How We Rated the Generators

The market is stuffed with so many types of ozone-generating systems, that finding the right one for your home is almost impossible unless you know what to look for. There are a few things to consider when making a purchase and in the following lines, you will discover the importance of certain features and settings.

  • HEPA Filter

  • HEPA filters are able to eliminate at least 99.97% of particles of 0.3 microns from the air. We agree that these “high-efficiency particulate air” filters can be more expensive than other filters, but they perform better with both smaller and larger particles. Since most home appliances are equipped with HEPA filters, you may think that there is are no problems related to their performance. Therefore, before making a purchase, make sure you take a look at the serial number printed on true and absolute filters. Some filters can resemble HEPA filters a lot, but they do not meet the same standards. In simple terms, they are not as efficient as true or absolute HEPA filters.

  • Area Coverage

  • The size of the area that a generator can cover is one of the most important factors to consider when making a purchase. The size of a generator is strongly related to the size of a contaminated area, therefore it is extremely important to know the size of the area that you want to purify. Otherwise, one could buy a device that cannot be used for a particular room size. For example, a small device cannot be used to purify large space because it won’t be very efficient.

  • Timer Function

  • The timer function is another interesting feature that a quality ozone-generating system should have. A timer helps customize the operational flow, which means that your device will not be running more than necessary. Also, a timer function will help reduce your energy bills, so a generator that features a timer is surely an option worth taking into consideration.

  • UV-C Lamp

  • UV-C ozone-generating systems provide an increased level of disinfection, being extremely efficient in killing bacteria, viruses, germs and other microorganisms. These germicidal lamps are usually used in the room air sterilization. Being more than a disinfectant, the UV-C lamps are also capable of reducing dissolved ozone gas distributed in the room air. The most interesting thing about these lamps is that they provide the best sterilization possible without the addition of chemicals.

  • Warranty

  • Another feature that makes quite a difference between a model and another is the warranty length. The period of time for which a model is covered by the manufacturer with a warranty is an important factor to consider as it provides a promise from the manufacturer that certain conditions including the quality of a product will be met.

Things to Consider Before Buying an Ozone Air Purifier

Ozone-generating systems are more versatile and energy efficient than other sanitation systems. They are effective in disinfection but they also happen to be extremely efficient in odor elimination. As mentioned above, there are so many types and models of generators on the market, that it can be quite difficult to make the right purchase. Therefore, if you are looking for a generator to purify the air in your room, it is important to know several things.

  • Ozone output

  • One of the most important spec to look into is the ozone output of the generator. This spec will help you understand how much ozone is delivered by the unit. The rating is generally measured in milligrams per hour. All these information are usually provided by the manufacturer. However, if the unit’s output is not listed, it’s recommended to opt for another unit as that one may have the output levels too low.

  • Air purification technologies

  • Ozone is extremely efficient but not by itself. It can only purify the air and eliminate odors. It doesn’t work against airborne allergens. This is why some systems use HEPA filters and activated carbon filters in addition to ozone air purification. Each method has its own purpose. Some air purification technologies remove pollutants that the others don’t’ eliminate. In order to better understand the purpose of each method, take a look below.

  • HEPA filter – It is able to trap 99.97% of particles from the air, including dust, dirt and mold spores.
  • Air ionizer – It fights against allergens, germs, bacteria and more.
  • UV-C light – It destroys germs, bacteria and other microorganisms.
  • Activated carbon filter – It eliminated odors, chemicals and gases.
  • Programmable Ozone – It eliminates bad smells and sanitizes the filters.
  • Unit housing

  • Another important factor to discuss is the unit’s housing. While some brands spend a lot of money on stainless steel devices, other opt for plastic cabinets which are less expensive but also less durable. Therefore, if you are thinking about buying a generator for your home, make sure you choose a model with a stainless steel housing. It is a bit more expensive than you might think, but it is more durable and chemically resistant as well.

The Ozone is one of the most powerful sterilizers in the world. It is extremely effective at removing microorganisms such as bacteria, viruses, germs and even odors. There are many ozone-generating systems on the market so it is a bit difficult to find exactly what you need. However, in order to find one that is appropriate for you, it is recommended to compare various models. While some models are equipped with many features, others lack certain features. Also, it is very important to learn how to use the appliance. According to several specialists, too much ozone may be hurting your health, that’s why you need to be fully informed on their proper use.
