Empty your humidifier daily and refill with fresh water.
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.
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.
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.
