The CAFS program distinguishes those professionals who have demonstrated a thorough, up-to-date understanding of air filtration technology and high level of professionalism. In order to become certified, air filtration professionals must pass an extensive examination on the principles, methods and applications of air filtration. Candidates for certification are also subject to compliance with the NAFA Code of Ethics. Certification is renewable on an annual basis pending successful completion of continued education requirements in order to demonstrate current and continued expertise.
When purchasing products or services from a Certified Air Filter Specialist, customers are assured that their particular requirements and needs will be addressed by a knowledgeable professional.

What do I need to study in order to pass the Certified Air Filter Specialist exam?
The 100 question (70 multiple choice, 30 true/false) CAFS Exam is based on the NAFA Guide to Air Filtration. In fact, every question comes straight out of the book! If you study the manual thoroughly you should have no problem passing the exam. We also recommend that you have at least one year of field experience in the air filter industry. NAFA does offer a series of recordings to help you study, however, if you have not read and understood the NAFA Guide to Air Filtration, you will probably not pass the exam. The CAFS Exam is strictly pass/fail based on the total number of correct answers. No other details will be released; correct or incorrect answers will not be shared. Samples test questions are not available.
