Grounded in Science
At WattAir, we turn the world’s biggest challenge, the link between water and energy, into an opportunity.
Our technology captures moisture from air and uses low-grade heat to deliver clean water and efficient cooling anywhere.
From air to potable water
10x Faster uptake
Lower energy. Lower cost.
Air
We pull in moisture at humidities starting at 15%
Heat
Once our system saturates with moisture, we apply low great heat for controlled release of vapor for water production.
Water
The higher temperature vapor is condensed and collected as on site potable water.
WattAir turns atmospheric moisture and low-grade heat into on-site water and cooling — no grid, no trucks, no waste.
