Technical sheet
How PLASMA QUAD works
PLASMA QUAD filter works as an electrical barrier capable of capturing and neutralizing microscopic particles in suspension: by forming a high potential electric field and then discharging it, this air filtration system captures, inactivates viruses and removes pollutants that pass through it.
First phase:
- Generates plasma.
- Attacks mold and allergens. Inhibits viruses.
- Positively charges dust and PM2.5 suspended particles.
Second phase:
- Creates an electric field.
- Retains and traps positively charged PM2.5 dust and particles.
PLASMA QUAD air filtration system is tested against viral activation of SARS-CoV-2
Tests conducted at the Microbial Testing laboratory Kobe Testing Center of QTEC - Japan Textile products Quality and Technology Center have shown that PLASMA QUAD can successfully inactivate up to 99.8% of coronavirus (SARS-CoV-2).
The present test was conducted in the laboratory using the PLASMA QUAD air filtration system. The results may differ from using the product equipped with PLASMA QUAD in a real environment.
