Greenairy claims plant towers halve office VOCs

Greenairy claims its smart plant towers cut daily average and peak VOCs — volatile organic compounds, pollutants — by 50% during regular office hours. Testing used RESET-certified monitors and was validated by TÜV SÜD, the startup says. It uses bio-filtration to break down toxic gases. It ran short-term pilots in Singapore and will appear in TechCrunch Disrupt's Startup Battlefield 200.
