I'm looking to get a new exhaust fan for a 65sq.ft bathroom. I'm
considering a specific fan but it comes with 2 exhaust ducts, 4"or6".
Is there a real difference? Doesn't the motor still draw the same
Also, with soooo many 'clearing houses' on the Internet these days,
does anyone have experience with a good reputable site. The prices I'm
seeing can be $35 cheaper than Home Depot, Lowe's etc. Thanks.
When you want to return it, will the $35 balance what a pain in the ass it
is to package it up and go to the post office? Also, I've gotten stuff like
that cheaper at local electric supply stores than at the big chains or
online. It's not supposed to be that way, according to myth, but it is. Same
with faucets I've bought at real plumbing supply and bath showrooms.
Many manufacturers are going from 4" to 6" ducts to keep the units quiet. I
would get a 6" unit, and if you want to use 4" duct, just go to depot and
get a 6 to 4 reducer. The unit will have slightly lower CFM's and produce
slightly more sones. I've bought Broan and Panasonic units from WAM and Wave
Plumbing online sights and will do so in the future without hesitation. The
last unit I got was from Wave Plumbing and saved over $100 over local
The fans that are 6" usually can also be adapted to 4" and the
manufacturer's website should have specs that show how much air it
will move in either case. Then you can decide based on air flow as
well as any installation issues you have with 6 vs 4. I'm also with
Ed on making sound level a top priority. Given all the work
involved, I'd rather spend $75 more and get a nice quiet one instead
of saving a few bucks.
Thanks for the replies.... I was considering the Broan, or NuTone,
but looked at the Panasonic as suggested.I found a Panasonic Whisper
Quiet, rated at 0.8 sones,online. Pretty quiet compared to the rest.
It's a 110cfm, paid $108 free shipping. If anyone cares I'll give a
report when it arrives and I install it.
Broan and Nutone are the same company. In my opinion, they only make one
model fan that's decent, which is called "ultra silent", and the truth is,
even though it is very quiet and has a really nice blower unit in it, it's
still built into a pos tin foil box, that has no integrity, and unless it's
blocked and screwed to death, will cause vibration noises. You will be very
pleased with the Panasonic, trust me
