  • About the Company 

    Beginning as a senior design project at Columbia, we’re creating machines that make homes healthier, more comfortable, and more energy efficient. SWERV is reimagining ventilation with products that are so simple to install that homeowners can start improving their indoor air quality in minutes.

    About the Solution

    Most Americans live with inadequate ventilation, trapping CO2, radon, VOCs, mold, and other pollutants indoors, hurting our health. Opening windows works great to improve these issues when the temperature and humidity outside is perfect, but when it’s not, you waste energy, get uncomfortable, can cause mold and property damage. SWERV solves this with a compact system that easily, affordably, and efficiently delivers fresh, filtered air without wasting energy when the heat or AC is on.
