I currently have some "builder's grade" Broan exhaust fans in my bathroom. Over the last 5 years or so they have gotten REALLY noisy. It looks like it would be a huge pain in the butt to clean them -- the vacuum cleaner nozzle doesn't fit to clean it.
Anyway, Broan sells a kit to swap out the noisy fan (& motor). Are these worth it? And what do I need to look out for in terms of them fitting my existing fan housing? Also, I'm up for any other suggestions regarding quieting these fans. . .
Thanks!

Yes, buy the Broan kit. They are worth the money and for the ease of installation.

Quietness of exhaust fans is measured in "sones". You want the lowest number you can afford. Panasonic sells 1 sone units. The replacement units, since made specifically for your unit will probably work best. You need to figure out the total cubic feet of the room and figure at least 8 to 10 changes of air per hour to know what CFM unit to buy. You can find the formula for this at the link below.

I replaced mine with the replacement exhaust fans in Lowe's or Home Depot. All fans make some noise. My daughter has a six bedroom 8 bathroom mansion and her fans are as noisy as mine. I paid around $13 for mine.
And besides what is the need for silence in the bathroom are you recording your singing while you are in the shower.

Know what you mean. My bath fan also has a heater in it. Sounds like a concrete saw when in use and the plastic on the vents has scorched brown from the heater. I don't know what make exactly, but look for "whisper quiet". I had this demonstrated at a bath shop but like an idiot, I let the remodel contractor put in his own crappy fan. Let us know what you find! I would benefit greatly from this knowledge.
Incidentally, I clean my bathroom vent fans and my car vents with a paint brush (vacuum them first and finish with a clean, dry paint brush).

It depends on where the exhaust flue runs.
if its straight through the wall to exterior of the building then I would install an external unit which sucks the air out rather than blowing it out from the inside.
if your arrangement allows I would install an in-line motor in the loft which sucks the air out of the bathroom and expels it out through ducting in the ridge of the roof or under the eaves

The 'kit ' they sell is a direct fit to the current frame.. A couple of screws & your done. There is a couple of different CFU sizes available.
