The National Air Filtration Association
The National Air Filtration Association(NAFA) has completed development of the NAFA Product Certification (NPC) program. The program will ensure that end users of air filtration products have access to accurate, verifiable information when selecting air filtration products. The NPC program was meticulously developed over a five-year period and allows for the independent, third-party verification of filter performance using the ASHRAE 52.2 standard for testing filter efficiency based on particle size. The NPC program will help air filtration practitioners ensure that the products they use meet the specifications of each filtration application.
