What could be the reason the light is illuminated but the device isn't functioning? The new filter is dry when first utilized. If used immediately, it may lead to slow water absorption and a lag in mist output. By soaking it in clean water, the filter fibers can expand completely, creating water-absorption channels that promote effective mist generation. Please note, dear customer, that your humidifier filter must be soaked prior to its first use to ensure it works properly!
