Proof of Usefulness Score
Industry Mainstay

Rensair is a legitimate, venture-backed company (raised ~$7M, acquired AirLabs) offering hospital-grade air purification and HVAC optimization. While the submission itself contained significant inaccuracies (claiming 'everyone' as the audience and 'most people' as users), external verification confirms strong B2B traction with clients like the NHS, Skechers, and schools. The technology is patented and lab-validated. The score reflects the high real-world utility and verified market position, heavily penalized by the poor quality and exaggerated claims of the submission data.
