We purchased your product several weeks ago and it has been a tremendous asset to me!  I suffer from sinus congestion and it is most troubling for me at night.  Our home does not have a humidifier built into our heating system, so in the winter time it is all dry heat.  At night when I’m sleeping, the dry air wreaks havoc on my sinuses.  We always knew that a humidifier would be beneficial and had tried several prior to purchasing your system.  What a difference!  It is so nice to wake up and be able to breath without having to use saline or other sinus medicines!  Thank you for this wonderful product!
