Does clear the air in a glass, hopefully it works on germs and allergens in the air.
Just got the electronic air necklace. I turned it on. Nothing, no sound. I went back to advertisement and reread it. It suggested testing it which I did.  I burned some napkin (in the sink). And put it under each glass. By the time I got to second glass almost a minute elapsed.  Glass 1 was in the lead because I put napkin in it first. As I’m watching, the air In Glass 2 in which I had placed the necklace began swirling and completely cleared, way ahead of glass1.  Does the necklace work? Who knows? But it does clear the air..
