4 Inch Wall-Mounted Exhaust Fan, Small Bathroom Fan, IPX4 55CFM Window Extractor Fan w/with Anti-backflow Check for Toilet, Office, Kitchen

I installed this fan/light extractor in my outdoor kitchen cabinets about a month ago to help with air circulation, and it’s been working great. It runs very quietly — barely noticeable — but moves air efficiently and keeps the space well ventilated. I also purchased a 4-inch air duct and an exterior vent cover separately, and everything came together smoothly. Installation took me about 30 minutes. For a compact and quiet solution, this fan is definitely worth it. Highly recommended for enclosed or semi-outdoor spaces.

Item is quiet and works well. Indicator light is helpful

I got this for my RV for the front window during the summer. Works well enough to pull some heat out of the front of the trailer. It was easy to install because I placed it in a small window. I use some other items to cover up the rest of the window and it seems to be working well. I wish it was a little stronger. It is very quiet. Decent price for what it is. You can really use these fans for anything.

Works great in my chicken coup but the spring broke that keeps the Louvers closed.

very nice and quiet. CFM is way over rated but..it does suck enough air to vacate your pooop smell

I have an old, little house that is currently unoccupied and that will be unoccupied for at least two more years. I need the house and its contents to not mildew. I bought a dehumidifier to control the moisture in that old house, but I needed a way to circulate the air. I bought a set of these. I then cut little (repairable) holes through specific walls, and then installed these fans in a way that made the air circle inside of the house. They are nice and quiet and move enough air to really help. The power cord is nice and long, but it if a person wanted to, he/she could use the screws inside the fan's case to change the cord.

Very powerful little fan. We didn’t plug it in, both rather spliced it into our electrical system. Works great.

The air flow this product produces is very low.
