# Viruses Source: https://cpolar.tech/contaminants/viruses/ This is the text of that page. The page itself builds its screens inside iframes, so this file carries the same words in a form a machine can read. Nothing here is paraphrased. --- Viruses travel the air to infect — C-POLAR Viruses travel the air to infect, and many are negatively charged Many respiratory viruses spread through shared indoor air. Outbreak investigators have traced SARS-CoV-2 along a restaurant’s air-conditioning and across a quarantined cruise ship . Once inhaled, they cause colds, flu, and COVID, and studies link infection to lasting heart and brain effects . Many airborne viruses carry a negative charge . About 100 nm A Human Hair: 70,000 nm --- Viruses — Health Impact — C-POLAR What the viruses do inside you --- The filter — virus The filter keeps the virus it catches alive . 21 days a live virus stayed infectious on filter media. The media holds it. It does not kill it. A conventional filter catches the virus, but it does not kill it. Trapped in the fibers, the virus stays infectious for days. Canada's National Microbiology Laboratory recovered live, infectious virus from filter media 21 days after it landed, long after the person who breathed it out had gone. French researchers pushed an airborne virus through a real air-handling filter. It trapped most of it, but about 500 infectious particles still passed through . In another test, virus on an air-handling filter was still infectious after ten hours of running air , the airstream does not clear it out. The EPA tells the workers who change these filters to put on gloves, goggles, and a respirator first. The filter meant to clean the air becomes a store of live virus, held in the fibers the building's air keeps passing through. --- Captures the virus. Destroys it. — C-POLAR Airborne virus about 1 million infectious units per trial 1.3 m/s airflow NanoFlashing Control NanoFlashing captures the virus , and destroys it 99.99% of the virus it caught, destroyed, not just trapped Independent testing shows NanoFlashing™ destroys up to 99.99% of a broad spectrum of viruses through a physical mechanism.
