Over the past few months, a group of committed volunteers from the Philadelphia Makers Meetup have come together to address the shortage of lifesaving face masks. Our objective was to design a practical, DIY device that could sanitize reusable PPE in accord with the following 6 criteria:
Quick, cheap and simple to build – less than 2 days, using around $200 in parts (readily available from Amazon)
No programming or advanced electrical skills required
Reliable, safe and easy to use with low maintenance
Quick operating cycle – 30 minutes at 75C (158F), once the cabinet has warmed to the operating temperature.
High throughput -100+ masks per day with minimal risk of mask damage
