    FAN + AIR FILTER + TAPE. “filter stuck onto $20 box fan—cheap, and while it wouldn’t cut the risk of infection to zero, it would still pull virus-laden particles out of the air”. Prelim tests show results. @jljcolorado calls it a “brilliant idea.” #COVID19https://www.wired.com/story/could-a-janky-jury-rigged-air-purifier-help-fight-covid-19/ …

        I rigged one up when doing some home repairs a couple of years ago. They are very effective, but not quiet. Get white duct tape and seal it up tight around the edges - air takes the path of least resistance, and the filter is resistance.

        I built a UVGI system for around $150. It's not much more complicated than that, much more efficient. A couple of pieces ducting, an inline fan, lamp fitting, UVC LED, aluminium foil, two mesh vents. Yes kids, UV light is harmful, so make sure it's properly light sealed.

        The drawback of using a HEPA filter is it takes a lot of energy to suck air through. So you need a more powerful fans to get the same throughput of air. Also does not kill microbes, and they may pass through it.

        Die Idee ist auf jeden Fall nicht schlecht, kein Ersatz für Abstand, Mundnasenschutz, Lüften.. aber doch ein Ansatz wie vielleicht die Aerosolkonzentration in der Büroluft oder im Klassenzimmer im Winter bezahlbar reduziert werden kann. Studien sind notwendig.

        Indeed. Ventilation for better air quality is now one of the most important.
