What does an Ozone Generator do?
An ozone generator is a device designed to produce the gas ozone. Ozone is used effectively in water purification, but ozone in the air must reach high levels to remove air pollutants. Health experts warn that it is important to control conditions to ensure that no person or pet becomes exposed to high levels of ozone.
What are the benefits of an ozone generator?
Through this process, ozone generators can be extremely useful for cleaning pungent odors, removing the smell of smoke, and eliminating mold. They are used in hospitals, hotels, and even homes, but, as we'll learn, they can be dangerous and must be used only by trained, qualified professionals.
Is an ozone generator harmful?
What are some of the health effects of exposure to ozone? Adults and children who breathe high levels of ozone for a short period of time (minutes or hours) can experience eye, nose, and throat irritation, shortness of breath, chest pain, and coughing. Breathing high levels of ozone can worsen asthma symptoms.
How long should you run an ozone generator in a room?
Depending on the size of the room, the ozone generator should run for at least 3 to 10 hours. For a whole house, at least 25-30 hours of continuous operation is required to eliminate the majority of pollutants.
What are Ozone Generator air cleaners?
Indoor "air purifiers" or air cleaners that intentionally emit ozone are often called “ozone generators." Manufacturers sometimes inappropriately refer to ozone as “activated oxygen,” “super oxygenated” or “energized oxygen,” which implies that ozone is a healthy kind of oxygen. Because ozone reacts with other molecules, manufacturers claim that the ozone produced by these devices can purify the air and remove airborne particles, chemicals, mold, viruses, bacteria, and odors. However, ozone is only partially effective at cleaning the air when it is used at extremely high, unsafe levels that pose a serious health risk.
Air cleaners that utilize ionizers and electrostatic precipitators are other types of devices that emit ozone but do so as a by-product of their design and function. These devices are designed to electrically charge particles in the air and cause them to attach to surfaces in the room, such as walls or floors. Ozone is released through the charging process, although these devices typically emit much less ozone than ozone generators.
Air purifier and an ozone generator which one is better?
The differences, in fact, are immense. In most cases, air purifiers generally do not release pollution into the air. While ozone generators release a gas that is considered a pollutant to clean and sanitize, air purifiers simply filter the air.
People with asthma should steer clear of anything that generates ozone output. The chemical composition of ozone has been proven to leave behind dangerous byproducts which can act as a lung irritant, so an ozone generator is not ideal. Air purifiers, however, have an excellent track record and follow public health standards. They’re also endorsed by several foundations and federal agencies for reducing harmful levels of particulate matter in your household.
The Advantages and Disadvantages of the Ozone-generating Air Cleaner
Some devices are marketed with advertising claims that they will kill viruses, bacteria, mold, and other biological contaminants, and remove chemical contaminants and odors. However, when ozone concentrations are below health standards, it does not effectively remove biological contaminants. Ozone also does not remove particles (e.g. dust and pollen) from the air, including the particles responsible for most allergies. Ozone generated by air purifiers does little to remove chemical pollutants. In fact, ozone has been found to react with existing chemicals in the air to create additional toxic pollutants, most notably formaldehyde and ultrafine particles.
Some consumers purchase air purifiers to eradicate odors. There is scientific evidence that ozone concentrations below health standards are not effective in removing many odor-causing chemicals. Ozone is also known to deaden one’s sense of smell. Not only does this disguise rather than eliminate odors, but it can also have the dangerous effect of decreasing a person’s ability to detect high ozone levels. Unlike the situation in the air, ozone can be used successfully to purify water in some applications. This is because high levels of ozone can be used in the water, most of the ozone reacts in the water, and people typically are not present when the ozone is used.
Advantages of the Ozone-generating Air Cleaner
Ozone May Reduce Immune System As Well
As if directly causing long-term health issues wasn’t enough, there is now mounting evidence that ozone exposure may also reduce the strength of our immune systems, leaving us more vulnerable to disease and infection. One of the hazards of ozone exposure is a decrease in the body’s ability to fight respiratory disease. There is strong evidence that indicates people with prolonged ozone exposure are less physically equipped to deal with health conditions in the lungs caused by bacteria or viruses.
A 2007 study from the Duke University Medical Center showed that breathing ozone inhibited the early immune systems in lab mice. They exposed mice to approximate levels of ozone that would be considered unhealthy for humans. Essentially, researchers found that mice exposed to ozone were more susceptible to bacterial toxins.
Ozone's Affect On Allergies And Asthma
While ozone can have harmful effects on many people, it appears that people with asthma and allergies can be particularly at risk. People who suffer from asthma have problems with restricting airways, which are aggravated by outside contaminants. Asthma can cause swelling inside the airways, a restricting motion from muscles surrounding the airways, or a buildup of mucus in the pipes. Ozone is a problem for people with asthma for two important reasons.
First, smaller levels of ozone will affect their lungs. Levels that may seem inconsequential to the rest of us can cause breathing problems for people with asthma.
Disadvantages of the Ozone-generating Air Cleaner
These are the main reasons that people choose to release ozone chemicals into their homes, businesses, and property.
Killing Mold and Mildew
Using ozone air purification to “blast” or “shock” mold and mildew is a common commercial practice. Airborne mold spores can be harmful to health, especially to the lungs and respiratory system. Mold and mildew can trigger asthma and allergies, so removing them is always a top priority. However, mold removal often requires the removal and demolition of building materials, including wood framing, sheetrock, carpet, and ceiling panels. With ozone generators, mold can be removed in a relatively quick and affordable fashion.
Removing Bacteria, Germs, and Viruses
Disease-causing substances like bacteria, germs, and viruses are often hiding in plain sight. Places like the kitchen sink, bathroom floor, TV remote, and even salt and pepper shakers can all hold bacteria and germs, increasing the likelihood of sickness in your home. Ozone generators, however, have proven abilities to remove many disease-causing substances by attacking the contaminants at the molecular level.
Removing Odors
One of the most common uses for ozone generators is the removal of odors. In the same way that it attacks mold or bacteria cells, ozone gas will also attack the physical airborne cells that make odors. This can be useful for many different purposes, including hotel rooms that have lingering smells from tobacco smoke. Another potential use is by landlords who need to remove the smell of pets from their properties, or by average homeowners who simply want to remove a foul odor in their home. Using ozone gas is often a last-ditch effort to remove an odor. When other techniques, such as cleaning solutions and scented air fresheners fail, having ozone concentrations can be used to “shock” the room.
What are some of the health effects of exposure to ozone?
Adults and children who breathe high levels of ozone for a short period of time (minutes or hours) can experience eye, nose, and throat irritation, shortness of breath, chest pain, and coughing. Breathing high levels of ozone can worsen asthma symptoms. Breathing ozone for a short period of time may worsen symptoms in people with heart disease. Ozone can react with other chemicals in the air to produce additional chemicals and fine particles that can also be irritating to the eyes, nose, throat, and lungs.
Children who breathe ozone for long periods of time (years) may suffer permanent lung damage, but this health effect is less certain. Some information suggests that children who participate in outdoor sports in areas of high ozone levels have an increased chance of developing asthma.
What alternate actions can I take to minimize indoor air pollutants and avoid using an ozone air cleaner?
Reduce or eliminate the indoor use and storage of odorous products and chemicals
Keep your household clean
Do not smoke indoors
Reduce or eliminate the use of candles
Move activities that generate pollutants outdoors or to an area with proper ventilation
Increase ventilation
Upgrade furnace and air conditioning system filters to higher efficiency
Control excessive moisture and leaks to avoid mold growth.
Consider using stand-alone portable filtration units and adsorbent filters (charcoal and/or zeolite)
Air Purifiers Meaning
Even basic kinds of air purifiers are fantastic for trapping harmful airborne particles, including mold spores, dust particles, and pet dander. They don’t produce harmful ozone levels and can be safely relied upon to trap any biological contaminants, including those that act as lung irritants. The American Lung Association holds air purifiers in high regard when it comes to controlling long-term health issues such as asthma. Conventional wisdom tells you just to open a window, but that’s no longer your best bet. If you’re curious why check out air purifiers vs open windows to learn more.
