In 2016, Unicef reported that 300 million children were living in areas with the highest recorded levels of toxic air pollution. Woobi Play is an ultra-protective anti-pollution mask for kids that uses the same HEPA filter solution as in professional industrial masks, filtering at least 95% of airborne particulate matter. Designed to meet kids at eye level with a playful, educational approach, Woobi Play’s characteristic asymmetric design DNA and translucent, medical-grade silicone structure achieves high-performance protection while remaining sensitive to the social needs of its users. It comes disassembled and with a manual, encouraging kids to put the parts together themselves. This helps them to understand the product’s functionality and encourages a dialogue on pollution between kids and caregivers. The different coloured parts simplify communication around the product, and also allow kids to customise the mask, giving them a sense of ownership and autonomy over their own safety.
