  • Rated 3.8 out of 5 by 13 reviewers.
    Rated 4 out of 5 by Inexpensive and easy to replace busted vent fan Was very easy to remove old one and put in new one. Literally plug and play. Interesting buying the whole unit was cheaper than just buying the replacement motor which I would have preferred since I did not need to replace the box and grille. September 4, 2014
    Rated 5 out of 5 by Needed to replace existing fan and this model fit perfectly, is more quiet and was reasonably priced. What more do you need? Easy to install, quiet and a great price. Good product. March 26, 2014
    Rated 5 out of 5 by it is a good product a reliable and powerful fan at a reasonable price. Will buy the same product in future. March 10, 2014
    Rated 5 out of 5 by great price, clever design Great fan, maybe, if there is a deluxe model, it could be quieter, but its not too loud March 10, 2014
    Rated 4 out of 5 by existing fan replacement We installed this replacement fan in 3/4 bath. The fan is strong and clears shower dampness very efficiently. But it is loud. If the instructions for replacing the fan with a plug were clearer, I would have been able to replace the fan myself rather than hiring someone. Since the existing fan plugged into the ceiling, it was very easy to replace; no wiring or going into crawl space was required. The instructions didn't say how to remove the existing fan (same type). Since we were replacing an existing fan of the same type, I wish I could have purchased this model without the housing; I just had to throw out the brand new housing; a waste of money and materials. Overall I would recommend this fan for a replacement; this one fit into our existing fixture perfectly. If you are installing a new one without an existing opening, then I would suggest you look for a model which is quieter. Our old one lasted 22 years; I assume this model will be as reliable.

    Rated 4 out of 5 by Over 6 months now and works great 6+ months ago i replaced my small bath's fan. i can not complain AT ALL..... for the price it sells this is absolutely amazing!! It removes foul air efficiently and works like a charm. With respect to noise level.... it is noisy, but i do not visit the toilet for reading or napping and have no problem with a little noise side-effect for 2-3 mins. I was very skeptical buying it because i thought it would not last for the ridiculous price i paid. So far so good... August 21, 2013
    Rated 4 out of 5 by Loud but work well in smaller bath. Have this in both baths. Works great in 40 sq. ft. bath. Noisy is my complaint since it is next to my TV room & have to turn tv up when it is on. Builders also put same model Broan 688 k in my larger bath, 80- to 85 sq ft. I understand why it seems much quieter now. 50 cfm not enough power. No suction. July 30, 2013
    Rated 3 out of 5 by Motor bearings fail. The bearings fail and the motor seizes up after a few years. I have several installed in my apartment building and I have to replace a motor unit every couple years. Higher quality bearings/lubricant should be used. Mike June 11, 2013

    I want to upgrade to the quietest fan that will fit the existing box. Is there one that I could add a light to.

    Is there a grille that is a little bigger that will fit the 688? Had it installed but the grille didn't quite cover up the entire opening in the ceiling.

    Thank you for your question on the model 688 exhaust fan. The only parts available for the 688 would be the original replacement parts. You will need to patch the opening in the ceiling.

    Thank you for your question o nthe Broan model 663-B. This model had a housing size of 8" x 8 1/4" and used a 3" duct size. The current 688 has a housing size of 7 1/4" x 7 1/2" and still uses the same 3" duct size. The 684 offers a housing size of 8" x 8 1/4", but uses a 4" duct size.

    Wanted to confirm that model 670 will replace the 663-E/688-E.

    3" duct. Ceiling mount.

    May be a 25 year old fan. Worn out and pretty noisy. Would like to unplug and replace. I presume that's easier than trying to get a new motor/parts for this older model?

    Thank you.

    Answer: 
    Thank you for your question on the Broan model 688. The 688-E model has a housing size of 8" x 8 1/4". The current 670 model we offer has a housing size of 7 1/4" x 7 1/2". The hole opening in the ceiling would not be the same size and parts would not be interchangeble. We do have replacement parts available for your 688-E model. Please contact customer service at 800-558-1711 for assistance.
