Air purification device includes body case, electrolytic tank, electrolysis unit, sterilization tank, gas-liquid contact portion, air blower, opening, valve member that covers opening, and movement mechanism that moves valve member. Sterilization tank is disposed below opening, by movement mechanism, when valve member is separated from an opening edge of opening, opening is opened, the water including the active oxygen species of electrolytic tank is supplied to sterilization tank, when valve member hits the opening edge of opening, opening is closed, and the supply of the water including the active oxygen species of electrolytic tank to sterilization tank is stopped.

Various embodiments are directed to a coronavirus air sanitization/isolation system with anti-virus curtain. The system may include a group of anti-virus strips with attached separation magnets coupled to an air inlet housing mounted above (e.g., in an attic ceiling) in an enclosed space. The anti-virus strips may be coated with a saline and soap solution that attracts airborne droplets contaminated with the coronavirus and dissolves a fatty layer of coronavirus cell membranes to prevent cell replication of the coronavirus, thereby destroying the coronavirus. The air inlet housing may include exhaust ventilation fans, salt filters, a wick saturated with the saline and soap solution, an electro-static air filter, and a distribution air duct. The fans may be utilized to circulate an airstream containing the coronavirus through the anti-virus strips, the filters, the saturated wick, and the distribution air duct to remove the coronavirus while protecting occupants with uncontaminated air.
