IONPURE® Antiviral Agent
About IONPURE
IONPURE
is an inorganic antibacterial agent composed of 100% glass powder.
IONPURE consists of soluble glass microparticles containing antibacterial metal ions.
Glass is generally associated with bottles and windows, so it may be difficult to imagine glass dissolving in water. However, glass can be made water-soluble by modifying its composition.
Antiviral Properties of IONPURE
Testing has confirmed that a new IONPURE glass-based antibacterial agent reduces the amount of three viruses: SARS-CoV-2, influenza A virus, and feline calicivirus (a surrogate for norovirus).
