How Do Ozone Producing Devices Work?

Mostly used in industrial and medical applications, systems that generate ozone have been seen as quite controversial for residential use due to their powerful operation. It is the DNA of ozone itself that brought so much attention to this subject, being composed of three atoms of oxygen unlike the air we breathe which has only two atoms. Ozone can be produced through one of two methods – either ultraviolet or corona discharge.

Ultraviolet light creates it at the moment when a 254-nanometer wavelength hits the oxygen atom, causing the molecule to split into two atoms. When the atoms combine with another oxygen molecule, ozone is produced. Through the corona discharge method, ozone is created by applying a high voltage to a metallic grid which is stuck between dielectrics. The voltage produced by the dielectric and a grounded screen creates the ozone from the oxygen present in that environment.

Making Up Your Mind the Right Way – What to Look for in an Ozone Generating System

Without a doubt, it is your main target to pick a quality system which generates ozone as it’s in your best interest to not end up spending money on a faulty product or one that performs poorly. In the following, we will provide you with the needed help to make a right choice by showing exactly what you should look into while analyzing your best ozone generator option.

  • Ozone output: The first spec to look into is the ozone output of the system as, after all, this is its main purpose – generating ozone. The rating for the ozone output of the device is measured in milligrams per seconds. To find out what is the production rate of a certain model, check out its spec sheet. If this information is not provided by the manufacturer, stay away from the product as it means that the ozone output of the device is actually between dangerous parameters.
  • Air filtration media: Seeing how it is an air quality boosting device, it should come with a filtration media which help eliminate certain airborne pollutants that ozone cannot handle. We recommend you look into a product which comes with an activated carbon filter media, for example, as it endorses the destruction of dust, pollen, and a lot of other contaminants.
  • Housing quality: While not the most important spec to look into, it is still smart to check what the housing is made from. Otherwise, you risk spending your money on a product that will become faulty at the slightest hit. No one is perfect and you could inevitably hit it or throw something on the generator, depending on where you store it, so it is smarter to make sure it can handle a beating.
  • Warranty: Obviously, as with any product out there, you must look into the warranty that it is covered by as this is one of the best indicators of its overall quality. A top-tier system will be backed by a lengthy warranty, indicating that the manufacturing company trusts the quality of the product it distributes. Furthermore, the longer the warranty, the less likely it is to end up having to spend money out of your own pocket on repairing it in case it becomes faulty.

How We Rated Our Top Picks

Picking the best products on a competitive market is never easy, so we had to establish certain criteria prior to starting our tests. While we tested and analyzed different products on this market, we made sure to check and compare some important elements, specs, and features that we consider to have the biggest effect on the quality of the device. Check out our ratings and find out what products received most points from the following matrix:

Rating Criteria How It Affects Performance Product to Receive the Best Score
Area Coverage
The size of the area the ozone producing device can cover indicates in what type of space you can use it. This is one of the specs we strongly recommend you closely look into in order to avoid purchasing a system which will underperform in the area you intend to place it in or one that is oversized for your needs. We gave a better rating to the products which cover bigger areas as they are more versatile to work with and offer a much powerful overall operation.
Green Air Purifiers GAP-400, Green Air Purifiers SFA 2.2, Breathe Fresh Air Simply Fresh
Ozone Generation
The performance of an ozone generator is best described by its ozone generation rate, so it is easy to see why this was an important rating and ranking criteria for us. Obviously, the bigger the ozone production rate is, the better, so most points went to the product which complied best from this point of view.
OdorStop OS2500UV
HEPA Filtration
For a filter to qualify for the HEPA rating, it must remove at least 99.97% of particles as small as 0.3 microns from the air. This makes HEPA the most prolific types of filters, by far. Thus, it is obvious why we gave a higher approval rate to the ozone devices which featured a HEPA filter.
Green Air Purifiers GAP-400, Breathe Fresh Air Simply Fresh
Timer Function
Another feature that makes quite a difference in the overall performance of the device is the presence of the timer function as it allows you to customize the operational flow. Therefore, you will not have to keep the generator running for more than you consider it to be necessary, and you will end up paying less when the energy bills come as a result.

Energy Consumption
The amount of energy consumed by the device when it runs is another important element to take into consideration when ranking an ozone generating system as it shows if running it will spruce up the electricity bill too much. Evidently, the product to receive the best rating when it came down to this criteria was the product that boasted the best energy efficiency.
OdorStop OS2500UV
Warranty Length
The period of time for which the device is backed by the manufacturer with a warranty is the final rating element which greatly affected our ranking as it shows how qualitative the product is and how much trust the producing company puts in it.

Frequently Asked Questions


?What is ozone?
Ozone, or known for those who like to dabble in chemistry as O3, contains three atoms of oxygen as opposed to the two atoms we breathe under normal circumstances. Due to its content, it is the second best sterilizer in the world, being capable of killing strong odors, bacteria, and viruses.

?Is ozone safe for my health?
Although you might find on the internet sources which slander ozone generating devices, the premises on which their accusations are founded are completely false. The reason why we are confident about this statement and why we consider ozone safe for human health is because it has even been awarded by the American Food and Drug Administration for its safety.

?If I use the ozone generating system, will the unpleasant odor come back?
When you utilize a normal air purifier with odor-reducing filtration media, the unpleasant smell will be atoned, but the source of the problem won’t go away. Thus, your problem won’t actually be fixed. However, with an ozone generating system, the source of the odor will be destroyed, so the odor will be an issue of the past.
