Air purification is crucial to reduce airborne contaminants that can trigger numerous respiratory infections or even neurological problems.
There are a few different types of air purifiers, ozone generators being among the most effective options for removing biological contaminants. While ozone generators offer unique benefits, choosing the right one based on your needs is essential.
In this article, you’ll find the top 7 commercial ozone generators, handpicked for their exceptional performance. For anyone who doesn’t have much experience with air purifiers, the article also explains what to consider when shopping for an ozone generator.
5 Factors to Consider When Choosing a Commercial Ozone Generator
There are barely any universal ozone generators that work for every possible scenario. That being said, these air purifier devices should be selected based on specific purposes and applications
The factors you should consider to choose the best commercial ozone generator include its type, size, durability, quality, ozone output, safety features, and any additional characteristics you may benefit from.
So, before we list the best ozone generators you can order online, take a look at the features you should pay attention to when purchasing one.
Ozone Generator Type
First things first, let’s discuss the main types of ozone generators and their features to determine which one would work best for you.
There are four main types of ozone generators. These include:
Corona Discharge Ozone Generators
These devices produce ozone from electrical discharge, also known as spark. The spark splits the oxygen molecule into elemental oxygen, which then binds to another oxygen molecule, forming ozone.
The primary advantages of corona discharge ozone generators are enhanced sustainability, increased ozone production, and cost-effectiveness.
UV Ozone Generators
In nature, ozone is produced from UV light and this technique is widely used for generating ozone for commercial applications. So, in UV ozone generators, an ultraviolet light source is used to produce ozone.
As the amount of ozone produced through this method is significantly low, such generators have limited uses.
Cold Plasma Ozone Generators
These generators use dielectric discharge to create cold plasma. When gaseous oxygen is exposed to cold plasma, it splits into elemental oxygen, which then recombines with other elemental oxygen atoms to form ozone.
Cold plasma ozone generators are beneficial as they provide high ozone performance with low power input required.
Electrolytic Ozone Generators
This type of ozone generator uses electrolytic technology to produce ozone from water rather than gaseous air or oxygen. In the process, water molecules are first split into hydrogen and oxygen molecules, and then oxygen splits into elemental oxygen to form ozone.
Although high-quality electrolytic ozone generators are quite expensive, they offer a broad range of applications, including in pharmaceutical facilities, wastewater treatment, soil purification, and air pollution control.
Ozone output is a mass-over-time value that indicates the amount of ozone in milligrams produced per hour (mg/h). Although rarely, ozone output can also be measured in g/h or lb/day.
In some cases, ozone generators offer a range of ozone output values that you can set manually based on your needs.
When used for commercial or industrial applications, you should ensure that the ozone output is high enough for it to be effective.
However, it’s also worth mentioning that ozone output should be carefully adjusted to avoid the accumulation of unhealthy levels of ozone in the air.
This article explains how to calculate ozone output or measure it using a special ozone measurement device.
Ozone Generator Size
Ozone generators come in several size options to cater to different needs and applications.
When selecting the size of an ozone generator, you should think of the required ozone output, intended uses, and energy consumption.
Larger ozone generators usually have increased production capacity and are suitable for large-scale applications.
On the other hand, small ozone generators are ideal for limited spaces and mobile applications.
In terms of energy consumption, large generators have higher electric power requirements and, therefore, are less energy-efficient and more expensive.
Durability is another factor to keep in mind. In the long term, investing in a durable ozone generator is a better choice as the machine will last longer. That being said, you also save on the installation costs.
In addition, high-quality ozone generators are not only durable but also safer to use since they are designed and assembled based on specific standards.
When buying an ozone generator, you should always pay attention to the safety features.
First, check if the generator has a relevant certification indicating that it meets specific safety standards and comes with detailed user’s manual for additional instructions.
Also pay attention to the casing of an ozone generator. The generator must be enclosed in a way that the risk of accidental contact with electrical components is minimized.
Don’t forget to look for any additional features that would make an ozone generator even safer. It could be ozone output monitoring, integrated timers, automatic turn-off function, ozone concentration management, or airflow adjustment.
