Antiviral Filter Virus Guard Healthcare Products
Effective against COVID-19 virus (SARS-CoV-2) !!
An antiviral performance test of Virus Guard against the COVID-19 virus (SARS-CoV-2) was conducted by Japan Textile Products Quality and Technology Center (QTEC). And it has been confirmed that it is effective in reducing 99.9987% of the COVID-19 virus (SARS-CoV-2) in only one hour.
*1 Conducted using a test method in accordance with ISO21702.
Please note that this demonstration is an evaluation in a laboratory, and does not indicate the effect in an actual use environment.
It does not assure absolute efficacy in the prevention of COVID-19 infections.
How to reduce viruses?
Viruses are reduced by two forces, copper ion and reactive oxygen species.
Antiviral and Antibacterial mechanism
-
When monovalent copper compound nanoparticles contact with viruses or bacteria, monovalent copper ions elute in moisture.
-
Monovalent copper ions react with oxygen and reactive oxygen species are generated.
-
Copper ions and reactive oxygen species reduce viruses and bacteria.
The high oxidizing power of reactive oxygen species can denature and reduce the number of viruses.
Which viruses have been shown to be effective?
It has been shown to be effective against a wide range of viruses, regardless of the presence or absence of an envelope, such as Influenza viruses with an envelope which is similar structure to the new coronavirus.
| Microorganism Species | Classification | Name | Strain name |
|---|---|---|---|
| Virus | with envelope | Influenza virus A/H1N1 | A/New Jersey/8/76 |
| A/PR/8/34 | |||
| A/Califormia/07/09 (Pandemic in 2009) | |||
| A/Swine/1976/31 (Swine influenza) | |||
| A/WS/33 | |||

| Mouse norovirus | S7 |
Furthermore, It is effective in reducing influenza virus by more than 99.99% in a very short time.
How is antiviral agent applied?
The size of inorganic nanoparticles are about 50nm, and it is coated on entire fibers without clogging when processed into filter materials.
