  • Works but loud

    I like the large sized water tank, humidistat and that it is filter-less. Although I haven't double checked it's setting using a separate humidistat, the humidifier appears to work fairly well. Unfortunately this humidifier is quite loud. Luckily I can sleep through most sounds/noises. But, compared to the ultrasonic humidifier it has replaced, this thing is noisy.

  • I cleaned my humidifier because the tank empty was lit (when the tank was full) and now very little mist is coming out the top when it is on the highest setting. Suggestions?

    • Hello tagboys3, we recommend cleaning the transducer, which can be located by referring to the manual. Please contact us if you need any more assistance. Thank you!

  • why does the tank empty light come on and shut the unit off, even when the tank is full

    • Hello silvers5, take the tank out and you will see 2 wing nuts on the top turn them and the back part will lift off then you can clean it with vinegar and water. Please feel free to contact us again with any further questions. Thank you for shopping with us!

  • what is the water capacity that this unit holds?

    • Hello terra1, The Bionaire ultrasonic humidifier uses 1.5 gallon of water. Please feel free to contact us again with any further questions. Thank you for shopping with us!

  • Where do I buy a new filter for the Bionaire Ultrasonic humidifier?

    • Thank you for shopping with us cjleslie12. This model does not use a filter. Have a great day.

  • Is this warm & cool mist. Does it have an ionizer or any other parts that have to be replaced? Does it leave a white mist on furniture etc. HOW QUITE IS IT!!!!!

    • According to the product reviews the humidifier is quiet, requires frequent cleaning, and there is no information provided regarding the temperature of the mist.

    • This unit is very quiet. There aren't any parts that need replacing, though cleaning for optimal humidity mist is required. If you use heavy tap water it will put the minerals in the air which will deposit on furniture. With regular house cleaning you won't notice. The temperature of the mist is dependent on the temperature of the water you put in. It does not heat the water before diffusing it to the air.
