Dryers ensure that wash-resistant micro-organisms do not develop as they reduce the essential ingredient for any organism, namely water, while clothes are also better protected from non-pathogenic micro-organisms that destroy the clothes themselves, such as fungi.

Depending on the energy class to which the clothes dryer belongs, it consumes the corresponding energy. So e.g. a dryer with energy class B can consume up to twice as much energy as one with A+, while the latest A+++ technology saves up to 70%.
