“Can't really tell a difference, I ordered 6 but I have one that has no light on it and cannot get any info other than about how you should clean every couple of weeks - its brand new! Not so sure about it!”
“It took me a while before I started using it after the purchase. But these things are great!! I can breathe and sleep so much better. The product is definitely worth the money spent”
“It was my first time to buy anything from this company, I bought a set of three and after four months one of them wasn't working. I taught they said that it will last about three years. We'll see with the other two plus I can not tell the difference from before using Plug-in Air and now. Very disappointing!!!.”
