The certification or certification system that is mentioned here is used for extensive term of conformity assessment for international standard conformity, etc. which is performed by the Korea Accreditation Board (KAB).
Conformity assessment means substantiating whether or not a product, process, system, person or agency meets the requirements and regulations. Testing, inspection, product certification, management system certification, qualified certification, etc. are included in that field. 
KMAR is certification system that is conducted by Korea Management Association Registration Inc. (KMAR), and it evaluates and certifies independently/objectively whether the management system of an enterprise complies with the requirements of the international standard properly by managing the organization’s related resources effectively/efficiently and improve continuously through the establishment of ISO certification system.

This system is to evaluate whether the manufacturer has the ability to produce the end product that meets the requirements of UL by testing and evaluating the appropriate UL standard requirements. In general, the manufacturer substantiates this by proving the ability to produce a final product according to UL’s safety requirements.
National Air Filtration Association (NAFA) is a non-profit trade association. Aiming for integrity and professionalism of air filtration products, NAFA consists of the companies with the highest standards.
To become a member of NAFA, the enterprise has to pass the qualification for expertise of air filtration, manufacturing method, and testing for a wide range of air filtration applications.
