Thoroughly clean the humidifier weekly. It is recommended that the unit be cleaned more frequently if tap water/hard water is being used. Using hard water in the unit leaves mineral deposits and creates a “white mist”.

Tank cleaning
  1. Fill the water tank 1/3 of the way with clean water and 1 tablespoon of white vinegar. Set aside for 20 minutes, over a sink, and shake the tank every few minutes. DO NOT place the tank on the base or run the unit while cleaning.
  2. Drain and rinse the tank twice with clean water.
  3. Use a soft washcloth to wipe down and dry off the tank.
Base Cleaning
  1. Use a cup to fill the base of the unit with 2 cups of clean water and 1 tablespoon of white vinegar. Set aside for 5 minutes. NEVER submerge or place the base of the unit under running water.
  2. Carefully use the brush (provided) to clean around the nebulizer and loosen any mineral deposit build-up. DO NOT touch the nebulizer with your fingers as any fingerprints or other residue can affect mist output.
  3. Empty the cleaning solution by holding the base from the side where the brush holder is located and having the water run to the opposite end.
  4. Rinse the base twice using by pouring 2 cups of clean water in the base each time.
  5. Wipe the base and outer surfaces with a soft, damp wash cloth.

Perfect Aire recommends distilled water.

Distilled water or filtered water is preferred over tap water. Tap water is not recommended because it will require more frequent cleaning and possibly white minerals/dust being dispersed into the air. Using mineral water, alkaline ionized water, well water, or water from a water purifier can cause mold and bacteria to grow easily, increase the water scale, and cause odors. Tap water is chlorinated, making it difficult for bacteria to grow.

White mist or dust from the humidifier is caused by the minerals found in hard water. This issue can be eliminated by using distilled, filtered, or soft water.

First, check where the unit is leaking from. Is the unit leaking from the tank or the base? Did any water get into the base of the unit while cleaning? If the unit is leaking from the tank, make sure that the tank cap is properly screwed on and secure. Check to see if there are any cracks in the tank. Check that the base is set on a flat, level surface. For detailed troubleshooting please call our US-based customer service team at 844-472-2473, Monday-Friday.

If the base of the unit is overflowing, please check the following:

  • Check that the water tank sitting on the base correctly.
  • Is the water tank cap secure and screwed on correctly?
  • Remove the tank cap, and check that the rubber plug at the center isn’t warped and fully covering the center. With your index finger press the center dowel and spring in, this will lift the rubber plug.

There are a few reasons why the unit may not be producing mist; check the following:

  • Lack of water: Check for enough water in the humidifier's tank. If the water level is low, the humidifier may not be able to produce mist.
  • Dirty humidifier: If the humidifier has not been cleaned for a long time, mineral deposits or mold may have accumulated on the ultrasonic nebulizer or other parts, interfering with the mist production. In this case, try cleaning the humidifier according to the manufacturer's instructions.
  • Faulty ultrasonic nebulizer: The ultrasonic nebulizer is part of the humidifier that creates mist. If it is faulty or damaged, the humidifier may not be able to produce mist. In this case, you may need to replace the nebulizer. The nebulizer should never be touched as oil and dirt from your skin will disrupt the mist producing process.
  • Low humidity: If the air in the room is already very humid, the humidifier may not produce much mist because there is not much moisture left in the air to be absorbed.
  • Faulty humidistat: If your humidifier has a built-in humidistat that controls the humidity level, it may be faulty or not set correctly, causing the humidifier not to produce mist. You can try adjusting the humidistat or contacting the manufacturer for further assistance.

These Perfect Aire models have built-in humidistats:

  • PAU132
  • 1PAU05
  • 1PAU105
  • 1PAE25
  • 1PAEC28

NOTE FOR PAU13 model: Hold the tank over the sink and turn the tank upside down to check for a small metal square on the right side of the water tank. The metal square is a magnet; This needs to be in place so the base knows that the tank is properly attached and it can safely start the fan motor. If you are missing the magnet, please contact us at 844-472-2473 to order a replacement.

If none of these solutions work, you may need to contact our US-based customer service team for additional troubleshooting at 844-472-2473 Monday-Friday.

    An evaporative humidifier uses a moistened wick or filter to evaporate water and add moisture to the air. The human eye cannot see water vapor, but rest assured, your humidifier adds moisture to the air while the fan motor is running. The humidifier’s built-in humidistat, or a separate small humidistat, can monitor humidity levels in the room.
