Filter division started. The HVAC division sold to Four Seasons Comfort and a new name is formed for the filter business (Air Filter Distributors or AFD for short)


 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


Son in-law Chuck Kennedy takes over ownership bringing in generation 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.


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 efficeintly. 


With our new facility finished (right next door) we relocated our operations in 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!
