Why is there not enough mist coming from my Bionaire BU1400 Humidifier?
- D
  Dr. Micheal FlynnAug 11, 2025
  If your Bionaire Humidifier isn't producing enough mist, it could be due to several reasons. First, check if the Mist Control is set to the 'Lo' setting and adjust it to 'Hi'. Also, the surface where the unit is placed might be causing resonance; try placing it on a steady surface or the ground. Mineral scale buildup on the transducer can also reduce mist; gently clean it with a damp cotton ball, being careful not to apply too much pressure. Finally, ensure the water in the tank is fresh and clean; empty and refill it if it's dirty or stagnant.

  Abnormal noise from your Bionaire Humidifier can be due to a resonance effect caused by too little water in the tank; try refilling the water tank. Alternatively, the surface the unit is on might be causing resonance; place the unit on a steady surface or on the ground.

  If the mist from your Bionaire Humidifier has a bad odor, it might be because the appliance is new. In this case, open the water tank and place the appliance in a cool area for 12 hours. Another reason could be the use of unfiltered or not fresh water. Try washing the tank out or changing the water.
