Abstract

A pollution mask has a driven fan, wherein a rotation speed of the fan is monitored, as well as the external temperature and optionally also humidity levels. The fan rotation speed or change in fan rotation speed is used to obtain a first value which relates to a depth of breathing and a second value which relates to a rate of breathing. These are used, in combination with the ambient temperature and optionally also the ambient humidity level, to set the fan speed. Thus, the fan speed is set taking into account the breathing characteristics of the user as well as the ambient environmental conditions.

Description

technical field [0001] The present invention relates to an anti-pollution mask for providing filtered air to the wearer of the mask under airflow assisted by a fan. Background technique [0002] The World Health Organization (WHO) estimates that 4 million people die each year from air pollution. Part of this problem is outdoor air quality in cities. The worst in this category are Indian cities such as Delhi, where annual pollution levels exceed recommended levels by 10 times. It is known that Beijing has an annual average of 8.5 times the recommended safety level. However, even in European cities such as London, Paris and Berlin, the stated levels are above the World Health Organization's recommendations. [0003] Since this problem won't improve significantly in the short term, the only way to fix it is to wear a mask that provides cleaner air through filtration. For added comfort and effectiveness, one or two fans can be added to the mask. These fans are switched on d...
