Panasonic’s venerable WhisperLite ventilation fan has undergone a makeover. The new model is covered by an unobtrusive flush-mount grille and takes a single 32-watt CFL bulb. The blower design has been tweaked to ensure that the fan’s ultra-quiet performance doesn’t suffer if the ductwork is lengthy or complicated. The 110-cfm unit (FV-11VQL5) costs about $175.
