​#1: Everlasting Comfort Ultrasonic Cool Mist Humidifier

​Editor's Rating:

​​4.0 / 5

Are you in search of an extremely effective evaporative diffuser-humidifier? Are you looking for something that requires less frequent refilling and cleaning for large rooms needing more moisture?

Then, we  highly recommend the Everlasting Comfort Ultrasonic Cool Mist Humidifier (6L).

With a bigger water tank (1.6 gallons) and much higher hourly mist output (up to about 270ml) – compared to that of its competitors, this unit can handle the humidifying job in a room up to 400 square feet in size.

Not to mention the running time of up to 50 hours that saves you from refilling it every single day. As long as you keep it on low, you will have pure, clean, and fresh air to breathe for several days between refills.

What we also like about this product is its oil diffusing chamber which allows you to add your favorite natural essential oils to soothe coughs and throats or stimulate your senses.

Does getting both a cool mist humidifier and an oil diffuser at a budget-friendly price sound appealing?

Were we to talk about a major issue about this device, it would be a hard cleaning job. The 2.75-inch water tank opening makes it a little challenging for those with bigger hands to get in for scrubbing.

​However, the Everlasting Comfort Ultrasonic Cool Mist Humidifier (6L) is the right choice for those with smaller hands or those who don't mind regular cleaning.


  • ​Large capacity vaporizer, perfect for space slightly above average sized
  • ​ ​A blue LED night light for optimum use all day and night
  • ​​Clear atmosphere with fewer bacteria and airborne viruses
  • ​Up to 50 hours operating time
  • ​​Affordable price
  • ​​Electricity-saving


  • ​Cleaning job will be a bit difficult

​#2: LEVOIT 6L B01MYGNGKK Warm and Cool Mist Ultrasonic Humidifier

​Editor's Rating:

​3.9 / 5

Our 2nd pick is the LEVOIT 6L B01MYGNGKK Warm and Cool Mist Ultrasonic Humidifiers, which is in a league of its own. This premium-quality unit is powerful enough to serve large rooms.

This device, which turns up to 1.5 gallons (about 6L) of water into a fine cool and warm mist each day with a super high hourly mist output of up to 500ml, can accommodate rooms as large as 400 square feet.

Now, you can keep it running for about 36 hours on a low setting between refills to prevent winter dryness inside your office or home.

The first feature that makes this model outstanding among a crowd is the accuracy of its humidistat which eliminates the risk of over-humidification.

The moisture level ranges between 1 and 2 percentage points of a humidity sensor. It means that you can customize the desired humidity level without having to worry about water dripping from the ceiling.

What’s also impressive is the leakage-resistant ABS plastic that can decrease water spillage – the trouble that many other models might encounter after such a long time in use.

Like other home appliances, the LEVOIT 6L B01MYGNGKK Warm and Cool Mist Ultrasonic Humidifiers have a fair share of pluses and minuses. However, the former outweighs the latter.

Though we don’t like this moderately-sized cool and warm mist ultrasonic humidifier’s price – which is pretty higher than that of other humidifiers, we know that it offers the best value for your money.


  • ​Run on an ultra-quiet operation
  • ​Come with a 2-year limited warranty
  • ​Save your room from the humidity of rainforest levels
  • ​Design with high-quality materials for added durability


  • ​A little bit more expensive than other models on our list
