First of all, you should always try to remove the sources of odors or pollutants as much as possible. Second, you should try ventilating the area to allow for better air circulation in your home, if possible. You may want to disregard this step if you live near a source of high-level outdoor pollution or outdoor air quality is poor.
Afterward, using an air purifier that is not an ozone generator could be a good option to try. There are different types of air purifiers out there, from mechanical filters like HEPA that only remove particles from the air, or gas-phase filters like carbon filters that are only designed to remove VOCs.
If you would like a more complete solution for cleaning the air, you might consider the Molekule technology , which is highly effective against mold, VOCs, allergens like pollen, bacteria, and viruses.
Additionally, if you are especially concerned about odors, there are other, much safer ways to make your room smell fresh. The negative aspects of ozone generators definitely outweigh any potential positive benefits, and it is best if you consider safer and more effective solutions for improving your indoor air quality. Manufacturers of ozone generators often make false claims about their devices and say they are effective at odor removal.
In general, there is no scientific evidence that ozone generators are effective, unless they produce extremely high levels of ozone. Ultimately, there are much more efficient, safer solutions to air quality problems. You can provide a safe space with clean, fresh air for you and your family through other methods including source control, ventilation, and using other air purifier options. Air Quality.
Air Purifier Technology. Inside Molekule. Buy Now. By Sonia Easaw, M. February 25, Reviewed by Dr. Contents What is ozone? Is ozone bad for you? What are ozone generators? How do ozone generators work? Why are ozone generators used to purify the air? Two atoms of oxygen form the basic oxygen molecule — the oxygen we breathe that is essential to life. The third oxygen atom can detach from the ozone molecule, and re-attach to molecules of other substances, thereby altering their chemical composition.
The same properties that allow high concentrations of ozone to react with organic matter outside the body give it the ability to react with similar organic matter that makes up the body, and potentially cause harmful health consequences. When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections.
People vary widely in their susceptibility to ozone. Healthy people, as well as those with respiratory difficulty can experience breathing problems with exposure to ozone. Exercise during exposure to ozone causes a greater amount of ozone to be inhaled, and increases the risk of harmful respiratory effects. Recovery from the harmful effects can occur following short-term exposure to low levels of ozone, but health effects may become more damaging and recovery less certain at higher levels or from longer exposures US EPA, a, b.
Available scientific evidence shows that at concentrations that do not exceed public health standards, ozone has little potential to remove indoor contaminants. First, a review of scientific research shows that for many of the chemicals found in indoor environments the reaction process with ozone may take months or years Boeniger, Second, for many chemicals with which ozone does readily react, the reaction can form a variety of harmful or irritating by-products Weschler et al.
Are the European PM10 thresholds respected in Belgium? What share of particulate matter in Belgium originates from abroad? Is domestic heating an emission source of particulate matter?
Are dust filters for cars an efficient way of reducing particulate matter pollution? Are diesel cars the only polluters? When do smog episodes arise? What measures against smog episodes are taken in Belgium? What can the population do in occurrance of peak concentrations of PM? What can I do myself to reduce PM emission? What is the influence of climate on particulate matter?
What is the influence of particulate matter on the climate? Why are the target values of the WHO stricter than the European limits? Is going for a run in the city dangerous? What is the danger of NO2? How can it make you sick? Elevated exposures to ozone can cause permanent lung damage, and repeated exposure can even increase the risk of dying among persons already in poor health. Persons especially vulnerable to health problems from breathing ozone include children and those who already suffer from asthma or other respiratory diseases, including the elderly.
There are many experimental studies on animals, including dogs, cats, hamsters and guinea pigs, that show respiratory effects from exposure to ozone. Birds are especially sensitive to the effects of air pollutants, including ozone. The unfortunate answer is that misleading advertising by manufacturers is very effective, and no government agency has the authority to fully regulate these devices.
Thus, CARB is actively working to educate professionals and the public about the dangers of using ozone generators. CARB strongly advises against the use of ozone generators in spaces occupied by people or animals.
Other governmental agencies agree with this advice. CARB provides a list of potentially hazardous ozone generators sold as "air purifiers" , which is periodically updated. If an ozone generator is not on this list, it does not mean that it is safe for use. Prior to purchasing an air cleaner, consumers are encouraged to eliminate or reduce indoor pollution sources and to ventilate areas with outdoor air. The most effective method of controlling indoor air pollution is through prevention: eliminating pollution at its source.
To minimize the release of pollutants indoors:.
