Hello, Patsy -
Fixya.com has no affiliation with MyPurMist.
This is the link to the company's home page:
Scroll down the home page to the bottom. There you will see the Customer Service telephone number, the Technical Service telephone number, and a Contact Us link (letter envelope icon.)
I recommend you call the Technical Service number during weekday business hours. Since you do not own a cellular (mobile) phone, you can use a traditional land line phone to make the toll free call.
