Seriously, you need a lab to know if these things work - so keep that in mind. But the idea is to try and remove airborne droplets that can be spread by infected people at family gatherings. PRO - Lots of speed settings to adjust fan noise to environment - Vendor included a temp/hygrometer gauge, a nice plus although it's somewhat orthogonal to the purpose of the air purifier - May help reduce transmission of COVID-19 CONS - How do I know if it works? - More fans? More noise. It's a complex problem and it's not fully resolved here, but that shouldn't come as a surprise. At our meeting, some people wouldn't allow me to turn it on at full power. For most suburban living rooms, this model may not be powerful enough. The controls don't say much. GENERAL It is difficult to tell if the space is too big for a car. Smaller spaces with a fully loaded machine are probably best suited. You can close the door, but most rooms are not airtight, so the s/b score is 500m².
