HVAC Ionizer Reviews

HEPA vs Ionizers

HEPA vs Ionizers. Many air purifiers today come with ionizers, and while these features help to boost a unit’s air filtration rate, they also emit ozone and other chemical by-products. These purifiers have been widely discredited in recent months; Boeing, for example, tested the units and found they did not show “significant disinfection effectiveness,” and scientific studies have failed to find support for claims being made by manufacturers, with one study noting that the emission of ozone has long been known to damage lungs and worsen chronic respiratory diseases. They can also create formaldehyde, a probable carcinogen. 

“In the frenzy, schools are buying technology that academic air-quality experts warn can lull them into a false sense of security or even potentially harm kids,” CNN reported. Many schools abruptly stopped using their ionization purifiers, reports NBC,  with one expert accusing some companies of becoming “COVID-19 snake oil salesmen” who are selling technology known to be flawed, and another California school district engaged in a lawsuit against a company accused of misrepresenting the effectiveness of the units.

According to the Environmental Protection Agency, newer air cleaners that use bipolar ionization are part of an “emerging technology,” where “evidence for safety and effectiveness is less documented.”

The EPA also says these devices have the “potential to generate ozone and other potentially harmful by-products indoors.”
