the operator to operate the unit from a distance. Airborne dust and allergens can be removed by multifunction ozone generators.

Functionality

Understanding the functionality of your ozone generator is essential before you buy. There is no doubt that experience and usage are the best ways to learn about a product. Among the different types, choose the one that most closely matches your requirements.

Price

Each person has a budget, and they want to purchase items that fit their budget. Be sure to check multiple markets to get an idea of the difference in prices so that you can get the best deal. In this way, you will get an idea of the market&#;s status. 

Brand

There is a high level of brand loyalty in the ozone generators industry. As a result, consumers tend to choose the brand they are most familiar with. Choosing popular brands ensures reliability. Each brand has its characteristics. Make sure you pick a brand that you are comfortable with. There are differences in the visual appearance of different brands. As a result, people choose different products.

Customer Consensus

If you are new to ozone generators, try consulting with experienced users. Their practical knowledge will be able to help you. It is possible to gather information about a product from people that cannot be found in mainstream media; it can either be positive or negative. In deciding which brand of ozone generators to buy, people often rely heavily on user reviews.

What to Consider When Choosing an Ozone Generator

Before users go shopping for air fresheners for the car, bedroom, and/or living room, they might want to look into purchasing the right ozone generator, which can help the air quality of a home or office. It&#;s important to understand ozone control and how to operate these machines safely. Read on to learn about the size, output, and features of ozone generators.

Types of Ozone Generators

Not all ozone generators are right for all uses. Some rely on UV energy to generate ozone, while others rely on plasma or oxygen molecules. Still, there are also models used for treating water. While each of the options is effective at creating ozone, one type may be better than others for an intended use.

Ultraviolet

Ultraviolet ozone generators are the least expensive, and least efficient, type. They produce ozone by splitting oxygen molecules with UV light. These units take comparatively more time and power to create a relatively small amount of ozone. This makes them unsuitable for larger spaces but good options for small offices, bedrooms, and hotel rooms.

Corona Discharge

Despite their unfortunate name, corona-discharge ozone generators are quite powerful. They operate in much the same way as lightning, which splits oxygen molecules with an electric current to create ozone. A corona-discharge ozone generator works by creating an electric field on a surface that splits the oxygen molecules in the room into single atoms, which instantly recombine to produce ozone gas.

Corona-discharge ozone generator models are potent and efficient, making them ideal for large environments. The downside is that it creates a significant amount of heat because it requires a lot of energy to create a powerful electric current.

Cold Plasma

Whereas corona discharge uses an electrical current and ultraviolet uses UV rays, this type of ozone generator splits oxygen atoms using cold plasma created from two neon tubes that are adjacent to each other in a sealed chamber. An electrode electrifies the chamber, creating an electric field between the two tubes.

Like a corona discharge generator, this electric field splits the oxygen atoms, which recombine to create ozone gas. Unlike corona discharge generators, cold plasma generators create very little heat but produce about the same amount of ozone gas. However, these units are bulky and significantly more expensive than other ozone generators.

Electrolytic

This type of ozone generator is used for water treatment. Water pumps into the ozone generator, which splits the oxygen molecules in water to create ozone. Unlike chemical treatments, which remain in the water, ozone water treatment dissipates into oxygen, leaving no harmful residue.

Size and Weight

Except for large ozone generators that are used in industrial settings, ozone generators are generally small. Most weigh less than 7 pounds (some weigh as little as 7 ounces) and range in size from that of a wallet to a toaster.

Their compact size allows them to fit discreetly in most rooms and even function in smaller spaces such as car interiors. Ozone generators&#; small profile means they&#;re also portable and are easily moved from room to room. Some people travel with them, too; they come in handy if users are on a business trip and end up in a foul-smelling hotel suite.

Ozone Output

Ozone output is measured in milligrams per hour. The higher the output, the larger the space the generator can treat. A quality ozone generator will produce at least 350 mg of ozone per hour, with some industrial-size ozone generators pumping out as much as 12,000 mg/hr.

Lower-output generators are suitable for offices, individual rooms, and other smaller spaces. Commercial settings, such as hotel lobbies, require much larger generators to be effective. Users can also use larger-output generators for a short time in a smaller space to &#;shock&#; the area, sanitizing an entire room in less than an hour.

Features

Most ozone generators have a host of features that make operating them safer and easier. An ozone generator should have an output control and a fan that distributes the ozone gas throughout a space.

It should also have a timer that enables users to control when the generator turns on and off. Some units have remote controls that allow the user to operate the generator from afar. Multifunction ozone generators have filters for removing dust and allergens from the air.

Portability

Portable ozone generators are convenient for home or travel. These small units weigh as little as 7 ounces, with some not much bigger than a smartphone. They are compact, feature ergonomic handles, and can be plugged into standard 115-volt outlets. Portable generators are easily moved around to different rooms in a home or can be used in hotel rooms.

Safety

Like many appliances, ozone generators can present serious health risks if they are misused. Ozone gas is a pollutant that is harmful to human health. Exposure to ozone can result in chest pain, coughing, shortness of breath, and throat irritation. Ozone can also worsen asthma and respiratory infections.

The health risks ozone generators can pose are why it&#;s essential that users operate them when there is no one around, including pets. Ozone generators have timers so users can program them to turn on and off at specified times, which prevents them from having to reenter the space to shut off the unit manually.

After an ozone generator finishes its cycle, it&#;s important to wait until the ozone dissipates before reentering the space. This usually takes about an hour.

Maintenance

To maintain an ozone generator, users need to clean the ozone plates periodically. Most ozone generators are designed so that users can easily remove the plate or plates inside the unit. By cleaning the plates regularly, users will both ensure the generator operates at peak performance and extend the lifespan of its plates.

The Advantages of Owning an Ozone Generator

There are many benefits to having an ozone generator in a home. Ozone can quickly break down odors and kill mold and mildew, making it effective at deodorizing basements, bedrooms, kitchens, and bathrooms.

An ozone generator can purify and deodorize drinking water and freshen food, helping to stave off spoilage. These powerful machines can also be used to kill harmful bacteria and viruses.

  • Ozone generators can deodorize rooms.
  • They kill harmful viruses and bacteria.
  • They purify drinking water.
  • They keep food fresh longer.

FAQs 

If you&#;re unsure about the difference between an ozone generator and an air purifier or what to do when operating ozone generator models, read on for answers to those questions and more.

Q. What is the difference between an air purifier and an ozone generator?

An ozone generator creates and releases ozone gas. Ozone sanitizes and cleans the air and objects around it. In comparison, an air purifier uses a filter that traps allergens, pollutants, and other substances before returning the air to the room.

Q. Can ozone generators be used at home? 

It is totally safe to use an ozone generator at home. However, please be advised that all pets, children and adults, and plants should be removed from your space before turning your ozone generator on.

Q. How do you use an ozone generator safely?

To use an ozone generator safely, run it only when the space is unoccupied. Purchase only an ozone generator that has a timer that will shut it off automatically. Ozone needs time to dissipate, so wait 1 hour after the generator has shut off before reentering the space.

Q. How long should I run an ozone machine for? 

As a rule of thumb, an ozone generator should run for 3 to 10 hours to ensure it properly removes odors. To ensure you are using your ozone generator for the correct amount of time, consider an air-quality monitor that measures ozone levels in your home.

Q. How long do ozone generators last?

The average lifespan of an ozone generator is about 3 years. Its lifespan largely depends on how often you use it and how regularly you clean the ozone plates.
