Part of the Brookaire Family
In October 2026, Puremaxx Filtration Solutions joined Brookaire, uniting two veteran-founded HVAC filtration companies. Founded in New Jersey in 1974, Brookaire is a third-generation, family-owned manufacturer and distributor of commercial and industrial HVAC filtration products. Our families have known each other for generations, and our companies have worked closely together since 2019.
What stays the same: our name, our Knoxville team and facilities, and your Puremaxx representative. Your pricing, contracts, ordering and payments haven’t changed either.
What you gain: access to Brookaire’s expanded products, technology and manufacturing capacity. That includes in-house custom and standard ring panels, custom-size filters with 48-hour turnaround, a broader filter and belt range, and wider geographic coverage.

2005
Doug H Rochat takes over ownership and the name is slightly modified to AFD Industrial Filters as the company enters new markets outside of air filters
2019
Son-in-law Chuck Kennedy takes over ownership, bringing in generations 4 and 5, and the name is changed to PUREMAXX FILTRATION SOLUTIONS to become the most trusted partner to mechanical contractors and large facility maintenance personnel for innovative filter strategies and newly added services, including jobsite delivery, job sorting, V-belt sales and in-house custom manufacturing of pleated filters.
2021
Manufacturing of custom-size filters increased with the addition of another production line. This allowed us to increase our output substantially and grow our production team to handle large custom jobs very quickly and efficiently.
2023
With our new facility finished (right next door), we relocated our operations, leaving our original facility to become our offices and high-purity filtration storage. This exciting improvement gives us substantial efficiency gains and capacity for our future growth!
2024
3rd facility opened to facilitate storage for all types of final filters, including bags, mini pleats, rigid cells, ASHRAE, V-cells and HEPA filters. This facility is also used for staging full truckload orders.
