Thank you for sharing your experience with the Homedics Premium Warm & Cool Mist Ultrasonic Humidifier. We're sorry to hear that the unit began malfunctioning after a few months, especially with the beeping and night light issues. That’s understandably frustrating—especially when it’s not listed in the troubleshooting guide.We recommend double-checking that the top-fill tank and cap are seated securely, as some models can behave erratically if the sensor detects an improper seal. However, since you've already reached out to Homedics without a response, we suggest giving their consumer relations team a call at 1-800-466-3342 for faster assistance.If your purchase is still within Sam’s Club’s return or warranty window, you might also consider returning or exchanging it through them.

Thank you for sharing your experience with the Homedics Premium Warm & Cool Mist Ultrasonic Humidifier.We’re sorry to hear that the product isn’t meeting your expectations. The unit is designed to provide efficient mist dispersion, but we understand that placement and room size can affect its performance. For optimal results, we recommend placing the humidifier on a flat surface, at least 2 feet away from walls, and not directly beneath shelves or ceilings to allow the mist to disperse more evenly throughout the room.
