I live in a 1978-built condo which leaks air and I can’t stop smoking. A bathroom fan of a high-volume but QUIET (I love my music) in my 812 ft^^2 condo…don’t want to send smoke odors to neighbors. Tried a nu-tone and have a vent to the outside, drywalled over the old fan but preserved wiring and vent tube (flexible dryer-duct run of about ten feet.
Many years ago there was a project with a whisper-quiet (how many sones?) fan for a bath. can’t find on internet. Running it continuously is my plan but can put in switch too…may want an array of fans–smoke gets in wood-frame leaks and annoys people. Please help me locate the part and/or tell me how to pressure-test the dryer vent for leakage.
