Own a old 160 year old home. Now it has reached the time to upgrade the bathroom. Need fan for at least 60sf. This met requirement and was priced nice. Having only a window in the bathroom in the past there was a thick layer of steam on the walls and mirrors. Now with upgrade I actually see the steam rolling across the wall and out the fan. Great product, works great, made in America, and is priced great.
Overall, I would say that this fan is a good bang for the buck. It was easy and quick to install in our non primary bathroom. Best of all, it vents directly out the wall and I did not need to run any duct work. I did not need the extension piece for my installation.ProsSmallEasy to installWorks wellConsA little on the loud side (but not unbearable)
This is a great product, but the flaps are cheesy and I had to cut out and add a screen to keep out bees...
Nice product. I hope it holds up well. My wife and I don't think it's too loud at all. Definitely vents the bathroom quickly!! !
This fan has great airflow and is pretty quiet, I highly recommend this product. Easy to install and super effective in our small bathroom.
If you have ever been frustrated by assembling IKEA furniture, I encourage you to exercise caution before putting a massive hole in the side of your home to install this product.
Works as advertised. Perfect for my need - a third floor living space with a slate roof and brick construction. Had to go through a window! powerful little fan, a bit on the noisy side, but exhausts the bathroom area nicely. Put it on a timer and all is well.
Overall the product is great. However the expandable metal vent pipe that came with it was crushed during shipment. Being that the fit was so tight between the pipe and the fan I had no choice but to throw it in the trash. Needless to say I purchased a rigid piece of vent pipe to use. Fan works great tho.
I installed one of this to cool a closet in my media room where my AV receiver located .This doesn't pull much air and generate more noise then pulling air.Its so lout that you can here it even inside a close closet with TV on with 7.1 surround speakers.In addition it came damage with no sign on packing issues .I would recommend to stir away from this product .
