work from home for over 9 hours a day and I'm using this ventilation booster fan to improve airflow in my office and I'm very happy with the results. Installation was very easy and it fits perfectly into the existing floor vents. There's very little noise, basically a low hum that quickly fades into the background. I especially appreciate the built-in thermostat and adjustable fan speed, which allows me to adjust the airflow based on the season and comfort level. The air deflector is now working properly as well. I haven't had it for long but this device has really made a difference.

I'm very happy with my purchase of the 4x10 Booster Fan. It fits perfectly on my vents and has significantly increased airflow for both cooling and heating. The smart controls are great - I love being able to adjust the 10 speeds and temperature with the remote. The built-in thermostat works great, and the fan is surprisingly quiet even at higher speeds. It feels solid, well made, and was a breeze to install. It really improved comfort in a room that was previously difficult to adjust. Highly recommended!

Love it. Great power, easy installation, and perfect for our shed. Great choice!

Absolutely love this booster fan. Easy to install, runs quietly, and does a great job of evenly cooling my room. The remote and digital display are super convenient. Highly recommend.

My upstairs bedroom is always 4-5 degrees warmer than the first floor (where I have the thermostat). When I turn the temperature up or down, the bedroom gets comfortable, but the living room gets very hot or very cold (depending on if the heat or air conditioning is on). I've been using this in my bedroom for the past few days and it has helped reduce the temperature difference to almost 2 degrees. It's easy to use and the included remote is a bonus. I used the auto mode and it wasn't hard to set up. The only thing I wish they would improve on is offering color options.
