    Rated 3 out of 5 by from Poor Sensor Replacement I've had this model for 2 years when the humidity sensor attached to the grille starts malfunctioning, fan runs continuously. Can't find anywhere to buy just the sensor, Pretty poor design if the most important part that controls the fan is not available. Broan sells a grille assembly with spring clips and sensor wire for $73 but it does not describe a sensor module included. Probably is included but not going to pay $73 to replace a sensor!!

    Rated 5 out of 5 by from Quiet and Fast. Eagerly awaiting replacement of other noisy fans. Whisper quiet, clears smells and humidity impressively quickly. Installation is only easy if construction is perfect but if replacing another model, it will be a bit more difficult. Technical support is excellent. **Note that this is item has automatic humidity sensors and on and off for de-stinking. You may opt for manual controlling as we did.

    Rated 5 out of 5 by from Problem Solved With no A/C return for this bathroom "in a pocket" we installed this exhaust fan with humidistat and run it 24/7. No more mold and mildew!! We needed the most powerful exhaust we could get with a 4 inch duct, a humidistat and installation from "below" (versus attic). This item met all the requirements and seems to have solved the moisture problem. There is even a dial for manual control of the humidity. The footprint is bigger than the old exhaust fan so we had to enlarge the opening in the ceiling. For a DYI installer more detailed directions would have been helpful because we had to figure out how to to remove the motor from the sleeve to access the existing duct and hook it up to the new one.

    Rated 4 out of 5 by from Excellent fan, but a bit sensitive to ambient humidity I purchased this for it's noise level and humidity sensor because I did not have the wiring to add an independent timer. Generally this unit works very well and it is nice not having to remember to flip a switch as it automatically turns on when the humidity increases from the shower. However, on really humid days, the ambient humidity in the attic/exhaust vent duct is enough to trip the humidity sensor and turn on the fan. This becomes problematic in the summer when the unit keeps turning on and evacuating air conditioned air.

    Rated 4 out of 5 by from Good Value The unit was easy to install at a decent price. The settings are a nice feature that you can customize when it comes on & how long it runs for. It's more than just a blower you turn on & off. A lot quieter than the unit it replaced.

    Rated 5 out of 5 by from I love my new bathroom fan. Works fine, love the moisture sensing feature, looks good.

    Rated 5 out of 5 by from Excellent performance, features Humidity sensing and turn off timer are excellent features, both adjustable, work as advertised, and provide exceptional ease of use. The unit is so quiet it is very helpful it turns itself off. The one thing I would consider doing differently is sizing it better for my bathroom. I bought the 110CFM for my 65 square feet which is a little over kill. I probably should have used a smaller fan and could have used a 4" duct rather than 6". I will definitely buy another Broan sensing for my next bathroom remodel.

  • Do I need to use a switch?

    Can I leave this unit permanently powered above a shower? I would like to run power piggybacked from a GFCI receptacle and leave the unit permanently powered as this will be a second fan in the bathroom whose sole purpose is to remove humidity due to shower use (my wife takes hot showers and often forgets to turn on the bathroom fan which is leading to a mold problem)
    Asked by: Rick
    Yes, that is a perfect application. The humidity sensor will turn itself on / off based on the humidity you preset it to, with the power to the unit on all the time. The unit works very well and is as quiet as advertised.

    Can any of your quiet fans (humidity sensing or switch operated) have 2 units share one duct (for back to back bathrooms?

    Asked by: Walt
    With appropriate sized ducting, in case both fans are on at the same time, it should work fine. Each fan has louvers at the junction to the duct (the black part in the picture), so will prevent back flow into the second fan.

    Do you have an option for remote humitity sensing that can operate this fan or others in your line?

    Asked by: Rob
    We have a dehumidistat control that can be used with our exhaust fans and the model is DH100W. This control mounts into a single gang box on the wall. It has variable settings from 20-80%. You may purchase this Item from one of our dealers and they can be found at the "dealer search" on our website.

    What is the factory humidity setting for automatic turn on/off?

    I'm considering purchasing this fan and want to know more about when it comes alive on its own.
    Asked by: Peter
    Thank you for your question on the QTRE100S humidity sensing fan. The humidity control sensitivity should not require any adjustment, but it can be if needed. On the side of the humidity control there is an adjustment potentiometer which is factory set a 100%. If the fan is responding to outside conditions or not soon enough, the sensitivity can be increased or decreased. Please contact our technical support for further assistance at 1-800-637-1453.
