Airtomo / Air Purification System


Our battle with air pollution is not just above ground, it is also under. In fact, pollution on underground transportation can be 20 times higher than roadside air. Inspired by how Nature uses rain to clean the air, Airtomo infrastructure modules and wearables release dry, atomised water vapour to remove particulate matter (PM) through a process called aggregation. Water droplets envelop harmful particles to form large and heavy aggregates which fall to the ground, thus removing PM from the air. They no longer resuspend, even after water has evaporated, and can be removed with a mop or broom after.
