Dryer Fan. With the Dryer Duct Booster you can set up a laundry room almost anywhere in the house without worrying about the length of the exhaust run or the number of bends. It can be installed horizontally or vertically and maintains proper exhaust velocity in duct runs as long as 100 feet. Unlike competing fans, this one features a blower wheel designed to repel lint and remain clog-free, says the manufacturer. It comes with a five-year no-clog no-maintenance guarantee and costs about $275. Tjernlund Products, 800/255-4208, tjernlund.com
