Nevertheless, not all the products in the market are worthy. You need to do a proper testing before choosing any one of them. We know its impossible for you and that is why we have done it. Furthermore, for choosing a product you should also know your requirements. And if you are unsure how to know about it go through our buying guide. It has all the prime considerations that will help you jot down the factors that you need to consider before buying a ozone generator.
1. Ozone Output
This is the most important factor to look for. The better the ozone output the better its efficiency and the faster it will work. With this number you can check how much ozone will be delivered by the unit in an hour. These rating are measured in milligrams per hour. All the products comes with a certain output range and is generally written in their features list. A unit that has 3500-10000mg/h is recommended. Nevertheless, the range also resonate with the area of your space. For example, if you have a large area then you need a good ozone output and if you have a small area you can even manage with lesser ozone output. In our comparison table, we have mentioned the ozone output of all the selected generators.
2. Air purification technologies
Ozone is an efficient gas. It can remove odor and purify the air from allergens, molds, mildews, bacteria’s, germs, virus, and other microorganisms. Several ozone generators comes with a variety of filter to remove odor and allergens from the air. Each filter has its own purpose. Some remove air borne pollutants, some remove microorganisms, and some remove odor. A best quality ozone generator will have the following filter:
- HEPA filter – It traps 99.97% of particles from the air, including dust, dirt and mold spores.
- Air ionizer – It combats against allergens, germs, virus, bacteria and more.
- UV-C light – It kills germs and other microorganisms.

3. Construction
This is another factor to consider to rule out the quality of the box. It is basically the unit housing. A lot of brands comes up with stainless steel devices and other comes up with aluminum or low grade plastic devices. The plastic ozone generators are never recommended as they are not at all durable and efficient. If you are thinking of buying a ozone generator prefer getting a stainless steel or maximum aluminum body one. They are a bit expensive but are sure to last for years.
4. Timer
You cannot be in the same room where the ozone generator is active. You need to shut if off so, the timer ones are always better. They shut on their own once the process is done. So, you don’t need to go inside the room to close it. For commercial large spaces up to 12 hours timers units are best. And for houses or small commercial space a unit with a maximum timer of 2 hours is preferable.
5. Ozone Control
This is another important aspect. Ozone generators that have a control that allow you to send them at a desired ozone level are recommended. It is because they allow you to set the ozone output level as per the requirement. For an extremely smelly room you need to set the output at high level and for a little smelly room, a moderate or low ozone output would do a good job. This way you will en up saving energy and time.
6. Price
This is again a personal choice. An ozone generator is a costly investment. You can not simply picking anyone and that they vary in prices. You get the budget-friendly and the high end models both. So, first you should allot a budget. Needless to say, it is an indirect investment to health so spending a bit more will save in the longer run. Our product list has a variety of options from low, to medium, to high. All of them work great irrespective of their price.
How Do Ozone Generator Work?
Ozone generators produce ozone that attaches itself to dust, dirt, and the smelly particles from the air. The ozone gas is good when its found in the higher layers but when it goes to the lower atmosphere it becomes unstable. These generator makes ozone by breaking down the oxygen molecules from air. This is done by UV reaction or silent corona discharge. The oxygen molecules are split in to single oxygen atoms and then they reattach to form ozone molecule.
The ozone gas has three oxygen atoms and the oxygen has two oxygen atoms. The, last atom is loosely attached and so attaches and reattaches from the environment as per the availability. The combination with other molecules results in a chemical reaction and this further helps in killing molds and fungus. Often, it also results in formation of by products like water and carbon dioxide. The ozone is introduced in the room for an extended period of time. This gives the ozone time to kill the germs and other harmful substances from the air.
