Question: Can the humidity ON setting be adjusted?
Document: we end up leaving it on because we can't tell it is on.works great. would definitely purchase another one.
it looks really smooth and runs really quiet.this is my first bath fan. i def recommend this bath fan
i needed a small quiet fan for a good price and this fit the bill. tired of broan/nutone fans. i recommend this one.
Worth the money. Pretty quiet in comparison. I would comfortably recommend this fan to anyone. A little difficult in installing.
We installed this Delta BreezeSlin 50CM fan in our small powder room. It has a 3-inch vent for those who have the same size duct. Their claim on 1 Sone is pretty accurate, we have a .3 Sone Panasonic in the master bath and it is comparably much more quiet.The fan is a breeze to install, pun intended. :)  We needed the 3-inch vent after checking our ducting for the powder room, while our master bath has a 4-inch duct.
We got tired of our $13, 4+ sone screaming fan in the guest bath and decided to replace it with this 50cfm Delta slim model. The week before I replaced the other bath fan with a Nutone QTN80E from a local home supply store. That was fine but I had to add some framing to support it because it is designed for 2 x 6 ceiling joists and we have 2 x 4 trusses. This Delta slim model promised to solve that problem and it did.
We got this to replace an old 25 year old small bathroom fan. The challenge was to find such small size so that drywall didn't need to be cut. At first I went to Home Depot and bought a small replacement fan. The only one they had in this size was 4 sones. And boy, it was even louder then the 25 year old one. It drove everyone crazy, so I went to Lowes, but couldn't find anything in such small size.
We changed out our fan that was 2.5 Sone with this one and it makes a world of difference. It is so much quieter than before. It even has a green light on the fan that will light up when you turn on the fan. The fan is smaller than other kinds so make sure you measure the hole before installing.
We bought this to replace an old fan in our bathroom that was so noisy. This is soooo quiet you forget it's on but it has a green indicator light to let you know that it is running. Great buy and great product!
We are so happy with the two ceiling exhaust fans that we ordered to replace old broken ones in the two public bathrooms in our new building. They are Quiet!! Good value. Thanks!
