“I received these plugins but I can’t tell any difference. I had them plug in for a couple days. My coughing has not stopped so Im not sure if they are working or not. I get coughing allergies every year because of pulling weeds and dealing with dead grass in the Spring. I bought 10 but only plugged in 6 since I have a small house. I’m wondering maybe I plugged in too many in a house of 1,000 square ft.”
