How Humidifiers Work And How To Clean Them
All humidifiers increase the relative humidity in the house. But they differ significantly in appearance, operation, cost and maintenance requirements. You can choose portable units or have one central unit installed in the ductwork of a forced-air heating and cooling system. Evaporative humidifiers are least expensive. They rely on a rotating drum or belt to deliver moisture that is dispersed by a fan. Ultrasonic humidifiers contain a nebulizer that produces mist with high-frequency vibration. Warm-mist humidifiers which are the safest, boil water in a chamber then cool the steam by mixing it with air.
Cleaning A Humidifier
- Most people using a dehumidifier for the first time are surprised at how quickly the water collector tank fills. Check the water level several times a day at first. Don’t be surprised if you have to empty it at least once a day.
- Wash the water colector tank every month with water and a mild detergent then let it dry completely. Clean or replace the air filter located under a grill at the back of the unit, at least monthly as directed in the owner’s manual.
- Once or twice a year vacuum the coils depending on how much the dehumidifier is used. Use a toothbrush and mild detergent to clean the coils, taking care not to bend them. Rinse clean by spraying with water.
