Patented Technology Since 2017

Copper Powder Embedded Material,

Not Just a Coating

​Sterilizes Your Mask in 3 Hours

PATENTED TECHNOLOGY

The SafeLean Anti-Bacteria Mask Case utilizes patented technology to sterilize your mask in 3 hours.  A copper powder embedded in the case material performs an antibacterial function and also deodorizes your mask.  "For thousands of years, long before they knew about germs and viruses, people have known of copper's disinfectant powers."  This technology was patented in 2017 and has been utilized as sterilization sheets installed in hospitals, daycare centers, apartments, and more.

COPPER RAPIDLY INACTIVATES VIRUSES

IN 2008, THE US EPA APPROVED THE REGISTRATION OF ANTIMICROBIAL COPPER ALLOYS THAT CLAIMED TO KILL "SUPERBUGS" LIKE MRSA WITHIN TWO HOURS AT ROOM TEMPERATURE.

IN 2015, A STUDY DEMONSTRATED THAT RESPIRATORY VIRUSES EXPOSED TO COPPER WERE COMPLETELY DESTROYED WITHIN A FEW MINUTES.

​

"Using Copper to Prevent the Spread of Respiratory Viruses"

​

Science Daily     November 10, 2015

"On copper, and a range of copper alloys -- collectively termed 'antimicrobial copper' -- the coronavirus was rapidly inactivated (within a few minutes, for simulated fingertip contamination)."

​

"Exposure to copper destroyed the virus completely and irreversibly."

​

"Human coronavirus, which also has ancestral links with bat-like viruses responsible for SARS and MERS, was found to be permanently and rapidly deactivated upon contact with copper.  What's more, the viral genome and structure of the viral particles were destroyed, so nothing remained that could pass on an infection.  With the lack of antiviral treatments, copper offers a measure that can help reduce the risk of these infections spreading."

IN MARCH OF 2020, A STUDY FOUND THAT SARS-COV-2 WAS INACTIVE ON COPPER AFTER 4 HOURS.

​

"Aerosol and Surface Stability of SARS-CoV-2 as Compared with SARS-CoV-1"

​

New England Journal of Medicine     March 17, 2020

"On copper, no viable SARS-CoV-2 was measured after 4 hours."

 

"We found that the stability of SARS-CoV-2 was similar to that of SARS-CoV-1 under the experimental circumstances tested.  This indicates that differences in the epidemiologic characteristics of these viruses probably arise from other factors, including high viral loads in the upper respiratory tract and the potential for persons infected with SARS-CoV-2 to shed and transmit the virus while asymptomatic."

THE OBSERVED DIFFERENCES IN INACTIVATION TIMES BETWEEN THE 2015 STUDY AND THE 2020 STUDY WERE QUESTIONED AND ADDRESSED.  IN CONCLUSION, THE 2015 STUDY AND A VARIETY OF LABORATORIES ACCURATELY DEMONSTRATE THE RAPID INACTIVATION OF VIRUSES WHEN EXPOSED TO COPPER.

​

"Can Copper Help Fight COVID-19?"

​

Advanced Materials & Processes    May/June Issue 2020

"These two articles ... used different strains of coronavirus but this is unlikely to be the source of the observed differences in inactivation times.  The anti-coronavirus activity of copper alloys probably extends to all strains of coronavirus because this class of virus is essentially structurally identical."

 

"Scientists believe that the differences in exposure times ... result[ed] from technical differences in the experimental protocols and not from inherent differences among the viral strains."

​

"These two factors, drying time of the inoculum and surface preparation, are the most likely factors affecting the inactivation time."

"Gyeonggi-do Integrated Civil Servants Union Joins the Campaign to Donate Good Masks"

Wikitree     May 21, 2020

"On the 21st, the Gyeonggi-do Integrated Civil Servants Union donated antibacterial mask cases from One International, a small and medium-sized company in Pocheon, at the northern government office of the provincial government office."

​

"The donated mask cases are made of an 'antibacterial copper film', a fabric patented by One International, and has an antibacterial treatment so that the mask can be used longer (recommended 3 months)."

​

"Chun-saeng Kim, CEO of One International, said, "We hope that it will be helpful to neighbors who need to wear the same mask every time because it is difficult to purchase a mask amid the continuing Covid-19 situation.  We will continue to help overcome Covid-19 through various products."
