Nixa-based Aire-Master of America Inc. has pumped up sales with a house brand, largely led by a deal with national retailer Bed Bath & Beyond Inc. (Nasdaq: BBBY). What started with Bed Bath & Beyond officials seeking a manufacturer for coffeemaker cleaners in spring 2011, Aire-Master executives have turned into a new product line called Nuvera that has amassed sales projected to reach $1.5 million by the end of the year. Through Bed Bath & Beyond, Aire-Master officials say 500,000 bottles of Nuvera coffeemaker cleaner sold in the first year of production through July, and the Nixa company is filling the retailer's orders daily through an electronic network.
