- A new study finds most air-cleaning technologies lack real-world testing on humans and their potential risks are not fully understood.
- Researchers analyzed nearly 700 studies from 1929 to 2024, finding only 9% examined whether these technologies reduce illness in humans.
- Most studies focused on indirect measurements like tracer gases or dust particles rather than actual viruses or bacteria.
- Concerns were raised about harmful byproducts such as ozone, which can irritate lungs and worsen respiratory conditions.
- Researchers call for new studies in real-world settings, tracking actual infections and assessing side effects, cost, and accessibility.
- Recommendations include choosing independently tested technologies and avoiding products that produce harmful byproducts like ozone.
- Improving ventilation, opening windows, and regular cleaning remain effective ways to keep indoor spaces healthier.
