It’s simple to use just open the refil pads included in the pack ( has 5 refil pads that last up to 8 hours per pad ) then insert the pad into the slot using the foil to hold the pad. I use my finger tip in pushing it into the slot.
Then plug it in and a nightlight will be activated at night.
Allow 60-90 minutes for vapour to fill the room. I plug ours in the hallway as the room is on the left and right of it and just leave both doors open. The vapour has a blend aromatic oil including lavender, chamomile, menthol, camphor and eucalyptus.
