Second the unit's fan is designed to deliver air quietly with only a gentle whoosh.  That's why Mr. Slim is the first choice for thousands of homeowners with problem bedrooms, basements, kitchens, bonus rooms, as well as older homes without ductwork, hot or cold spots and replacing ugle window units.

With Mr. Slim systems you can sleep in quitet comfort and with a sense of security.
