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

love it worked great

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

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.

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.

It's been running continuously for several weeks without issue. Seems well built. Time will tell how durable it is.

For the money the fan does what it says it does. The plug and cord would be better with an option to come through the front cover. I bought this for a outside wall. When you push it into a 4 inch opening the plug is inside the wall. Other than that it does ok for Little Odors. I wish I'd bought a more powerful one.

Awesome for the price. Quality seems good and has back flow valve.

I recently installed the 4-inch Black Bathroom Exhaust Fan in my half-bath, which tends to get a bit stuffy, and I'm quite impressed with its performance for its size and price point. Compact Design, Sleek Look: The 4-inch size is perfect for smaller windows or areas where a larger fan just won't fit. The black ABS housing gives it a modern, discreet look that blends well with most decors. It doesn't scream "utility fan" which is a plus. Good Air Movement for its Size (55 CFM): With 55 CFM, this fan is definitely designed for smaller rooms like a half-bathroom, a compact laundry closet, or perhaps a small office or kitchen where you need to clear localized odors. It effectively pulls out humidity and mild odors from my half-bath, preventing that lingering dampness after a shower. For a larger bathroom or heavy cooking fumes, you might need something with higher CFM, but for its intended use, it does a good job. Quiet Operation (for an exhaust fan): One of my main concerns was noise, and I'm pleasantly surprised. It's not silent, but the hum is fairly low and unobtrusive. It's much quieter than some older, larger exhaust fans I've encountered, which is a big win for a bathroom or office setting. IPX4 Water Resistance & US Cord: The IPX4 rating is reassuring, making it suitable for damp environments like bathrooms. The plug-in design with a US cord made installation incredibly simple for my window mounting – no complex wiring needed if you have an accessible outlet nearby. Just plug and play! Anti-Backflow Damper is a Smart Feature: The integrated anti-backflow damper is a crucial addition. It prevents cold air, insects, or odors from coming back into the room when the fan isn't running, which is a common issue with simpler exhaust fans. This shows good design thought. Installation (Window/Attic/Garage): While I installed it in a window, its design also lends itself well to attic or garage ventilation, especially for spot extraction. It's lightweight and relatively easy to mount. Overall Impression: If you're looking for a compact, effective, and relatively quiet exhaust fan for a small bathroom, toilet, utility closet, or a specific spot in a kitchen or garage, this 4-inch black exhaust fan is an excellent choice. Its plug-in convenience, anti-backflow damper, and sleek design make it a great value. Just be mindful of the 55 CFM for the size of your space.

This little exhause fan was perfect for my application. Easy to install and simple to plug in and mae it work. Ity has been running for over a year. I would buy it again

Extractor en baño para evitar acumulación de humedad. Muy eficiente y muy silencioso

Après quelques jours d'utilisation le clapet de sortie d'air ne ferme plus complètement, les ressorts sont minuscule et faible, dommage le reste est plutôt bien.

Quiet, discrete and efficient, love this little fan I have it running on a timer at intervals and the air in the cold room is no longer smelling musty and dingy, smells fresh now

Love this product to help move air in small apartment - have it by air return and feel fresh air is better circulating. LOVE THIS PRODUCT
