Why We Like It – Cool Mist Humidifier Filterless Humidifier

Cool Mist Humidifiers are some of the best filterless humidifiers around right now. With 400 square feet of room coverage the warm mist output will liven up any large room and keep it feeling fresh. Add a 2 litre water tank to this equation and you can get a full days worth of clean air.

  • Automatic Waterless Shut Off
  • Soft Blue Night Light
  • Quiet
  • Said to Cause White Dust if Not Kept Clean
  • Small Water Tank Capacity
  • Not compatible with essential oils


Cool Mist Filter Free Humidifiers contain an auto shut off when the water level gets low. An important feature that saves the unit from overheating, damage to you or your baby, and unneeded power usage that results in a higher utility bill. It has a large room coverage and can humidify a room up to 400 square feet. It has a long runtime of 30 hours, which is always a plus. But if you do your own filterless humidifier reviews and find you want something longer, opt for the Homech Cool Mist Humidifier.


The Cool Mist Humidifier features a 0.5 gallon tank/2 litre tank. Not exactly known for its large tank capacity, check out the SUNLUNA SL AH001 Ultrasonic Humidifier Operation for something larger. The Cool Mist Humidifier also comes with a soft blue night light that ensures your baby isn’t aroused from sleep during the night. The removable mist nozzle and silencer make the unit easy to clean. And you must make sure you’re cleaning it regularly as some customers have reported white dust clinging to furniture and electronics in the room.


The Cool Mist Ultrasonic Humidifier prefers you use distilled water vs tap water. But it also comes with a timer and humidity control for the humidity level so you don’t accidentally leave it on all night and wake up to a fog. The noise level is rated at 30db, ensuring a very quiet operation, If you want a humidifier that’s even quieter, consider Levoit Humidifiers. I would love to tell you what type of x-year warranty the unit has, but you would have to contact the manufacturer for that. At least according to Amazon.

Cool Mist Humidifier Filterless Humidifier Wrap Up

The biggest drawback to the Cool Mist Humidifier is the white dust it produces when not kept absolutely clean. White dust on your walls and electronics is not a pleasant site when you wake up. But overall, it’s a good humidifier that will give 30 hours worth of freshness for an affordable price.
