VIVOHOME Register Booster Fan - 4'' x 12'' Opening with Adjustable Louver
This VIVOHOME register booster fan is designed for homeowners who want to balance room temperatures without cranking up the HVAC. Think of it as a targeted solution for that one room that's always too hot or cold, like a sun-baked home office or a drafty basement bedroom.
Instead of just moving air, it thinks for you. The built-in thermostat triggers the fan only when the vent temperature hits your preset, so it's not running unnecessarily. After the AC cycles off, you can set it to 'fan only' mode to keep air circulating—helpful for stuffy rooms. The 10-speed EC motor is surprisingly quiet (under 18 dB), so you won't hear it during a conference call or while sleeping.
The WiFi app gives you control from anywhere: adjust speed, set a schedule, or review temperature history to optimize comfort. Adjustable louvers let you direct airflow where needed, and the auto-swing option covers the whole room. Even if the power goes out, your settings are remembered. This isn't just a fan—it's a smarter way to even out your home's climate.
