    Rated 5 out of 5 by from Look the quietness We love how quiet the fan is when it on, and the lighting is just right. We did have a little trouble understanding the wiring but we are not electricians, so we opted to have one install it. It took him about 30 minutes and he was done. Love the product and will recommend it to others.

    Rated 5 out of 5 by from Great for removing moisture!! Excellent product all the way around!!! Fairly easy to install although I gave it a 4 due to the fact that I had to vent it through a soffit. Excellent at removing the moisture. I would recommend this for any bathroom large or small because it is extremely quiet as well.

    Rated 5 out of 5 by from Love the bathroom fan We purchased the Broan fan for use in a new construction of a 2nd bathroom. We love it, especially the night light that is motion activated. At first, we had a problem with the light flashing constantly, but very short flashes. We discovered that our lighted wall switch was the problem. We changed it out for a regular switch and everything was fine.

    Rated 4 out of 5 by from This fan has great features The fan with light and night light give off a lot of lite. The night light is great feature during the night and the fan is quieter then the original home builder supplied fan.

    Does this unit need to be vented to the outside? If only to the attic will it accumulate moisture and mold?
    Asked by: Sue
    I believe they recommend that all bathroom vent fans vent to the outside. If venting into the attic the moisture will/can accumulate on the decking causeing mold growth. I installed mine with an eve vent and it was pretty simple.

    I prefer to use a regular incandescent light bulb. max watts?

    We have our fan and light separated to different outlets so that we can dim the lights on a dimmer, and then wired the fan portion to a spring wound timer. I want to use incandescent bulbs for this. 1) CAN I? and 2) what is the maximum wattage for the bulb?
    Asked by: Betsy K
    Betsy, I have same issue and will probably use a lower wattage with warmer color GU24 bulb (2700K ~ incandescent) as I have a larger light already in the bathroom. I might even just just one bulb. I plan on using the vent light for winding down at night or to contrast the bright 4100K light I already have. There are GU24 to Edison Base adapters but then you'd have to find a specialty bulb short enough...not worth the trouble. Although they recommend incandescent C7, I use LED C7 for other bathroom night lights and they don't get hot and will last a lot longer! Note, all CFLs have poor reliability and take time to brighten.

    I need to replace the light bulb in this model. How do I access the bulb? I don't want to force or break the fixture.

    Asked by: Zip
    Look in the installation booklet. It shows you should use a small flat blade screwdriver on either side, long side, of the lens and gently pry it off one side. The other side will pop out. The bulbs are special so be sure you get the correct bulbs for it.

    How does the night light work?

    Asked by: Elwrong
    You will need to have a separate switch with wiring in order to use the nightlight. You will also need separate switches for light and fan if you want them to run independently.

    Loud exhaust fan

    Put in this new fan to replace old loud one and this one is louder Any suggestions why
    Asked by: Cj
    If you used the 6" exhaust duct, it should operate at 1.5 Sones. If you used the reducer from 6" to 4" the Sones level will be higher and the CFM slightly lower. Unless there is a problem with the fan turning freely, it should be fairly quiet. It also depends on the specs of the fan you replaced.
