due to the huge noise level I do not recommend
probably really effective - within a couple of hours the water tank was half full
the mobile app works (you can turn it off and on remotely)
VOLUME - the description states 37db, which is completely misleading. Measured on the phone - dehumidification noise reaches 48 db and at this noise level you REALLY don't want to be in the same room with the machine on
sleep mode just means the display goes off, but otherwise the device is still very noisy
Cannot use the dehumidification and independent air cleaning functions at the same time
