 Appl.No 17849572 Applicant KKT Holdings Syndicate Inventor Tzu-Yi KUO

This invention provides a respirator for detecting viruses which cause respiratory tract infection. The respirator comprises an outer layer, an inner layer, a rapid screening reagent between the outer layer and the inner layer, and a water-resist membrane between the rapid screening reagent and the inner layer. A sample pad of the rapid screening reagent is located on a region close to the nostrils, such that air from the nostrils will arrive the sample pad. Viruses inside the air with vapors or moistures will flow inside the rapid screening reagent through a conjugate pad, a nitrocellulose membrane, and an absorption pad. At least one test line will indicate a corresponding virus.

The HV firewall filter facial respirator that captures, incapacitates, and kills viruses including coronavirus from the air being inhaled is disclosed herein. In an embodiment, the respirator comprises of a HV fire wall filter with three wire mesh electrodes: first filter electrode front with fine wire mesh made of wider aperture that permeates the air contaminated with virus to enter the HV firewall filter; second filter electrode centre with ultrafine wire mesh made of narrower aperture traps majority of the virus in the first electrode space between the electrodes; third filter electrode rear also with ultrafine wire mesh made of narrower apertures further traps the remaining virus in the second electrode space between the electrodes; and the trapped virus while passing through the electrode spaces gets electrocuted/burnt/cell structure destroyed, as a result of high voltage (near breakdown) applied to the electrodes, and the air coming out of the HV Firewall filter is nearly 99.99% free of virus.
