When your sick, Keep the dial at Medium for relief
May 24, 2018
Cost wise it is quite the bargain. However the downsides on this item is the sensor and design. This model from what I can tell does not have an air escape port like other types. This air port is essential as it allows air to escape from the reservoir in the base. This in turn allows for gravity to release water from the top water container. So, the result is the device converts all the water in the bases reservoir into mist, but the fit is so tight that an air pocket is created thus trapping the water in the top water tank. So the unit believes it is out of water and shuts off. You have to keep an eye on it, and move the tank around to get the water to fall into the base.
Nevertheless, that being said I have found that the vapor lock issue only seems to occur if you set the dial anywhere beyond Medium. So, to keep from having to jiggle the tank, or knocking on the tank to keep it from stopping; just make sure you keep the dial between low and medium. I have tested other humidifiers with a similar design that cost more, and believe me running this unit at medium puts out more than enough vapor. Others put out the same amount of vapor at their highest setting.
So, in summary this is a pretty decent unit for the price. Nevertheless to get around the engineering issues of the until just set your output dial between low to medium and you will be happy at its performance.
I am giving the product 3 stars as it works fine as long as you keep it within the suggested range for output.
I am giving an additional star for the wonderful customer service provided by the seller. They were very responsive and professional.
