Rated 2 out of 5 by Daver Disappointed.... still loud
We still use the original 15 year old 696 B Unit fan and has always been loud. I finally bought the 690NT Upgrade because it is easy to install and is supposed to be 3 sone instead of 4 sone. I don't believe I can tell any difference in the sound level and will be looking for a better one. NO WAY IS THIS 50% QUIETER as the box says.
Also, I had to go back to Home Depot to return the first unit because the holes were drilled incorrectly in the large mounting plate. The replacement was drilled properly and installed easily to the motor. The plastic deflector strip could not be installed either as the directions show.... No tabs in my square box at all. So, I drilled holes in the box for screwing thru the two slotted holes in the plastic strip and mounted them. It still made no difference in sound level either way.
I would have been better off buying a completely new style 'quiet' fan.

Rated 5 out of 5 by Tinker This product is a breeze to assemble and install.
Product replaced my model 688 Broan installed 23 years prior. Product is quieter than the old and the price is fair

Rated 5 out of 5 by Keystonekid64 Excellent Upgrade
I purchased this fan upgrade because my bathroom fan became extremely noisey over time. This product was a direct replacement for my current fan and was easily installed with common hand tools. Installation instructions were straight forward and easy to follow. It has been quite some time since the upgrade and I have not had any issues with this product despite the heavy usage(2-3 Hrs per Day).

Rated 5 out of 5 by FrankenDezul What a wonderful upgrade
I purchased the 690NT Fan Upgrade kit to replace ours that started making noise and the instructions and install was very easy. Definitely a do it yourself kit. Fan now is much quieter than the original ever was. So far product is satisfactory and plan on replacing the other fan just for the lower noise level.

Rated 5 out of 5 by Bob63 This product relly lived up to expectations!
This upgrade unit advertised more flow and quitter operation with easy installation. It only took about 20 minutes to install including cleaning of the mounting box. My box did not have the tabs to clip in the plastic flow barrier but it fit in and stayed in without the tabs. I used a 4" flexible discharge to the roof vent. This bathroom fan went from very noisy to quitter than my much more expensive new fan I installed at the same time in my other bathroom.

Rated 5 out of 5 by Debbie A great upgrade for venting in our Bathroom
Compared to our former vent - this is so much better. We barely get steam on the mirror anymore and it is quiet sounding. We are not handy people when it comes to installations - but, we did install it our selves and it is working great. We only had one problem in the installation: the vent movable valve was hard to keep in place so we just removed it. We have not noticed any cold air coming down the vent and we thought that might happen since we live in Minnesota.
