Ozone Independent Testing

Verified to Meet Industry Standards

Our Products Exceed UL 2998's “Zero Ozone Emissions” Requirements

(UL 2998's “Zero Ozone Emissions” <5ppb of ozone)

 

When choosing an indoor air quality improvement system for your commercial or residential space, ensure it doesn’t produce any harmful by-products, including ozone. Ensure the system has been certified by an independent authority, such as Underwriters Laboratories (UL), to meet maximum ozone production levels of 50 parts per billion (PPB) or less.

Better yet, confirm that the system meets the stricter “zero ozone emissions” standard of no more than 5 PPB (that’s comparable to 5 seconds in 32 years!), and ask to see the test results that prove it.

  • What are PPM and PPB?

     

    The NIWA (National Institute of Water and Atmospheric Research of New Zealand) describes it best.

    PPM and PPB are units used in atmospheric chemistry to describe the concentration of gases. PPM stands for parts of gas per million parts of air, and PPB is parts per billion.

     

    If that's not easy to imagine, try these examples:

    Part Per Million (PPM):

    • 1 second in just under 2 weeks.
    • 1 litre of water in a swimming pool.

     

    Part Per Billion (PPB):

    • 1 second in 32 years.
    • 1 ml of water in a swimming pool (that's about the size of a sugar cube).

  • What is CSA?

     

    CSA: Canadian Standards Association

    The CSA labels are certified by CSA International, a Canadian group that offers  certification for electrical products, mechanical products, or ‘at risk’ ones in general. CSA is recognized around the world. The CSA logo, found on many products, indicates that the product, process and service have been tested according to Canadian or U.S. standards and that they comply with the requirements of this standard.

  • CSA C22.2 No.187:20 vs. UL 867

     

    CSA C22.2 No.187:20 

    • Addresses both chamber designed units (Section 7.4) and in-duct design units (Section 7.5).

      • Phenomenal Aire utilizes an in-duct design.

    • The CSA in-duct test is two 8-hour, single pass tests at (1) 375 CFM and (2) the highest flow rate the unit is designed to operate.

      • This test procedure replicates a more “real world” environment in which Phenomenal Aire products typically operate.

    • 50 PPB Limit.

     

    UL 867

    • Chamber Test Only.
    • Has provisions for allowing 8-hour tests under certain conditions.
    • 50 PPB limit.

  • How Does This Relate to UL 2998?

     

    UL 2998 Environmental Claim Validation Procedure (ECVP) for Zero Ozone Emissions from Air Cleaners accepts CSA C22.2 No. 187:20 as an equivalent procedure.

    "The product shall undergo Ozone Test as described by the Standard for Electrostatic Air Cleaners, UL 867, Section 40 or an equivalent ozone test. For some in-duct cleaning devices which are too large to fit in the UL 867 chamber or which may generate ozone in an enclosed compartment that may not be emitted without forced airflow, ozone measurement may be conducted according to CSA C22.2 No. 187-20.” (Section 5.3)
