regulations contained in the California Code of Regulations (CCR), Title  20 (the "Proposed 
Action"). The CEC proposes to update the testing, certification, and marking requirements 
for air filters. The CEC proposes modifying the existing scope for air filters to clarify that 
only air filters for ducted systems are covered by t he regulation. The CEC also proposes 
to update the test procedures to the most recent iterations of the American National 
Standards Institute/American Society of Heating, Refrigerating and Air -Conditioning 
Engineers Standard 52.2 -2017 and the Air -Condition ing, Heating, and Refrigeration 
Institute Standard 680 (I -P)-2017 test methods. The proposed regulation allows the size 
of the filter used for testing to be chosen by the manufacturer as the basic model for the 
filter family. The certification and marking requirements have been updated to be 
consistent with the updated test procedures described above.
