3.1 Disinfection and it's technology
• What are Hydroxyl radicals?
Hydroxyl radicals are produced by sunlight and trapped in the ozone as humid air. These natural substances
are harmless and are easily distinguishable from contaminants.
• How do hydroxyl radicals disinfect?
STEP 1
Hydroxyl radicals surround protection layer
of harmful bacteria or virus
3.2 Test Results
Tested by KCL (Korea Conformity Laboratories) / 2016. March 24th issued
TEST ITEMS
Antibacterial test for Escherichia coil
Antibacterial test for Pseudomonas aeruginosa
Antibacterial test for Staphylococcus aureus
Antibacterial test for Salmonella Typhimurium
Antibacterial test for K pneumoniae
Antibacterial test for MRSA
* A four-hour test is conducted on the surface to measure the device's air disinfection capability.
The test results show a 99.9% reduction rate.
TEST ITEMS
Reduction test for Airborne microbes
(Klebsiella pneumoniae)
