+1. Together with a test in the same environment without a purifier at all. PM count drops down to almost 0 in a room with closed windows with a breathing person inside. Lungs of a person act as a perfect purifier.
- OJFord 7y ago> Lungs of a person act as a perfect purifier. Is that good? I mean, of course it's good that PM doesn't just pass straight into our bloodstream, but isn't our lungs doing the purifying exactly the thing that people try to avoid with mechanical air purifiers?
- cosmolev 7y agoIt is bad of course! PM does pass straight into our bloodstream. I was just talking about the test setup. A test of any purifier should be compared to a test with a person in a room without purifier. Otherwise those results are not significant.
- lm28469 7y agoThe whole point of filtering air for PMs is to avoid having them in your lungs so I'm pretty sure that's not "good".
- OJFord 7y agoYes, that is what I said.
- oiasdjfoiasd 7y agoLOL. Isn't that exactly the reason why you want a Purifier .
