For humidifier owners in areas with hard water, filters with white mineral build-up may be cleaned instead of replaced. Filters can be cleaned by soaking for 20 minutes in a solution of 8 ounces of undiluted white vinegar and 1 gallon of water. After soaking, filters should be rinsed multiple times in water and drip dried before being returned to the humidifier. The frequency of cleaning, and the time between filter replacements, varies depending on water quality.Learn more about Heating & Cooling
