February 24, 2022

Why do these certifications benefit you?

At Thermo King, we are committed to identifying technologies to help transit riders and drivers feel safer while getting back to their normal routines and using public transportation. Improving the Indoor Air Quality (IAQ) within a bus is top of mind and why we developed the Thermo King Air Purification Solution.

Keeping you safer from the things you can’t see

The California Air Resource Board (CARB) is a state agency responsible for protecting public health from air pollution. It affirms that products have passed specific performance and quality assurance tests. They have adopted a regulation to limit the amount of ozone emitted from indoor air cleaning devices in order to protect public health. All air cleaning devices sold in the California must meet the regulation requirements.

As a CARB approved electronic air cleaner, the Thermo King Air Purification solution has been independently reviewed and approved for sale in the state of California.

Commitment to quality and safety

While CARB certification is important, here is a list of four other certifications that Thermo King has secured for this product and why they are valuable.

  • UL 2998 certification

This procedure covers air cleaners which potentially generate ozone, are rated at 600 volts or less, are intended to remove or aid removal of dust, other particles, or pollutants from the air, and are intended for use in accordance with the National Electrical Code, ANSI/NFPA 70.

  • UL-900 flammability

This is an evaluation of the flammability and smoke density of air filter units. These requirements also cover media intended for assembly into air UL-900 flammability filter units.

  • Environmental Rating IP44

This means a product is protected against solid objects that are bigger than 1mm and water splashing from all directions. This is because of our Purification Method GPCO - Graphene-Enhanced Photocatalytic Oxidation.
