10-Speed Register Booster Fan Fits 4"x10", Smart Vents Thermostat and Remote Control for Home Heating and Cooling

We have a 2 story house and my kids rooms are on the second floor and they constantly complain how warm it is in the summer in their rooms. We have the air conditioning on 66 downstairs and it’s 80 in their rooms. We put these vents in and they work great! They are basically just a fan in the vent that pushes the air into the room. Simple idea but great solution that works surprisingly well. The only downside is the cord is hard to hide (see picture) and the remotes don’t work well but we just put these vent fan in on high and are set and don’t even need to use the remote. There’s also buttons directly on the fan you can use to control the vent fan. Highly recommend.

Put this in a friend's kids room. The room only has one vent which is under her bed and had a air diverter to help push the air out. Her room was a bit muggy and about 6 degrees warmer than the rest of the house. After the quick easy installation, I put the diverter back over it. Within 30mins the room was nearly the same temp as the rest of the house. The remote is extremely helpful as the vent booster is under a twin sized bed. Been about a week and the kid is genuinely still beyond elated about her room being cooler now. Their house's duct work was poorly DIY'd by the previous owner, so the booster is really saving them. Legit can't recommend this enough.

It doesn't seem to pull the cool air up as I expected it would. The fans are always going and on high setting. They are a little loud but it is understandable.

Great register. Easy to install and worked great. My room was hot all the time and after installing this 10 min later the room was colder than it’s been since I moved in. Wish I would have pitched this years ago. Can’t live without it.

I love these they work so well im gonna order more 1 for each room.

The size fits our floor vent perfectly, and I had it up and running in just a few minutes. It has a clean, modern look and blends into the room really well without standing out. We’ve been using it in an upstairs bedroom that usually gets stuffy on hot afternoons, and the difference is pretty noticeable. The room feels a lot more comfortable now. This has always been one of those areas in our home where the heating and cooling is uneven, so this fan has really helped make the temperature feel more balanced and comfortable throughout the day. In terms of noise level, it runs quietly on lower settings, which is great for a bedroom or home office. Even at higher speeds, the noise is still reasonable and not distracting. The airflow is strong enough to actually push air through the vent and make a difference in the room temperature without feeling overwhelming.

I installed this register booster fan earlier today, and the whole process was to be pretty simple. I didn’t need any special tools, and the size lined up well with the opening in my wall. But I still remind to check the opening sites in advance. The remote responds quickly, and the fan runs quietly once it’s on, so it doesn’t draw attention while I’m working or relaxing. I can feel the air moving more evenly around the room with it, and the AC seems to cool the space faster than before. With summer coming up, adding this booster feels like a practical upgrade.

I installed this register booster fan in a 4” x 10” floor vent. It fit the register opening properly and the setup was straightforward. The fan helps move airflow from the existing HVAC system into the room. It runs quietly at lower speeds, with more noticeable sound at higher settings, but still within a reasonable range for everyday use. Airflow distribution in the room feels more even after installation. The multiple fan speeds make it easy to adjust based on room conditions, and the remote control is convenient for changing settings like speed, mode, and timer. It also includes a sleep mode and timer options, which are useful for nighttime use. Installation was simple, and everything fit as expected.
