Operating - Medisana AH 661 Instruction Manual

2.2 Very dry air increases susceptibility to infection and respiratory diseases
Ultra- and leads to fatigue and lack of concentration. Healthy air should have a
sound relative atmospheric humidity of 40 to 55 %. The quiet, energy-saving ultra-
techno-
sound technology of the personal humidifier uses oscillation to convert wa-
logy
ter into a fine mist that increases the moisture level of the air. This improves
the air quality and prevents the mucous membranes and skin from drying
out. The capacity of the device is suitable for a room with a maximum area
of 30 m². Pay special attention to the notes on cleaning and care.
CAUTION
Over-intensive operation can result in saturating the room with
moisture, which can affect the walls, windows and objects in the
room. Therefore, use a hygrometer at regular intervals to check
that the level of relative air humidity does not exceed 55%.

surface which is resistant to water, and that it cannot tip over. In

residues may be produced. Make sure that the mist being issued is
