Best Cool Mist Humidifiers of 2025

"I recently got the AquaOasis humidifier, and it has really exceeded my expectations. From the first use, I noticed a significant difference in air quality at home. Its modern, compact design makes it easy to place anywhere. The large tank capacity allows for hours of use without constant refills. I love that it's ultra-silent, which is perfect for night-time use, and I can easily adjust the humidity level to keep my environment comfortable and healthy."

"Before I settled on a 4-star rating, I thought quite a bit about this humidifier. It does a good job at humidifying smaller spaces, it's quite affordable, and the customer service is very responsive. However, I noticed that all ultrasonic humidifiers tend to just shake water into droplets, which means you should always use distilled water for safety, especially if you have kids or anyone immunocompromised. Keeping it clean is also important; I recommend a thorough weekly clean to avoid any buildup."

"I recently bought the AquaOasis Cool Mist Humidifier, and I am really impressed with how well it works. It has been a game-changer during the dry winter months. Its sleek design fits nicely in my living room, and it operates quietly, which is great for my daily activities and sleep. The 2.8L tank lasts for hours without needing a refill, and the adjustable mist output lets me customize the humidity level. I've felt a significant improvement in air quality, especially with my dry skin and congestion issues."

"As a first-time mom, I wanted to replace my old humidifier with one that was easy to clean. After doing a lot of research, I ultimately chose this Dreo humidifier. I’m really impressed with it! The large tank lasts all night on full power and is also easy to clean. I can scrub it out without any hassle. The only tricky part might be the center column, but I believe it stays clean with proper maintenance. It's also whisper quiet and doesn’t disturb my little one. I’d recommend this to any first-time parents looking for something effective and budget-friendly!"

"Living in the desert, my RV's humidity was at a mere 19%. This humidifier brought it up to 30% in just 2 hours on high! I can feel the difference in my breathing and no more static shocks. The only downside is that the buttons don’t light up, making them hard to see in the dark. Overall, it's a great, quiet option and does the job well!"

I can finally feel safe putting it back in my kid's room without worrying about mold. This would also make a perfect baby shower gift!"

I prefer having humidifiers running at night for my little ones when they're sick; it helps keep their mucus thinned. This model is incredibly quiet and works wonderfully!

The color-changing feature is a delightful bonus; I enjoy using the orange light for warmth at night. After two weeks of continuous use, I’m no longer struggling with dry air. I liked it so much that I ordered a second one!"

"This humidifier has exceeded my expectations! It's compact yet powerful, releasing a lot of moisture. I particularly enjoy the two spouts, allowing for moist air in multiple directions.

"My wife and I live in a 2,000 square foot apartment, and this humidifier works great! It’s much quieter and easier to clean than our previous unit. We can run it full blast for over 15 hours without needing a refill. I’ve found that the so-called 'leaking' is just condensation, which we manage easily."

"Me gustó que dura mucho tiempo, que llegó antes de lo esperado, y que es más grande de lo que imaginé. Lo pedí para ayudar a mi hijo con una tos por asma y ha sido una compra exitosa."

It's relatively quiet too; I keep it on the lowest setting at night, and it doesn't disturb my sleep."

Our home feels fresher and more comfortable since we started using it!"

"I recently purchased the Vicks 3-in-1 SleepyTime Humidifier for my kids' room. It provides a gentle, cool mist that keeps the room comfortably humidified. The built-in night-light is perfect for creating a soothing atmosphere. We also enjoy the essential oil diffuser feature, enhancing bedtime routines. The only tiny downside is that the water tank needs refilling more often if used overnight. Overall, it's easy to clean and lives up to its pediatrician-recommended status!"

"I LOVE this humidifier. I live in the upper Midwest and our winters are so dry. I usually wake up with a sore throat and dry mouth every morning. I've had other humidifiers but there were always issues, like the tank was small and didn't run all night, or it had a light on it that kept me awake, or it was loud, or I had to bring the tank to the sink and fight to unscrew the cap to add water, etc. This humidifier is the BEST. First of all, you add water from the top. You don't need to carry anything to the sink. Just take off the top and refill it. It holds about a gallon of water so you only have to refill every other day or so. There is no light so if you like darkness while sleeping you will appreciate this. It is QUIET. And best of all, it emits a lot of moisture into the air and I never wake up with a sore throat or dry mouth anymore. I've had many humidifiers over the years and this is the best one I've ever had. I hope it lasts a long time. Highly recommend!"

"This humidifier was a good value for the money. The water capacity is enough to last all day, and it is extremely quiet when operating. The simple controls make it easy to use, and the auto shut off is a handy safety feature to have. Its compact size makes it perfect for the small grow tent I am using it in to create a more tropical environment for my plants."
