Many people struggle when going out in the rain because they want to wear a face mask to protect their face from getting wet, but this often fogs up their glasses or even their helmet visor. This seemingly minor issue has been resolved thanks to a mask called "FlowMask," which intelligently directs airflow, allowing for clear vision in humid and rainy environments.
The product was invented by three students: Tran Cong Hieu, Truong Khoi Nguyen, and Nguyen Pham Thuy Vy, all K24 students from the Faculty of International Business and Management at VNUK. The project impressed the competition judges with its practical approach to solving the problem of fogging caused by condensation, a major inconvenience for mask wearers, by improving the airflow structure to prevent moisture from adhering to the lenses. FlowMask has redefined the concept of the conventional mask, transforming it into a strategic product with great potential and versatile applications in daily life.
Student Tran Cong Hieu, the team leader of the invention, said that the mask is made of waterproof parachute fabric with a layer of flexible plastic underneath. During the competition, the students received feedback and experimented with several alternative materials to create a more comfortable feel for the user.
Before embarking on the design process, the research team examined N95 masks with one-way valves that offered the best anti-fogging properties for glasses, as well as those with a snug fit using memory foam, high-quality cloth masks, and even water-repellent sprays. The results showed that these solutions only provided short-term relief.
“Most face masks on the market use aluminum nose clips, but these never fit snugly around the nose 100%, leaving marks and causing pain. FlowMask solves this problem completely with memory foam padding that can remember the shape of the face, creating an absolute seal as well as a breath-directing mechanism for complete ventilation and no condensation, suitable for all weather conditions,” Hieu emphasized.
After the competition, the students will continue to refine the product to provide the best user experience, and also hope to attract investment from companies to bring FlowMask to market. According to the invention team, instead of using disposable masks, FlowMask can be used for 6 months at an estimated price of 75,000 VND per mask.
Truong Khoi Nguyen jokingly said, "Actually, we're not selling masks, we're selling 'safety.' This price is only equivalent to a few cups of coffee, but delivery drivers and people wearing glasses can travel with peace of mind regardless of the weather."
Currently, the invention team is finalizing their application to participate in the 8th "Students and Young Entrepreneurs with Startup Ideas" competition organized by the Ministry of Education and Training in April. Simultaneously, the team has been selected to represent Vietnam in the International Innovation and Creativity Award - ICIA 2026. The team has received patent and intellectual property rights for their invention, which helps prevent fogging by allowing airflow and directing breath to avoid condensation inside the mask and instead release it onto the surface of the glasses.
“The team never considered FlowMask as just an exercise to win a competition, but as a real startup. With the patent granted, the team is confident that they will produce a complete face mask and supply it to the market,” said Tran Cong Hieu.
