Where tap water can go

HumidifierVerdict: YES, WITH LIMITSYes, if the humidifier’s manual allows tap water. Use distilled or demineralized water for ultrasonic and impeller models, especially with hard water or visible white dust. Evaporative and warm-mist units generally release fewer minerals into the air, but tap water can still leave scale inside. If you cannot identify the type, use distilled water.
