In 1970, Filtronetics, Inc. was started with a $600 loan and a dream – to be the best custom filter maker in the business. Today, that dream is a reality. Housed in a modern 20,000 square foot facility in the heart of Kansas City’s Historic River Front District, we have built a reputation in the commercial and military communities as industry leaders when it comes to quality and expertise.
