Evaporative coolers are commonly associated with
the build-up of mould either in/on ducts/vents or within rooms themselves. To minimise and prevent the formation of
mould here are some tips and recommendations:
run the system with the house/rooms fully ventilated – evaporative systems
are designed to be used with open houses, not closed houses – open windows
and doors when possible.
run the system on ‘cooling’ or ‘water’ options all the time i.e. non-stop
– remember this is putting moisture into the air (the number one cause of
mould) and does not allow the rooms to dry out. When the weather is higher in humidity
this also adds to the moisture in the air. As the day starts to cool off it is recommended to turn the system back to just ‘fan’ so as some of the moisture can be dried out.
3. After using the units on ‘cooling’ or ‘water’ options, before turning the system off it is recommended to run just on ‘fan’ for 15-20mins (approx. time only and may vary according to weather conditions etc). By doing this you are drying out the air ducts and vents and therefore minimising the chance of mould build up.
