Should I Buy an Air Purifier with an Ionizer?

When it comes to air purification, ionizers are often marketed under a variety of names, such as “ionic air purifiers”, “negative ion air purifiers”, “air ionizers” and “bipolar needle-tip ionization”. If you're considering buying an ionizer to reopen your business during the COVID pandemic, it's best to consider it part of a larger air purification system. A review of scientific studies conducted on air purifiers revealed that most air ionizers have no noticeable effect on particle levels. The ionizing function of air purifiers releases negative ions into the environment, which attract and trap positively charged ions that carry allergens and bacteria.

With the addition of the ionizer function, this device cleanses the air while releasing negative ions, which enhances indoor air quality. Nevertheless, there are some very convincing reasons why you should get an air purifier with an ionizer feature. By contrast, air ionizers (also known as ionic air purifiers, ion generators, or simply ionizers) don't capture anything. Unlike many purifier companies, Smart Air does not use ionizers in its purifiers to achieve its high CADR rates, only safe and effective HEPA filters.

On the other hand, through electrical charging, air ionizers temporarily deposit some air pollutants on surfaces. Although the use of air ionizers can cause a temporary but significant reduction in certain types of air pollutants, the production of ozone and other toxic gases caused by the normal operation of these devices does not usually cause any general change or even an increase in certain air pollutants, such as ozone, oxygenated volatile organic chemicals (VOCs), and toluene. Most major air purifier companies use ionizers in their air purifiers, including Xiaomi, Blueair, Levoit, and many more. These devices produce ozone indirectly, but they can still emit a large amount of ozone, especially compared to other standard appliances.

Smart Air is a certified B corporation founded by Thomas Talhelm, a professor at the University of Chicago and a fan of clean air. If you're looking for an effective way to improve your indoor air quality without compromising your health or safety, then an air purifier with an ionizer is definitely worth considering.
