The 7 Best Ozone Generator Reviews & Buying Guide

“Here, you can check out the best ozone generators suitable for home and offices.”

Ozone generator is the perfect appliance to deal with stubborn and unpleasant odors which linger around regardless of how much effort and which household cleaners you use.

This indoor air purification machine works by releasing ozone gas into the air that outbreaks bad smells at its molecular level and changes its composition to eradicate the odor.

It is capable of eradicating stale cigarettes, pet smells, mildew, smoke, and other stubborn smells.

If you want to invest in the best ozone generator, then we recommend considering the below factors.

• Ozone Output: It represents the capacity of the appliance to purify the air and measured in mg/hr. A generator with a higher output will make it easily treat larger space. Ozone generators are available with output range from 350 mg/hr to 12000 mg of ozone per hour. Choose the ozone output of a generator based on the size of the room/space.
• Coverage Area: The coverage area (given in square feet) of an ozone generator should be at least equal to the room size where you want to place the generator. If the coverage area is less, then you won’t get satisfactory results from the generator. Similarly, a generator with a wide coverage area is used for multiple locations.
• Timer: It would be a bit risky to get into the room to turn off the generator. With this timer option, you can schedule a specific time for the generator to turn on/off without pressing the buttons manually. Also, a model with a delayed start feature will let you come out of the room before a generator starts releasing ozone gas into the air.

It is important to purchase an ozone generator as careful analysis – because a wrong option can cause harm humans, plants, and pets if not used properly.

Buying Guide For Ozone Generator

Till now, you came through the best ozone generators available in the market. Among them how do you know which product is your best-suited option? For this, you need to analyze your necessities before buying. So, to help you in making the final decision, we are providing a guide with all essential information about ozone generators.

Here are some must to consider factors while shopping for an ozone generator.

1. Type

One has to know about its different types available for ozone generators and how to safely use them before picking one for your office or home. Ozone generators come in 4 main types – ultraviolet, corona discharge, cold plasma, and electrolytic. Let’s know about them in detail.

• Ultraviolet 

This ultraviolet ozone generator splits the oxygen molecule by using ultraviolet (UV) light to create ozone. They take relatively more power and time to generate a little of ozone. Thus, it is a perfect option for small spaces (like small offices, hotel rooms, and bedrooms), yet not an ideal to clean air in larger spaces (like commercial use or large rooms). It is the least efficient type and least expensive as well.

• Corona Discharge 

This corona discharge ozone generator is a powerful type that uses electric current for splitting oxygen molecules and thereby generate ozone. They create an electric field on the surface, in which the oxygen molecules get splits into individual single atoms. Then it recombines quickly to create ozone gas.

It is efficient economical, and potent that won’t require a long time to sterilize the space. Thus, it is a perfect option for large spaces, yet it depends on the size of the space. However, it produces some heat while operating, why because, to produce a powerful electric current, the machine needs heaps of energy.

• Cold Plasma 

This cold plasma ozone generator uses cold plasma generated from two adjacent neon tubes in a sealed chamber for splitting oxygen molecules. Here, an electrode will create an electrical field by sending an electric current through the chamber. Then it splits the oxygen atoms and re-combine to produce ozone gas.

Not like corona discharge models, they produce less heat, yet create the equal quantity of ozone gas. This machine is not common to use in households. Compared to its counterparts, these are more expensive, and bulky as well.

• Electrolytic  

This electrolytic ozone generator is designed to use for water treatment. Here the molecules get split into oxygen, hydrogen, and ozone. Water pumps into an ozone generator that splits oxygen in the water to produce ozone. This ozone water treatment will dissolve into oxygen and won’t leave any harmful residues. It is the least common type that uses water as its starting substrate. It is less likely used in the home, yet a few options are used in a commercial setting.

2. Size and Weight

In general, ozone generators are comparatively small in size, except those we use in industrial/commercial settings are large size. The weight of most generators is less than 7 pounds (a few weigh even 7 ounces). The size range of these generators will be from wallet size to toaster-size.

Their lightweight and compact size will allow them easy to fit in any room or work well even in smaller areas like car interiors. Its small profile makes it portable and easy to move from one room to another. A few people even like to carry this handy machine while traveling, especially on tours or business trips to wind-up in a smelly hotel room.

3. Ozone Output

Ozone output is essential to consider while shopping the ozone generators. It is given in milligrams per hour (mg/hr). A generator with a higher output value can handle the larger space. Usually, a decent quality ozonator produce a minimum ozone of 350 mg/hour, while industrial purpose ozone generators will pump out a maximum of 12,000 mg of ozone per hour.

• A lower output ozone generator will produce a maximum of 7000 mg/hr is the best option for apartments, smaller rooms, and cars, as it suits areas up to 1000 square feet.
• A larger output ozone generator will produce a maximum of 10,000 mg/hr is the best option for larger homes or commercial purposes. It will clean and sterilize the air in space that ranges from 2000 – 3000 square feet.

Based on the room’s size and ozone output, the generator will take 5 – 20 minutes to effectively clean and sterilize the air. A general rule is that the higher the output level, the more space it can clean and in a shorter time.

Using a higher output ozone machine in a small space for a short time will shock the area that let you sanitize the whole room a couple of times within an hour. It is worth selecting an ozone generator that is perfectly suitable for the size of the intended space for constant use.

Most generator manufacturers reveal the total quantity in their product spsecifications. In case, if you don’t find it on a particular model, the appliance won’t produce sufficient ozone to make it effective.

4. Portability

Usually, almost all ozonators are portable, which makes it suitable for travel or home usage. Thus, this small unit weighs as less as 7 ounces, yet not more than a smartphone. These are compact and has ergonomic handles that you have to plug into a standard 115-volt outlet. Thus, these portable generators can be moved /carried easily to other rooms around the home or in hotel room.

5. Safety

A misused ozone generator will cause serious health risks. So, one has to be careful and follow some safety measures while using this generator. It is a pollutant gas that harms your health. Over exposing to ozone may result in coughing, chest pain, asthma, throat infection, shortness of breath or other respiratory problems.

Due to these health risks, you can operate the ozone generators when no one is there around the area. Most generators feature a timer option that let you program them to turn on/off them at specific times without having your presence manually. Also, the doors have to be sealed properly to prevent the ozone from getting its way to other areas/rooms of the home.

After finishing the cycle, it is crucial to wait for an hour (or more) till the ozone dispels beforehand re-enter the space.

6. Other Features

For the safe, easy, and effective operating of these ozone generators, most manufacturers include a host of features (add-ons). Here are some of those features.

• Coverage Area 

Depending on the size of the area you want to treat, scale the ozone generator purchase and pick the right option. Mostly, square feet are used to declare the maximum working area of these generators.

• Timer 

This essential feature will not let you be in the same room for tuning on and off the generator. Also, you can set the schedule to work a generator within a specific time without any need to press buttons manually. Pick a model with a delayed start feature that will discharge ozone after you left the room. It offers complete control over the generator when it turns on & off.

• Ozone Control 

A few ozone generators give you complete control over selecting a desired level of ozone. The generator will discharge the chosen level of ozone and thereby limit the potential hazard without producing more than you selected/required.

• Fan  

To remove stubborn odor and sterilize the indoor air effectively, the gas produced by the generator has to circulate all over the room. For this, select an ozone generator having a good fan to distribute the gas throughout your space. Since ozone is a heavier gas than air, pick a model with a fan directed upwards for effective circulation. Some models offer variable fan speeds, which pumps more gas properly into the room at a quick rate and thereby dissipate a strong odor.

• Filter System  

Usually, an ozone generator is not capable to remove allergens from the air all by itself. So, ensure to select a model with a proper filter system to remove the dust, dirt, dander, and other allergens along with odors effectively.

• Remote  

Most modern ozone generators feature a remote to control all their operations. It let you turn on/off the machine, set a timer along with ozone output without doing it manually in front of the machine. You can operate the generator by standing in the doorway with this remote.

7. Durability and Build Quality

The deep cleaning ability of ozone gas is due to its corrosive nature, which, in turn, damages the materials used in manufacturing the generator. So, purchase an ozone generator that is made from ozone erosion-resistant materials, such as stainless steel, silicon, titanium, Chemraz, polycarbonate, Kalrez, CPVC, and so on. While materials like natural rubber, steel, zinc, magnesium, and nylon get affected severely by this ozone gas. It is a must to consider the build quality, durability and reliability of the product before making its purchase.

8. Maintenance

Periodic cleaning of ozone plates is required to maintain an ozone generator effectively. Most models will allow the user to remove the plates inside the unit easily. Regular cleaning of the plates will ensure the machine operates at its peak performance and extend the plates’ lifespan as well.

9. Operating Costs

Other than electricity/power cost, there are some extra operating costs including replacing ceramic ozone plates, filters, and UV bulbs. Each ozone generator comes with a minimum of one consumable, ceramic ozone plates and one filter. UV bulbs are less common, while units do not use UV light, the bulbs will long-lasting.

10. Brand

We suggest you choose a trustworthy brand and verified customer reviews on the given product along with its comprehensive warranty. Ensure to check the most recent product reviews and customer support provided by the manufacturer before buying.

11. Price

The price of ozone generators will be from $22 – $200, in which you have to pick the one offering decent quality and required features that come within your budget.

• A compact unit without many features that handle small spaces will cost you around $22 – $50.
• A table-sized model with special features that handle larger rooms will price between $50 – $90.
• A commercial-grade model having special features like a filter system, ozone control setting, and other special features will cost you $100 – $200 (or more).

12. Warranty

The warranty of an ozone generator is a must to consider factor to prevent end-up with a weaker and incompatible choice. Take a look at the warranty period allotted by the manufacturer to get a clear idea of its overall reliability. An ozone generator with a minimum of a 1-year warranty is most admirable. Also, some manufactures offer 3-year or 5-year long warranty on their product.

What is an Ozone Generator, and How Does it Work?

An ozone generator produces and releases ozone gas into the air to remove unpleasant odors, kill micro-organisms and sterilize the indoor air. This indoor air purification machine can be used in both household and commercial places. Yet, the user has to take some specific care while using this generator indoors. If not used correctly, it may harmful to both humans and animals.

Coming to its working procedure, the released ozone will attach to the dust particles and other contaminators in the air. Usually, the generator produces ozone by breaking down the oxygen molecules in the air. The electric discharges of the generator will split oxygen into singular molecules where they re-attach to form O3 (if used corona discharge generator).

If using ultraviolet radiation type of generator, then the sun’s UV rays split the oxygen atoms to form O3, which is less applicable to ozone generators. We already know ozone comprises three oxygen atoms, in which oxygen (two atoms) we breathe. The third atom is attached and detaches itself easily and re-attaches to other molecules. This blend with other molecules will result in a chemical reaction. It makes the ozone kill fungus and molds.

How to Safely Use an Ozone Generator?

One has to follow some safety measures while running an ozone generator. If not correctly using the machine, then you and your family members (including pets) are exactly getting at risk. So, to make it use safely without any dangerous threats/risks, you should know how to use this generator safely.

Follow the below mentioned detailed procedure of operating them properly and to prevent causing any harm.

• Ensure that every living thing/being (including people, pets and plants) is out of that room before you turn ON the generator.
• Ozone might damage certain metals and materials like plastic, rubber, artwork and fabrics. So, we suggest you cover or remove anything which is quite significant from the room.
• Avoid re-entering into the room for an hour or two after the generator finished operating. Allow some time to dissipate the ozone gas and to make sure that it is safe to enter into the room.

Drawbacks and Dangers of Using Ozone Generator

However, ozone is a safe component in the high atmosphere, yet becomes a bit dangerous when used in low atmospheres. Here are some points to keep in mind while operating this ozone generator.

• It turns to hydrogen peroxide when it comes to contact with water. The same will happen when it gets contact with the liquid in our nose, eyes and lungs.
• Whenever there is an increase of ozone level in the air, then it results in increasing cardiovascular complications and asthma attacks.
• It makes you sneeze, cough, and feel chest pain when you breathe in ozone for a longer time.
• High exposure to the ozone will develop sensitivities to pollen, molds, and other triggers to allergies. Also, high levels of this ozone might result in reduced immunity and respiratory problems.
• Air cleaners producing ozone can react with other chemicals to create dangerous toxins, which cause irritation to the lungs and result in health issues.
• A study states that different people show different levels of susceptibility when they are exposed to ozone gas. So, it is better to stay away and leave the room when the generator is working or releasing ozone.
