When it comes to air purification, it's essential to understand the technology being used and how it works. An ionizing air purifier, also known as an ionizer, is different from traditional purifiers with a mechanical filter, such as a HEPA air purifier. Some people believe that air ionizers emit dangerous levels of ozone that can be hazardous to health when inhaled in high enough doses. However, an air ionizer that allows ozone levels to be controlled or that does not produce ozone is perfectly safe. Most major air purifier companies use ionizers in their products, including Xiaomi, Blueair, Levoit, and many more.
Laboratory tests have been conducted to measure the effects of air ionizers on particles and gases in a large semi-furnished chamber. Additionally, a field test was conducted with an ionizing device installed in an air treatment unit that supplied a busy office building. The results of these tests showed that air ionizers can reduce particulate matter concentrations and improve the respiratory health of children aged 11 to 14. However, there is evidence that suggests that ionizers can have an adverse effect on heart rate variability (a measure of cardiovascular health). This means that any benefit to the lungs may come at a cost to the heart.
Unfortunately, despite this knowledge, school districts and airports in the United States have been tricked into disbursing millions to companies that market these harmful products. When considering whether or not an air ionizer is safe for use, it's important to consider the type of device being used. If the device produces ozone, it should be avoided as it can be hazardous to health. However, if the device allows for ozone levels to be controlled or does not produce ozone at all, then it is perfectly safe for use. It's also important to consider the environment in which the device is being used. If the device is being used in a large space such as an office building or school district, then it may be beneficial to install an air purifier with a mechanical filter such as a HEPA filter instead of an ionizer.
This will ensure that particulate matter concentrations are reduced without any potential adverse effects on heart rate variability. Overall, air ionizers are safe for use when used correctly and in the right environment. It's important to understand the technology being used and how it works before making any decisions about purchasing an air purifier.
