More features

• Powerful Airflow to Your Bed: More Even Upstairs Comfort: Hot upstairs or stuffy/chilly bed corners? This register booster fan helps push cooled or heated air farther—right where you rest and sleep. With up to 150 CFM and a 95.13° precision-angled air-guide grille designed to help reduce backflow, it sends more air forward for stronger circulation and faster relief. Ideal for kids’ rooms, upstairs bedrooms, and attic/loft spaces—helping the room feel fresher and less stuffy
• SO QUIET YOU'LL FORGET IT'S ON (AS LOW AS 17 dBA): Designed for nurseries and light sleepers, this vent fan booster runs as low as 17 dBA in Sleep Mode, so naps, bedtime stories, and overnight rest stay undisturbed. A three-part quieting system—PWM motor, dual deep-groove ball bearings, and dynamically balanced blades—helps minimize vibration for smoother, quieter airflow. Ideal for kids’ rooms and upstairs bedrooms—so sleep stays deep, calm, and uninterrupted
• SMART TEMPERATURE SENSING—SET IT ONCE, IT RUNS ITSELF: When upstairs swings from stuffy to chilly, you shouldn't have to babysit the fan or keep tapping buttons. Built-in heating/cooling start temps make this register fan plug-and-play—select Heating or Cooling (or set a target temp once). A high-precision NTC sensor near the air intake senses the airflow temperature as it arrives and smoothly auto-adjusts fan speed as conditions change—so your room stays on track day and night
• INSTALLS IN MINUTES—PLUG IN, CLEAN SETUP, NO REMODEL: Place this booster fan into your floor, wall, or ceiling register, then secure it quickly. Designed for 4” x 10” openings only—please measure to confirm fit. The included 100–240V adapter keeps power simple, and the 9.8-ft shielded cord reaches a nearby outlet for clean, neat cord routing. It uses just 6W, so you can run it longer without worrying about your electric bill—ideal for hot upstairs bedrooms and stubborn corners
• 10 SPEEDS—SMOOTH, QUIET CONTROL FROM SOFT TO STRONG: Go from a feather-soft breeze to powerful ventilation, so the airflow always feels right. Keep it ultra-gentle for bedtime, balanced for daily use, or turn it up when the room heats up—then fine-tune with 10 speed levels on this vent fan. Unlike many basic fans with only 2–3 rough settings, PWM control enables smooth ramp-up and ramp-down (no sudden jumps) for a steadier, quieter flow
• SIMPLE CONTROL FROM BED OR HALLWAY—NO APP NEEDED: Use the 26-ft remote to adjust speed, mode, and timer without getting up, or press the 6 physical buttons on the faceplate for quick changes. A clear LED display shows your settings at a glance, and the timer is perfect for naps or bedtime. Built-in memory restores your last setup after a power outage. No Wi-Fi, no apps—just simple, reliable control built into this vent booster fan for the whole family
• WORRY-LESS AROUND KIDS & PETS—BUILT TO HELP PROTECT: In a busy home, little hands and paws find everything. The 5.8 mm anti-finger grille helps keep fingers out while blocking toys, crumbs, and debris from dropping into this air duct booster fan. A reinforced aluminum-alloy faceplate uses 4.7 mm support ribs—thicker than many standard 3 mm designs—for added rigidity, and supports up to 300 lb for everyday foot traffic. 94V-0 flame-rated housing adds extra peace of mind
• PREMIUM FLUSH-MOUNT LOOK—BUILT-IN, NOT BOLTED-ON: Sits flush and stays out of the way—so it won’t stick up, steal space, or look like an add-on. The sleek black anodized aluminum faceplate blends into modern bedrooms and offices for a clean, built-in finish. It secures with two side screws to keep this fan vent booster snug and seamless in the register, while a reinforced frame and rigid blade system deliver steady, reliable performance season after season
