Specific effects may include throat irritation, cough, chest pain and shortness of breath, as well as an increased risk of respiratory infections. Some ozone air purifiers are manufactured with an ion generator, sometimes called an ionizer, in the same unit. You can also purchase ionizers as separate units. VOCs are considered indoor pollutants and can cause health problems.
Unfortunately, ionizers are ineffective in reducing VOCs in the air. Because ionizers remove some types of airborne particles, they have also been marketed as methods of reducing asthma symptoms. However, ionizers can worsen asthma symptoms in two ways. Small particles charged by ionizers, instead of being collected, are sometimes left suspended in the air, which can aggravate asthma symptoms.
Second, ionization can generate ozone as a by-product, which can worsen symptoms of asthma and other respiratory problems. Air purifiers using HEPA filters are preferred to ionizers, since they effectively remove particles from the air without presenting any ozone hazard. Ozone has chemical properties that allow it to react with organic materials both outside and inside the body, which has harmful health consequences. Ozone, if inhaled even in small quantities, can be harmful to the health of lung tissues.
In addition, it can cause throat irritation, chest pain, cough, and shortness of breath. It can also worsen other chronic respiratory ailments such as asthma and, in addition, affect the body's ability to fight respiratory infections. When exposed to high amounts of ozone or continuously exposed to low amounts of ozone, not only people with respiratory problems, but also healthy people, suffer from shortness of breath. Although recovering from the health effects of low ozone levels may be possible, it is quite difficult if the damage occurs due to regular exposure to large amounts of ozone.
Users should understand that ozone is a toxic gas and can cause irrecoverable harm to health. Ozone, according to the EPA, can cause harmful health consequences, such as chest pain, cough, shortness of breath, and throat irritation. As more information is disseminated and presented to the public about the dangers of air ionizers, the more informed consumers will be before purchasing an air purifier, and they are likely to be aware of and avoid these potentially hazardous ionizing air systems. If you've come this far and digested all the information about air ionizers (whether they're marketed as ionic air purifiers or ionizers), you've probably already realized that most people shouldn't buy an air purifier with an ionizing function.
Chamber and field tests found that an ionizing device led to a decrease in some volatile organic compounds (VOC), including xylenes, but to an increase in others, oxygenated VOCs more prominently (for example, laboratory tests were performed with air sampling of particles and gases in a large semi-furnished chamber and in a field test with an ionizer device installed in an air handling unit serving an occupied office building.
