I got ill on vacation and it turned into Bronchitis and the coughing was terrible. I also have allergies/asthma which during this time of year (summer) is terrible. I put my Molekule next to my bed and I noticed that by morning my lungs were clearer and I slept through the night without waking and coughing. I'm better now and I still keep it by my bed at night. I sleep better because I breathe better. Thank you Molekule. Well worth the cost and I've tried everything on the market.
