A bathroom that clears fog off the mirror and pulls damp air out before it settles into the drywall needs a bath fan sized to the room, and the Milano TY-110-E bathroom exhaust fan moves 110 CFM at a quiet 1.0 sone — enough to ventilate a full bathroom up to 105 square feet without the drone that makes people leave the fan off. The galvanized steel housing resists the corrosion that kills lesser fans in a high-humidity room, and the whole unit installs from inside the bathroom with no attic access required, which turns a dreaded retrofit into an afternoon job. ENERGY STAR qualified and HVI-certified for rated airflow, it draws little power for the moisture protection it delivers — the quiet, unglamorous piece of a bathroom build that keeps mould out of the corners and paint on the ceiling for years after the renovation photos are taken.
