Worked for awhile
I bought this and I could not be more happy. I suffer with several lung diseases and just breathing is a issue. Just as a lark I installed this and was amazed at how I felt! No wheezing or coughing. I don't think people withouts lung issues would get the same results, but for the money it is worth a try. UNFORTUNATELY,, It quit working at the six month mark and that is outside of the Amazon warranty even thought it is warranted for 3years. I try to find out how to get in touch with the manufacturer and I find a Chinese company. The major reason that I bought it was because it said "made in the USA on it. Now I have my doubts..
