I have to sleep with a humidifier every night for my vocal chords. I have been using this product for 2 months with a humidifier that has to have a filter ugh I hate filters. The humidifier keeps my humidity above 50% and I run it constantly. This has kept it completely clean of that yellow orange stuff that always shows up on my filters in after a few days of running. Thank you. There is no smell and it only take a small amount so it will last me a while.
