Wellisair: Ozone emissions

Test report (nº 103502990CRT-001): April 30th, 2018 Intertek Group plc (New York)

Scope: verify Wellisair's ozone emissions to meet with the standard "Electrostatic Air Purifiers, UL867, Section 40, 2016". To meet the criteria, the emittance of ozone cannot exceed a concentration of 0.050ppm.

Procedure: Wellisair was ubicated in a test chamber and measures were done in five locations with the following equipment: ozone calibrator Teledyne 703E; ozone monitor Teledyne 400E; temperature transducer Vaisala HMD-70Y and flow meter ST75V. After checking the two points with higher concentrations, the measures were applied with/without solution and in day/night mode for 8 hours.

Results:

Conclusions: Wellisair has been found to meet the criteria with a maximum emission of 0,016ppm not exceeding the allowed concentration of 0.050ppm. Furthermore, a second Wellisair was not required to be tested according to UL867, as the first sample’s maximum emissions were less than 0,030ppm, which satisfies the exception in the section 40.1.1.
