Huge help for second floor airflow!

5 out of 5 stars

Huge help for second floor airflow!
I have a second story bedroom that just doesn’t get the airflow the my first floor gets so I got this to help push it into the room. This was easy to install and start working. I did have to read instructions a couple times understand the auto controls, but once I had it set up it is making a huge difference! It is fairly quiet for a fan. I included a video of the register fan running so you have an idea of the noise it will make.

    Reviewed in the United States on February 6, 2026

    Size: 4" x 10"Verified Purchase

    This small vent fan did not give me much hope but to be honest,it did not disappoint. It is so silent that I hardly know that it is on the lowest gear but it somehow does blow the air out of my vents. I like that it does not blow the hot and cold air, it simply makes the airflow feel natural and refreshing.the perfume dispenser is so pleasant. I add some drops of my favorite essential oil on the cotton pad and all of a sudden the room smells great. It is as though I had a mini-spa in my living room. The timer is quite convenient. I am able to program it to 1or 3 hours and it automatically switches itself off. I would certainly recommend it.

    Remote controlled Registrar fan

    Reviewed in the United States on October 19, 2025

    Size: 4" x 10"Verified Purchase

    This registrar works good, it does what it’s suppose to do and blow the air out when the Air Conditioner is on. I haven’t tried it with the heat yet. Only thing is I was really needing something that would adjust which way it blows and these don’t have adjustable slats on it. It can be noisy if you have it on too high.

Product Summary: Register Booster Fan Fits 4" x 12" Register Holes, 10-Speed Smart Thermostat AC Vent Fan with Timer Setting and Aroma Function, Air Vents Fans & Heating for Wal

From Estensoe
Automatic Heating Cooling Trigger – Designed for wall or floor mounting, this vent booster fan integrates seamlessly into your HVAC system to efficiently boost airflow. The smart vent fits perfectly into standard 4″ x 12″ vents and can be set up in minutes. Ideal for large rooms, small apartments or any area that needs improved air circulation.
Intelligent Programming – The LCD Smart Controller has a high-precision temperature sensor that triggers the ac vent fan to automatically adjust the airflow intensity based on the temperature you set for the room. Simply set your desired temperature, adjust the vent booster speed (1-10 levels) and switch between modes using the buttons or remote control.
PWM Motor & Energy Saving Operation – Built with durable materials and precision engineering, our register booster fan uses a quiet PWM DC motor for reliable performance and energy efficiency. 18 dBA noise at the lowest speed, the fan boosts airflow without heating or cooling the air itself, making it an eco-friendly choice for your home.
Customizable Aroma Diffuser – Enhance your living space with our innovative fan with scented cotton pads. Simply drop your favourite essential oil into a cotton pad , place it in the diffuser and when the air vent booster fan is running, the room will be filled with fragrance.
Timer setting – Press the remote control for the 2 hour / 4 hour timer function. The fan will automatically stop when the working time is reached if the timer is set.
Smart Temperature-Sensing Operation‌ – Our booster fan intelligently switches on and off based on the duct air temperature. In Summer mode, it activates when the duct temperature falls below your set point (55 – 80°F). In winter mode, it activates when the temperature rises above your set point (70 – 90°F), ensuring optimal comfort all year round.
