    Check the filters for cleanliness. In fact, in some cases the units are only switched on in ventilation mode long before the first start-up. This causes the filters to become dirty. The Mr. Slim units and the s-AIRME-G02/G07 unit must be properly positioned according to the instructions given in the respective manuals.
