I have a sunbeam 1387 warm mist humidifier. I need to know how to clean scale from the filter. It looks like it can be taken apart. Can it?

Actually, Carol, it shouldn't be necessary to take the unit apart. Mix a 50/50 solution of White Distilled Vinegar and Bottled Distilled Water (enough to fill the tank). Pour the solution in and allow it to sit overnight. Then empty the solution and fill the tank with Bottled Distilled Water. Turn the unit ON and allow it to run for 1 hour. Then empty any remaining Distilled Water. Doing all the aforementioned, should have not only cleaned the filter, but also the unit itself. If you use Bottled Distilled Water in the future, rater than tap water, the filter and the plumbing of the unit will stay clean longer and will require less maintenance.

Hope this helped you. Please let me know. Thanks.
