About the company 

Trellis Air is the first to make membrane-based dehumidifiers commercially viable. The company’s goal is to replace desiccant wheels at 80% less energy, replace standalone dehumidifiers at 50% less energy, and eliminate reheat energy from buildings.

About the solution

The principle is a high-function, low-cost membrane plus a novel vacuum pump arrangement. During 2024 the startup built a working 200cfm prototype.
