Important information
With an evaporator, humidification can take a bit longer than it does when
using a nebuliser or vaporiser. So Karl / Karl big takes a while to achieve a
measurable humidification result. If you are operating the evaporator in a
very dry environment, we recommend that you operate the device on level 5
(hygrostat) and at least level 3 (humidification level) for the first few days to
allow the humidity to rise effectively.
