A couple things... Normally in most bathroom remodels I install a 110 cfm Panasonic fl combo. 2 customers have made comments about it not clearing shower steam well enough. Yes I did the cfm math. Any reccomendations on a higher air moving fan light combo? Also are there any better heat fan light combos than the whisper warm Panasonic?

What's the ducting like? Makes a BIG difference.
I've installed dozens, if not hundreds of Panasonics and never one complaint, and only one motor failure.

The two complaints I had were roof ducted. You think that has an effect vs horizontal? Or are you referring to distance/bends in ducting.
No they've been remodels but new 4" duct on both jobs I've gotten comments on.

I've never had fans clear steam from a hot shower.
Here is the Panasonic installation instructions. Pay special attention to the "Cautions" section:

You need to make sure you are not creating a negative air environment and that you are not bending the heck out of the duct work. The same concept of pulling wire through conduit applies to ducting.....The easier the bends, the better the air will flow through them. Resistance is gonna kill you by creating noise and lack of airflow.

I think this is the case. I also think you have a couple of hyper-picky customers.
One of the customers was a friend of mine who installed a beautiful double shower. When both are running hot water it creates twice the steam. Maybe I shouldve installed a different fan. Which I still haven't heard any reccomendations! ! Come on.... you're telling me BBQ doesn't have experience in this regard? !

F/L combos only go up to certain cfms
If you look at their specs, they will usually dictate the sq footage they are good for
for instance, i've installed a 300cfm fan only until in my bath w/6" duct
it clears shower steam....

This one is a tad noiser than the Panasonic fan and you may need additional heat but I will gaurantee it removes the steam and you'll never get another customer complaint.
Install it properly and it will even remove the customer.:thumbsup:

Fan lights with heat tend to have a lower cfm than just fans. Also if the customer leaves the door open to the bath area it will not remove the steam as it would with the door closed. Also a 100 CFM fan will take 4 minutes to change over the air in a bath that is 8x6x8-- that is a relatively small bath
That will send the fart over to the next county.:laughing::laughing:

The problem with some bathrooms is there is no make up air. Like my downstairs bath. When the door is closed it creates a tight seal and the fan is trying to pull air out but no where to pull it from so instead of 115 cfm you might be getting only 75 or less. If I crack open either the door or window it will work much better...my bathroom upstairs has a decent gap under the door and its probably enough to allow air flow...
Also small baths tend to get overwhelmed by steam much quicker..so you need to go bigger with the fan.
I have become a big fan of remote mount fans...

If you have a forced air system, make sure there's a fresh air intake installed. It won't take care of all the problem unless you've foolishly installed a return air duct in your bathroom!!!
Exactly. This is the problem with MANY bathrooms. Have a contractor install fresh air or simply shave the door a bit and I bet you will see a huge increase in exhaust CFM.
