Cleaning the filters of an air conditioner is an ordinary maintenance operation that can be carried out independently. To be able to operate safely, we recommend that you first turn off the power supply to the machine.
The filters are usually accessed by opening the front door of the indoor unit (depending on the models); once reached, they must be removed and taken to a comfortable position to be able to suck up the dust present. Subsequently it is possible to wash them (if of the washable type) with running water at low temperature without the use of solvents. To disinfect the battery, specific spray-type sanitizers are required, capable of eliminating mold, germs and bacteria.
To keep the air conditioner efficient it is necessary to keep the filters clean constantly, sanitizing them at each change of season.
