    I'm getting questions, so let me highlight this useful chart for selecting a HEPA air cleaner. Also remember: if you can, opening windows is really good. Avoid gimmicks and ionizers. HEPA + CADR (speed at which it cleans the air) is all that you should be looking for.https://twitter.com/marwa_zaatari/status/1433469347973017604 …

    This chart has the two CR boxes with 1 filter and 2 filters (name on chart starts with CR) tested by @DavidElfstrom - I updated Smart air for US version (120 V) and Austin air and added 2 more purifiers. - I made a list of all your requests. More purifiers coming very soon. https://twitter.com/marwa_zaatari/status/1432539974596022276 … pic.twitter.com/BUuDMhWLky

        Also, the picture in the above tweet is a Corsi-Rosenthal box. You can make one for about $100 and in 20 minutes (a box fan, A/C filters you can buy for cheap + duct tape) and it will work just as well as the expensive machines. Here are the instructions:https://www.wgbh.org/news/local-news/2021/08/17/diy-air-filters-for-classrooms-experts-are-enthusiastic-and-a-citizen-scientist-makes-it-easy …

        A related question - are air hand dryers in washrooms good or bad from a Covid aerosol perspective? I would think they are bad as they would make a mockery of the 6 foot rule as the air is going to be all mixed up and aerosols dispersed in the room.

        Here in California we have been having quite an uptick in bad air days. So we just bought our second Coway. Buy this brand and you will be satisfied, imho.

        Not wanting to spread misinformation… I thought I read that opening windows had a very limited improvement on air quality and that it comes nowhere near comparable to a well working hvac system that turfed air exchange… I’d still recommend opening windows but…
