The PureGuardian® Ultrasonic H1250 Humidifier uses a metal diaphragm vibrating at an ultrasonic frequency to create water droplets that are expelled out into the room to help maintain the desired humidity level. An Ultrasonic Humidifier is virtually silent when operating.

It is recommended that you place the product up and not on the floor. Wash out the unit with fresh water using a cleaning brush and soft cloth. Do not use chemicals or detergents. Gently wipe away debris from the filter with a soft cloth. To clean the ultrasonic disks, remove spray spout and use the enclosed cleaning brush to regularly remove build up and spots from this area. White vinegar will help to prevent this build up.

In order to maximize performance, it is recommended the unit be placed at least 2 feet off the floor to give the mist the opportunity to evaporate before hitting the floor and to eliminate the carpeting or wood floor surrounding it from becoming damp.

Please note: The manufacturer recommends the use of distilled water to limit or prevent mineral dust and buildup.

The following situations could contribute to excessive white dust so these steps are recommended to avoid:
  • Using water that has been treated by a water softening system could result in an increased incidence of white dust due to the excess sodium in the softened water. Therefore, it is recommended to use water that bypasses the system, bottled, or distilled water.
  • Use of this product with a negative ionizer air purifier or air cleaner with an optional post ionizing function could contribute to an increased collection of dust on surfaces. If this occurs, try operating this product without the negative ionizer air purifier or with the optional ionizing function on the air cleaner off.
