Our master bath doesn’t have an exhaust fan and I’d like to add one to help with the humidity. It’s the primary bathroom of use upstairs and the 2nd full bath is on the other side of the wall.
Can I use a splitter to tie the other bathroom’s exterior vent to the new exhaust? If I did I’d put the splitter closest to the vent to help prevent blow back to the other bathroom. They’re both smaller bathrooms (50sqft and 100sqft).
Or is it just better to put it on it’s own exhaust vent?
I have one that I can adjust the CFM and the time it takes to shut off. I have it configured to run for 5 minutes after I turn off the switch on the wall. This does require you to run power directly to the unit and a signal wire to your switch. I believe they also make electrical switches with timers that are easier to retrofit.
