Inline hydroponics duct fan to improve bathroom?

I need better bathroom ventilation. The big box products are just weak and under-engineered.

What about a hydroponics duct fan? Any opinions?

Or what have you done, to upgrade bathroom ventilation?


Fan location up in ceiling in attic, 4 inch duct runs to soffit eaves.
Objective is to move more air to reduce humidity accumulation during and after showers, etc.

To keep it simple take out what you have and just put in a bigger CFM motor.A lot of models will use the same mounting box if you use the same brand name.

I put these in both bathrooms a couple years ago. Similar to your idea, I think. 6 or 8 inch duct. Fan's on the roof.
Works great, almost silent. I installed timers so they wouldn't run all the time. If you wanna go conventional, Panasonic makes a nice fan.
