My apartment checked my HVAC system after my work orders of it not keeping up with the thermostat and weather in this Kansas summer. (Top level, north facing, no trees or shade) After they’d checked the compressor and coolant level they determined the system was “fine”. I did check the airflow temperature which was on spec. However multiple rooms had no air flow. I’m talking I pulled the vents off and stuck my arm into the duct work as far as possible, while I couldn’t feel anything. I also felt no air flow. The heat worked fine during the winter. My teen and tween girls share a room and it’s so hot they use THREE fans. Not only for it being so hot but for noise. I bought one for their room and during the night they shut off their bedroom fans and were bundled up under their blankets by morning. I have since bought three more, one for my son’s room, the bathroom and living space. These are very renter friendly, price is very practical, the only room I’ve noticed the “noise” in is the bathroom as there’s nothing else running. If the water is running you can’t hear the fan. It has fit each vent hole perfect. We love that it has varying speed levels, it’s very quiet, cools almost instantly, we haven’t needed the heat yet. You do need a outlet nearby for the plug in and there’s a remote control with battery included. I did need to drill a small hole for each vent, otherwise you should be able to use the screws from your existing vent cover.

    I was having a problem with my hvac system blowing air into my bedroom and this has helped regulate the temperature in the room much better. It looks good the light is bright as I sleep in a pitch black room but I was able to cover it. Install is a breeze just drop it in size was perfect. You will need to read the instructions for settings but not difficult at all. Can be noisey but I love the white noise and have much louder machines in my room I use when I sleep. Build quality seem good didn't feel cheap.

    The fan definitely helps push more air when the a/c is on. But it really doesn't do much when the a/c is off or when you are using heat. The fan noise isn't bad to me, but i can definitely see where it would bother some people. Cord is extra long, so you shouldn't have a problem reaching an outlet.

    I don't hate it, but i definitely don't love it. I can see using it in a small room that needs a small boost in circulation.

    Product arrived on time and in mint condition. It was package very well with good instructions. Also long enough power cord to reach outlets on average. The power cord has a transformer that plugs into the wall and a 5mm male/female connector right next to the fan, which looks kind of cluttery. But I suppose if you need a longer cord, you can add an 5mm style plug extension cord. The unit comes with two fans hidden under the fan grate and a digital controls to the right of the fans. The controls are pretty intuitive, you control the speed (0-10) and also temperature thermostat control also. The fan works well and brings the temperature in the room down a few degrees to where we want it. The only downside side is the noise, it’s advertised as being 20 something decibels but that’s only on the low setting, so it’s false advertising some. To have the fan effective we have to use fan speeds of 6-10, which is much louder, fan speed 10 is equivalent to a cheap noisy bathroom exhaust fan I guess about 50 decibels or so, it’s noisy. To keep it quiet and effective we ran the fan speed at 6 but it has a slight high pitch whine to it (also fan speed 3-6 has the whine to it). During the day it’s not a big deal but at night in our bedroom it drives us crazy. So we keep our fan at setting 7, which is as noisy as a box fan set on medium but a little higher pitch to it. All in all it does work but it is noisy if you run it at night in your bedroom, during the day when life is active, not much of an issue. I do recommend this fan to my family, friends, and all who read this review, if you don’t mind the noise it produces or you keep it out of your bedroom. Happy shopping!!

    ITS EXACTLY WHAT I EXPECTED. I JUST WANNA SAY FOR PEOPLE WHO ARE THINKING ABOUT BUYING THIS, THIS IS NOT A PORTABLE AIR CONDITIONER, THIS THING DOSNT HAVE ANY KIND OF COOLING THING ON IT, ITS JUST A FAN THATS IT THATS ALL. I RESEARCH THESE BOOSTERS FOR LIKE 3 DAYS BEFORE I BOUGHT MINE, WATCHING REVIEWS ON YOUTUBE AND REVIEWS ON GOOGLE. A HEARD SOME PEOPLE SAY IT DOESNT WORK. THOSE PEOPLE FOR SOME REASON I THINK THEY WERE EXPECTING SOMETHING ELSE. IF YOU WANT THE AIR FROM YOUR REGISTER AND DUCT, TO BLAST OUT, YOU SHOULD GOOGLE A INLINE DUCT FAN, IM NOT A HVAC PERSON SO DO YOUR RESEARCH AND TALK TO HVAC GUY, BUT FROM WHAT I CAN TELL, THE OPTIONS ARE A INLINE DUCT FAN, TO BLAST THE CONDITIONED, COLD AIR INTO YOUR ROOM, OR GET YOUR HVAC SYSTEM FIXED, … BUT THIS REGISTER BOOSTER WORKS GREAT!!. I HAVE A BOUT 9 FEET CEILINGS, I HAVE MINE IN MY REGISTER IN MY CEILING, AND I CAN FEEL THE BREEZE, I LIKE IT BECAUSE IT GETS THE AIR CIRCULATING IN MY ROOM, MAKES IT FEEL LESS STUFFY, AND IM NOT A PROFESSIONAL, BUT I CAN FEEL LIKE THE HIGH HOT AIR PRESSURE IN MY ROOM GO DOWN AND THATS EVEN BEFORE I TURN ON THE AC, ONCE I TURN ON THE AC UNIT, THEN IT GETS NICE AND COOL….🥶🥶.. ITS A COOL NIGHT OUT TONIGHT, AND I HAVE MY WINDOWS CLOSED BUT I CAN FEEL THE COOL AIR COMING FROM THE REGISTER…… I RECOMMEND IT. FOR THE MONEY ITS WORTH IT. ITS EXACTLY WHAT IT SAYS IT IS, A "REGISTER BOOSTER"

    don’t waste your money. The fan is much too small no appreciable difference plus you have to run a cord all the way across the floor to get to an outlet and that looks stupid. We sent it back.

    Moves air well

    Reviewed in Canada on August 28, 2025

    Size: 4'' x 10''Verified Purchase

    At high fan speed it can get a bit noisy but it moves lots of air, lower speeds still move quite a bit and it's fairly quiet. It was installed directly into the floor to help pull hot air up from the basement since we heat the house with a wood stove. Not sure how well it installed in ducting but works great for my use case

    My daughter’s room is the furthest away from the unit, so the AC is always weak in it. This helps push the AC out and creates a noticeably cooled atmosphere in the room. Easy to install, effective and quiet.

    Good air flow booster, can be better.

    Reviewed in Canada on October 6, 2025

    Size: 4'' x 10''Verified Purchase

    My unit was a return – missing screws at minimum; possibly there was a protective film, who knows. That’s the one star down. It still worked so I didn’t bother to return.
    Product is good, works as described. It took me longer than should to figure out how to set it up. Instructions aren’t that great.
    I wish there was a way to control the air flow, like with regular registers. My office has 2 vent outlets: if installed in one of them, ALL air is propelled into the wall, boosting absolutely nothing in the room; when installed into another, air shoots along the wall, which was acceptable. So long story short, know how your duct work is connected to the vent outlets as this fan has no movable flaps on top (whatever they are called).

    Works great on heat; waiting to see what it does when I switch to AC. Easy to install. You can hear the fan but I have yet to see any fan be inaudible. Goes with the territory of using a fan. Noise is very low – I have it on setting of 8 out of 10.

    Effective device, but bright lights

    Reviewed in Canada on October 23, 2025

    The device does work well, it pulls a good amount of air through the vent and into the room. It works well with hot and cold air.

    I did find the lights quite bright for a nursery, and not having a remote to control makes it inconvenient.
