COSTWAY Ultrasonic 4/5L humidifier.
I’ve tried many humidifiers over the years. Some work well, while others didn’t work as well. I was tempt to search for a humidifier with smart features that adapts to all environments, as there is more technology on the market.
COSTWAY has many humidifiers in different sizes, but I chose the COSTWAY Ultrasonic Cool and Warm Mist Humidifier 4.5L. Here is my review.
Technology
This ultrasonic humidifier has many advance technological features. Smart humidity sensing is the first technology feature. The humidifier detects humidity levels and adjusts to maintain the desire temperature. It stops when the humidity drops to the desire level.
Along with the remote control, the humidifier has an LED touch screen and remote control. You have many options with the LED touch display, such as a timer and mist volume. To access these functions, you can also use the remote control.

The Key Features
This humidifier has many cool features that make it superior to any other humidifiers. COSTWAY has both warm and cold humidification modes that can be use to seed the mist temperature according to your requirements.
Cool mist, for example, can make a living space more comfortable and improve sleep quality. Warm mist is use to cool the room and keep it warm during colder months. You can also use the 360-degree mistnozzle to cover a larger area. You can also adjust the mist volume between low, medium and high.
The humidifier can be set to mute so that it doesn’t make any noise and the humidity is still effective. There is also an aromatherapy box. To enhance the effects of the humidifier, you can place a few drops of essential oil in the box.
What I like and what could be better
It has many certifications including ETL, CE CB, EMC ROHS, and UL. This means that it is safer than other ultrasonic humidifiers. The water tank has a large capacity of 1.2 gallons (4.5 Liters).
Thanks to its air filter functions, the humidifier helps to reduce dust. The humidifier is durable and looks great. It can be used in any room you place it in. It also has anti-skid protection at the bottom to protect it from being scratched.
I think they should improve their user guide. It should be clearer about how to use the humidifier. If you are using aromatherapy, it is best to use it sparingly. The scent can be difficult to get rid of if you change the essential oil. It might be easier to get rid of the smell.
In the Box
The ultrasonic humidifier also comes with a remote controller and a guide. COSTWAY offers a warranty of 90 days.
Where to Buy
