The combination of a pre-filter, a HEPA, and a PCO filter ensures the maximum rate in removing particles as small as 0.2 microns. Hence, it can retain microscopic pollutants that you never knew existed in the breathing air but were guilty of the poor air quality. Eventually, you will get to breathe fresh air, free of fumes, dust, dander, perfume scents, or VOC. Aside from the air, the ozone sanitizes pollution embedded in all surfaces in your house, including ceilings, walls, floors, and more.

While it’s recommended for domestic use, this model is so powerful that it can even handle large spaces like warehouses, halls, or garages measuring up to 3,500 sq. ft. It has multiple speed settings for the fan and purifier so it can be adjusted to deliver the optimal results depending on the level of contamination or room size.

How We Rated

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 can 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 the particular room size. As such, a small device cannot be used to purify a large space because it won’t be very efficient.

• Timer Function

  The timer 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 normally used in 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 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

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 specs 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 this information is 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 purpose. Some air purification technologies remove pollutants that the others don’t’ eliminate. To better understand the purpose of each method, take a look below.

• HEPA filter – It can 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, others opt for plastic cabinets that 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 stainless steel housing. It is a bit more expensive than you might think, but it is more durable and chemically resistant as well.

The Main Operating Principle

The chemical formula of ozone is O3, also known as trioxygen, a powerful oxidant with a strong smell, similar to chlorine. It is used as an industrial gas transported in different containers. It cannot be transported into a metal container as it oxidizes, so the most recommended types of containers are made of titanium, aluminum, stainless steel, glass, and polymers.

Ozone producers are commonly used to cleanse indoor air and some models can even treat water. Their main objective is to remove nasty odors from vintage clothes, cigarette smoke, fungus, mold, and more. Generally speaking, they work in two ways, the first being silent corona discharge and the other one using ultraviolet radiation. According to specialists, the first method produces more ozone and it is more efficient than UV radiation.

The particles of ozone released into the air catch the impurities and take them down so that the air remaining is fresher, cleaner, and free of any unpleasant smell.

The topics with ozone are a bit sensitive and controversial. Although they are highly efficient in killing dangerous bacteria from hospitals or detoxifying waste, their constant operating in a small space can cause some serious health problems. According to every manufacturer’s specs, ozone producers are safe and don’t affect your health, but the truth is that extended exposure can irritate the respiratory system. The only way to prevent any health hazards is to use them only in unhabituated rooms.
