You're joking right? An air purifier is designed to clean the volume of air in a room, not the entire planet!

Yeah?  Is that what I wrote?  

Let me break it down for you:  I personally run a purifier in each of my 3 condo rooms.  I keep my windows shut.  I breathe clean air.

Anyone who thinks that by closing their windows AND  .... here it comes .... not running a purifier but thinking that somehow the air inside will be different from the outside, that is what I questioned.

 

Got it now?  

I think they are doing a fine job.

yes, since the agencies responsible are doing nothing effective the air purifiers available are doing a good job.

3M's face masks are widely available and are inexpensive.

I can't find them in large sizes. Where should I look?
