  • 671R is rated 3.9 out of 5 by 9.
    Rated 4 out of 5 by from Does everything a fan should do. We moved into a house that had no fan in the restroom. The steam on the mirrors was irritating. After the fan was installed I told my friend "the good news is there is no fog on the mirror when I get out of the shower, and the bad news is since there is no fog on the mirror I can see how fat I am-haha.

    Rated 1 out of 5 by from Noisy in the extreme My old exhaust fan vented into the attic, so when I had the roof replaced, I also had a new exhaust fan installed that could vent outside. However, the fan does not seem to vent very well. (After I shower, all mirrors and windows are completely steamed up.) Of more significance, however, is the noise level of the fan. According to the fan's specs, the noise level should be about 3.0 sones, about the noise level of a babbling brook. The noise level of my fan is about that of a garbage disposal. Needless to say, between the inefficiency of the fan and the noise level, I am extremely disappointed.

    Rated 5 out of 5 by from This bathroom exhaust fan will keep the mirror from steaming up. I was looking to upgrade my bathroom exhaust fan to one that was stronger than the minimum requirements. This NuTone 671R exhaust fan was powerful, yet I got it at a good price. I wanted a fan that was strong enough to get rid of any condensation from showers that can lead to mildew & mold and one that would keep the mirror in the bathroom from steaming up. To me the one sign that the fan is doing the job is how well it does in clearing the steam that fogs up the mirror. Well so far with this fan, the mirror doesn't even steam up at all.

    Rated 5 out of 5 by from Excellent fan! Replace very LOUD fans in 2 of my bathrooms. These are so quiet and powerful! Will be changing out a 3rd bathroom soon for one of these!

    Rated 3 out of 5 by from Two bathroom fans - 1 is great the other not so great! I have 2 bathroom vent fans installed and the one fan is great - very quite, has a timer switch installed that can be programmed for on/off operation and this one is great. The other fan however is very noisy and sounds like a motor boat at times. I had the installer check it but everything appears to be installed properly but I am still not satisfied with the operation of this particular vent fan.

    Rated 3 out of 5 by from good price - but too loud this fan is a good price; and high quality - but is advertised as a low sone (quiet) fan -- it is as loud as the fans in our other bathrooms.

    Is there a new generation motor with a capacitor for the 671?

    Asked by: Grant
    Thank you for your question on the model 671 exhaust fan. The motor for the 671 is an original replacement part and does not have a capacitor. The 671 is an older, obsolete model and the 671R is a current model. These are different versions and revisions of the same fan and the parts are not interchangeable with each other. Please contact the Technical Service Department at 888-336-6151 for further assistance.

    Will internals fit model 663L / 669L rough-in box?

    Have model 663L / 669L fan with light. Want to convert to fan only. This model appears to be almost exact fit dimension-wise. I suppose i could remove light on older model and purchase 671R grille to work at minimum. I was hoping to upgrade fan motor too. So, do innards of model 671R fit into model 663L / 669L? Don't want to replace entire unit if possible.
    Asked by: FanGuy
    Thank you for your question on the models 663L and 669L exhaust fan/lights. The insides of the 671R will not work in the 663L or 669L housing. The motors for the 663L and 669L are no longer available and there are no substitutions for them. You will need to completely remove the current unit from the ceiling and install a new model.
