(a) The following definitions refer to air purifiers:

1. (1) Air purifier, also known as room air cleaner, means an electric, cord-connected, portable appliance with the primary function of removing particulate matter from the air and which can be moved from room to room.

2. (2) Industrial air purifier means an indoor air cleaning device manufactured, advertised, marketed, labeled, and used solely for industrial use that is marketed solely through industrial supply outlets or businesses and prominently labeled as “Solely for industrial use. Potential health hazard: emits ozone.”

   (b) Standard requirements for air purifiers.

   Air purifiers, except industrial air purifiers, shall meet the following requirements, consistent with the standard levels from ENERGY STAR V1.2 specification for air purifiers, as incorporated by reference:

3. (1) clean air delivery rate for smoke shall be 30 or greater;
4. (2) for models with a clean air delivery rate for smoke less than 100, clean air delivery rate per watt for smoke shall be greater than or equal to 1.7;
5. (3) for models with a clean air delivery rate for smoke greater than or equal to 100 and less than 150, clean air delivery rate per watt for smoke shall be greater than or equal to 1.9;
6. (4) for models with a clean air delivery rate for smoke greater than or equal to 150, clean air delivery rate per watt for smoke shall be greater than or equal to 2.0;
7. (5) for ozone-emitting models, measured ozone shall be less than or equal to 50 parts per billion (ppb);
8. (6) for models with a Wi-Fi network connection enabled by default when shipped, partial on mode power shall not exceed two watts; and

9. (7) for models without a Wi-Fi network connection enabled by default when shipped, partial on mode power shall not exceed one watt.

   (c) Test methods.

10. (1) Test methods identified in Table 1 of this subdivision shall be used to determine compliance with the standards in subdivision (b) of this section. Table 1: Test Method for Air Cleaners
