Sorry guys but that is not an acceptable reply.
Why do you think it is a bad idea? We are talking trace amounts. Perhaps a mint leaf or a vanilla drop in the 4 litre supply container.
If you like or don`t like something lets hear why.

Where I use my CPAP gear the air smells a bit. I seem to remember people adding a trace of odorant to help "freshen" the air from the humidifier.
Anyone on this forum tried this.? I`m talking TRACE amounts of odorant like water soluble mint or perhaps peppermint.
