This is the largest diffuser that I have owned to date, and I mean the water capacity not the overall size of it. I use these practically 24/7. I like them during the days to make my house smell great and at night I use them with relaxing essential oils in to get a better nights sleep. My house seems to be very dry so I love being able to put moisture back in the air. This can be used without essential oils as a humidifier only. The health benefits of essential oils in the air is limitless and far better than over the counter drugs or room aerosol air fresheners.
This is a 700 ml diffuser. It is a cool mist humidifier/diffuser so no need to worry about your children or your pets. It has 3 buttons on the front bottom. The 1st button runs the lights, the 2nd button is for the mister and the last button is the timer. The lights are 7 soft LED colors. You can have them on gradually going through all 7 or you can set it to an individual color of your choice and each color can be brighter or dimmer. This works very nicely as a night light. The mist can be on a high or low setting. The timer can be set for 1 hour, 3 hours, 6 hours or on steady until it runs out of water then it will automatically shut off. Depending on the mist setting this diffuser can run up to 20 hours.
