Review on 🌬️ HoMedics Cool Mist Ultrasonic Humidifier with 1.4 Gallon Tank, 65 Hour Runtime, Nightlight, Auto Shut-Off, Clean Tank Technology, and BONUS DEMINERALIZATION CARTRIDGE by Kristi Crooks

A warning to anyone who encounters a "marginal fault" or code 33 or 13 on your oven. These ultrasonic humidifiers atomize airborne mineral deposits, which are drawn into the return air that feeds your oven. Your oven filter will catch all the limescale build up and eventually clog in two weeks or less. This will disable the "high limit" sensor on your stove to prevent cracking of the heat exchanger due to excessive heat. This is because the oven cannot extract enough "cold/cold” air from the recirculation ducts due to a clogged filter. Even using one of these humidifiers in an upstairs bedroom if it has an air return duct is enough to clog your furnace filter. The humidifier itself works great but if I could return it I would because of the issue I explained above.
