Unfortunately, #Covid19 has entered our household as well as my parents’ household for the first time since the pandemic began. I’m a little rusty since it’s been a couple of years since the last time I built a #corsirosenthalbox but there is an urgent need to expand our air filtration capability. Please be very careful out there, the virus is everywhere and it is extremely infectious. https://cdn.mastdn.ca/media_attachments/files/111/081/486/993/255/272/original/55e8e834aa2d34f3.jpeg
