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

Easy to install. It truly cools off the upstairs loft master bedroom. House is set at 70. Upstairs was 77/78 on hot summer days/nights before. Now room is 72/73. It’s got a nighttime quiet mode, but I actually drop it to that during the day. I prefer the higher fan speed at night as it’s a bit louder (but not super loud) as it drowns out other noises and lulls me to sleep. It’s a well worth it investment if you already have central air and just need that extra air pull from the register. I’m glad I did this first before investing in an AC unit at much higher cost to purchase and run. No difference in my energy bill either. Highly recommend.

I really liked these, until a few weeks in one started making noise. We cleaned it, and jostled it a bit and it stopped, but it became consistent every time we turned it on. Cleaning didn’t help, we basically have to shake it for it to stop and at 3am that’s obnoxious. We got a second one for our kids’ room and it’s never worked properly. We followed all the directions, did our research, and got it working for a few weeks. Now it makes an awful beeping sound, and the electrical isn’t accessible. There is ZERO customer support, only a “try another issue” option on a loop when you say no this didn’t resolve the issue. These are cheap pc fans wired to a register…if I had known I probably would have built one myself. But of course the return window is now closed so I can’t even get any help at all, what a waste of $75

I used one of my bedrooms for my home office before I retired. It was the hottest room in the house. I tried those ice-cooled “air conditioners” but they mostly made me damp. I installed an overhead fan and that helped a lot. But then I came upon this booster fan and all of my problems were solved! I wish I would’ve had this years ago! It definitely pumps up the output of your register, and has settings so you can have just a little boost or max it out so that you feel like you have a you feel like you have an air conditioner right in your room! I use the room now for computer work, Zoom meetings, email, etc. It’s so pleasant in there! Don’t hesitate, buy it!

We have a big upstairs bedroom that the house system does not adequately cool in the summer. With one of these on each of the two floor vents, the temp in the room is reduced about 2 degrees. So, they are not miracle workers, but they do help. They noticeably improve air circulation in the room. Hopefully, they will prove to be long lasting... we've only had them for a few weeks.

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.

Worked for about 3-4ish months and then started making loud clanky noise and sharply cuts off with a flashing light and sign. Was working very well and disappointed that it didn't last. It kept my daughter's room cool, who is 1. It sucks for this to crap out right as we're really getting into the most highest temperatures.

This is an incredible invention! I never would have thought it possible to boost the cooling in a problem spot without adding an extra fan for cooling or space heater for the winter. I am using this in my office in my ranch home, but I have recommended it to my children who have 2 story homes and always complain about how hot their bedrooms get in the summer. The booster fan is great looking, and the instructions are very clear and complete. Installation is easy. I replaced an existing vent fan for the booster, and it works and looks like a regular vent as it is flat on the wall. You need to have power nearby to plug it in and that was no problem. The remote control makes operation simple. This is the second product I have received from this seller. I purchased a small ceiling fan that screws into a light socket that is perfect for my loft bedroom. I highly recommend this product and others made by them.

At first, the two I bought worked great. 3 weeks in they started making a horrible noise. I troubleshot and took them out of the duct and cleaned them. One recovered, one is still making a horrible noise. So we took out some screws and checked the fans. Couldn’t find anything wrong, but sounds like bearings are shot. Put back together, wasn’t as noisy, but a few days later, horrible noise again. I’ve worked on these several times to “clean” them. I’m extremely unhappy with the product. Now when they run, they sound like a plane preparing for takeoff. Sometimes they’ll flash the ! And stop working. Complete waste of money, shouldn’t be causing this much trouble after using around a month. I wanted these to be great! 😞 Getting product support is non-existent.
