Homàsy BNIB Top Fill 4L Color Lights Oil Diffuser Humidifier: We repurchased a second back up. We never ended up opening the second one. I love the top-fill design and the large 4L capacity. This is for a large size room 150-380 sq ft and the mist swivel let’s you move the opening for the mist direction. It’s an easy wipe-down clean with a paper towel, let air dry, and has a touch switch 2 adjustable mist modes and sleep mode, and another touch button for 7-color mood light. You can add your favorite essential oils and the large 4L capacity doesn’t run out during the day or night. The coloring changing light function button is pretty cool too!
