HG Power 6 Inch Exhaust Fan with Speed Controller, 308CFM Wall Exhaust Fanfor Kitchen, Bathroom, Metal Extractor Fan for Pet Room, Smoking Room, Attic, Garage, Window Ventilation

The fan had very good air flow. It was quiet in the low fan speed setting and just more louder in the highest speed. It has a solid build.

I’m in a place now where 1st through the 3rd floor all have the same exhaust vent in the bathroom. Recently it stopped pulling air out. Maintenance is compeltly incompetent so I went ahead on my own and installed this to pull the stale air out of my place while also protecting the bathroom from mildew. Maintenance doesn’t even seem to care about the fact that long term this is very damaging and bad for one’s health. Anyways this device is perfect. I can’t seem to understand why there are any negative reviews on it at all. It’s perfect. Also, this can’t be found in store anywhere. Amazon is simply the best. Thank you for saving me from breathing humid and mildew air and co2 air from having no other place to escape. I’ve been struggling for a week now with sleeping due to the Dallas heat and humidity with this building being run down. Installed a window ac unit and now have this fan going. At least now I know the air in here is much cleaner with stale and humid air having somewhere to escape finally. Life saver. Thank you

As others have noted this is a heavy duty quality built 6" fan. It moves a lot of air (300 cfm not sure, that's a lot of air. I have equipment to measure the flow just haven’t done it. One of these days...) The noise level comes from the air, not the motor. You can't move that much air through a small fan quietly. Its very quiet at minimum speed which still moves quite a bit of air. Guessing slightly less than half speed. Some fans on a speed control whine at reduced speed, no trace of that here. I dropped it a notch because the speed controller is mounted near the plug instead of near the fan, inconvenient. It also operates backwards, starting at maximum instead of minimum speed as others I have do (have several AC Infinity fans also high quality). Not logical either and usually want minimum speed so have to turn quite a bit. Minor but... On value for the price I give it a 5. It's worth the money, but advise buying the one with the speed control unless you need the full airflow all the time, and noise is not an issue.

At first I was sceptical, but after it came, I was stunned, works perfectly,couldn't have bought a better one...

Very poor quality. 2 bought and installed. After a few weeks both had speed control problems. Low speed now longer goes low. This developed over time. One had noise develop after about 2 weeks.

It is still working for now, but after about a month of use it has a clicking sound like something is about to go out.

I got this to get some ventilation in the chicken coop. It's ~15square foot. The 6inch exhaust fan does a nice job. It pushes hot air out easily. No problem with the install. We put it on the wall up close to the roof where the hot air lingers. The hardest part was cutting out the circle in the wall. Very much worth the cost. I was worried it would be loud. On low is very quite. On high to my surprise wasnt as loud as I thought it would be. The chickens love the upgrade as well.

Easy to install. Runs quietly. I use this to push air from our restaurant's dining room into the kitchen area. This helps keep fumes in the kitchen, as well as providing a bit of cool air flow to our insanely warm commercial kitchen. The doors open and close as expected. Variable speed works fine, though we always run it at max speed. All black color has a clean look and should work well in a commercial setting.

Muy buen equipo, excelente calidad

I've used it seriously for the past 2 weeks. So far it is excellent. Great power at full speed. The noise the fan makes isn't harsh on the ears (which isn't something all fans can say). I would definitely buy it again should I need a unit like this somewhere else in the house.

Installed (2) 6" fans in the back wall of my shop. We're easy to install and look clean from the inside. The open back with back draft is not a proper exterior fnish tho. Definitely needs some sort of vent or finish cap. Wish I included this, but I guess it's not necessarily part of the exhaust fan... Now to the important stuff. I honestly expected more power. They are kinda low and slow and don't overly move a crazy amount of air. My rooftop vent fan in my rv seems to pull more.. not really a fair comparison tho, 250 dollar fan and these are 1/5 the price. So you get what you pay for. They work, look nice, but arnt "excellent"

Fonctionne parfaitement et belle allure autant pour la salle de bain que la cuisine. Je la conseille fortement à qui en a besoin pour le chalet car ça ne prend pas beaucoup d’espace. Elle a plusieurs degrés de vitesse et c’est un bon point car on peut la laisser fonctionner longtemps sans être dérangé par un bruit de fond agaçant.

good a tad loud, but variable speed makes it good
