PUREMAXX IS A 4TH GENERATION COMPANY LOCATED IN KNOXVILLE, TN

We specialize in finding solutions to the needs of both mechanical contractors and in the commercial/ Industrial sectors. Whether its consolidating filter vendors, just in time job-site deliveries custom size filters or indoor air quality equipment….we have you covered!

Puremaxx roots go back to 1964 when John S Rochat began Rochat Heating and Air Conditioning in Knoxville. The motto then was “fast personal service” and that policy has never changed. Responsiveness to every customer inquiry and need is given utmost attention.

In 1998 the sales and service of HVAC equipment was sold, and only the filter business was retained. It was renamed AFD Industrial Filters.

In 2019 the 3rd and 4th generation entered the business and launched the Puremaxx brand to incorporate fresh direction and vision.
