In 2020, carbon dioxide monitors became a hot commodity as people sought to assess indoor safety amid the pandemic. Researchers in the U.K. discovered that CO2 plays a critical role in determining virus survivability in the air. They developed a groundbreaking technique using piezoelectronics to study this phenomenon and found that pH, not temperature or humidity, is key to viral decay. However, the data sparked controversy among aerosol scientists about the airborne transmission of viruses. Further research revealed that even small increases in CO2 concentration significantly extend the life spans of SARS-CoV-2 variants, emphasizing the need for improved indoor air quality.
