@tomasgomezpro @jobemine @navedelmisterio Los filtros HEPA H13 portátiles pueden eliminar los aerosoles del aire incluidos aquellos en los que se encuentra el virus. El curso pasado hicimos un estudio en las aulas y con PCR detectamos el virus en los filtros. Este otro estudio es unas compañeras https://t.co/qXqu1KHtOP

@jaxPYL THIS one measures spread of virus particles before and after the introduction of a portable air cleaner, and YES, you can apply a household to a classroom. https://t.co/XZzwFKNZZn Their last argument is so bad. “Our space is so crowded and unventilated there’s no point trying.”

@PaisleyJanine @beccyjanehealey Vaccination is only one line of defence. The more precautions the better. Bringing back masks in essential services is an easy way to reduce transmission. Dr Cameron Jones presentation on portable #HEPA filters is very interesting. https://t.co/CQRemRgFNv
