Humidifier Sanitizer


Oxy Co. Ltd, a local company in Korea, launched a Humidifier Sanitizer (HS) product in 1996. It was one of a number of companies involved in manufacturing HS products.

In March 2001, RB acquired Oxy Co. Ltd to become Oxy RB. In 2011, the Korean Centre for Disease Control (KCDC) released an announcement on the results of a study which suggested a link between HS products and reported lung and respiratory injuries and deaths. Following the KCDC announcement, Oxy RB began to voluntarily withdraw its HS product from the market. Oxy RB has since participated in all investigations to understand fully the HS issue and bring resolution to HS victims and their families.

Oxy RB has expressed its sincere apologies to all victims of the HS tragedy in Korea and stated absolutely its determination to do the right thing for the victims and their families.

Consumer safety remains Oxy RB’s number one priority and we have taken steps to review our safety and escalation processes so that something like this will never happen again.
