Clean tank. Clean mist.

Here are some helpful tips for cleaning the Honeywell MistMate Cool Mist Humidifier.

  • Daily

    Empty your humidifier daily and refill with fresh water.

  • Weekly

    Use undiluted white vinegar to remove scale (mineral buildup). Then, if desired, use a solution of 1 teaspoon bleach to 1 gallon of water to disinfect your humidifier.

  • Seasonal

    At the end of the season, or if not using, descale and disinfect your humidifier (as outlined in ‘Weekly’) before storing. Never store humidifier with a used filter or other accessories.

Additional Cleaning Tips

  • Prevent mineral buildup.

    If you have hard water, be sure to check your filter regularly (for evapourative humidifiers) for mineral build up that may reduce output. Filter-free cool mist (Ultrasonic) and warm mist humidifiers should be cleaned regularly to reduce mineral build up on the nebulizer or heating element.

  • Consider humidifier cleaning balls.

    Consider using a humidifier cleaning ball to keep your humidifier cleaner longer between cleanings.

  • Check the manual for instructions.

    Always follow the manufacturer’s instructions for regular cleaning. Download the manual.
