Effects of atmospheric OH Radical on humans

  1. Nature’s Detergent

In the early 1970’s , Leeds university , in Great Britain , embarked on a program that asked the question , “What do hydroxyl radicals do ?” A University study found that , the activity of atmospheric hydroxyls was responsible for neutralizing some 2500 atmospheric chemicals by way of some 7000 reactions. For this reasons. For this reason , hydroxyl radicals found in the atmosphere have been calles “Nature’s Detergent”

  1. OH Radical is harmless

Hydroxyl radicals also attack the porous cell walls of bacteria and viruses which destroys them through the process known as cell lysing. Human , animal and plant cells are “Designed” to be in the sunlight and have cell walls that are porous and are not harmed by atmospheric hydroxyl radicals.

  1. Proof of Safety

OH  Radical has proven its stability through a number of domestic and international organization such as the Ministry of food and drug Administration.

Official letter of the NIEHS , USA : OH Radical is No harmless to human health.

Definition of OH radical by Korean Food and Drug Administration : It is a heterogeneous oxygen-anionic material that is generated by applying energy to the hydroxyl group (OH). It has excellent oxidizing power and is harmless to the human body.

Correlation between OH radicals and air purification in the atmosphere

Importance of OH Radical


  • Expected effects on COVID-19
  • Case 1 ) Disinfection – Generation of OH radical

OH radical removes hydrogen from the proteins that surround harmful bacteria and various viruses such as the coronavirus to destroy the protein structure and remove harmful microorganism. Then , it converts them into H2O molecules that are harmless to the human body.

Case2) Virus test result when using Wellis Disinfection Unit.

Coxsackie Virus Test (July 2018) which Causes Hand-food-mouth Disease (HFMD)

(July 2018 Laboratory in UNIVERSITAT BARCELONA TECH) Result 99.99% Reductions

As a result of various virus tests with the Wellis Disinfection Purifier (WADU-02) , it was confirmed that up to 99% was removed within 2 hours. At present , it is difficult to directly test the COVID-19 , and the effect against COVID-19 can be inferred according to the results of RSV virus with 92% similarity.
