PureStream Portable Water Purifier
A team of four environmental engineers from the University of Toronto launched a reward-based campaign for a portable water purification device designed for camping, emergency preparedness, and international travel. The device used a multi-stage filtration system combined with UV sterilization, targeting outdoor enthusiasts and humanitarian organizations. The team spent four months building an email list of 6,200 subscribers before launching, conducting demonstrations at outdoor trade shows across Ontario and posting educational content about water safety on social media channels.
