National Filters Corporation was started in 1968 by Arnold Goldberg and Cecil Nappier, selling air conditioner filters to commercial customers and service companies. Over the next 40 years responsibility for daily affairs was assumed by Mr. Nappier’s son, David, who is still with the company. During 2010, the company acquired the service division of Commercial Filter Maintenance to create National Filter Solutions, Inc. Today, National Filter Solutions is a leading provider of air conditioner filter sales and change services in its market area.
