Abstract (en)
[origin: WO2021004766A1] A pollution mask with a filter and fan monitors a rotation speed of the fan and a pressure between the mask air chamber and the ambient surroundings. Breathing flow volume information is then obtained from these monitored parameters, and breathing flow volume information is provided to a user of the mask. This mask functions both as a pollution mask, and an analysis system from providing breathing flow volume information, for example for personal health and/or fitness monitoring.
