※1 “Perfect Interior Air Clean”

Release date: October 2017

Product features:Ultra-low odor, air purification, and antibacterial and antivirus properties realized through photocatalytic reaction

※2 Mechanism of photocatalysis

Active oxygen species produced by photocatalytic reaction inhibits the activation (infectious ability) of viruses through oxidative breakdown of outer membrane (envelope or capsid) of virus particles. Photocatalytic test results show that “Perfect Interior Air Clean” is effective against general strains of virus but do not guarantee protection against all virus families or specific virus strains.

Antibacterial tests were performed using Staphylococcus aureus and antivirus tests using bacteriophage Qβ.
