Essential Oil Diffuser, 500ml Ultrasonic Aroma Diffuser with 6 Pure Essential Oil Set, 14 Color Mood Light, Quiet, Timer and Waterless Auto-Off Cool Mist Humidifiers for Home, Office, Study, Yoga, Spa

I bought a humidifier for my daughters bedroom, following advice from the GP (Central heating dries out the air etc) therefore I wanted something quiet to try and avoid disturbing her sleeping. This is really quiet 👍🏼The colours were an added bonus as I didn't necessarily want one with colours, but as it was for my daughter I thought I'd make it "interesting" for her & she enjoys choosing which colour she wants (she prefers one colour rather than the effect that goes through a colour change cycle)👍🏼It's easy to use; 3 settings and 2 settings for the colour change 👍🏼It's slightly bigger than I realised... 2.5 litres means it holds a lot of water & therefore isn't ideal for someone planning to have it in a small space. I've had to put it on top of my daughters wardrobe rather than the top of the bookshelf as initially planned.I haven't tried to clean it yet, but it did occur to me after first use that it would probably be better to use filtered water, simply because we live in an area with very hard water & limescale builds up heavily & quickly.
