• The fans are controlled according to demand (i.e. concentration of pollutants in the air) in order
to consume less energy.

• The data of all the filter columns are transmitted via a cloud connection where it is processed
and evaluated. Each user (i.e. designated city officials and MANN+HUMMEL project team) will
be able to upload his or her data and can access a combined database via web applications that
provides accurate real-time data on pollution levels.

• In general, the intelligent systems will be able to provide a self-regulating swarm intelligence that
can control the operation of the systems based on factors such as time of day, noise acceptance,
weather, or actual levels of pollution. The prediction of maintenance and service requirements
is also simplified by the use of intelligent technology, as it makes it easier to estimate when the
filter element needs to be replaced.
