Water-Saving Humidifier

Target User

Urban households wanting to save water while improving indoor air quality

Design Goal

Reduce household water waste by integrating rainwater harvesting and greywater reuse into daily humidification systems

Timeline

October 2023 – November 2023 (1 month)

Skills

(Design) Adobe InDesign, Adobe Illustrator, Fusion 360

I designed a modular humidifier that reduces water waste by reusing rainwater and grey water.

The product features a dual intake system, a multi-stage filtration unit (mechanical, activated carbon, UV), and an integrated humidity control valve. It tracks PH, humidity, temperature, and water usage via sensors and external display.

I conducted user interviews, eco-research, and morphological analysis, then built functional requirements and prototypes to validate feasibility. This solution tackles water scarcity through circular resource reuse in everyday life.
