8 Important Considerations Before Making a Purchase

Before delving into the factors to consider, it is essential to understand what ozone generators are and how they work.

8 Important Considerations Before Making a Purchase

1. Types of Ozone Generators

The following are the types you should know:

Types of Ozone Generators

Ultraviolet Ozone Generators

In this type of generator, ultraviolet light is used to create ozone gas by breaking down oxygen molecules into individual atoms, which then combine with other oxygen atoms to form ozone gas.

These are typically less powerful and less efficient than other types.

Corona Discharge Ozone Generators

The corona discharge ozone generator uses a high-voltage electrical discharge to create ozone by splitting oxygen molecules into individual atoms. The resulting atoms then combine with other oxygen molecules to release ozone gas.

These generators possess more power and efficiency than ultraviolet models.

Cold Plasma Ozone Generators

It uses a high-frequency electrical discharge to create ozone. The electrical discharge occurs in a chamber filled with ambient air, which creates a plasma field that converts oxygen molecules into ozone.

These are usually more expensive than other types. But they produce higher concentrations of ozone and are more durable.

Electrolytic Ozone Generators

A low-voltage electrical current is used to split water molecules into hydrogen and oxygen atoms. The oxygen atoms then combine to form ozone.

Electrolytic ozone generators are often used in water treatment applications.

2. Size and Weight

The size and weight of an ozone generator are important factors to consider depending on the intended use and portability requirements.

  • Smaller and lighter ozone generators are typically easier to move around and are suitable for personal use.
  • Larger and heavier ozone generators are usually more powerful. They are better suited for commercial or industrial use where higher ozone output levels are required.
  • However, larger units may be more difficult to move around and may require more space for storage.
  • The best suitable weight for them is around 6 -8 pounds but this doesn’t mean that the models which exceed this are not good. If you can compromise on weight, a generator like Green Air is a great choice.

3. Ozone Gas Output

Ozone output is an important factor to consider as it determines the amount of ozone that the generator can produce.

  • The ozone output is typically measured in milligrams per hour.
  • The ozone output required will depend on the intended use of the generator.
  • For example, smaller units with lower ozone output may be suitable for home use or for treating small areas. While larger units with higher ozone output may be required for industrial or commercial applications.

It’s important to go with the one that has appropriate ozone output for the intended use. Using a unit with too low or too high ozone output can lead to ineffective ozone treatment or potential safety hazards.

For more insights, I recommend you to read this.

4. Features

Here are some common features to consider:

best ozone genartor Features

Timer

A timer feature allows you to set the duration of the ozone treatment. It is handy for controlling the amount of ozone produced and ensuring safe usage.

Fan

Some ozone generators have a built-in fan that helps to circulate the ozone and distribute it more evenly throughout the room.

Air Filter

An air filter is helpful in removing impurities and particles from the air before the ozone treatment. It improves the overall effectiveness of the treatment.

Automatic Shut-Off

This feature is useful for ensuring safe usage and preventing overexposure to ozone. It turns off the device after a set period of time or when the ozone concentration reaches a certain level.

Adjustable Ozone Output

It allows you to control the amount of ozone produced. This is useful for treating different-sized spaces or for varying levels of ozone treatment.

Remote Control

Some models come with a remote control. It is extremely useful for controlling the ozone treatment from a distance.

5. Portability

Portability is an important factor to consider when selecting an ozone generator, especially if you plan to move it around. Some are designed to be more portable than others, with features such as:

  • A lightweight design,
  • Carrying handles,
  • Compact size.

It’s important to ensure that the selected model is still powerful enough to produce the required ozone output for the intended use.

6. Safety

One question that you must be asking yourself is, can ozone generators be harmful to human health if used improperly? Ozone is harmful to human health when inhaled in high concentrations.

Important! Safety is a critical factor to consider when selecting ozone generators. So it’s important to choose one that includes safety features and adheres to safety standards.

Some safety features to consider include:

  • Automatic shut-off when the ozone concentration reaches a certain level
  • Safety switches to prevent accidental or unauthorized usage
  • Ability to monitor and control the ozone output levels.

It is necessary to follow the manufacturer’s instructions and safety guidelines when using an ozone generator. Having proper ventilation is crucial to avoid potential health risks. It’s also important to avoid using ozone generators in areas where people or pets are present.

7. Maintenance and Operating Costs

Some ozone generators require more frequent maintenance and may have higher operating costs than others. It’s important to consider the cost of replacement parts, such as:

  • Ozone plates
  • Filters
  • The frequency of replacement

Some models might consume more electricity or require more frequent filter changes. It can increase operating costs over time. Considering the ease of maintenance and the availability of replacement parts is also important. Some may require heavy maintenance, while others might not.

8. Warranty

A warranty provides peace of mind and protection against defects or malfunctions in the product. The length and coverage of the warranty can vary between different ozone generator models and manufacturers. Therefore, you should always look at the warranty of every product.

  • The minimum warranty should be 1 year.
  • A 3 to 5-year warranty is also offered by some manufacturers.
Note: It’s also important to consider the manufacturer’s reputation and customer service. It drastically impacts the quality and reliability of the product.
