SOME NOTIONS ON
HUMIDITY
Air always contains a certain amount of water in
the form of vapour. This determines the level of
humidity in an atmosphere.
The capacity of the air to hold water vapour
increases with temperature.
This is why in our homes, as soon as the tempe-
rature decreases, the vapour contained in the air
condenses, as is evident on the colder surfaces
in the room, such as the windows, walls etc.
The purpose of a dehumidifier is to remove the
excess moisture from the air, avoiding the dama-
ge caused by condensation.
Experts have established that the optimum envi-
ronmental conditions for our well being and for
the home are obtained between 40% and 60%
relative humidity. Lower relative humidity can be
achieved with higher room temperatures. For
lower room temperatures the achievable relative
humidity will be on the higher side, closer to
60%. Therefore, with lower room temperatures,
you are recommended to heat the room even
minimally.
This considerably increases the dehumidifying
power of the appliance.
With heating, the condensation formed by the
water vapour on windows and other cold surfa-
ces evaporates into the air to be collected by the
dehumidifier.
