As an expert in the field of air purification, I have witnessed the growing popularity of ionizers as a solution for indoor air pollution. These devices claim to eliminate harmful particles and improve air quality, but are they truly effective and safe as they claim to be? In this article, I will reveal the downsides of ionizers that you need to know before considering them for your home. According to the Environmental Protection Agency, particles smaller than 2.5 micrometers in diameter, also known as fine particles or PM2.5, pose the greatest health risk. These particles can penetrate deep into the lungs and even reach the bloodstream, causing serious health problems. Exposure to fine particle pollution has been linked to premature death, heart attacks, respiratory issues, and more.

Ion generators
are one type of air purifier that claims to eliminate small particles by charging them and attracting them to surfaces in the room. However, these particles can easily be resuspended in the air through normal activities like walking or cleaning. Some ion generators have a collector to attract charged particles back to the unit, but there is no scientific evidence that they are effective in improving air quality. In addition, ion generators can produce ozone, a lung irritant, both indirectly and directly. While indirect ozone production is a concern, there is even greater concern with direct and deliberate introduction of this harmful substance into indoor air.Despite what some marketers may claim, there is no difference between the ozone found in the open air and the ozone produced by these devices. In fact, under certain conditions, ion generators and other air filters that generate ozone can produce levels of this pulmonary irritant that are much higher than what is considered safe for human health. The Food and Drug Administration may regulate a small percentage of air purifiers that claim to have health benefits as medical devices, setting a limit of 0.05 parts per million of ozone. While ozone can be used to reduce odors and pollutants in unoccupied spaces, the levels needed to achieve this are above what is considered safe for humans. This raises the question: is bipolar ionization, another type of ionizer, a safe and effective solution for homeowners?Bipolar ionization is a technology that releases positively and negatively charged ions into the air to deactivate bacteria and viruses and reduce other air pollutants.
These ions attach to the pollutants and cause them to clump together, making it easier for them to be captured by an air filter. This technology has been used in the healthcare industry for decades, with hospitals like Wray Community District Hospital and Clinic, Johns Hopkins, and Children's Hospital Boston implementing it in their buildings. However, according to the EPA, bipolar ionization is still considered an "emerging technology" with limited research on its safety and efficacy outside of laboratory conditions. While this is common for newer technologies, it also means that there is not enough evidence to fully support its use in homes. This lack of evidence can lead to public distrust in this innovative technology. Therefore, as an expert in this field, I encourage homeowners to do their own research and request test data before considering the use of products with bipolar ionization technology.
At the very least, make sure that any equipment you purchase complies with UL 867 certification for acceptable levels of ozone production, or preferably, UL 2998 certification for zero ozone emission. Sensibo Elements is one example of an air purifier that has been certified by UL 2998 and detects harmful airborne pollutants.
