Feel the difference with  a DreamWell™ Humidifier

“Overall performance is 10/10. The sum of all the features makes this really feel like a luxury product. I have honestly never used a product that fits into a space & manages to disappear, yet works in the background flawlessly...”

“The performance is much better than what I have used before. It keeps the room at my desired level of moisture and keeps me from waking up coughing at night.”

“I mean, you have to admit it would look very good in any room, not standing out like a sore thumb like most humidifiers...I super love the fact that I can schedule it to turn on when I’m not home. I have a lot of plants in my home, and they appreciate your machine as well”

    Recurring Leaks and Unreliable Hardware

    I received this machine as a gift and have been using it for approximately one year. Unfortunately, my experience has been marked by significant reliability issues.

    Within the first four months, I had to replace the original unit due to a series of hardware failures, including false alerts, app connectivity issues, and a completely unresponsive control panel. While the manufacturer provided a replacement, this second unit has now developed a concerning flaw.

    Over the last month of using the humidifier function, I have experienced frequent leaking. About once every five times I remove the water tank for refilling, water leaks from the internal housing of the machine onto the floor. I can confirm this is not a result of a spill, as the tank is nearly empty when it is removed. Between the software failures of the first unit and the mechanical leaks of the second, I no longer have confidence in the quality or safety of this product.

    Poor reliability

    In less than a year the water pump module is no longer working. It first started to not recognize when it was filled, but was able to fix that by cleaning the contacts on the pump inside the module. A couple months later, the pump still recognizes when tank is filled but pump motor itself is shorted. I’ve always used filtered water from the refrigerator to fill the unit as well as clean the fill tank periodically to remove any scale. The wick has been replaced once as directed by the app. This is extremely disappointing, especially since no replacement parts are listed / available.

    A great humidifier

    I have been loving this humidifier! The design is beautiful and intuitive, and its so quiet I can’t even hear it at night. I bought one for my baby’s room and one for my partner and I. I can tell it makes a difference in the humidity of the air, and I breathe better because of it. My skin is also happier as well!

    This company sold me a faulty product

    Basin is full and below the max line and yet the humidifier “low water” light comes on every time. I shouldn’t have to troubleshoot a brand new device every night before using. This product hasn’t worked the entire two weeks I’ve had it. I will never purchase another BlueAir item ever again, I believe this item didn’t pass QC (there’s no document to certify it did like with most small appliances)

    Oh and now my order can’t be found via the return system, how convenient….

    Thank you for sharing this feedback. We are sorry to hear about your experience with the InvisibleMist™ Humidifier and the repeated low water alert. This is not the experience we want you to have. To reset the low water light, please fill the reservoir, then press the fan speed button on the unit or in the Blueair app to activate the pump and sensor. The light should turn off once water is detected. We have reached out to you directly to help further and assist with any other requests.
