Marketing Claim Verified by UL Solutions
UV reduces bacteria by 99.9% during the powered charging cycle
Verification Method
The following organisms were used during the assessment of this verification: Staphylococcus aureus (ATCC 6538) Escherichia coli (ATCC 2592) Test microorganisms were applied to the earbud gel and inner mesh of the earbuds. The earbuds were placed into the powered charging case. Closing the case lid completely contains the UV light source and activates a 10-minute UV exposure cycle. Before and after the UV exposure cycle, samples of the bacteria were extracted and analyzed for microbial counts and the reduction of test organisms were calculated. After each test run, negative control samples (no test microorganisms applied to the samples) were used to monitor any carryover of organisms from one cycle to the next. For each test run, the following calculations were made: Percent Reduction = (ACC – ATC)/ACC x 100 Log Reduction = log ACC – log ATC or alternatively log (ACC/ATC) Where: ACC = average Positive Control Sample organism count before cycle (cfu/mL) ATC = average Test Sample organism count after cycle (cfu/mL)
