Due to its 12-hour operating system, it can provide you with all the conditions that you need to enjoy a good sleep. Although it includes an overheat protection, you need to make sure that your kids don’t get too close to the machine because the steam can be very powerful and it can cause burns.

  • Features an ion exchange filter that helps release pollution-free mist back into the air, making your living environment safer to be in.

However, although its price is a very good one and it is indeed feature-rich, the replacement filters are very expensive, which is a considerable downside. Another flaw is that you cannot opt for a specific humidity percentage with it as it doesn’t future an indicator.


Compared with other similar products, it can deliver a high performance while providing a quiet operation, so you don’t have to worry about the noise that it makes. Moreover, it can be used even if you have small children in the house because the warm mist has the ability to purify air and destroy the existing bacteria. It covers an area of 500 square feet, which is more than enough to ensure proper humidity levels in any space you desire. With it, you can get an output of 2.5 gallons every 24-hours, efficiency being one of its strong points. However, if your room is smaller than 500 square feet, you must set the steam output on low, because too much moisture can gather in places where you don’t want it to. Furthermore, it can transform into mildew or mold that can cause many health problems, like asthma or breathing illnesses.


  • Provides up to 12 hours of continuous use on a full tank.
  • Delivers an optimal performance when placed in rooms of spaces of up to 500 square feet.
  • High 2.5-gallon moisture output per day ensures a quick fixing of existing humidity issues.
  • Ensures cleaner air indoors due to the ion exchange filter it features.
  • Water tank has a generous 4-liter capacity, ensuring you won’t be refilling it too often.
