SeeBrees HEPA Filtered Face Shield

SeeBrees set out to create a smarter face shield that not only blocked particulates but actively filtered air through a fan-powered HEPA system, with added ionization and wireless control. The goal was to deliver reliable protection with superior comfort and user control, especially in high-risk or polluted environments. We developed a complete embedded solution, featuring two custom PCBs: one dedicated to fan and ionization control, and the other for battery management with USB-C charging and LED status indicators. The fan unit, powered by an ESP32, allowed for wireless adjustments via a cross-platform Flutter app. Users could control fan speed, toggle ionization, and monitor battery status, all through their mobile device. The firmware included power-saving features to ensure all-day use, while the modular hardware design made the product both sleek and manufacturable. This next-gen PPE product bridged the gap between personal comfort, safety, and smart tech.

The final product offered a portable, intelligent air-filtration experience with intuitive mobile control. It improved user comfort and protection in travel, medical, and urban settings, setting a new benchmark for smart wearable PPE.
