Too high level of moisture in the air can harm your living space by causing mold and mildew. On the other hand, low level of moisture can also create respiratory problems which directly affect to your family’s health. Hence, keeping an appropriate humidity level in anytime, anywhere is a serious issue for families which have children, especially babies. The most effective solution, in my opinion, is purchasing a humidifier, such as Optimus U-31001.
However, almost all models of humidifier in the market now are used for family’s common space like kitchen and living room. They are too noise in operating and too big to install in private space such as bedroom. And if you have not found your desire humidifier, let take a look at Optimus U-31001 1.5-gallon cool mist ultrasonic humidifier.
Pros of this Cool Mist Ultrasonic Humidifier
This one is the most quiet humidifier model I have ever used. All of the dehumidify operations are running based on a technology called Ultrasonic. This technology helps the device operate in a very low-noise level. You can’t hear even a little sound sending from the device because people simply can’t hear ultrasonic.
Therefore it is very suitable to add moisture to your bedroom, especially in your baby’s room without disturbing the sleep.
This product is a portable humidifier, so we also need to concern about its maneuver ability. With a 2.5-kilogram-weight and an included top handle, you will find it very easy to bring the device to anywhere you want to maintain desire humidity level
The unit is a single room humidifier type, especially optimizing for small room which has space under 400 sq. ft. Hence, its capacity is just acceptable. It can supply nearly 1.5 gallons, about 12 pints, of moisture to the installed space in less than 18 hours, not bad for a small portable humidifier like this one.
You also do not need to worry about the energy efficiency. Although this device still has not earned Energy Star certificate but I can assure that you nearly won’t notice any change in your electrical bill because of its modest power.
Our Rating: 4.1 / 5
Instead of equipping an electronic control, the control panel of this unit just has a single traditional knob. The manufacturer seems to be smart to combine power control and humidify speed adjustment into one knob. This simplify makes the device have a very convenient and friendly user interface. You just need to set your appropriate humidity level and the device will automatically operate until reaching the desire humidity level.
In addition, the reservoir is empty or the power is cut. The knob-kind control panel also makes this device become more durable than the electronic ones because of its simple structure.
Other interesting features
This unit also contains some other interesting features that I want to mention. There is an automatic shut-down system which can force the device to turn off when the water is empty one more feature is a refill indicator light, which will inform whenever you need to add more water to the reservoir.
The included water tank is also very easy to access and empty so you won’t have any difficulty difficult when doing this job.
Cons of Optimus Humidifier U-31001
Every coin has two sides and this humidifier also has its own weakness:
- The first one comes from the ultrasonic technology. Because of not using heat-coil like dehumidifier to provide warm output air, the device just supplies cool mist to the air so that you can’t use it during cold weather while in some place the moist level is very low in winter time.
- The second weakness is not having automatic restart system function so you need to supervise this device more often, especially if the place where you live has some problem with power outage.
In general, the Optimus U-31001 1.5-gallon cool mist ultrasonic humidifier is not the best humidifier among single room portable ones. The device shows some serious weakness which can make you a little hesitate when deciding to buy. However, if you just want to find a humidifier which suit for your baby room, or simply do not wake you up because of some kind of bubbling or gurgling sound, this is the best choice for you.
