Signs Of a Silent Killer
IQAir x WHO
Ever feel like screaming into the void? Same.
When northern Thailand choked on the world’s worst smog,
the government just... shrugged. No alerts. No action. 👃🩸
With many living offline, we made the danger visible with OOH billboards that shouted the truth.
💥 Signs Of a Silent Killer 💥
[ Phase 1️⃣ Hook: Choke on the Truth ]
🆘 #1 Bleeding Sign
🆘 #2 (In)visible Sign
🆘 #3 Dirty Mask Sign
👇 OOH Billboard
👇 Social Media Filter
👇 App Icon
[ Phase 2️⃣ Act: Sign for Clean Air ]
Every time signs 🆘 #1, #2, or #3 detect dangerous air, it triggers an auto X post with a #WeNeedCleanAir and real-time PM2.5 patient stats. Anyone can join the movement by posting with the hashtag and signing the petition at weneedcleanair.org.
Each petition signature fills up the special billboards made of real PM2.5 particles.
[ Phase 3️⃣ Strike: Deliver It to Power ]
In Bangkok, the country’s center of power, the iconic Chong Nonsi Skywalk is transformed into a giant lung, displaying real-time air quality data from northern Thailand.
Nosebleed signs take over the Government House and political posters to mirror the hazardous reality up north.
