Do Ionizers Really Clean the Air? - An Expert's Perspective

Ion generators are often used to clean the air, but do they really work? While they can remove small particles, such as VOCs, they are not effective in reducing VOCs in the air. In addition, they produce ozone, which can be harmful to humans and the environment. Air purifiers and ionizers both clean the air by eliminating allergens and contaminants, but they do so in different ways. According to the Environmental Protection Agency, ionizing air purifiers tend to charge small particles better than larger particles.

The issue with ionizers is that they don't completely remove all particles of various sizes from the air. Furthermore, they generate ozone, which can irritate the lungs and cause respiratory problems. While some people with respiratory conditions may benefit from using an ionic air purifier, others may develop additional respiratory issues. Additionally, ionizers do not eliminate odors from the indoor air.

At best, ionizers temporarily deactivate some air contaminants that can be reintroduced into the air if not removed. They work by creating negative ions that adhere to allergens and help impurities settle on the floor. However, they can also produce ozone and other toxic gases that are hazardous to humans and pets. As a result, ionizers may not be as effective in eliminating allergy triggers and asthma.

Air purifiers use specialized filters to trap airborne contaminants of all sizes and completely remove them from your home. The Environmental Protection Agency has no standard way to measure the effectiveness of an ionizing air purifier since it doesn't capture or collect particles like mechanical air filters do. Air ionizers exploit the chemical properties of ions to remove particles and microbes from the air. However, they only remove a much smaller range of particles and may not be as effective as other types of air purifiers.

In addition, a study found that combined air purifier and ionizer devices had an increased cardiovascular risk associated with the ionizer alone. To date, there is no scientific evidence to show that air ionizers eliminate the virus that causes COVID-19. However, there is experimental evidence on the use of high-power ozone generators as disinfectants for some airborne viruses. In conclusion, while air ionizers can reduce some indoor air contaminants, they cannot permanently remove them from the air. They also produce ozone and other toxic gases that are hazardous to humans and pets.

Therefore, it is important to consider all factors before deciding if an air ionizer is best for your needs.
