Most humidifiers provide a numerical indicator on the control panel. The Dreo 6L Smart Humidifier does that as wellhowever, it also has a large 4x2" color coded humidity indicator that I can clearly see from across the room. The panel turns colors (shades of orange for dry, green for comfort, and blue for wet) based on the humidity level detected in the room. The whisper-quiet humidifier has a noise level of 28 decibels and a maximum run time of 60 hours. Its also easy to clean, since the six-liter top-fill water tank has a carry handle for easy transport, and the mist pipe is detachable. This humidifier lets me select a warm mist or a cold mist, so I can use it in any seasonand it has a dual aroma pad tray for those who like to use essential oils. The smart humidifier can be connected to Wi-Fi, then controlled via smartphone, and its available in two color choice: silver and white.Best Tower Humidifier: Levoit OasisMist 1000S Smart HumidifierLEVOIT OasisMist 1000S (10L) Smart HumidifierCoverage: 600 square feet | Run time: 100 hours | Size: 10"D x 8.4"W x 28.7"H | Weight: 6.4 lbsOne concern with humidifiers is where to place it.

Functioning as both a warm mist humidifier and a cool mist humidifier to improve your indoor air, you get up to 45 hours before the tank needs to be refilled. The water tank has a spacious opening that is easy to fill, and it also has a handle for easy transport. If you connect the humidifier to the VeSync app, this will allow you to remotely control the device (turning it on and off, changing the mist settings, and scheduling timers). For example, you can schedule it to turn off when you leave for work and then turn back on at 5:00 pm so it'll start misting the air before you return home. You can also add essential oils to the aroma pad to create an essential oil diffuser. The noise level is a low 26dB, and as a tester, I can verify that the noise level is nonexistent.Canopy Humidifier PlusCanopy Humidifier PlusCoverage: 1000 square feet | Run time: 36 hours | Size: 14.5"L x 12"H x 9.5"W | Weight: 6.6 lbs
