We step in the shower day in, day out with the desire to wash our cares away and then step out feeling clean and new.
Without a shower exhaust fan, we may not keep a stress-free bath routine.
What it does is vent air to the outside, perhaps the garage or back porch, swiftly to remove moisture, which creates steam and odors plus invites mildew and mold.
A shower exhaust fan prevents the mold and mildew buildup due to moisture much like a computer exhaust fan prevents the heat buildup due to dust.
The typical variety is for ceiling, inline, in-wall and exterior wall mounting.
Choose from a single grille, dual grille, 2-speed, passive inlet vents, one-vent and ductless exhaust fans, as well as combination fan/heat types, with or without a warm light and/or night light.
Single grille fans will have a ceiling-mounted small-scale grille plus a remotely mounted fan motor to spare space in the bathroom.
They fit a smaller sized shower bath, vanity or powder room.
Double grille fans will have a remotely mounted fan motor for spot ventilation at the source, moving air in multiple areas all at once.
They suit the larger sized spa-like luxury shower bath that's popular these days.
A good shower exhaust fan is made with components of rust proof stainless steel that can function at lower temperatures to prevent overheating, for durability.
